How It Works

Our calculator uses the same underwriting formulas that banks and lenders apply when reviewing mortgage applications. All calculations are based on standard amortization math, current Fannie Mae/Freddie Mac guidelines, and real market data from NAR, CFPB, and Freddie Mac.

Results are for educational purposes. Always consult a licensed mortgage professional before making financial decisions.

Frequently Asked Questions

Is this calculator free?

What data sources do you use?
Rate data from Freddie Mac PMMS. Tax averages from US Census Bureau. PMI estimates from Urban Institute. Lending criteria from Fannie Mae and FHA guidelines.

The part no calculator can tell you

Numbers like these tell you what you can afford. They cannot tell you whether a lender will say yes — and that varies more than almost anyone realises. In the complete 2025 federal record, approval rates across the 100 largest FHA lenders ran from 98.2% down to 21.3%. Same program, same year.

And it is not simply who applies where: holding state, loan amount, income, debt-to-income and loan-to-value constant, applicant mix explains only a 2.7× range in expected outcomes.
