Create Free AccountWhat it does
The Home Affordability Calculator determines the maximum purchase price you can qualify for based on your gross annual income, existing debts, available down payment, and targeted loan program (conventional, FHA, VA, USDA). Input income and debts to see the price ceiling where lenders will approve your mortgage.
Most buyers start price-shopping before understanding their actual affordability — this calculator prevents wishful thinking by anchoring maximum price to lender qualification formulas. Know your number upfront so you focus on realistic properties and negotiate from a position of pre-qualification strength.

Frequently asked questions
How much house can I afford?
Rule of thumb: 3–4x gross annual income. Calculator is more precise based on lender rules.
Does down payment percentage affect max purchase price?
Yes — larger down payment = smaller loan needed = lower monthly payment = ability to afford higher price.
Should I use my current rate or project future rates?
Use current market rates conservatively. If rates are low historically, model higher rates as well.
What if I want to maximize buying power?
Pay off debts, increase income, or save larger down payment. Even small debt payoff frees DTI capacity.
