How to Calculate Your Monthly Loan Payments

Understand the math behind loan payments and learn how to calculate your monthly costs before applying for a personal loan.

Read the complete article below for general educational information about personal finance and borrowing. Loan terms, eligibility, and approval decisions are determined by individual lenders.

Understanding how loan payments are calculated helps you make informed borrowing decisions. Here's a guide to calculating your monthly loan payments.

The Loan Payment Formula

Monthly Payment = P * [r(1+r)^n] / [(1+r)^n-1]

Where: - P = Principal (loan amount) - r = Monthly interest rate (annual rate / 12) - n = Number of payments (loan term in months)

Example Calculation

For a $10,000 loan at 10% APR over 36 months: - P = $10,000 - r = 0.10 / 12 = 0.00833 - n = 36

Monthly Payment = $322.67

Factors Affecting Your Payment

Loan Amount

Interest Rate

Loan Term

Using a Loan Calculator

Most lenders offer online calculators. Enter your loan amount, interest rate, and term to see your estimated monthly payment.

Total Cost of the Loan

Don't just look at monthly payments. Calculate the total amount you'll pay over the life of the loan:

Total Cost = Monthly Payment x Number of Payments

For our example: $322.67 x 36 = $11,616.12

This means you'll pay $1,616.12 in interest on a $10,000 loan.
