Loan Calculator
Estimate your monthly payment, total interest and total repayment for any fixed-rate personal, auto or student loan.
How to Calculate a Loan Payment
A loan calculator shows what you will pay each month and how much interest you will pay over the life of a loan. Whether you are comparing a personal loan calculator result with a bank quote, planning a debt consolidation loan or checking the monthly payment on a $10,000 personal loan, the math is the same. Enter the amount you want to borrow, the annual interest rate (APR) and the term in years to see your estimate instantly.
The Loan Payment Formula
Most installment loans in the United States use a fixed-rate amortization formula: payment = P x r / (1 - (1 + r)^-n). P is the loan amount, r is the monthly interest rate (APR divided by 12) and n is the total number of monthly payments. For example, a $25,000 loan at 8% for 5 years has a monthly payment of about $507, with roughly $5,400 in total interest.
What Affects Your Monthly Loan Payment?
- Loan amount: borrowing more raises both the payment and the total interest.
- Interest rate: your credit score, income and debt-to-income ratio drive the APR you are offered.
- Loan term: longer terms lower the monthly payment but increase total interest.
- Fees: origination fees of 1% to 8% raise your true cost, so compare APRs, not just rates.
Personal Loans vs. Other Loans
Personal loans are usually unsecured, with fixed rates and terms between one and seven years. Auto loans and mortgages are secured by the vehicle or home, which often means lower rates. Use this calculator for any fixed-rate installment loan, including student loans, home improvement loans and medical financing.
Tips to Lower Your Loan Cost
Improve your credit score before applying, compare offers from banks, credit unions and online lenders, choose the shortest term you can comfortably afford, and make extra payments toward principal when possible. Always check for prepayment penalties first. If you are consolidating credit card debt, make sure the new rate is lower than your current average rate, otherwise you may pay more overall.
