How the payment is calculated
A fixed-rate loan uses the amortization formula: monthly payment = P × r ÷ (1 − (1 + r)−n), where P is the amount borrowed, r is the monthly rate (APR ÷ 12), and n is the number of monthly payments. Early payments are mostly interest; the principal share grows every month. That’s why a 30-year mortgage costs so much more in total than a 15-year one at the same rate — you rent the money twice as long, and the balance falls more slowly.
Honest note: the rates on these pages are illustrative grids so you can see how the payment moves — they are not offers, and your real APR depends on your credit, the lender, and the market. Nothing here is financial advice.
