Formula Used
The home affordability calculation follows these key formulas:
Maximum Mortgage Payment
Maximum mortgage payment = (Gross monthly income - Total monthly debt payments) × 28/100
This formula follows the 28/36 rule, where no more than 28% of your income should go toward housing costs and no more than 36% for all debt payments combined.
Maximum Home Price
Maximum home price = (Maximum mortgage payment × Loan term in months) / [(1 - Down payment percentage) × (1 - (Interest rate / 1200)) × (1 + (Interest rate / 1200))^Loan term in months - 1]
This formula calculates the maximum home price you can afford based on your mortgage payment, down payment, interest rate, and loan term.
The calculator uses these formulas to provide an accurate estimate of your home affordability based on your financial situation.
Worked Example
Let's walk through an example to see how the calculator works. Suppose you have:
- Gross monthly income: $5,000
- Total monthly debt payments: $800
- Desired down payment: 10%
- Loan term: 30 years
- Interest rate: 6.5%
Using the calculator with these inputs, you would get the following results:
Example Results
Maximum mortgage payment: $840
Maximum home price: $245,000
Monthly housing costs: $1,200 (including principal, interest, property taxes, and insurance)
This example shows that with a $5,000 monthly income and $800 in other debt payments, you could afford a home priced up to $245,000 with a 10% down payment and a 30-year mortgage at 6.5% interest.
Interpreting Results
Understanding the results from the home affordability calculator is key to making informed decisions about homeownership. Here's what each result means:
Maximum Mortgage Payment
This is the highest monthly mortgage payment you can comfortably afford based on your income and other debt obligations. It's calculated using the 28/36 rule, which recommends that housing costs shouldn't exceed 28% of your gross monthly income.
Maximum Home Price
The maximum home price you can afford is calculated based on your mortgage payment, down payment, interest rate, and loan term. This gives you an estimate of the highest-priced home you can realistically purchase with your current financial situation.
Monthly Housing Costs
This includes your mortgage payment, property taxes, homeowners insurance, and private mortgage insurance (PMI) if applicable. It gives you a complete picture of your total monthly housing expenses.
When interpreting these results, consider factors like:
- Your long-term financial goals
- Market conditions and home prices in your area
- Potential changes in your income or expenses
- Additional costs associated with homeownership
These factors can help you determine if the results align with your homeownership plans and whether you need to adjust your financial situation before purchasing a home.

How accurate is the home affordability calculator?
The home affordability calculator provides an estimate based on the information you provide. While it's a useful tool, actual affordability can vary based on your specific financial situation, market conditions, and other factors.
