How the Calculation Works (Simple Explanation)
This tool follows a widely used financial principle where lenders typically allow a borrower to spend around 36% of their income on debt obligations.
Step 1: Determine Affordable Payment
It calculates:
- 36% of monthly income
- Then subtracts existing debts
This gives your maximum affordable monthly loan payment.
Step 2: Estimate Loan Amount
Based on interest rate and loan duration, the calculator estimates how much total loan you can receive.
- Higher income = higher loan capacity
- Higher debts = lower borrowing power
- Higher interest = lower loan amount
- Longer term = higher loan amount
Example of Loan Affordability Calculation
Let’s understand with a real-life example:
Scenario:
- Monthly Income: $5,000
- Monthly Debts: $500
- Interest Rate: 6% annually
- Loan Term: 20 years
Step 1: Affordable Payment
36% of $5,000 = $1,800
Minus debts = $1,800 – $500 = $1,300 monthly payment
Step 2: Estimated Loan Amount
Based on 6% interest and 20-year term:
- Maximum Loan ≈ $180,000 – $200,000 (approx.)
What This Means:
You can comfortably manage a loan around $180K–$200K without overburdening your monthly budget.
