What is a Loan Payment?

A loan payment is the amount you pay each month to repay a loan, such as a personal loan, auto loan, or mortgage. 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 standard formula for a fixed-rate loan payment is:

Monthly Payment = [P × r] / [1 - (1 + r)-n]
  • P = Loan amount (principal)
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Total number of payments (months)

This formula helps you understand how much you'll pay each month, including both principal and interest. It's widely used by banks and financial professionals.

Example: Loan Payment Calculation Step-by-Step

Let's say Alex wants to borrow $10,000 at a 6% annual interest rate for 5 years:

  • Loan amount: $10,000
  • Interest rate: 6%
  • Loan term: 5 years

First, convert the interest rate to a monthly rate: 6% ÷ 12 ÷ 100 = 0.005

Total payments: 5 × 12 = 60

Plug into the formula:

Monthly Payment = [10,000 × 0.005] / [1 - (1 + 0.005)-60] ≈ $193.33

Alex's estimated monthly payment is $193.33.
