• Helps in planning home purchases within financial limits.
• Speeds up the loan application process by pre-qualifying borrowers.

How Does a Home Loan Eligibility Calculator Work?

The calculator uses your inputs to assess your repayment capacity and match it against lending criteria. It primarily calculates your Equated Monthly Installment (EMI) affordability and then derives the maximum loan amount you can service comfortably.

Key Inputs

• Monthly Income (basic + allowances)
• Monthly Expenses (living costs, EMIs, etc.)
• Existing Debt Obligations
• Interest Rate (annual)
• Loan Tenure (in years or months)

The Formula Behind Home Loan Eligibility

The eligibility calculation is based on the EMI formula which determines the loan amount that can be serviced given a fixed EMI amount, interest rate, and tenure.

EMI Formula

$$\text{EMI} = P \times \frac{r \times (1+r)^n}{(1+r)^n - 1}$$

Where:

• $P$ = Principal loan amount
• $r$ = Monthly interest rate (annual rate divided by 12 and converted to decimal)
• $n$ = Number of monthly installments (loan tenure in months)

Rearranged to find Principal (Loan Amount)

$$P = \frac{\text{EMI} \times ((1+r)^n - 1)}{r \times (1+r)^n}$$

Steps to Calculate Eligibility

1. Calculate your affordable EMI using your net income after expenses.
2. Plug the EMI, interest rate, and tenure into the formula to find the maximum loan amount.
