The math behind yourmonthly payment
Every fixed-rate loan uses the same amortization formula. Here's how it works — and why understanding it saves borrowers thousands.
The formula
Monthly payment =P × r(1+r)ⁿ / ((1+r)ⁿ − 1), where P is principal, r is monthly rate (APR ÷ 12), and n is number of months.
Same math every US lender uses — no proprietary tricks.
Interest front-loaded
Early payments aremostly interest, not principal. On a 30-year mortgage, roughly 70% of month 1's payment is interest — 5% by month 300.
Why refinancing early can save you tens of thousands.
Term is a multiplier
Doubling your term does NOT double interest. It can 4×–5× it. A $30K loan at 10% for 5 years costs $8K interest — for 10 years, $17K.
Longer term = lower payment, higher total cost.
APR ≠ interest rate
APR includes fees(origination, points). A 7% interest rate can be a 9% APR after fees. Always compare APR, not just rate.
