Mortgage calculator

See the mortgage payment, the wider housing cost, and what you may spend owning the house. Extra payments, nearby rates, and down-payment steps show which lever moves the outcome.

How this calculator works. The outlook amortizes month by month, then steps year by year. It separates P&I from housing cost, totals interest and ownership cash, and shows principal versus interest, the balance path, extra-payment time gained, rate sensitivity, down-payment steps, and cash to buy. Tax, insurance, and HOA can grow on their own rates. Life costs and an investment pile still sit beside the house.

Limitations. Educational projection only. It is not a pre-approval, a rate lock, or tax advice. Lenders use their own rules. Compare this outlook with a lender before you offer. Last reviewed September 2026.

This sits in Buying a Home

Home price, down payment, rate, term

The short path to a first result. Down payment is 20.0% of price — dollars and percent stay in sync.

▶Tax, insurance, HOA, PMI

These sit beside principal and interest. Growth rates are in Advanced assumptions.

▶Life around the house

Food, school, travel, extras, health, dependents, and other loans. Living costs inflate. Installment loans do not.

▶Income and the investment pile
▶Extra payments

Monthly, yearly, or one-time extra to principal. Results also have +$100 / +$250 / +$500.

▶Cash needed to buy

Down payment plus the estimates below. Change them; they are not a lender quote.

▶Advanced assumptions

Separate growth for tax, insurance, and HOA. Inflation still moves income, upkeep, and life.

▶Compare another loan

Same life costs and the same pile. Set compare term to 0 to hide it.
