How the Mortgage Payment Affordability Calculator Works
The calculator works on a simple principle: it compares your monthly income against your monthly expenses to determine the amount available for mortgage payments. Then, using the annual interest rate and loan term, it calculates the maximum loan amount you can afford.
Here’s a step-by-step guide on how to use it effectively:
Step 1: Enter Your Monthly Income
Input your total monthly income from all sources. This includes salary, bonuses, rental income, or any other stable source of income. Make sure to use your net income after taxes for a realistic calculation.
Step 2: Input Monthly Expenses
Add all your recurring monthly expenses, such as utilities, groceries, insurance, loan repayments, and lifestyle costs. The calculator subtracts these expenses from your income to estimate the amount available for mortgage payments.
Step 3: Set the Annual Interest Rate
Enter the interest rate offered by your lender. Even a small change in interest rates can significantly affect your mortgage affordability, so use an accurate rate. For example, if your bank offers 5.5% annually, enter 5.5 in the field.
Step 4: Choose Your Loan Term
Decide on the loan term in years. Typical terms are 15, 20, or 30 years. A longer term usually reduces monthly payments but increases total interest paid over time.
Step 5: Calculate Your Mortgage
Click the Calculate button to see the results. The tool instantly shows:
- Affordable Monthly Payment: The amount you can comfortably pay each month without financial strain.
- Maximum Loan Amount: The total loan you can afford based on your income and expenses.
Step 6: Reset If Needed

Example Calculation
Let’s say your monthly income is $6,000, and your monthly expenses are $2,000. You plan to take a mortgage at an annual interest rate of 5% for 30 years.
- Monthly income: $6,000
- Monthly expenses: $2,000
- Available for mortgage: $6,000 – $2,000 = $4,000
- Annual interest rate: 5%
- Loan term: 30 years
After clicking Calculate, the calculator will show:
- Affordable Monthly Payment: $4,000
- Maximum Loan Amount: $750,000 (approximate)
This quick calculation helps you understand your borrowing capacity and plan your home purchase without exceeding your budget.
