Loan Payment Calculator

Results are estimates for fixed-rate loans. Your lender’s offer may include fees that change the real cost.

Our free loan payment calculator helps you estimate your monthly payments, total interest, and full repayment amount instantly. Whether you are taking out a personal loan, auto loan, or mortgage, using a loan payment calculator allows you to plan your budget with precision before signing any agreement.

How this loan payment calculator works

Enter how much you want to borrow, the yearly interest rate, and how many years you will take to repay. This loan payment calculator instantly shows your estimated monthly payment, the total interest you will pay over the life of the loan, and the overall amount you will have paid back.

The formula behind the loan payment calculator

Most personal loans, car loans, and mortgages use the same fixed-payment formula. Your monthly payment equals the loan amount multiplied by the monthly interest rate, divided by one minus (1 + monthly rate) raised to the power of negative total payments. The monthly rate is your annual rate divided by 12, and the total number of payments is the term in years multiplied by 12.

Loan calculation example

Suppose you borrow 20,000 at 6% annual interest for 5 years. The monthly rate is 0.5% and there are 60 monthly payments. By running these numbers through our loan payment calculator, the monthly payment comes out to about 386.66. Over 5 years, you pay about 23,200 in total, of which about 3,200 is interest.

Key factors that affect your monthly loan payment

Understanding what determines your monthly payment can help you save thousands of dollars over time:

• Loan Amount (Principal): The total amount you borrow directly impacts both your monthly payment and total interest.
• Interest Rate: Even a 1% reduction in interest rate drastically lowers your monthly obligation and cumulative cost.
• Loan Term: Shorter terms increase monthly payments but heavily reduce the total interest paid. Longer terms offer lower monthly bills but cost more in the long run.

Ways to lower what you pay

• Choose a shorter term: Payments are higher, but you pay much less interest overall.
• Make a bigger down payment: A smaller principal means less interest over time.
• Compare lender offers: Shop around for the best rates using a loan payment calculator to compare different terms.
• Pay extra when possible: Additional principal payments reduce your balance faster if your lender has no prepayment penalty.

Frequently asked questions

Does a longer loan term save money?

It lowers your monthly payment, but you pay interest for more months, so the total cost goes up. Try changing the term above in our loan payment calculator to see the difference.

What is the difference between interest rate and APR?

The interest rate is the base cost of borrowing the money. The APR includes both the interest rate and additional lender fees, making it a better metric for comparison. You can learn more about loan amortization principles on Wikipedia.

Using an accurate loan payment calculator helps you compare borrowing options and make well-informed financial decisions before committing to any loan agreement.

Can I pay off a loan early?

In most cases yes, and doing so saves you interest. Always check your loan agreement to ensure there are no prepayment penalties.
