Types of Credit and How They Work: A Comprehensive Guide to Revolving Credit, Installment Loans, and Open Credit

KEY TAKEAWAYS

  • Credit falls into three main categories: revolving credit, installment credit, and open credit, each with distinct characteristics and uses.
  • Revolving credit, like credit cards, allows you to borrow repeatedly up to a credit limit and offers flexible repayment options.
  • Installment loans require fixed monthly payments over a set term and include mortgages, auto loans, student loans, and personal loans.
  • Having a mix of different credit types can positively impact your credit score by demonstrating your ability to manage various forms of debt.
  • Each credit type comes with specific advantages, disadvantages, and appropriate uses depending on your financial needs and goals.

Understanding the different types of credit available to consumers is essential for making informed financial decisions and building a strong credit profile. Credit is not a one-size-fits-all product. Different forms of credit serve different purposes, carry different costs, and affect your credit score in different ways. Whether you are financing a home, paying for education, covering emergency expenses, or making everyday purchases, knowing which type of credit best fits your needs can save you money and help you use credit responsibly. This comprehensive guide explores the three main categories of credit, how each works, their advantages and disadvantages, and strategies for using them effectively.

The Three Main Categories of Consumer Credit

Consumer credit falls into three primary categories that differ in structure, repayment terms, and typical uses. Revolving credit allows you to borrow repeatedly up to a set limit, making payments based on your balance and borrowing again as you pay down debt. Installment credit requires you to repay a fixed amount in regular payments over a predetermined period. Open credit must be paid in full each period and is less common than the other two types. Each category encompasses multiple specific credit products designed for particular purposes.

The Consumer Financial Protection Bureau regulates many forms of consumer credit and provides resources to help consumers understand their rights and obligations when using credit products. Federal laws including the Truth in Lending Act require lenders to disclose credit terms clearly, allowing consumers to compare options and understand the true cost of borrowing.

1. Revolving Credit: Flexibility and Ongoing Access

Revolving credit is the most flexible form of credit and the type most commonly used by American consumers for everyday purchases. With revolving credit, lenders approve you for a maximum credit limit, and you can borrow any amount up to that limit, repay it, and borrow again without reapplying. The amount you owe fluctuates or revolves based on your borrowing and payment activity.

Credit Cards: The Most Common Revolving Credit

Credit cards represent the most widely used form of revolving credit. When you are approved for a credit card, the issuer assigns you a credit limit based on your creditworthiness, income, and other factors. You can use the card to make purchases up to that limit, and as you pay down your balance, that credit becomes available again. Credit cards typically charge interest on balances carried from month to month, though most offer a grace period of 21 to 25 days during which you can pay off new purchases without incurring interest.

According to the Federal Reserve, revolving credit accounts for approximately $1.1 trillion in consumer debt as of 2024. Credit cards offer several advantages beyond simple purchasing power. Many cards provide rewards programs offering cash back, points, or miles on purchases. Consumer protection features often exceed those of debit cards, including zero liability for fraudulent charges and the ability to dispute charges. Travel benefits, purchase protection, and extended warranties add value for many cardholders.

However, credit cards also present risks, particularly for those who carry balances. Average credit card interest rates typically range from 16% to 24% or higher, making them among the most expensive forms of consumer credit. Minimum payments are often calculated at 1% to 3% of the balance, which means paying only the minimum can take years to eliminate debt and cost thousands in interest. Late payment fees of $30 to $40 and over-limit fees add to costs. The ease of using credit cards can also encourage overspending, leading to debt accumulation that becomes difficult to repay.

Home Equity Lines of Credit

A home equity line of credit, commonly called a HELOC, is another form of revolving credit secured by your home. Lenders approve you for a credit line based on your home equity—the difference between your home’s value and your mortgage balance. During the draw period, typically five to 10 years, you can borrow money as needed up to your credit limit, often using checks or a card linked to the account. You make interest-only payments during the draw period, though you can pay down principal if you choose.

After the draw period ends, the line enters the repayment period, usually 10 to 20 years, during which you can no longer borrow and must repay the outstanding balance through regular principal and interest payments. HELOCs typically offer variable interest rates tied to the prime rate, making payments somewhat unpredictable as rates change. However, because they are secured by real estate, HELOCs generally offer significantly lower interest rates than credit cards or personal loans.

HELOCs work well for expenses that occur over time, such as home renovations completed in phases or college tuition paid semester by semester. The ability to borrow only what you need when you need it helps minimize interest costs compared to taking a lump sum. Interest on HELOCs may be tax-deductible if the funds are used to substantially improve the home securing the loan, though tax law changes have placed restrictions on this deduction. The primary risk of HELOCs is that your home serves as collateral, meaning failure to repay could result in foreclosure.

Personal Lines of Credit

Personal lines of credit function similarly to credit cards but typically offer higher credit limits and lower interest rates for well-qualified borrowers. Banks and credit unions offer these unsecured lines of credit to customers with strong credit profiles. You can draw funds up to your credit limit, usually by transferring money to your checking account, and pay interest only on the amount borrowed. Minimum monthly payments typically include both interest and principal, gradually reducing your balance.

Personal lines of credit can be useful for managing irregular expenses or as an emergency fund alternative, providing access to cash when needed without carrying a balance and paying interest during months you do not use it. However, these products are less common than credit cards and often require strong credit and banking relationships to obtain. Interest rates vary widely based on creditworthiness but generally fall between credit card rates and secured loan rates.

2. Installment Credit: Structured Repayment Plans

Installment credit, also called installment loans, provides a lump sum of money upfront that you repay through fixed payments over a predetermined period. Each payment includes both principal and interest, and the loan is fully amortized, meaning you owe nothing when the final payment is made. Unlike revolving credit, once you repay an installment loan, the credit line does not automatically replenish, and you would need to apply for a new loan if you needed to borrow again.

Mortgages: The Largest Installment Loans

Mortgages are installment loans used to purchase real estate and are typically the largest debts consumers will ever carry. Traditional mortgages span 15 to 30 years, though other terms exist. Lenders secured by the property being purchased, which reduces lender risk and allows for relatively low interest rates compared to unsecured debt. Monthly payments include principal, interest, property taxes, and insurance, often abbreviated as PITI.

Fixed-rate mortgages maintain the same interest rate throughout the loan term, providing predictable monthly payments. Adjustable-rate mortgages start with a lower initial rate that adjusts periodically based on market conditions, typically offering lower payments initially but creating payment uncertainty later. The total interest paid over the life of a mortgage can equal or exceed the original loan amount, particularly for 30-year loans. However, mortgage interest is often tax-deductible, reducing the effective cost of borrowing for homeowners who itemize deductions.

Qualifying for a mortgage requires demonstrating sufficient income, manageable debt-to-income ratios, adequate down payment funds, and good credit history. Most lenders prefer credit scores above 620 for conventional loans, though government-backed programs may accept lower scores. The mortgage process involves extensive documentation of income, assets, employment, and creditworthiness, making it one of the most rigorous credit application processes consumers face.

Auto Loans: Secured Financing for Vehicles

Auto loans are installment loans used to purchase vehicles, typically spanning three to seven years, though some lenders offer longer terms. The vehicle serves as collateral for the loan, allowing lenders to offer better rates than unsecured loans. If you default on an auto loan, the lender can repossess the vehicle to recover their losses. Monthly payments depend on the loan amount, interest rate, and loan term, with longer terms reducing monthly payments but increasing total interest paid.

Interest rates on auto loans vary significantly based on creditworthiness. Borrowers with excellent credit may secure rates below 5%, while those with poor credit might face rates of 15% or higher. New car loans typically offer lower rates than used car loans because new vehicles depreciate on a more predictable schedule and maintain higher values, reducing lender risk. Many auto manufacturers offer promotional financing, sometimes as low as 0% APR, to boost sales of new vehicles.

A significant risk with auto loans involves owing more than the vehicle is worth, called being underwater or upside down on the loan. Vehicles depreciate quickly, particularly in the first few years, while loan balances decrease more slowly, especially with longer loan terms. If you need to sell the vehicle or if it is totaled in an accident, you may owe more than the vehicle’s value. Gap insurance can protect against this risk for financed vehicles.

Student Loans: Financing Education

Student loans help finance higher education costs and are typically structured as installment loans with repayment beginning after graduation. The U.S. Department of Education offers federal student loans with fixed interest rates set by Congress, flexible repayment options, and borrower protections including deferment, forbearance, and income-driven repayment plans. Federal loans do not require credit checks for most borrowers, making them accessible to students without established credit histories.

Private student loans from banks and other lenders supplement federal loans but typically require credit checks and cosigners for students without credit history or income. Private loan interest rates vary based on creditworthiness and may be variable or fixed. Private loans generally offer fewer protections and less flexible repayment options than federal loans, making them a second choice for most borrowers after exhausting federal loan options.

Student loan debt has reached historic levels in the United States, with many graduates carrying balances of $30,000 to $100,000 or more. However, student loans can be worthwhile investments when they enable higher earning potential through degrees in in-demand fields. Borrowers should carefully consider expected future income against loan amounts and choose realistic repayment plans. Federal income-driven repayment plans cap payments at a percentage of discretionary income and offer loan forgiveness after 20 to 25 years, though forgiven amounts may be taxable.

Personal Loans: Unsecured Installment Borrowing

Personal loans are unsecured installment loans used for various purposes, from debt consolidation to home improvements to major purchases. Because they are not secured by collateral, personal loans typically carry higher interest rates than secured loans but lower rates than credit cards for borrowers with good credit. Loan amounts typically range from $1,000 to $50,000, with repayment terms of two to seven years.

Personal loans work well for consolidating high-interest credit card debt into a single payment at a lower rate, financing large expenses that do not require specialized loans, or covering emergency costs when savings are insufficient. The fixed payment schedule makes budgeting predictable, unlike revolving credit where minimum payments fluctuate. Some lenders charge origination fees of 1% to 8% of the loan amount, which can be deducted from the disbursement or added to the loan balance.

Online lenders have made personal loans more accessible, often offering faster approval and funding than traditional banks. However, interest rates vary dramatically based on credit scores. Borrowers with excellent credit might secure rates around 6% to 10%, while those with fair credit could face rates of 20% to 30% or higher. Comparing offers from multiple lenders helps ensure you receive competitive terms.

3. Open Credit: Pay in Full Each Period

Open credit, also called charge accounts, requires you to pay the full balance each billing period and does not allow carrying a balance or making partial payments. This type of credit is less common than revolving or installment credit but serves specific purposes for certain consumers and businesses.

American Express charge cards are the most prominent example of open credit for consumers. Unlike American Express credit cards, which offer revolving credit, charge cards require full payment each month. If you cannot pay the full balance, late fees and other penalties apply, and the account may be suspended or closed. The advantage of charge cards is that they typically have no preset spending limit, giving high-spending consumers more flexibility than credit cards with fixed limits. Additionally, because balances must be paid in full, users avoid accumulating interest charges that build up with revolving credit.

Utility companies use a form of open credit where you receive service throughout the billing period and pay the full amount due by the payment deadline. Cell phone plans, internet service, and traditional utilities follow this model. Failure to pay results in service disconnection and potential damage to your credit if the account is reported to credit bureaus or sent to collections. Some utilities report payment history to credit bureaus, allowing responsible payment to help build credit, while others only report negative information.

How Different Credit Types Affect Your Credit Score

Credit scoring models consider the types of credit you use when calculating your score, with this factor accounting for approximately 10% of your FICO score. Having a mix of different credit types—both revolving accounts and installment loans—demonstrates your ability to manage various forms of debt responsibly. However, this does not mean you should open accounts you do not need simply to diversify your credit mix.

Revolving credit affects your score primarily through utilization ratios. Using high percentages of available credit on cards can significantly lower your score, even if you pay on time. Keeping utilization below 30% on each card and overall is recommended, with lower utilization producing better scores. Installment loans affect your score differently. While they contribute to credit mix and payment history, they do not have a utilization component in the same way revolving credit does. However, the relationship between your current balance and original loan amount can influence your score, with lower balances relative to original amounts being favorable.

The impact of payment history is consistent across credit types. Late payments hurt your score whether they occur on credit cards, mortgages, or student loans. However, different types of late payments may carry different weights. A 30-day late payment on a mortgage might impact your score more severely than the same late payment on a retail credit card, though all late payments should be avoided.

Choosing the Right Type of Credit for Your Needs

Selecting appropriate credit types for your financial needs requires understanding the strengths and limitations of each option. Credit cards excel for everyday purchases, emergencies, earning rewards, and purchases requiring consumer protections, but they are poor choices for large purchases you cannot pay off quickly due to high interest rates. Using credit cards for balance transfers to consolidate debt at promotional rates can be effective if you can pay off the balance before the promotional period ends.

Installment loans work best for large, one-time expenses with predictable costs. Mortgages finance home purchases with long repayment periods matching the useful life of the property. Auto loans spread vehicle costs over several years, though paying cash or making large down payments saves interest. Personal loans consolidate high-interest debt or finance major expenses where specialized loans are unavailable or inappropriate. Student loans invest in education with the expectation of increased earning potential offsetting the debt burden.

Home equity lines of credit provide flexible access to large amounts of credit at relatively low rates, making them suitable for ongoing projects or expenses. However, using home equity for depreciating assets like vehicles or vacations is generally inadvisable, as you would be pledging your home as collateral for purchases that lose value quickly. HELOCs make the most sense for home improvements that increase property value or for consolidating higher-interest debt when you have the discipline to avoid running up new debt.

Understanding the True Cost of Credit

The Truth in Lending Act requires lenders to disclose the annual percentage rate and other key terms in a standardized format, allowing consumers to compare the true cost of credit across different products. The APR includes not just the interest rate but also certain fees and charges, providing a more accurate picture of borrowing costs.

For revolving credit, APRs can be deceiving because they assume you carry a balance for a full year, which may not reflect your actual usage. If you pay credit cards in full each month during the grace period, the APR is effectively 0% regardless of the stated rate. For installment loans, the APR accurately reflects the cost of borrowing since you carry the balance until the loan is paid off. However, the total interest paid depends on the loan term. Longer terms mean more interest despite lower monthly payments.

Fees beyond interest significantly impact the true cost of credit. Credit cards may charge annual fees, balance transfer fees, cash advance fees, foreign transaction fees, and late payment fees. Installment loans often include origination fees, prepayment penalties in some cases, and late payment fees. When comparing credit options, consider all costs, not just interest rates. A loan with a slightly higher interest rate but no fees might cost less overall than a lower-rate loan with substantial upfront charges.

The Bottom Line

Understanding the different types of credit available and how each works empowers you to make informed borrowing decisions that support your financial goals. Revolving credit provides flexibility for ongoing needs and daily expenses, installment loans structure large purchases with predictable payments, and open credit encourages full payment each period. Each type has appropriate uses, advantages, and potential pitfalls. The key to using credit successfully is matching the credit type to your specific need, understanding the true cost of borrowing, and borrowing only what you can realistically repay. A balanced credit profile including both revolving and installment accounts, all managed responsibly, typically produces the strongest credit scores and positions you for financial success.

Frequently Asked Questions

Is it better to have revolving credit or installment loans?

The best credit type depends on your specific needs and circumstances. Neither revolving credit nor installment loans is inherently better—they serve different purposes. Revolving credit like credit cards works well for everyday purchases, earning rewards, and managing irregular expenses. Installment loans are better for large, one-time purchases like homes or vehicles where structured repayment over several years makes sense. The strongest credit profiles typically include both types, demonstrating your ability to manage different forms of credit responsibly.

How many credit cards should I have?

There is no magic number of credit cards that is right for everyone. The average American has three to four credit cards, but the optimal number for you depends on your financial habits and needs. Having at least two cards provides backup if one is lost or declined, and multiple cards can help keep utilization low on each individual card. However, more cards mean more accounts to monitor and more temptation to overspend. Focus on managing the cards you have responsibly rather than pursuing a specific number. If you struggle with credit card debt, fewer cards may be appropriate until you develop stronger money management habits.

Should I pay off installment loans early?

Paying off installment loans early can save you money on interest, but whether you should depends on several factors. Check if your loan has prepayment penalties, which some lenders charge if you pay off the loan before the scheduled term ends. Consider the loan’s interest rate compared to what you could earn by investing that money elsewhere. If your auto loan charges 4% interest but you could earn 8% in a retirement account, investing may make more financial sense than early payoff. High-interest loans like private student loans or personal loans with rates above 10% generally make good candidates for early payoff. Always maintain an emergency fund before aggressively paying down moderate-interest debt.

What is the difference between a credit card and a charge card?

Credit cards are revolving credit accounts that allow you to carry a balance from month to month, paying interest on the amount you do not pay off. They typically have preset spending limits and require minimum monthly payments. Charge cards are open credit accounts that require you to pay the full balance each billing period and typically have no preset spending limit. American Express is the primary issuer of consumer charge cards. While charge cards avoid interest charges since you cannot carry a balance, they often charge annual fees and may impose penalties if you cannot pay in full.

Can I convert revolving credit to installment credit?

You cannot directly convert a credit card balance into an installment loan within the same account, but you can effectively accomplish this through balance transfers or debt consolidation. Some credit card issuers offer programs that let you convert existing balances to fixed payment plans with set terms, essentially treating that portion of your balance like an installment loan. Alternatively, you can take out a personal installment loan to pay off credit card balances, consolidating revolving debt into structured installment payments. This can help if you find it difficult to pay down credit card balances with minimum payments but want the discipline of a fixed payment schedule.

How does secured credit differ from unsecured credit?

Secured credit requires you to pledge collateral that the lender can seize if you default on the debt. Mortgages secured by real estate and auto loans secured by vehicles are common examples. Secured credit cards, where you make a cash deposit that serves as your credit limit, help people build credit. Because collateral reduces lender risk, secured credit typically offers lower interest rates than unsecured credit. Unsecured credit has no collateral backing it, relying solely on your promise to repay. Most credit cards and personal loans are unsecured, which means lenders charge higher interest rates to compensate for the additional risk.

What happens to my credit score when I close a credit account?

Closing a credit account can affect your credit score in several ways. For revolving credit, closing a credit card reduces your total available credit, which can increase your overall credit utilization ratio and potentially lower your score. For example, if you have $10,000 in total credit limits and carry $3,000 in balances, your utilization is 30%. Closing a card with a $5,000 limit reduces your total available credit to $5,000, making your utilization 60%, which could significantly harm your score. Closing old accounts can also reduce your average credit age over time, though closed accounts continue to age and contribute to credit history length for up to 10 years. For installment loans, paying off and closing the account generally has minimal negative impact and may improve your score by reducing your overall debt burden.
