Installment Calculator
Calculate your monthly loan installment and view a full amortization schedule. Enter your loan details and choose between two interest methods:
- Flat Rate: interest is calculated on the original principal for the entire loan term. Simpler to calculate, but results in a higher effective rate.
- Reducing Balance: interest is calculated on the remaining balance each month (standard amortization). Your interest cost decreases as you repay.
All calculations are performed entirely in your browser — no data is sent to any server.
