Guide
The home affordability calculator estimates the home price your income may support under a housing payment ratio. It starts with monthly income, subtracts monthly debt, and uses the remaining housing capacity to estimate a purchase price.
It includes down payment, mortgage rate, term, property tax rate, and insurance rate. This makes it more realistic than multiplying annual income by a simple rule of thumb.
Enter annual income, current monthly debt, down payment, loan term, mortgage rate, tax rate, insurance rate, and your target housing ratio. The calculator estimates maximum housing payment and backs into an affordable home price.
Use the result as a planning range, then compare it with lender preapproval and your own comfort level. A lender may approve more than you personally want to spend every month.
The calculator estimates maximum housing payment as monthly income multiplied by the housing ratio minus monthly debt. It then solves for the home price using mortgage payment math plus monthly tax and insurance assumptions.
The result is sensitive to rate and tax assumptions. A small rate increase can reduce buying power because more of the payment capacity goes to interest.
Use this page before touring homes, before changing down payment targets, or when mortgage rates move. It helps create a realistic search range before emotional property comparisons begin.
Affordability is not the same as approval. Credit score, reserves, loan type, income stability, local taxes, HOA dues, and lender overlays can all affect real approval amounts.
Housing ratio
The share of gross monthly income used for housing costs.
Debt-to-income
A comparison of monthly debt obligations to monthly income.
Buying power
The estimated home price supported by payment capacity and down payment.
No. It is a planning estimate. A lender preapproval reviews credit, income, assets, debt, and loan program rules.
Existing debt uses part of monthly income, leaving less room for housing payment under common debt-to-income guidelines.
Not always. Leave room for maintenance, utilities, savings, and lifestyle costs before choosing a final budget.
