Loan Interest Calculator: How Much Interest Will I Pay?

Most of us need to borrow money to buy a car or home. While maintaining a good credit score, shopping around, and paying off your loan as quickly as possible can minimize interest rates, you probably can’t avoid paying interest altogether. To see how much interest you’ll pay over the lifetime of a fixed-rate loan, use our total interest calculator.

How Much I'll Pay in Loan Interest

If you borrow $20,000 at 5.00% for 5 years, your monthly payment will be $377.42. Your total interest will be $2,645.48 over the term of the loan.

Note: In most cases, your monthly loan payments won't change over time. With loan amortization, the proportion of “interest paid vs. principal repaid” changes each month. As the loan continues to amortize, the amount of monthly interest paid will decrease (while the amount of principal paid increases).
