How much house can I afford? Here’s how to do the math.

Two-thirds of US adults own a home, a milestone that is still viewed as a key part of the American Dream. Yet, in 2024, buying a house often feels out of reach.

The median price for a new home has jumped to $495,750, according to the National Association of Home Builders, pricing out 77% of US households. Meanwhile, the Census Bureau found that the median household income is $80,610. Given that gap, how do millions of first-time homebuyers reach that dream every year?

Despite the rising costs, experts say affordable housing options still exist, depending on where you look and how you plan.

“The really obvious factor that affects housing affordability is the home price itself,” Danielle Hale, Realtor.com’s chief economist, said. “But there are two other factors that are really important for housing affordability. One is the mortgage rate. The other major factor is, of course, incomes. Those are the three legs of the housing affordability stool.”

Mortgage rates have risen sharply since the pandemic, exacerbating the affordability crisis.

“Home prices escalated out of control during the pandemic, and mortgage rates followed suit, climbing higher than what we were used to in the previous decade,” noted Logan Mohtashami, lead analyst at HousingWire.

There is some relief in sight with a Federal Reserve interest rate cut on the horizon, which indirectly results in lower mortgage rates. It can take several weeks for the full impact to be felt by prospective homebuyers, however, so buyers shouldn’t race into the market out of fear of missing out.

Home affordability is a deeply personal decision. Determining how much house you can actually afford starts with some basic details to help you figure out what your most important up-front and monthly costs should reasonably be.

How to calculate affordability: The key numbers to know

One of the best ways to figure out how much house you can afford is with a housing affordability calculator.

For starters, you should have the following information ready:

  • Gross household income: your annual pre-tax income

  • Debt: monthly payments on loans and credit cards

  • Down payment: the portion of the home’s purchase price paid up-front

  • Loan term: the duration of the loan (e.g., 15, 20, or 30 years)

  • Interest rates: the cost of borrowing, which changes based on your credit score and market trends

  • Mortgage insurance: insurance protecting the lender if the borrower defaults

  • Property taxes: This varies by location and is based on the home’s assessed value.

  • Closing costs: the expenses tied to the home loan, title, and other costs
