Compare loan tenures without confusing EMI and total cost
A reproducible 100,000-unit loan example explains monthly payments, total interest, rounding, and the assumptions behind the EMI calculator.

Open EMI CalculatorStart with the same loan and rate
Enter a principal of 100,000 and an annual rate of 8 in the EMI Calculator. Compare a tenure of 10 years with 20 years. These are hypothetical inputs, not a lender offer. Use one currency consistently; changing the displayed currency symbol does not convert money.
This example assumes a fixed nominal annual rate, monthly interest equal to the annual rate divided by 12, and payments at the end of each month. It excludes fees, insurance, taxes, rate changes, and extra repayments.
Read all three results
The longer tenure reduces the monthly payment by about 376.85 units but increases total interest by about 55,152.51 units. A smaller installment does not imply a cheaper loan.
Total repayment includes the original 100,000 principal. Total interest is the repayment above that principal. Confusing the two produces misleading comparisons.
| Tenure | Monthly EMI | Total repayment | Total interest |
|---|---|---|---|
| 10 years / 120 months | 1,213.28 | 145,593.11 | 45,593.11 |
| 20 years / 240 months | 836.44 | 200,745.62 | 100,745.62 |
Reproduce the calculation
With P as principal, r as monthly rate, and n as payment count, EMI = P × r / (1 − (1 + r)^−n). For this example, r = 8 / 12 / 100 and n is 120 or 240. At a zero rate, EMI is P / n.
The tool computes totals from the unrounded payment and rounds each displayed result independently. Multiplying the displayed two-decimal EMI by the month count can therefore differ slightly from the displayed total. Lender schedules can also differ because of payment dates and rounding policies.
Compare a quote fairly
Run the same principal and tenure for each quoted rate, then compare fees and other costs separately. This calculator does not calculate APR or model daily interest. Check whether your lender uses a reducing-balance calculation; a flat-rate quote is not interchangeable with the same numerical reducing-balance rate.
For a variable-rate loan, repeat the calculation at several hypothetical rates to understand possible payments. That is a scenario comparison, not a forecast of the lender’s future schedule.
