Affordability Calculators: How Much Can You Afford?

Wondering how much house you can afford? Learn how affordability calculators work and how to use them to set a smart home buying budget.
Introduction

One of the first questions homebuyers ask is: How much house can I afford? An affordability calculator gives you a quick estimate based on your income, debts, and savings. Let’s look at how these calculators work and how to use them to set a smart budget.

How Affordability Calculators Work

Most calculators factor in:

  • Income: Your monthly earnings. Your earnings, along with credit score tips, influence what lenders offer.
  • Debts: Credit cards, student loans, car payments, and other obligations.
  • Down Payment: Larger down payments lower monthly costs. Pairing a calculator with down payment options makes results more accurate.
  • Interest Rates: Rates depend on your credit score and market conditions.

The 28/36 Rule

Lenders often use the 28/36 rule:

  • No more than 28% of gross income on housing.
  • No more than 36% of income on total debts.

Example Calculation

If you earn $6,000/month and have $500 in debt:

  • Max housing = $1,680 (28%).
  • Max debt = $2,160 (36%).
    This means your total housing and debt combined should not exceed $2,160.

Why Pre-Approval Still Matters

Calculators are great for estimates, but lenders use stricter qualifications. Use this alongside our loan pre-approval checklist to confirm results.
