Home Affordability Calculator

Make buying your new home easier by getting an estimate of your price range. Our free home affordability calculator will do the math for you, that way you can house hunt for something that fits perfectly into your budget.

Let’s get started!


If you’re ready to buy a home, you need to know what your price range is. Our Home Affordability Calculator helps you determine the price of a home that fits perfectly in your budget.


Enter any number here. Some programs allow down payments as low as 3%. Just remember, the more you put down, the less your monthly payment will be.


Your gross income amount is how much money you earn annually before taxes are deducted.


This includes monthly minimum credit card payments, car and student loan payments, child support, etc. Do not include cost of living expenses.


Choose the length of the loan term you plan to use.

Debt-to-income ratio is calculated by taking all of your monthly costs (including the monthly mortgage payment) and dividing it by your monthly gross income.

For example, a Conventional fixed rate loan with the terms purchase price of $312,500, on a loan term of 360 months, down payment of 20%, and an interest rate of 6.5%, will result in an annual percentage rate of 6.598% with $3,613 in APR fees.

Knowing how much home you can afford is the first step to making your homebuying process easier. By using a home affordability calculator, you can get an idea of how a mortgage could work within your budget.

Things that impact how much mortgage you can afford include:

  • Down payment — What you pay up front on a mortgage to get a lower interest rate or monthly payment.
  • Gross annual income — Your gross annual income is what you make before taxes. Ideally, borrowers should aim to spend 28% or less of their gross annual income on a mortgage.
  • Monthly debt — Monthly debts impact how much of a mortgage you can afford and may include credit cards, student loans, and child support, to name a few.
  • Mortgage rate — Mortgage rate is the amount of interest you will pay on the principal of your mortgage and can raise your monthly payment depending on your mortgage type.
  • Loan term — Your loan term determines the length or “life” of your mortgage. Popular loan terms include 30- and 15-year mortgages.
  • Debt-to-income-ratio (DTI) — The percentage of your monthly income that goes toward your monthly debt.

Part of calculating mortgage affordability includes knowing your debt-to-income ratio or DTI. Your DTI is determined by your total monthly debt compared to your gross monthly income. Typical contributing factors to your DTI could include rent, student or auto loans, and credit card payments. Let’s look at an example together.

Say your monthly income is $4,000 and your monthly debts total $1,200. First, divide $1,200 by $4,000 for 0.3 as a result. Next, multiply 0.3 by 100 to find what your percentage will be. In this case, your DTI equals 30%. Ideally, most lenders look for a DTI of 43% or lower. The lower your DTI, the more mortgage benefits and programs you may qualify for.
