Calculate your monthly EMI, total payment and total interest for a home loan. Enter the loan amount, expected annual interest rate, and tenure to estimate your monthly obligation and total cost.

EMI Formula
Monthly EMI for a loan is calculated using the annuity (amortization) formula which converts the loan into equal monthly payments that include principal and interest.
Formula (mathematical):
EMI = P × r × (1 + r)n / ((1 + r)n − 1)
Where:
- P = Loan principal amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (tenure in years × 12)
- EMI = Equated Monthly Installment
The calculator computes the EMI using the formula above and then derives total payment (EMI × n) and total interest (total payment − P). It can also produce an amortization-style yearly snapshot showing outstanding principal at the end of each year.
Loan Snapshot
| Metric | What it Shows |
|---|---|
| Monthly EMI | The fixed monthly payment (principal + interest) |
| Total Payment | Total of all EMIs paid over the loan tenure |
| Total Interest | Amount of interest paid over the loan tenure |
This home loan calculator helps you estimate the monthly EMI, the total amount you'll pay over the loan tenure, and the total interest cost. Use it for quick planning when comparing home loan offers or deciding the loan tenure you can afford.
When to use this calculator
Use it before applying for a home loan to evaluate different interest rates and tenures, or to plan monthly budgets. Comparing EMIs across tenures and rates helps you decide on a sustainable repayment schedule.
How it works (plain explanation)
The calculator converts the entered annual interest rate into a monthly rate and applies the annuity formula to compute a fixed monthly EMI. Each EMI covers the monthly interest on the outstanding principal and a principal repayment portion. Over time the interest portion falls and the principal portion rises. The tool can also simulate month-by-month amortization internally to produce yearly outstanding principal snapshots for visualization.
Benefits of using this calculator
Quickly compare loan options and understand the long-term cost of borrowing. It helps you choose between higher EMIs with shorter tenures (lower total interest) and lower EMIs with longer tenures (higher total interest). Use conservative interest assumptions and consult lenders for exact quotes.
Factors that affect EMI & total cost
Key factors are loan amount, interest rate, and tenure. A small change in rate or tenure can significantly alter total interest. Prepayments and part-prepayments reduce outstanding principal and total interest but check lender rules for prepayment charges.
Frequently asked questions
How is EMI different from interest rate? EMI is the monthly payment amount; the interest rate determines how much of each EMI is interest versus principal.
Can I reduce tenure by paying more? Yes — making part-prepayments or increasing EMI reduces tenure and total interest; verify prepayment rules with your lender.
What happens if I miss an EMI? Missing EMI may attract penalties and affect credit history; contact your lender immediately to discuss options.
