How much home can you realistically afford?

This home affordability calculator turns your income, monthly debt, down payment, interest rate, property taxes, homeowners insurance, and optional HOA dues into two clear planning views: a Comfort Target built around the monthly housing payment you choose, and a separate Qualification-Style Range for context.

Buying a home involves more than finding the highest number a calculator will produce. Prosperity helps you explore a range that feels comfortable to you, compare it with a separate higher planning reference, and understand what is shaping both results.

WHAT YOU CAN EXPLORE

- Your estimated Comfort Target home-price range
- A separate Qualification-Style planning range
- Estimated monthly housing payment
- Estimated loan amount and down payment
- Principal and interest, property tax, homeowners insurance, PMI, and HOA components
- Comfort and total debt-to-income ratios
- The gap between the two planning ranges
- Approximate debt impact and the factor limiting the higher range
- A plain-language Prosperity insight and next consideration

HOW IT WORKS

1. Enter your household income, monthly debt, interest rate, down payment, and estimated home costs.
2. Set your Comfort Target as a percentage of income or a monthly dollar amount.
3. Review your buying range, monthly payment, payment breakdown, affordability drivers, and insight.

Change any blue input to explore another scenario. The workbook recalculates automatically.

IMPORTANT PLANNING LIMITATIONS

This calculator is for personal education and planning only. Results are estimates based on the information and assumptions you enter. It is not a mortgage approval, preapproval, loan offer, guarantee of qualification, or financial, tax, legal, or lending advice.

Actual lender requirements, mortgage rates, property taxes, insurance, mortgage insurance, fees, and other costs may differ. Lenders may consider credit history, income documentation, reserves, loan-program requirements, and other factors not modeled here.

This version does not calculate closing costs or cash to close, utilities, maintenance or repairs, loan-program eligibility, credit scoring, amortization schedules, extra-payment strategies, rent-versus-buy outcomes, or lender approval.

If you are making a home-buying or borrowing decision, confirm current numbers and requirements with appropriately qualified professionals.
