Example Calculation
Let’s understand how the calculator works with a real-life example:
- Monthly Income: $5,000
- Monthly Expenses: $2,000
- Interest Rate: 6% annually
- Loan Term: 20 years
Step 1: Calculate Available Income
Available Income = Income − Expenses
= $5,000 − $2,000
= $3,000
This means you can potentially allocate $3,000 per month toward your mortgage.
Step 2: Estimate Loan Amount
Based on the interest rate and loan term, the calculator estimates the total loan you can afford.
In this example, the estimated loan amount would be approximately $418,000 (may vary slightly depending on exact calculations).
