Mortgage Affordability ToolUnited States Part of Cindrus (opens in a new tab)

Affordability by the ratio you set

Every field is blank on purpose. The price appears as soon as the required fields are filled.

Nothing is filled in for you, including the limits. You decide which ratios to test.

Before taxes and deductions. Add a co-borrower in the next field.

Optional.

Car loans, student loans, minimum credit card payments, child support and other loans. Leave out rent you will stop paying.

Cash you plan to put toward the purchase.

A rate from a quote, or one you want to test. Cindrus does not fill one in.

How long the loan would run.

A rate from the county or a listing in the area you are looking at.

A premium from an insurance quote.

Optional. Used only when the down payment is below 20 percent of the price.

Optional.

The share of income you want housing costs to stay within.

The share of income you want housing plus all other debts to stay within.

Estimated price at the limits you chose

The result is a calculation on your figures. It is not a guaranteed saving or an offer.

For illustrative purposes only. Not a loan offer or commitment to lend. Cindrus is not a lender, mortgage broker or loan originator, we pass no information to lenders, and no lender pays us.

This range is not a loan offer, a personal recommendation or an assessment of whether you would be approved for a loan.

This calculator does not assess your eligibility for a mortgage or represent a lender's affordability assessment.

Basis: your income, your debts, the limits you picked and the housing costs you typed. The rate and costs you can actually get may differ.

Behind the price range:
  • Monthly income is your yearly income divided by 12.
  • The rate is the one you entered and stays the same for the whole term.
  • Property tax and insurance grow with the price in the way you entered them.
  • Closing costs and cash reserves are not taken out of the down payment.

How the price range is worked out

First the calculator finds the most housing can cost each month: the lower of your housing limit times monthly income, and your total debt limit times monthly income minus the debts you pay now.

Then it searches for the price where principal and interest on the loan, plus tax, insurance, PMI and HOA dues, add up to that monthly figure. The loan is the price minus your down payment.

Federal rules do not set one maximum debt-to-income ratio. Under the CFPB's ability-to-repay rule, a lender has to consider debt-to-income or residual income, and loan programs publish their own limits. That is why the limits here are yours to choose.
