Most education loans in India come with a moratorium period — the gap between when your loan is disbursed and when your first EMI is due, typically covering your course duration plus a 6-12 month grace period. What many students and families don't realize: interest doesn't wait for the moratorium to end. It starts accruing from the day the loan is disbursed, whether or not anyone is actually paying it.
Three ways to handle moratorium interest, and the trade-offs of each:
- Pay nothing (full capitalization) — the default for most borrowers. Interest accrues silently every month of the moratorium. At the end, all of that unpaid interest gets added to your principal — you now owe EMIs on a larger "capitalized" balance than you originally borrowed. This is the easiest option (nothing to pay while studying) but also the most expensive over the life of the loan, because you end up paying interest on interest for the entire remaining tenure.
- Pay interest only (simple servicing). You (or your parents) pay just the interest portion each month during the moratorium — no principal, but the balance never grows beyond what you originally borrowed. This requires someone to have spare income during the study years, which isn't always realistic for a student with no income yet, but it materially reduces the total cost.
- Pay part of the interest. A middle ground — servicing 30-50% of the accruing interest reduces (but doesn't eliminate) the capitalization effect, useful if a parent can contribute something but not the full monthly interest amount.
A worked example. Take a ₹15,00,000 education loan at 10.5%, with a 48-month moratorium (a 4-year course plus grace period).
- Full capitalization: roughly ₹7.79 lakh of interest accrues silently over 48 months and gets added to principal — your loan effectively starts at ₹22.79 lakh instead of ₹15 lakh once repayment begins.
- Simple servicing: paying roughly ₹13,000-14,000/month in interest during the moratorium (starting lower, rising as the rate compounds if unpaid) keeps the balance at ₹15 lakh throughout. Compared to full capitalization, this saves approximately ₹6.3 lakh over the life of the loan — a substantial number for a decision that often gets made by default rather than by choice.
Why the gap is so large. This is compounding interest working against you during a period when you're making zero payments. Every month of unpaid interest gets added to a growing balance, and next month's interest is then charged on that larger number — a snowball effect that runs uninterrupted for the entire moratorium if nothing is paid.
Who should consider servicing interest during the moratorium:
- Parents with steady income who can comfortably absorb ₹10,000-15,000/month without financial strain, since it demonstrably reduces the total family cost of the loan.
- Families expecting a long moratorium (5+ year courses, or courses with a longer grace period) — the longer the moratorium, the more capitalization compounds against you.
Who might reasonably choose full capitalization anyway:
- Families with no spare income during the study years — the whole point of an education loan is to defer cost until the student is earning, and forcing a payment that causes real financial strain isn't automatically the right call just because it's mathematically cheaper.
- Cases where the loan amount is small enough that the capitalization gap in absolute rupee terms is modest.
Don't forget Section 80E. Once repayment begins, 100% of the interest paid is deductible from taxable income for up to 8 years, with no upper cap. This applies to whoever actually pays the interest — student or parent — so a family choosing to service interest during the moratorium may also be able to start claiming this deduction earlier, depending on when repayment technically begins versus when interest is paid.
