Installment Credit is a type of credit arrangement for which there are regular, periodic payments of a specified amount over a predetermined period. These payments typically include both the principal (the original sum borrowed) and interest (the cost of borrowing the funds). By the end of the term, the entire loan amount, including interest, should be fully paid off.
Definition and Key Features
Installment Credit entails borrowing a lump sum and agreeing to repay it over regular intervals, often monthly. Some of the defining features of installment credit include:
- Regular Payments: Payments are made on a set schedule, such as monthly.
- Equal Payment Amounts: Each installment generally includes the same principal and interest amounts.
- Fixed Term: The loan has a predetermined end date by which the borrower is expected to have repaid the entire amount.
- Amortization: Payments typically amortize the loan, meaning part of the monthly payment reduces the principal balance, and part covers interest costs.
Types of Installment Credit
- Auto Loans: Used to purchase vehicles, where the borrowed amount is repaid over a set period, typically 3-7 years.
- Mortgages: Long-term loans used to buy real estate, often repaid over 15-30 years.
- Personal Loans: Unsecured loans taken for various purposes such as debt consolidation or major expenses, typically repaid over 1-5 years.
- Student Loans: Loans designed to help students pay for post-secondary education, usually repaid over multiple years after graduation.
Formula and Calculation
Installment loans are usually calculated using the amortization formula:
Where:
- \( PMT \) = Periodic payment amount
- \( P \) = Principal loan amount
- \( r \) = Periodic interest rate (annual rate divided by the number of periods per year)
- \( n \) = Total number of payments
Examples
- Auto Loan: If you take a $20,000 auto loan with an interest rate of 5% per annum for 5 years, your monthly installment payment can be calculated using the amortization formula.
- Mortgage: For a $300,000 mortgage with a 30-year term at an interest rate of 4% per annum, monthly installments would also be determined using the same formula.
Historical Context
Installment credit has been a significant part of consumer finance since the early 20th century, particularly with the rise of consumerism and the availability of mass-produced goods such as cars and household appliances. The practice allowed individuals to purchase expensive items and pay for them over time, making such items more accessible.
Applicability and Advantages
- Budgeting: Predictable, regular payments make household budgeting easier.
- Building Credit: Regular, on-time payments can help improve a borrower’s credit score.
- Access to Goods: Allows immediate access to essential items like cars and homes without needing the entire purchase price upfront.
Comparisons
- Revolving Credit vs. Installment Credit: Unlike revolving credit (e.g., credit cards), installment credit has a fixed number of payments and an end date.
- Secured vs. Unsecured: Installment loans can be secured (backed by collateral like a car or house) or unsecured (based on the borrower’s creditworthiness).
Related Terms
- Principal: The amount of money borrowed or remaining unpaid on a loan.
- Interest: The cost of borrowing money, generally expressed as an annual percentage rate (APR).
- Amortization: The process of paying off a debt over time through regular payments of principal and interest.
FAQs

A: Missing a payment can result in late fees, increased interest rates, and negative impacts on your credit score.
Q: Can I pay off an installment loan early?
A: Most lenders allow early repayment, though some may charge a prepayment penalty.
