Loan Payment Calculator
Estimate payment amount, total interest, overall cost and extra-payment savings on a fixed-rate loan.
Use this loan payment calculator to estimate the regular payment on a fixed-rate loan and see how much the total cost comes from interest. It works well for personal loans, installment financing, refinancing comparisons and quick affordability checks before you commit.
Enter the loan amount, annual rate, term and payment frequency to view the base payment, total interest and total paid over the full schedule. You can also add an extra payment per period to see how much time and interest you may save by paying the balance down faster.
This is an educational estimate that assumes a fixed rate across the whole term. Real contracts may include fees, taxes, insurance, grace periods, penalty rules or lender-specific amortization details that change the final numbers.
Use clear inputs to get a more useful result.
