EMI Calculator: what it does and when to use it
An EMI calculator works out the fixed monthly instalment needed to repay a loan over its tenure, along with the total interest you will pay. It works for home loans, car loans, personal loans and education loans.
Try different tenures and rates before you apply: a shorter tenure raises the EMI but can cut total interest by lakhs on a home loan.

Method
How this calculation works
The exact formula and assumptions behind the numbers above.
Formula
EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
P = principal, r = annual rate ÷ 12 ÷ 100, n = tenure in months.
Assumptions
- Early instalments are mostly interest; later ones mostly principal.
- A longer tenure lowers the EMI but raises total interest.
- Even a small rate reduction saves a large amount over a long loan.
Questions
Frequently asked questions
Does a longer tenure help?
It reduces the monthly outgo, but you pay more interest overall because the balance stays outstanding longer.
Should I prepay?
Prepaying early in the loan saves the most interest, since that is when the interest component is largest. Check for prepayment charges first.
What is a safe EMI to income ratio?
Many lenders cap total EMIs at roughly 40–50% of net monthly income. Staying well below that leaves room for savings and emergencies.
Does the EMI change with a floating rate?
When a floating rate changes, lenders usually adjust the tenure first and the EMI only if needed. Re-run the calculator with the new rate to see the effect.
