Understanding EMI, Total Interest and Tenure
Why lenders quote a low monthly EMI while quietly charging you tens of thousands in interest — and how to see through it.
Banks advertise the EMI because it is the smallest number in the deal. Total interest is almost always many multiples of the monthly payment.
Two loans, same EMI, different cost
A 5-year loan at 10% and a 10-year loan at 6% can produce the same monthly EMI. The 10-year loan usually costs more in total interest, even though the rate is lower. Always compare total interest paid, not just EMI.
Run three scenarios
Whenever you look at a loan offer, plug it into our Loan EMI Calculator three times:
- Shortest tenure you can afford — the cheapest option.
- The offer's default tenure.
- Longest tenure — the "cash-flow friendly" trap.
The difference in total interest is usually shocking.
Prepayment usually wins
If your loan allows penalty-free prepayment, a lump-sum payment in the early years dramatically cuts total interest. Verify the fine print — some lenders quietly charge a foreclosure fee.
Simple vs. compound interest
Personal loans typically use amortising (compound-style) interest. Fixed deposits and savings accounts use compound interest in your favour. Model both with our Compound Interest Calculator.
