EMI (Equated Monthly Instalment) is a fixed monthly payment made by a borrower to a lender on a specified date each month. It consists of both the principal and interest components.
EMI = P × r × (1 + r)n / ((1 + r)n - 1)An EMI calculator computes the fixed monthly instalment on a loan from three inputs — principal, annual interest rate and tenure — using the formula EMI = P × r × (1+r)n / ((1+r)n − 1).
SnoopTool's EMI calculator is free, needs no sign-up, and runs entirely in your browser, so loan figures never leave your device. It also prints a month-by-month amortisation schedule showing how each instalment splits between principal and interest.
| Inputs required | Principal (P), annual interest rate, tenure in months or years |
|---|---|
| Formula | EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1), where r = annual rate ÷ 12 ÷ 100 |
| Typical safe EMI-to-income ratio | 40–50% of net monthly income |

At 8.5% a year over 20 years, every ₹1 lakh of home loan costs ₹868 a month. That single number is the fastest way to size a loan in your head: a ₹50 lakh loan is 50 × ₹868 = ₹43,400 a month, and a ₹75 lakh loan is about ₹65,100. The table below gives the EMI on exactly ₹1,00,000 of principal, so you can multiply by the number of lakhs you are borrowing at any rate and tenure.
| Interest rate | 10 years | 15 years | 20 years | 25 years | 30 years |
|---|---|---|---|---|---|
| 7.50% | ₹1,187 | ₹927 | ₹806 | ₹739 | ₹699 |
| 8.00% | ₹1,213 | ₹956 | ₹836 | ₹772 | ₹734 |
| 8.50% | ₹1,240 | ₹985 | ₹868 | ₹805 | ₹769 |
| 9.00% | ₹1,267 | ₹1,014 | ₹900 | ₹839 | ₹805 |
| 9.50% | ₹1,294 | ₹1,044 | ₹932 | ₹874 | ₹841 |
| 10.00% | ₹1,322 | ₹1,075 | ₹965 | ₹909 | ₹878 |
Read the table the other way and the tenure trap is obvious. Stretching a loan from 20 years to 30 years cuts the monthly EMI at 8.5% from ₹868 to ₹769 per lakh — an 11% saving on the cheque you write each month — but you write 120 more of them. On a ₹50 lakh loan that is roughly ₹54.1 lakh of interest over 20 years versus about ₹88.4 lakh over 30 years.
On a ₹50 lakh loan at 8.5% for 20 years, paying one extra ₹1 lakh at the end of every year closes the loan in 14 years instead of 20 and saves about ₹18.6 lakh in interest. The saving is large because every prepaid rupee is applied to principal, and in the early years of an EMI schedule the interest component is the majority of each instalment.
| Annual prepayment | Loan closes in | Total interest paid | Interest saved |
|---|---|---|---|
| None | 20 years (240 EMIs) | ₹54,13,879 | — |
| ₹1,00,000 a year | 14 years (168 EMIs) | ₹35,58,489 | ₹18,55,390 |
| ₹2,00,000 a year | 11 years (132 EMIs) | ₹27,13,321 | ₹27,00,558 |
Two conditions decide whether this is the right move. Ask the lender to reduce the tenure, not the EMI — keeping the EMI constant is what produces the numbers above; cutting the EMI instead gives back most of the saving. And check the prepayment charge: on floating-rate home loans to individual borrowers, RBI rules bar foreclosure and prepayment penalties, but fixed-rate loans and most personal and car loans can still carry a charge of roughly 2–5% of the outstanding amount.
Most Indian lenders cap total EMIs at 40–50% of net monthly income (the FOIR, or fixed-obligation-to-income ratio), so a ₹1,00,000 take-home salary supports roughly ₹40,000 of EMI and a home loan near ₹46 lakh at 8.5% over 20 years. Existing car loans, personal loans and credit-card minimums are counted inside that ceiling, not on top of it.
| Net monthly salary | EMI capacity (40%) | Indicative loan |
|---|---|---|
| ₹40,000 | ₹16,000 | ~₹18.4 lakh |
| ₹60,000 | ₹24,000 | ~₹27.7 lakh |
| ₹80,000 | ₹32,000 | ~₹36.9 lakh |
| ₹1,00,000 | ₹40,000 | ~₹46.1 lakh |
| ₹1,50,000 | ₹60,000 | ~₹69.1 lakh |
| ₹2,00,000 | ₹80,000 | ~₹92.2 lakh |
Separately, lenders cap the loan-to-value ratio, so the sanctioned amount is also limited by the property price: broadly up to 90% of value for loans up to ₹30 lakh, 80% between ₹30 lakh and ₹75 lakh, and 75% above ₹75 lakh. Whichever ceiling — income or LTV — is lower is the one that binds.
Method: every figure above is computed from the standard reducing-balance formula EMI = P × r × (1+r)n / ((1+r)n − 1) and rounded to the nearest rupee, using the same engine as the calculator at the top of this page. Interest rates are an illustrative band, not quoted offers — confirm your lender's current card rate, processing fee and any fixed-rate prepayment charge before deciding.

At 8.5% a year over 20 years, ₹1 lakh of home loan costs ₹868 per month, so a ₹50 lakh loan works out to about ₹43,400. At 8% for 20 years it is ₹836 per lakh, and at 9.5% it is ₹932 per lakh. Multiply the per-lakh figure by the number of lakhs you are borrowing to size any loan instantly.
On a ₹50 lakh home loan at 8.5% for 20 years (EMI ₹43,391), paying an extra ₹1 lakh at the end of every year closes the loan in about 14 years instead of 20 and saves roughly ₹18.6 lakh in interest. Paying ₹2 lakh a year closes it in about 11 years and saves about ₹27 lakh. Ask the lender to reduce the tenure rather than the EMI, or you give back most of the saving.
Most Indian lenders cap total EMIs at 40-50% of net monthly income, so a ₹1,00,000 take-home salary supports about ₹40,000 of EMI, which is roughly a ₹46 lakh home loan at 8.5% over 20 years. Any running car loan, personal loan or credit-card minimum is counted inside that ceiling, and the loan-to-value cap on the property may reduce the sanction further.
A 30-year loan has the smaller monthly EMI but costs far more in total. At 8.5%, ₹1 lakh of principal costs ₹868 a month over 20 years versus ₹769 over 30 years - about 11% less each month, but for 120 extra months. On a ₹50 lakh loan that is roughly ₹54.1 lakh of interest over 20 years against about ₹88.4 lakh over 30 years.
