How to calculate EMI

A daily loan search — home, car, and phone EMIs in plain maths. This page has 50 important questions and answers. Original explainer for daily search — not a government login or live tracker.

EMI (Equated Monthly Instalment) is a fixed monthly payment that covers interest and principal on a reducing-balance loan. The usual formula is EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the principal, r is the monthly rate (annual rate ÷ 12 ÷ 100), and n is the number of months.

A 12% annual rate is 1% per month (0.01). Longer tenure shrinks the EMI but increases total interest. A processing fee is extra — it is not inside the pretty EMI a banner shows unless they say so.

Prepayment can cut interest; some loans charge a fee. This is education, not a loan offer. Use the lender’s official calculator for the number that will be auto-debited.

Answer: follows the lender’s schedule, not your mental maths

The first debit SMS is the check.

Answer: the same rupee cost as 12% simple on the original P for the whole tenor

Reducing-balance is the usual EMI story.

42. Excel PMT or a bank calc is

Fees still sit outside PMT.

43. Currency of the EMI should

Answer: match the loan (INR for a rupee loan)

FX loans add rate risk.

44. A gold-loan EMI vs bullet is

Answer: two different repayment shapes

Ask which you signed.
