How it works

The math behind the result

The loan amount is the price minus the down payment. Its monthly principal and interest payment comes from the same amortization formula as any fixed-rate loan: the monthly rate applied to the balance, with the payment sized to reach zero at the end of the term.

The rest of the payment is not the loan. Property tax and homeowners insurance are yearly bills the lender usually collects monthly into escrow, so they are divided by 12. HOA dues are already monthly. Private mortgage insurance applies while the down payment is under 20% and is charged as a yearly share of the loan, spread over the months.

A shorter term raises the monthly payment and cuts the total interest sharply; at the same rate, a 15-year loan costs well under half the interest of a 30-year loan. The schedule under the chart shows how much of each year goes to interest.

P&I = L × r ÷ (1 − (1 + r)^−n)
monthly payment = P&I + tax ÷ 12 + insurance ÷ 12 + HOA + PMI
L = price − down payment · r = rate ÷ 12 · n = years × 12
