How it's calculated

Monthly housing budget M = min(income × front-end %, income × back-end % − debts), using gross monthly income.

The price P solves f × (P − down payment) + P × tax rate ÷ 12 + insurance ÷ 12 + HOA = M, where f is the monthly payment per dollar borrowed at your rate and term.

The Home Affordability Calculator is a simple tool designed to give an estimate of the home price you can afford based on your annual income, monthly debts, and available down payment. However, it’s a basic tool and doesn’t account for factors like tax rates, homeowners’ insurance, or credit score, so consulting a financial advisor or mortgage professional for a full assessment is advised.

Our Home Affordability Calculator is a (hopefully) useful tool designed to give prospective home buyers an estimate of how much they might be able to afford when purchasing a home. It calculates the estimate by considering the user’s annual income, monthly debts, and available down payment. The logic behind the calculator is based on standard financial advice: namely, that a homeowner should spend no more than 30% of their income (after paying off any debts) on housing costs. It also assumes a standard 4% interest rate on a mortgage to calculate the potential loan amount.

We must take a second to note some limitations. While this calculator can be a helpful starting point, it has several limitations. For instance, it doesn’t account for variations in local tax rates, homeowners’ insurance, potential HOA fees, or fluctuations in interest rates, all of which can significantly impact the total cost of home ownership. It also uses a simple estimate of housing cost as a percentage of income, which may not suit everyone’s financial circumstances. The calculator doesn’t take into account credit score, which can greatly affect the interest rate a borrower can secure, and therefore, the total amount of loan they can afford. It’s always recommended to seek advice from a financial advisor or a mortgage professional for a full understanding of how much you can afford when buying a home.

How to use our Home Affordability Calculator

Input Your Financial Details

Enter your annual income, monthly debts, and available down payment into the appropriate fields. Your annual income should be your total income before taxes, and your monthly debts should include any recurring payments such as student loans, credit card payments, car loans, etc. The down payment field should reflect the amount of money you have available to put down upfront on a home purchase.

Click “Calculate”

Click the “Calculate” button. The calculator will use the information provided to estimate the price of a home you might be able to afford. This is calculated based on the assumption that 30% of your monthly income (after subtracting debts) should go towards housing costs, and that you would get a mortgage with a 4% interest rate.

Review the Results

Frequently Asked Questions

›How much house can I afford?

Lenders typically cap your total housing payment at about 28% of gross monthly income and all debt payments at about 36%. The calculator finds the highest price whose full payment (principal, interest, taxes, insurance, HOA) fits within both limits.

›What is the 28/36 rule?

Spend no more than 28% of gross monthly income on housing and no more than 36% on housing plus other debts. On $120,000 a year ($10,000 a month) that is $2,800 for housing and $3,600 for all debts.

›How do my other debts affect affordability?

Every dollar of monthly debt payments reduces the back-end budget by a dollar. A $500 car payment can lower the home price you qualify for by about $70,000 at a 6.5% rate.

›Can I qualify with higher ratios?

Often, yes. FHA loans commonly allow 31% and 43%, and some programs go higher with strong credit or reserves. But a payment you qualify for isn’t always one you can comfortably afford.
