Loan & Mortgage Calculator

Simulate mortgage or car loan payments: compare amortizing, flat, and declining-balance interest, with a monthly schedule.

Amortizing, flat, or declining balance?

Flat interest is charged on the original principal for the whole term, so the rate looks small but the total interest is the largest. Amortizing loans (common for mortgages) keep the payment constant while the interest share shrinks, and declining-balance loans repay equal principal so payments fall every month. Enter the price, down payment, rate, and term to compare, then export the schedule to CSV.
