Moratorium, simple interest and EMI: the repayment maths students skip

The moratorium is the most misunderstood feature of an education loan. Students hear "no repayment during the course" and assume the loan pauses. It does not. Interest continues to accrue from the day the first rupee is disbursed.

What the moratorium actually is

The moratorium is the course duration plus a grace period — commonly six months to a year after the course ends, depending on the lender. During this window you are not required to pay full EMIs. On most products, unpaid interest accrued in this period is added to your principal, and you then pay interest on that larger balance for the remaining tenure. That is compounding working against you at exactly the moment you have least income.

Why simple interest during the moratorium pays for itself

Most lenders offer the option to pay only the accruing interest each month while you study. The amounts are modest relative to a full EMI, and many families cover them out of regular income.

The effect is significant. On a large multi-year loan, servicing interest through the study period rather than capitalising it can reduce total repayment by a sum comparable to a semester's tuition, because your principal never inflates. Several lenders also offer a small rate concession for students who service interest during the moratorium — ask explicitly, because it is not always volunteered.

If you cannot service the full interest, pay part of it. Partial servicing still reduces the amount capitalised.

Sizing an EMI you can actually live with

Work backwards from expected income, not from what a lender is willing to approve.

• Estimate a conservative post-study monthly take-home in the currency you will earn in.
• Target an EMI at or below roughly a quarter of that take-home.
• If the required EMI exceeds that, your options are: borrow less, extend the tenure, offer security to reduce the rate, or reduce the cost of your programme choice.

Longer tenure lowers the EMI but increases total interest. That is not automatically a bad deal — a comfortable EMI you never default on is worth more than a theoretically optimal one that strains the household — but make the choice knowingly.

Floating rates and resets

Most education loans are floating. The rate is a benchmark plus a spread, and it resets periodically. When the benchmark moves, lenders usually keep the EMI constant and change the tenure, or keep the tenure and change the EMI. Ask which convention your lender follows, because a rising rate under the first convention silently extends your loan by months or years.

Prepayment is your strongest lever

Education loans to individuals on floating rates generally do not carry foreclosure charges, though you should confirm this in your sanction letter. That makes prepayment the cheapest financial move available to a working graduate.

• Prepay early in the tenure. Interest is front-loaded, so a prepayment in year two saves far more than the same amount in year seven.
• Direct bonuses and windfalls to principal rather than to lifestyle inflation.
• When you prepay, ask the lender in writing to reduce the tenure rather than the EMI, if your budget can hold the current EMI. Reducing tenure saves more interest.

Tax relief worth knowing about

Interest paid on an education loan taken from an approved lender for higher studies is deductible under Section 80E for the person repaying the loan, for a limited number of years starting from when repayment begins. Principal is not deductible. Keep the lender's annual interest certificate. Rules change, so confirm the current position with a tax adviser before you rely on it in your planning.

A checklist for the sanction letter

• Moratorium length, and exactly when the first EMI is due.
• Whether interest during the moratorium is capitalised, and whether servicing it earns a rate concession.
• Benchmark, spread and reset frequency.
• Prepayment and foreclosure terms.
• Whether insurance is bundled and financed into the loan.
• Late payment charges and the auto-debit arrangement.
