Loan & EMI Calculator

Whenever you borrow a fixed amount and repay it in equal monthly installments — a personal loan, car loan, or business loan — the math behind your payment is the same. Enter the loan amount, annual interest rate, and term below to see your monthly payment and exactly how much of it is interest.

How It Works

The standard amortizing-loan formula used by virtually every bank is:

EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]

Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the total number of monthly installments. Every payment you make is split between interest (charged on the remaining balance) and principal (which actually reduces what you owe) — early payments are mostly interest, and later payments are mostly principal, even though the total monthly amount never changes.

Worked Example

Take a $20,000 loan at 9.5% annual interest over 5 years. The monthly rate works out to about 0.79%, and over 60 payments that produces an EMI of roughly $420/month. Over the full term you'd repay about $25,210 in total — the original $20,000 plus around $5,210 in interest. Shorten the term to 3 years and the monthly payment rises to around $640, but total interest drops to roughly $3,020, since the bank charges you for fewer months of borrowing.

Frequently Asked Questions

What does EMI stand for?
Equated Monthly Installment — a fixed payment made every month that covers both interest and a portion of the principal, so the loan is fully paid off by the end of its term.
Why does most of my early payment go to interest?
Interest is calculated on the outstanding balance, which is highest at the start of the loan. As the balance shrinks with each payment, less of your fixed EMI is needed for interest, so more goes toward principal.
Does this calculator work for car loans and personal loans too?
Yes — the amortization formula is identical for any fixed-rate, fixed-term loan with equal monthly payments, regardless of what the loan is for.
