A personal loan calculator tells you your monthly EMI from three inputs: loan amount, interest rate and tenure. But the EMI is only half the story. Use the same calculator to see the total interest and total amount you will repay, and then add fees from the lender’s Key Facts Statement. That full number is what you should compare across offers.
What inputs does a personal loan calculator need?
| Input | What to enter | Tip |
|---|---|---|
| Loan amount | The amount you want to borrow | Borrow only what you need |
| Interest rate | The yearly rate quoted by the lender | Check whether it is fixed or floating |
| Tenure | Months or years to repay | Try several tenures side by side |
Most calculators then show the EMI, total interest and total repayment. Our guide to EMI calculators in India covers the common types.
How is the EMI worked out?
Personal loans in India usually use the reducing balance method. Interest each month is charged only on the principal still unpaid. In the early months, more of your EMI goes to interest. Later, more goes to principal.
The formula in words: take the monthly rate (yearly rate divided by 12, as a decimal). Multiply the loan amount by this monthly rate and by (1 plus the monthly rate) raised to the number of months. Then divide by (1 plus the monthly rate) raised to the number of months, minus 1. A personal loan calculator does this for you in a second.
How does tenure change the total cost?
Illustrative example. Loan of Rs 3,00,000 at an assumed 14% a year, reducing balance. Figures are rounded and exclude fees.
| Tenure | EMI | Total interest | Total repaid |
|---|---|---|---|
| 2 years | Rs 14,404 | Rs 45,693 | Rs 3,45,693 |
| 3 years | Rs 10,253 | Rs 69,118 | Rs 3,69,118 |
| 4 years | Rs 8,198 | Rs 93,501 | Rs 3,93,501 |
| 5 years | Rs 6,980 | Rs 1,18,829 | Rs 4,18,829 |
Going from 2 years to 5 years cuts the EMI by more than half but more than doubles the interest. Pick the shortest tenure whose EMI you can pay comfortably every month. Read more on why personal loan tenure choice matters.
Why should you check the APR in the Key Facts Statement?
A calculator uses only the interest rate. Real loans also carry a processing fee and other charges. The RBI circular on the Key Facts Statement requires lenders to give a KFS for retail term loans, with the Annual Percentage Rate, which covers interest and all other charges, plus a repayment schedule. Lenders cannot charge fees not in the KFS without your explicit consent.
Illustrative example. If the Rs 3,00,000 loan above carries a 2% processing fee, Rs 6,000 may be deducted, so you receive Rs 2,94,000 but repay EMIs on Rs 3,00,000. That pushes the true cost above the 14% headline rate. The APR captures this. Compare offers on APR, not just on rate.
What other charges should you know about?
- Penal charges. The RBI circular on penal charges says late payment penalties must be penal charges, not penal interest added to your rate, and must not be capitalised. They must be disclosed in the KFS.
- Floating rate resets. For EMI based personal loans on floating rates, the RBI circular on reset of floating interest rates says that at a reset you can choose a higher EMI, a longer tenure or both. Lenders must also give a quarterly statement showing principal and interest recovered, the EMI, EMIs left and the APR.
Can prepayment lower the total cost?
Yes. Paying part of the principal early reduces the balance that attracts interest. Under the RBI Pre-payment Charges on Loans Directions, 2025, lenders cannot levy pre-payment charges on floating rate loans to individuals for non-business purposes sanctioned or renewed on or after 1 January 2026. For fixed rate loans, charges follow the lender’s policy and must be disclosed in the KFS. Many calculators let you add a part prepayment to see the effect.
If your current loan already feels costly, see signs you are paying too much on a personal loan and what to do if your interest is too high.
Does your credit score affect the result?
The calculator cannot tell you what rate you will get. Lenders consider your credit profile. TransUnion CIBIL notes that a higher score indicates lower credit risk and that many loan applications in a short period may hurt your score. So compare offers carefully instead of applying everywhere.
If the numbers show you are already paying high interest across loans, card dues or EMIs, one structured EMI may cost less. Check your options with BillCut and run the numbers before you decide.

Frequently asked questions
What does a personal loan calculator show?
It shows your EMI, total interest and total amount repaid, based on the loan amount, interest rate and tenure you enter.
Is the calculator result final?
No. It is an estimate. Your actual rate, fees and EMI are set by the lender and shown in the Key Facts Statement.
Should I choose a lower EMI or a shorter tenure?
A longer tenure lowers the EMI but raises total interest. Choose the shortest tenure with an EMI you can pay comfortably.
What is APR?
The Annual Percentage Rate is the yearly cost of the loan including interest and other charges. Lenders must show it in the Key Facts Statement.
Does the calculator include the processing fee?
Most simple calculators do not. Add the fee yourself or compare offers using the APR.
Can I prepay a personal loan without charges?
RBI rules bar pre-payment charges on floating rate loans to individuals for non-business purposes sanctioned or renewed from 1 January 2026. Fixed rate loans follow the lender’s disclosed policy.
What happens to my EMI if a floating rate goes up?
At a reset, RBI rules let you choose a higher EMI, a longer tenure or a mix of both.
