Education Loan Offer Comparison Calculator
Short answer. Two education loan offers with different rates, fees and moratorium terms cannot be compared by the headline rate. This calculator puts two sanction letters side by side and shows the balance when repayment starts, the EMI, and the total cost. Often the biggest saving is paying interest during the course, not a lower rate.
Assumes the full amount is disbursed on day one. Real loans disburse in instalments each semester, which lowers the interest during the course for every option, so treat the totals as an upper bound and the comparison as the useful part.
Why the headline rate is the wrong number to compare
When two sanction letters arrive, the instinct is to take the lower rate. But an education loan has three costs that a rate alone does not show: the fees taken on day one, the interest that builds up while you study and earn nothing, and the length of the repayment. Change any of the three and the cheaper offer can flip.
The default numbers above show one version of this. Offer A has the lower rate but lets interest compound during the course. Offer B charges simple interest but at a higher rate and with double the processing fee. Here the rate gap wins and A is cheaper, by close to ₹2 lakh. Narrow the rate gap and B starts to catch up. The point is not that one structure always wins. It is that you have to run the numbers for your own two letters.
The biggest lever is usually not the rate
Switch either offer to "I pay it every month" and watch the total fall. On a ₹30 lakh loan at 10 percent, with a 30 month course and grace period and a 12 year repayment, paying the interest as it falls due instead of letting it compound cuts total interest by about ₹7.1 lakh, because the principal never grows before repayment starts. Taking half a point off the rate on the same compounding loan saves about ₹2.4 lakh.
The catch is cash flow: in that example someone has to find about ₹7.5 lakh of interest over the 30 months while you study, which is why the calculator shows it as its own row. If a parent can cover it even partly, it is usually the cheapest money you will ever save on the loan. Our guide on interest during the moratorium period explains how banks apply it, and the moratorium calculator works it out month by month.
What to pull from each sanction letter
| Field | Where to find it | Why it matters |
|---|---|---|
| Rate and its benchmark | Interest clause, often written as a benchmark plus a spread | A floating rate moves with the benchmark, so the rate today is not the rate for 12 years |
| Processing fee | Charges schedule, usually a percentage with a minimum and a cap, plus GST | Paid upfront and never refunded, even if you cancel |
| Moratorium terms | Repayment clause: course period plus grace months, and how interest is charged | Decides how big the balance is before your first EMI |
| Tenure | Repayment clause | Longer means a smaller EMI and much more total interest |
| Insurance and other charges | Annexures and the key fact statement | Sometimes bundled into the loan, so you pay interest on it too |
