How much house can I afford?
Start with the payment you can comfortably support, then work backward to a home price. A mortgage payment calculator can estimate principal and interest, but true affordability also depends on taxes, insurance, HOA fees, debts, income stability, savings and lender rules.
Run the scenario.
The calculator is prefilled with the example above. Change any input and the result updates immediately in your browser.
- A home price alone does not tell you whether the payment fits your budget.
- Principal and interest are only part of the monthly housing cost.
- A larger down payment reduces the amount financed but uses more cash up front.
- Interest rate changes can materially change the payment even when the home price stays the same.
Start with the monthly payment
A useful first step is to choose a monthly housing amount that fits alongside your other obligations and savings goals. Then test different home prices, down payments and rates until the principal-and-interest payment is in that range.
NumLuma intentionally does not label one debt-to-income ratio as universally correct. Lenders, households and local housing costs differ, so treat the calculation as a planning input rather than an approval estimate.
Add the costs the mortgage formula does not include
Property taxes, homeowners insurance, mortgage insurance, HOA dues, maintenance and closing costs can all change the real cost of owning the home. The calculator below focuses on fixed-rate principal and interest so you can see that part clearly.
Before deciding what is affordable, add the costs that apply to the property and keep an emergency buffer instead of using the maximum payment a lender might allow.
Quick questions.
Does this calculator tell me the maximum mortgage I can qualify for?
No. It estimates principal-and-interest payments. Qualification depends on lender rules, income, debts, credit, property details and other factors.
Does the payment include property tax or insurance?
No. Those costs should be added separately when judging the full monthly housing cost.
