Buying a home requires more than just savings for a down payment—it also depends on whether you are eligible for a mortgage loan. Lenders evaluate eligibility using your income, monthly expenses, existing debts, credit profile, and other financial factors.
Our Mortgage Loan Eligibility Calculator makes this process simple. By inputting your monthly income, expenses, debts, interest rate, and loan term, you get an instant estimate of your eligible monthly mortgage payment and maximum loan amount.
This tool helps you understand whether you are financially ready to take on a mortgage and how much you can borrow before approaching a lender.
Formula Behind the Calculator
The calculator uses two primary formulas:
1. Debt-to-Income Ratio (DTI) Method
Maximum Allowable Debt = Monthly Income × 36%
This follows the common “36% rule” which says your total debts (including mortgage, car loans, student loans, etc.) should not exceed 36% of your gross monthly income.
2. Eligibility for Mortgage Payment
Available for Mortgage = Maximum Allowable Debt − Monthly Expenses − Existing Loan Payments
3. Maximum Eligible Loan Amount
Loan Amount = Affordable Payment × (1 − (1 + r)^−n) ÷ r
Where:
- r = monthly interest rate (annual ÷ 12)
- n = total payments (loan term × 12 months)
How to Use the Calculator
- Enter your monthly income (before taxes).
- Input your monthly expenses (utilities, groceries, etc.).
- Add your existing loan payments (car, student loan, credit cards).
- Enter the annual interest rate offered by banks.
- Choose a loan term in years (commonly 15, 20, or 30 years).
- Press Calculate.
- The result will show:
- Eligible Monthly Mortgage Payment
- Maximum Mortgage Loan Amount
Example
Let’s say you earn $7,000 per month, with $1,500 in expenses and $800 in existing debts. You want a loan at 5% annual interest for 30 years.
Step 1: Maximum allowable debt = 7000 × 0.36 = $2,520.
Step 2: Available for mortgage = 2520 − 1500 − 800 = $220.
Step 3: Monthly interest rate = 5% ÷ 12 = 0.004167.
Step 4: Loan term = 30 × 12 = 360 months.
Step 5: Loan amount = 220 × (1 − (1.004167)^−360) ÷ 0.004167 ≈ $41,000.
This means you may be eligible for a mortgage loan around $41,000, with an affordable monthly payment of about $220.

5. What is the difference between affordability and eligibility?
Affordability is how much you can pay; eligibility is how much banks are willing to lend.
6. Can I get a higher loan with a longer term?
Yes, a longer term reduces monthly payments, increasing eligibility, but costs more interest overall.

No, lending rules vary by country, lender, and government policies.

13. What if my expenses are very high?
High expenses reduce the income available for mortgage, lowering eligibility.

15. Do lenders always use 36% as a fixed number?
Not always. Some may allow 40–43% for strong applicants.
16. What is a pre-qualification vs pre-approval?
Pre-qualification is a rough estimate; pre-approval is a lender’s conditional commitment.
17. Will a large down payment improve eligibility?
Yes, it lowers the loan amount you need to borrow, making you more eligible.
