Home Affordability Calculator

Use Money Under 36’s home affordability calculator to find out how much home you can afford.

Your home is one of the largest purchases of your lifetime. The ensuing mortgage, taxes, and maintenance expenses will impact your finances for the next 15-30 years. It’s critical to choose a home you can afford. Our home affordability calculator will help you see if your target house fits your budget:

About Your Income, Expenses & Mortgage
  • Your gross monthly income before paying taxes, health insurance, etc.
  • The total of the minimum payments on any other debts you have (credit cards, car and student loans, mortgages on other properties).

How the home affordability calculator works

This calculator uses these guidelines for determining how much house you can afford, which are similar to common underwriting criteria that mortgage lenders use.

  • Your total mortgage payment should be no more than 28 percent of your gross monthly income
  • Your total debt payments (existing plus the new mortgage) should be no more than 40 percent of your gross monthly income.

This is a simple calculator and does not take into account factors that will increase your monthly housing payment — namely property taxes, homeowners insurance and, if you put down less than 20 percent of the home value, private mortgage insurance (PMI).

Just because you’re approved doesn’t mean you can afford it

Because we didn’t include taxes and insurance, the calculator is conservative enough so that you could likely still be approved for a mortgage at this level after adding them in. That’s our goal: To give you a sense of the maximum home price and mortgage payment for which you might reasonably be approved with good credit.

Realistically, however, you should aim to keep the ratio of your mortgage payment as low as possible. The more money you aren’t spending on your home, the more money you have to save. This won’t be possible in all real estate markets, and it’s possible — if you live in Northern California or New York City, for example — that you may have to spend more than this calculator suggests to be able to buy at all.

Next steps

If you’re beginning to consider buying a home, make sure you’re up to date on your credit report and score and then consider getting mortgage pre-approval, which can give you the financial confidence to be able to make a strong offer on the right house when you see it. Pre-approval is free and no-obligation, but lets you know whether you would likely qualify for the amount and interest rate you want.
