Uses a fixed-rate amortizing payment model. Real loans may include fees, taxes, insurance, or changing rates.

How it works
For a fixed-rate amortizing loan, the periodic payment is: Pmt = L × r / (1 − (1 + r)^−n) where L is the loan amount, r is the periodic interest rate, and n is the total number of payments.
If the interest rate is 0%, the payment is simply the loan amount divided by the total number of payments.
Examples
- $25,000 loan at 6.5% for 5 years → estimate monthly payment and total interest
- Switch to weekly or biweekly frequency to compare payment sizes
- Try 0% interest to see equal principal-only repayment
