Mortgage Calculator
Monthly payments, interest and totals for a home loan.
Equal payments: M = P·r(1+r)ⁿ ÷ ((1+r)ⁿ − 1) · Equal principal: first payment P/n + P·r, total interest P·(n+1)·r/2.
- Equal payments or equal principal — which is better?
- Equal payments (amortized) keep the monthly amount constant but accrue more total interest. Equal principal starts higher and declines, saving interest over the term.
- Does this include taxes and insurance?
- No — it covers loan principal and interest only. Real monthly costs often also include property tax and home insurance.
- What if my rate is adjustable?
- This calculator assumes a fixed rate for the full term. For adjustable loans, recompute with the current rate to see where payments stand.
