How EMI is calculated
EMI stands for Equated Monthly Instalment - a fixed monthly amount that covers both principal and interest, paid on a set date until the loan is fully repaid.
- P - Loan principal (the amount borrowed)
- R - Monthly interest rate (annual rate ÷ 12 ÷ 100)
- N - Total number of months (years × 12)
For floating-rate loans the rate can reset over time, in which case the lender revises either the EMI or the tenure.
What makes up each EMI
Every EMI splits into a principal component (which pays down the borrowed amount) and an interest component. In the early years the interest share is larger; as the loan ages, the principal share grows.
Common Indian loans
- Home loans - typically 8%–11% p.a., up to 30 years
- Car loans - typically 8%–14% p.a., up to 7 years
- Personal loans - typically 10.5%–24% p.a., 1–7 years
Prepayment & foreclosure
Prepayment means clearing a loan ahead of schedule - either part-prepay (a lump sum that reduces the outstanding principal) or full foreclosure (closing the loan entirely).
Why it helps
- Reduces total interest paid over the loan's life
- Helps you become debt-free faster
- Lowers your overall debt burden on your credit profile
- Frees up monthly cash flow for other goals
What the rules say
Based on RBI directions and typical lender policy (exact rules vary by lender and product):
- Most regulated lenders don't charge prepayment fees on floating-rate home loans taken by individuals.
- Fixed-rate loans may carry prepayment charges, especially during an initial lock-in period.
- Personal and car loan prepayment fees commonly fall in the 2–5% range of outstanding principal.
Should you prepay?
Prepayment usually makes sense when you have surplus funds, your loan rate exceeds your expected after-tax investment returns, and prepayment fees are minimal or zero.
