How the Mortgage Calculation Works
This calculator uses standard affordability logic used in the mortgage industry.
1. Debt-to-Income Approach
It assumes approximately 36% of your monthly income can be used for total housing expenses.
Then it subtracts existing debts to calculate your available mortgage payment.
2. Loan Estimation Formula
Once the monthly payment is determined, the tool calculates loan size based on:
- Interest rate
- Loan duration
- Monthly affordability
This gives a realistic estimate of how much you can borrow from lenders.
Example of Mortgage Affordability Calculation
Let’s take a simple example:
User Inputs:
- Monthly Income: $6,000
- Monthly Debts: $500
- Interest Rate: 5%
- Loan Term: 30 years
Step 1: Calculate Affordable Payment
36% of income = $2,160
Minus debts = $2,160 − $500 = $1,660 monthly payment
Step 2: Estimate Loan Amount
Based on interest rate and term:
- Estimated Loan Amount ≈ $310,000 – $320,000
What This Means:
You can comfortably afford a home loan in this range without overstretching your budget.
