Your numbers

Adjust the assumptions below. Results are estimates in USD.

This estimate assumes a 30-year loan. DTI is the share of gross monthly income used for debt payments; the engine limits this assumption to 1–65%.

How this works: this estimates a payment range using a debt-to-income assumption, then converts available principal & interest into an estimated loan amount.

This is an estimate only and not a loan approval or commitment to lend.

How affordability is estimated

Enter annual income, monthly debts, down payment, interest rate, and estimated taxes/insurance/HOA.

The calculator uses a debt-to-income assumption to estimate available monthly housing payment.

Actual affordability depends on credit profile, loan program, reserves, property details, and current underwriting guidelines.

Frequently asked questions

What DTI should I use?

Many programs use different DTI limits. 43% is a common planning assumption, but actual approvals can be lower or higher depending on the file.

Does affordability equal approval?

No. It is only a planning estimate. Full pre-approval requires documentation and underwriting review.

Can I afford more with a larger down payment?

Often yes, because a larger down payment may reduce loan amount and monthly payment, but cash reserves and program rules also matter.
