Home affordability calculator: estimate payment pressure before shopping
A home can look affordable from a listing price and still strain the month after taxes, insurance, mortgage insurance, homeowners association dues, repairs, and closing cash are included. This local calculator keeps those assumptions visible and editable.

DTI context
Front-end and back-end debt-to-income ratios show payment pressure, not loan approval.
Cash needed
Down payment and closing-cost assumptions can matter as much as monthly payment.

Affordability is more than a loan payment
Principal and interest are only part of the monthly housing cost. Property taxes, homeowners insurance, mortgage insurance, HOA dues, utilities, maintenance, and repairs can change what the house feels like after move-in.
Use this estimate as a planning screen before making offers. A lender, underwriter, and the final property details can produce a different answer.
Debt-to-income is a pressure gauge
Debt-to-income compares monthly debt obligations with gross monthly income. The calculator shows housing-only and housing-plus-debt estimates so the payment does not get judged in isolation.
A lower ratio is not approval and a higher ratio is not an automatic denial. Loan type, credit, reserves, property, documentation, and lender rules still matter.
Cash reserves matter after closing
Closing with every available dollar can leave no cushion for moving, repairs, delayed reimbursements, utility deposits, or income disruption.
Before treating a price as affordable, compare estimated cash to close with the emergency fund and repair reserve that would remain afterward.
- Check whether taxes and insurance are escrowed or paid separately.
- Ask how mortgage insurance is calculated and when it may change or end.
- Leave room for inspection findings, rate changes, and appraisal outcomes.
FAQ
Does this calculator tell me what mortgage I qualify for?
No. It is an educational estimate. Qualification depends on lender underwriting, credit, income documentation, assets, property details, loan type, and current terms.
Why include PMI or MIP as an editable field?
Mortgage insurance can materially change the monthly payment, and the amount depends on loan type, down payment, credit, and program rules. Keeping it editable makes the assumption visible.
