This is a rough planning estimate, not a pre-approval. Lenders apply their own debt-to-income limits, credit criteria, and stress-test buffers on top of this math.

The formula

Max payment

Income × max DTI% − existing debts

Max price

Max loan (from max payment) + down payment

This is a planning estimate, not a pre-approval — actual lenders apply their own underwriting rules, credit requirements, and rate-stress buffers that this simple formula does not model.

Debt-to-income (DTI) limits vary by lender and loan program; 36% is a commonly used planning figure, but qualifying DTI can run higher or lower depending on the loan type.
