Calculate Monthly Loan Payments, Interest & Amortization

Use this simple loan calculator to estimate your monthly payment, total interest, total repayment, and amortization schedule for fixed-rate installment loans. It can help with auto and car loans, personal loans, student loans, vehicle financing, boat and RV loans, home-equity scenarios, and many business or commercial loan estimates.

Compare Loan Costs

Change the interest rate or term to see how the monthly payment and lifetime interest change. A longer term can lower the scheduled payment while increasing the number of interest-bearing months.

Model Extra Payments

Add a one-time or recurring extra principal payment to estimate an earlier payoff date and potential interest savings. Actual lender rules for prepayment should always be checked in your loan agreement.

Interest-Only Scenarios

Switch to Interest Only to estimate periodic interest payments. Unless principal is separately repaid, an interest-only schedule can leave a balloon balance due at the end of the modeled term.

Download Your Schedule

Review the month-by-month principal, interest, and balance, then export the amortization schedule to CSV for Excel or Google Sheets.

This is a calculation tool, not a lender quote, approval decision, APR disclosure, or financial recommendation. Taxes, insurance, lender fees, origination charges, and program-specific rules are not automatically included.
