What makes an education loan arithmetic unlike other EMIs
A home loan or a car loan starts amortising from the first month. An education loan has a waiting period where interest accrues but no EMI leaves the account. The industry calls it a moratorium. During that window, two levers are in the borrower's hands: when the lender draws the tranche, and whether simple interest is paid as it arises.
Both levers change the balance the EMI is computed on. The page simulates month by month so the effect of each can be read directly from the balance chart.
Moratorium, tranche and capitalisation: the three decisions
The IBA Model Education Loan Scheme sets the moratorium as the course period plus up to twelve months. The RBI Credit Information Review states it as course period plus one year, or six months after the student secures a job, whichever is earlier. That is why the input slider stops at twenty-four months and defaults to twelve.
For a course of one year or less, one model scheme sets the moratorium at six months. State this as a typical lender rule rather than a universal one, because the actual window is on the sanction letter and the schedule.
Tranche choice matters because interest accrues on what has been drawn, not on what is sanctioned. A tranche at the start of each course year keeps the balance lower through the first half of the course than drawing it all up front.
Worked example a reader can check
Sanction ₹10,00,000 at 11 per cent, draw ₹2,50,000 at the start of each of four course years, keep interest capitalised, then run twelve months of moratorium before the first EMI. The monthly rate i is 11 divided by 1,200, or 0.009167.
| Event | Figure |
|---|---|
| Principal drawn across four years | ₹10,00,000 |
| Interest accrued across study and moratorium | about ₹4,78,055 |
| Balance when the EMI begins | about ₹14,78,055 |
| EMI over ten years of repayment | about ₹20,360 |
| Total you pay back over ten repayment years | about ₹24,43,225 |
Compare that with paying interest as it arises. The principal stays at ₹10,00,000. The EMI falls to about ₹13,775. Across the five study-and-moratorium years, roughly ₹3,85,000 goes in as interest, which is less than the ₹4,78,055 that would have capitalised, because the balance never climbs.
Tax position on an education loan
Interest paid on an education loan is deductible under the applicable provisions of the Income-tax Act 2025 (corresponding to the earlier section 80E), with no monetary cap on the interest claimed. The deduction is available only under the old regime. It runs for eight assessment years from the year repayment begins, or until the interest is fully paid, whichever is earlier.
Principal repayment does not qualify for a separate deduction. The loan must be taken from a recognised financial institution or an approved charitable institution, and for a course that qualifies under the rules. Surcharge, cess and the comparison with the new regime are outside this page, so verify them with a qualified chartered accountant before filing.
How each input moves the answer
The amount is roughly proportional at any fixed rate and tenure: twice the loan, twice the EMI. The rate works harder than it looks. On the default, a shift from 11 to 13 per cent raises the EMI by about ₹3,362 and total interest paid through study and repayment by about ₹5.1 lakh.
Course years above three stretch the capitalisation window, so the balance at repayment start climbs steeply. Extending the course from four to six years, keeping the rest of the inputs, lifts the balance at repayment start from about ₹14,78,055 to about ₹16,65,568. Moratorium months move the dial in the same direction but at a smaller slope, because they bite only on the final balance.
The repayment tenure trades a smaller EMI for a larger total. Stretching from ten to fifteen years on the default lowers the EMI by about ₹3,560 and raises the repayment-phase interest by about ₹5.8 lakh.
What the loan agreement does that this page cannot
- Collateral rule for loans above ₹7.5 lakh, where many banks insist on an acceptable security. The page's arithmetic does not account for that.
- Margin money, where the student family brings in a share of the fee alongside the loan.
- Interest subsidies under schemes such as the Central Sector Interest Subsidy Scheme, which can waive interest in the moratorium for families below a specified income.
- Sanctions at variable or step-up rates. The page uses one fixed rate; floating structures need the agreement's reset schedule.
- GST on fees. The page's principal is pure loan; add any one-time charges to your budget separately.
Before signing, three checks on the sanction letter
Confirm the moratorium wording, because the Credit Information Review phrasing of course-plus-one-year or six-months-after-job sometimes gives a different end date than the IBA model. The sanction letter is the binding document, not the website brochure.
Confirm the interest reset schedule. An eleven per cent at sanction that resets quarterly against an external benchmark can climb inside the first year, which the calculator cannot show.
Confirm the prepayment terms. RBI's Pre-payment Charges Directions, 2025 bar prepayment fees on floating-rate loans to individuals for non-business purposes, for loans sanctioned or renewed on or after 1 January 2026. A fixed-rate education loan may still carry a foreclosure fee; the schedule is on the sanction letter and the Key Facts Statement.
Frequently asked questions
What is a moratorium on an education loan?
A moratorium is the window after disbursal when the student is not asked to pay EMIs. Interest still accrues through this window. The IBA Model scheme sets it as course period plus up to twelve months, or six months after the student secures a job, whichever is earlier.
Does paying interest during the course lower the EMI later?
Yes, materially. Paying simple interest as it arises prevents it from being added to the principal on which the EMI is then computed. On the default inputs, this choice cuts the EMI from about ₹20,360 to about ₹13,775 and the total interest from both phases comes down too.
What does the tranche choice change?
Interest accrues on the amount drawn, not on the full sanction. A tranche at the start of each course year keeps the balance smaller for the first half of the course than taking the whole sanction up front, so less interest is capitalised.
Is education loan interest tax-deductible?
Yes, under the applicable provisions of the Income-tax Act 2025 (corresponding to the earlier section 80E). There is no monetary cap on the interest claimed. The deduction is only under the old regime, runs for eight assessment years from the year repayment begins, and only the interest portion qualifies.
Can the loan be prepaid without a fee?
RBI's 2025 directions bar prepayment fees on floating-rate loans to individuals for non-business purposes, for loans sanctioned or renewed on or after 1 January 2026. Fixed-rate loans are outside this rule. Check the sanction letter and the Key Facts Statement for the exact position.
What rate should I enter in the calculator?
Use the rate on your sanction letter or the lender's current published rate for the course type. The default of 11 per cent is a sample, not a quote. The rate will often reset against an external benchmark through the life of the loan.
Does the calculator account for interest subsidies?
No. Subsidy schemes such as the Central Sector Interest Subsidy Scheme can waive interest for eligible families through the moratorium. The page runs plain arithmetic on the rate you enter. Apply any waiver separately to the figures.
