Loan Interest Calculator: How Much Interest Will I Pay My Lender?

To make major purchases (like homes or cars), most of us need to borrow money. While it’s possible to minimize the interest paid by maintaining a good credit score, shopping around for the lowest rates, and paying off your loan as quickly as possible, you probably can’t avoid paying interest altogether.

How Much You'll Pay in Loan Interest


If you borrow $20,000 at 5.00% for 5 years, your monthly payment will be $377.42 and you'll pay a total of $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).
