EMI vs Prepayment: What's the Real Cost of Your Loan?
Break down your EMI, see the interest you're really paying, and decide if prepaying makes sense.
The EMI you pay every month hides an uncomfortable truth: in the early years, most of it is interest. Understanding that split is the key to smart prepayment decisions.

Why interest is front-loaded
Interest is calculated on the outstanding balance, which is largest at the start. On a ₹50 lakh home loan at 8.5% for 20 years, you pay more than ₹53 lakh in interest alone — nearly as much as the loan itself.

Should you prepay?
Pros
- Saves the future interest on the prepaid amount.
- Shorter tenure means mental peace and lower risk.
- Partial prepayments compound your savings over time.
Cons
- Locks up cash you might need for emergencies.
- Lost opportunity cost if investments outperform your rate.
- Some loans charge prepayment penalties (usually none for floating-rate home loans).
A quick decision rule
- If your loan rate is below your expected investment return → invest instead.
- If you have high-interest debt (credit cards, personal loans) → prepay that first.
- Keep 6 months of expenses liquid before any prepayment.
- Use the calculator's amortization table to see exactly how much each prepayment saves.
