Mortgage Affordability Calculator
Estimate an affordable home price before comparing down payment, PMI, and refinance math.
Comparison
Affordability vs preapproval
Preapproval can show what a lender may allow. Affordability should also consider cash reserves, existing debt, maintenance, and whether the payment blocks savings goals.

Execution tools
Recommended Tools to Help You Take Action
These neutral examples fit the mortgage action suggested by the calculator. Compare APR, lender fees, closing costs, PMI assumptions, and break-even timing before choosing a path.
If the payment looks affordable, compare lender estimates from options such as Rocket Mortgage, LendingTree, or SoFi Mortgage.
If the result points to payment stress or future savings, compare refinance options through platforms such as Credible or LendingTree refinance.
If PMI or income burden is the issue, use affordability and PMI tools to test down payment changes, LTV, and monthly payment risk before contacting a lender.
