How it works
Fixed-rate loans are repaid in equal instalments (annuities): M = P × r ÷ (1 − (1 + r)^−n), where P is the amount borrowed, r the monthly rate (annual rate ÷ 12) and n the number of monthly payments.
Early payments are mostly interest; the principal share grows each month. The schedule groups payments by year.
Examples
- Car loan
- 15,000 at 6.5% over 5 years → 293.49 a month, 2,609.53 total interest.

Frequently asked questions
Does this include fees or insurance?
No. Lenders' APR includes some fees, so their total cost can be higher.
How can I pay less interest?
Borrow less, choose a shorter term or make extra repayments — see the Mortgage calculator's extra payment option.
