How This Calculator Works
The tool follows a practical financial rule:
👉 Only 30% of your remaining income (after expenses) should go toward loan payments.
Calculation Process:
- Available income = Income – Expenses
- Affordable payment = 30% of available income
- Loan amount is calculated using interest rate and loan duration
This ensures that your loan remains manageable and does not strain your finances.
Example Calculation
Let’s understand with a simple example:
Input:
- Monthly Income: $3,000
- Monthly Expenses: $1,500
- Interest Rate: 6%
- Loan Term: 20 years
Calculation:
- Available Income = $3,000 – $1,500 = $1,500
- Affordable Payment = 30% of $1,500 = $450
Based on this:
- Monthly Payment: $450
- Estimated Loan Amount: ~$62,000 (approx.)
This gives you a clear idea of your borrowing capacity.
Tips to Improve Your Loan Affordability
If your loan amount is lower than expected, here are ways to improve it:
1. Reduce Monthly Expenses
Cut unnecessary spending to increase available income.
2. Increase Income
Consider side income or salary growth.
