How to Calculate Your Loan EMI (Monthly Payment), With Examples
Your EMI (equated monthly instalment) is calculated with EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of months. For example, $250,000 at 6.5% for 30 years gives an EMI of about $1,580, and you’d pay about $318,900 in interest over the full term.

The EMI formula explained
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)
- P: the amount you borrow (principal).
- r: the monthly interest rate as a decimal. 6.5% a year → 6.5 ÷ 12 ÷ 100 = 0.005417.
- n: the number of monthly payments. 30 years → 360.
Each payment is the same, but the split changes over time: early payments are mostly interest, later ones mostly principal. That’s why paying extra early saves so much.
Worked example
| Loan | Rate | Term | EMI | Total interest |
|---|---|---|---|---|
| $250,000 | 6.5% | 30 years | $1,580 | ≈$318,900 |
| $250,000 | 6.5% | 15 years | $2,178 | ≈$142,000 |
| $250,000 | 5.5% | 30 years | $1,419 | ≈$261,000 |
| $20,000 (car) | 8% | 5 years | $406 | ≈$4,330 |

Three ways to pay less interest
- Shorter term: 15 years instead of 30 more than halves the total interest above, at the cost of a higher EMI.
- Lower rate: even 1 percentage point saves tens of thousands on a mortgage. Compare offers and consider refinancing when rates fall.
- Extra payments: an extra $200 a month on the $250,000 example pays it off about 8 years sooner and saves roughly $97,000 in interest.
Frequently asked questions
Is EMI the same as a mortgage payment?
The principal-and-interest part is calculated the same way. Real mortgage payments often add property tax, insurance and fees on top.
Does a lower EMI mean a cheaper loan?
Not necessarily. Stretching the term lowers the EMI but usually increases the total interest you pay.
Is this financial advice?
No. These are standard calculations for planning. Your lender’s figures may differ, so check the official loan documents.
