What is a Loan Payment?
A loan payment is the amount you pay each month to repay a loan, such as a mortgage, auto loan, or personal loan. It typically includes both the principal (the amount you borrowed) and the interest (the lender's charge for lending you money). Loan payments are a key part of personal finance and are used by banks, lenders, and borrowers to manage and track debt. Understanding your loan payment helps you budget, compare loan options, and plan for the future.

How is a Loan Payment Calculated? (Formula Explained)
The calculator supports both fixed term and fixed payment calculations:
Number of Payments = log(Payment / (Payment - P × r)) / log(1 + r)
- P: Loan amount (principal)
- r: Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n: Total number of payments (months)
- Payment: Fixed monthly payment
These formulas help you understand how much you'll pay each month, how long it will take to pay off your loan, and the total interest paid. They're widely used by banks and financial professionals.
Example: Loan Payment Calculation Step-by-Step
Let's say Alex borrows $10,000 at a 5% annual interest rate for 5 years:
- Loan amount: $10,000
- Interest rate: 5%
- Loan term: 5 years
Monthly rate: 5% ÷ 12 ÷ 100 = 0.0041667
Total payments: 5 × 12 = 60
Monthly Payment = [10,000 × 0.0041667] / [1 - (1 + 0.0041667)-60] ≈ $188.71
Alex's estimated monthly payment is $188.71. Total paid: $11,322.60. Total interest: $1,322.60.
