Personal Loan EMI Calculator

Calculate your fixed monthly EMI, total interest, and total repayment on a personal loan using the standard reducing-balance amortization formula, plus the amount disbursed after a processing fee.

Quick Facts

Formula
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)
r is the monthly rate (annual rate ÷ 12 ÷ 100) and n is the total number of monthly installments.
Model
Reducing-balance amortization
The EMI stays fixed, but the interest/principal mix shifts every month as the outstanding balance shrinks.

How the Personal Loan EMI Calculator works

This tool computes the Equated Monthly Installment (EMI) for a personal loan — the fixed amount you repay every month until the loan is fully amortized. It uses the standard reducing-balance formula that lenders apply to installment loans of every kind, from personal loans to auto loans and mortgages.

The formula

For a loan amount P, a monthly interest rate r (the annual rate divided by 12 and by 100), and n total monthly installments, the EMI is:

EMI = P × r × (1 + r)n / ((1 + r)n − 1)

If the interest rate is 0%, the formula reduces to EMI = P / n — the loan amount split into equal installments with no interest charged. The calculator assumes monthly compounding and an ordinary amortization schedule (payments at the end of each month), the convention most personal loan lenders use.

Worked example

Take a $15,000 personal loan at 10.5% annual interest over 36 months. The monthly rate is 0.105 / 12 = 0.00875 and n = 36. The formula gives an EMI of about $487.54. Over three years that totals roughly $17,551 — the original $15,000 principal plus about $2,551 in interest. A 1% processing fee ($150) would reduce the amount actually disbursed to $14,850, even though the EMI is still calculated on the full $15,000 borrowed.

What moves your EMI most

  • Loan tenure: a longer tenure lowers the monthly EMI but increases total interest paid, because the balance stays outstanding — and accruing interest — for longer.
  • Interest rate: even a couple of percentage points changes the EMI meaningfully on larger loans, so always compare offers by their annual rate, not just the advertised EMI.
  • Processing fees: fees are typically deducted from the disbursed amount rather than added to the EMI, but they still raise the effective cost of borrowing above the stated interest rate.

Reducing-balance versus flat-rate interest

Some lenders advertise a "flat rate" applied to the original principal for the entire tenure, instead of the shrinking reducing balance this calculator uses. A flat-rate quote produces a noticeably higher effective EMI than the same headline percentage quoted on a reducing-balance basis, because flat-rate interest keeps accruing on principal you have already repaid. Always confirm which method a lender is quoting, and compare offers using the reducing-balance (EMI) rate for an apples-to-apples comparison.

Frequently Asked Questions

How is the EMI calculated?
The calculator uses the standard reducing-balance formula EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the total number of monthly installments. This is the same formula lenders use to amortize personal loans, auto loans, and mortgages.
What happens if the interest rate is 0%?
With no interest the formula reduces to EMI = P / n: the loan amount is simply divided into equal monthly installments. For example, a $15,000 loan over 36 months at 0% is $15,000 / 36 = $416.67 per month, with no interest paid.
Why does the interest portion of my EMI change every month?
Each EMI is a fixed total amount, but the split between interest and principal shifts over time. Early payments are weighted toward interest because the outstanding balance is largest; later payments are weighted toward principal as the balance shrinks. Total interest paid depends on the loan amount, rate, and tenure, not on how a single EMI happens to be split.
Does the processing fee change my EMI?
No. The EMI is calculated on the full loan amount you borrow, not the amount you actually receive after a processing fee is deducted. If a lender deducts a 1% processing fee upfront, you receive slightly less cash but still repay EMIs calculated on the full loan amount, which raises the true cost of borrowing above the stated interest rate.
