How Much House Can You Afford?
A practical framework for thinking about housing costs without treating a calculator result as a loan approval.
A mortgage calculator can estimate a payment, but it cannot decide how much house you can actually afford. Your housing budget also depends on income, existing debts, taxes, insurance, maintenance, and your cash reserves.
Start with the complete housing cost
Principal and interest are only part of the monthly cost of owning a home. Depending on the property and loan, you may also have property taxes, homeowners insurance, mortgage insurance, HOA dues, and maintenance expenses.
Use the calculator as a scenario tool
Instead of entering one price and accepting the result, test several home prices, down payments, APRs, and terms. This shows how sensitive the payment is to each assumption.
Do not treat the result as approval
A calculator does not review your income, credit, assets, debts, or lender-specific underwriting rules. A lender may approve an amount that differs from your personal comfort level or from a calculator estimate.
Test your own amount, APR, down payment, and term.
