Frequently asked questions

What formula is used?

EMI = P ร— r ร— (1 + r)^n รท ((1 + r)^n โˆ’ 1), where r is the monthly rate and n the number of months.

Does it account for prepayment?

Not yet โ€” the schedule assumes every instalment is paid exactly on time with no part-prepayment.

Why does my bank quote a different EMI?

Usually one of three things: processing and documentation fees added to the principal, an insurance premium bundled into the loan, or a rate that differs from the advertised one once your profile is assessed. The formula itself is standard, so a gap almost always means the inputs are not the ones the bank is using.

What happens to my EMI if the interest rate changes?

On a floating-rate loan most lenders hold the EMI steady and extend the term instead, which is why a rate rise can quietly add years without changing anything you notice each month. Ask explicitly which one your lender adjusts, and check the outstanding term after any rate change.
