EMI (Equated Monthly Installment) is how almost every fixed-rate loan repayment is structured — home loans, car loans, personal loans, and most fixed-rate mortgages. The formula is identical across countries: a fixed monthly amount that pays a little more principal each month while the remaining balance shrinks. This calculator gives you all the numbers a typical lender's calculator does, plus a few extras.
You pick the principal, annual interest rate, tenure in years, and currency (seven supported with locale-aware formatting). The output is the monthly EMI, the total interest you'll pay over the loan's life, the total payment (principal + interest), and a complete amortization schedule with one row per month showing how much of each payment is principal versus interest and the remaining balance. The schedule is downloadable as CSV for spreadsheet analysis, and a pie chart visualizes the principal-vs-interest split — a useful way to see just how much of a long-term mortgage actually goes to interest.
How to use
- 1
Pick a currency
Choose USD, EUR, GBP, INR, AUD, CAD, or JPY. Formatting follows the locale (commas vs dots, position of the symbol).
- 2
Enter the principal
The loan amount you're borrowing.
- 3
Set the annual interest rate
Use the slider for annual percentage rate (APR). For most home loans this is between 5% and 12%.
- 4
Set the tenure
Use the slider for loan duration in years. Typical mortgages are 15–30 years; personal loans 1–5; car loans 3–7.
- 5
Review the breakdown
Monthly EMI, total interest, and total payment appear in three cards. A pie chart visualizes the principal vs interest split.
- 6
Export the schedule
Click CSV in the amortization table header to download the full monthly breakdown.

What formula does the calculator use?+
The standard reducing-balance EMI formula: EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ − 1), where P is principal, r is monthly rate (annual ÷ 12 ÷ 100), and n is total months. This matches what virtually every fixed-rate lender uses.
Will the numbers match my bank's calculator?+
They should match to within a few cents. Banks sometimes round slightly differently or include fees in the principal. The math itself is universal.
Why is so much of my early EMI going to interest?+
Because the interest is computed on the remaining balance, and that balance is largest at the start. The amortization schedule shows how the principal/interest split shifts over time — by the end, almost all of each payment is principal.
Can I compute prepayment scenarios?+
Not directly in this tool — the schedule assumes the full tenure with no prepayments. For prepayment modeling, export the CSV and modify the remaining balance manually.
Is my loan data uploaded anywhere?+
No. All calculations are done in your browser.
