Prepay the loan, or invest the money instead? The honest version of this comparison
computes the guaranteed side precisely and refuses to guess the side nobody can know in advance — what
a market will return, and which way the rupee moves. Enter your loan's own terms and see exactly where
the guaranteed ground is. Nothing you enter below reaches any server.
Your loan
The rulebook, verified
Prepaying guarantees a return equal to the loan's own rate — investing only wins if it beats that, and nothing can guarantee it will verified
Every rupee used to prepay a loan stops accruing that loan's interest rate, permanently and without risk — mathematically identical to earning that rate, guaranteed, on that rupee. Investing the same money instead only comes out ahead if the investment's actual return exceeds the loan's rate over the same period, and no page, calculator or advisor can guarantee what a market will return. This page computes the guaranteed side of the comparison precisely and states plainly that it cannot compute the other side — not because the arithmetic is hard, but because the honest answer to 'what will the market return' is that nobody knows in advance.

As of 1 January 2026, most individuals can prepay a floating-rate education loan with no foreclosure charge at all — a friction that used to make prepaying expensive verified
The RBI's Pre-payment Charges on Loans Directions, 2025, effective 1 January 2026, bar lenders from charging foreclosure or prepayment penalties on floating-rate loans to individual borrowers — education loans named explicitly — for loans sanctioned or renewed on or after that date, regardless of whether the prepayment comes from savings, a balance transfer, or refinancing. A loan sanctioned before that date, or one carrying a fixed rather than floating rate, may not be covered by this specific rule and its own agreement should be checked directly rather than assumed.

Prepaying reduces future interest — which mechanically reduces the future Section 80E deduction too verified
Section 80E lets the named borrower deduct the full interest paid on an education loan, with no ceiling, for eight assessment years from the year repayment begins (see /tools/80e for the deduction mechanics in full — this figure only states how it interacts with prepayment). Because the deduction is on interest ACTUALLY PAID, prepaying principal reduces the interest that accrues in later years, which reduces the 80E deduction available in those same later years. This is not an argument against prepaying — the loan's own rate is still a guaranteed return — but treating the interest deduction and the guaranteed-return case for prepaying as two independent wins overstates the combined benefit; they partially trade off against each other in later years of the eight-year window.

Earning outside India and repaying a rupee loan means currency movement changes the real cost — in a direction nobody can predict in advance verified
For a borrower earning in a currency other than the rupee, the loan's cost in their own earning currency moves with the exchange rate: a weakening rupee lowers the real cost of a fixed rupee repayment, and a strengthening rupee raises it. This is a real factor in the comparison, and it is also not something this page, or anyone, can forecast — treating a specific direction as the likely one would be a guess dressed as analysis. The honest way to hold this factor is as a source of extra variance around whichever choice is made, not as a reason to lean toward either side.

Funding the prepayment itself is a separate question, already answered elsewhere on this site verified
This page compares prepaying against investing — it does not restate what happens when money actually moves to make the prepayment. Whether that remittance triggers tax collected at source depends on how it is funded and routed (see /tools/edu-tcs), and if the money originates in India rather than abroad, repatriation and remittance limits apply on the Indian side (see /tools/lrs). Treat this page's comparison as the decision, and those two as the separate mechanics of executing whichever side is chosen.

This page will not tell you whether investing beats prepaying — that depends on a
market return and an exchange-rate movement, neither of which any page can know in advance. What it
can show is the guaranteed side of the comparison, precisely, and the frictions (or the absence of
them) that used to make the decision harder than the arithmetic alone.
