What EMI Calculator does
Enter the loan amount, the annual interest rate and the term, and the calculator returns the equated monthly instalment on a reducing balance, the total interest, the total repayable and interest as a percentage of the loan. Below that, a yearly table shows how much principal and interest you pay each year and the balance left. With the default 500,000 at 8.5% over 20 years, the EMI is 4,339.12 and interest totals 541,387.88, more than the amount borrowed. The same formula covers home, car and personal loans, and an Extra months field handles terms such as 7 years 6 months. Figures are plain numbers with no currency symbol.
EMI per lakh chart by interest rate and tenure
Monthly EMI for every 100,000 (1 lakh) borrowed, on a reducing balance. Multiply by your loan size in lakhs: for 25 lakh at 9% over 15 years, 1,014.27 × 25 is about 25,357 a month.
| Interest rate | 3 years | 5 years | 7 years | 10 years | 15 years | 20 years |

Scaling by lakhs can differ from the calculator by a few paise, or up to about a rupee on loans of several crore, because each cell is rounded to two decimals.
Home, car and personal loan EMI examples
The formula is identical for every loan type. What changes is the typical amount, rate and tenure, and with them the share of your money that goes on interest.
Home loan
Loan amount 4000000, Annual interest rate 8.5%, Loan term 20 years
Monthly EMI 34,712.93 over 240 payments. Total interest 4,331,103.04, Total repayable 8,331,103.04, Interest as % of loan 108.3%
Car loan
Loan amount 800000, Annual interest rate 9.2%, Loan term 7 years
Monthly EMI 12,952.61 over 84 payments. Total interest 288,019.27, Total repayable 1,088,019.27, Interest as % of loan 36%
Personal loan
Loan amount 500000, Annual interest rate 12.5%, Loan term 5 years
Monthly EMI 11,248.97 over 60 payments. Total interest 174,938.15, Total repayable 674,938.15, Interest as % of loan 35%
Yearly breakdown: interest paid falls from 58,199.43 in year 1 to 8,712.29 in year 5.
A tenure of 7 years 6 months
Loan amount 600000, Annual interest rate 9%, Loan term 7 years, Extra months 6
Monthly EMI 9,191.94 over 90 payments. Total interest 227,274.20, Total repayable 827,274.20
The yearly table shows a short eighth row covering the final six instalments.
How tenure changes EMI and total interest on a 30 lakh loan
Loan amount 3,000,000 at 8.5% a year. Each extra five years trims the instalment by less and adds between about 850,000 and 1,060,000 to the interest bill.
| Tenure | Monthly EMI | Total interest | Total repayable | Interest as % of loan |
|---|---|---|---|---|
| 10 years | 37,195.71 | 1,463,484.80 | 4,463,484.80 | 48.8% |
| 15 years | 29,542.19 | 2,317,593.61 | 5,317,593.61 | 77.3% |
| 20 years | 26,034.70 | 3,248,327.28 | 6,248,327.28 | 108.3% |
| 25 years | 24,156.81 | 4,247,043.75 | 7,247,043.75 | 141.6% |
| 30 years | 23,067.40 | 5,304,265.62 | 8,304,265.62 | 176.8% |
A rate change matters too: the same loan over 20 years at 8.9% instead of 8.5% costs 26,799.14 a month, 764.44 more, and 183,466.28 extra interest over the term.
EMI formula with a worked calculation
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
P is the principal, r the monthly interest rate as a decimal and n the number of monthly instalments. For 500,000 at 8.5% over 20 years, r = 8.5 ÷ 12 ÷ 100 = 0.0070833 and n = 240, which gives an EMI of 4,339.12. Each month the interest due is the outstanding balance × r, and the rest of the instalment reduces the principal. In month one that is 3,541.67 of interest and 797.45 of principal. Because the balance shrinks a little every month, the interest portion falls and the principal portion grows while the EMI stays fixed. At a rate of 0% the calculator simply divides the loan by the number of months.
Reading the yearly breakdown table
Each row of the Yearly breakdown covers twelve instalments and shows Principal paid, Interest paid and the Balance at the end of that year. It is a yearly summary rather than a month-by-month schedule.
The table is where the real shape of a loan shows up. On 500,000 at 8.5% over 20 years, the balance after year 1 is still 490,048.85. After ten full years, with half the instalments paid, the balance is 349,969.11, so about 70% of the loan is still owed. Most of the principal is cleared in the last third of the term.
This is why a part-prepayment made early saves far more interest than the same amount paid late, and why selling or refinancing in the first few years leaves a bigger outstanding balance than borrowers expect. To see the effect of a lump-sum prepayment, read the Balance for the relevant year, subtract the prepayment and run that figure as a new loan over the remaining term.
What the calculation leaves out
- Flat-rate loans. The calculator uses the reducing-balance method. A flat rate charges interest on the full principal for the whole term: 100,000 at a 10% flat rate for 3 years means 30,000 interest and an EMI of 3,611.11, against 3,226.72 on a 10% reducing-balance rate.
- Processing fees, insurance premiums, documentation charges and taxes on those fees, which raise the true cost of a loan.
- Floating-rate resets. The EMI assumes one rate for the whole tenure. Rerun the numbers at a rate one point higher to see how a rise would affect you.
- Regular prepayments, step-up EMIs and moratorium periods.
- Terms beyond 50 years. The loan term is capped at 600 monthly instalments and a longer one returns an error.
- Indian digit grouping and currency symbols. Results use standard thousands separators, so 10 lakh appears as 1,000,000.
