Toolkit Feature

How much house can you actually afford?

The affordability calculator uses your income and debt-to-income ratio to estimate a realistic home price range before you start house hunting.

Start with a realistic number

Before touring homes or talking to a lender, it helps to know roughly what you can afford. The affordability calculator takes your income and existing debt obligations and estimates a home price and monthly payment range that fits sensible affordability guidelines.

How it works

  • Income input — enter your gross income to establish a baseline.
  • Debt-to-income ratio — factor in existing debt payments to see how much room is left for a mortgage.
  • Estimated price range — get a realistic home price range based on standard affordability thresholds.

Use it before you fall in love with a listing

Knowing your affordability range up front helps you avoid wasting time on homes outside your budget — and gives you a number to sanity-check against a lender's pre-approval later.

Who it's for

First-time buyers who aren't sure where to start, and current homeowners considering a move-up purchase who want an updated affordability estimate.

Frequently asked questions

How does it determine what I can afford?

It uses your income and existing debt to calculate a debt-to-income ratio, then estimates a home price and monthly payment range that fits within recommended affordability guidelines.

What is debt-to-income ratio, and why does it matter?

Debt-to-income ratio compares your monthly debt payments to your gross monthly income. Lenders use it to assess how much additional mortgage debt you can reasonably take on, so it directly affects what home price you can afford.

Is this a substitute for mortgage pre-approval?

No. It's a planning tool to help you estimate a realistic price range before you start house hunting or talk to a lender — actual pre-approval depends on your full financial profile and a lender's specific criteria.
