Education Loan Total Cost Calculator
See the total interest on an education loan and what prepayment would save.
The EMI is the number banks quote. The total interest is the number that matters. This calculator amortises an education loan month by month, shows how much of each year's payment goes to interest rather than principal, and quantifies what a modest monthly prepayment would save.

What the Education Loan Total Cost Calculator does
On a ₹15 lakh loan at 10.5% over seven years, roughly ₹6 lakh is interest — about 40% of the amount borrowed. Because interest is charged on the outstanding balance, the early years are heavily weighted towards interest, which is exactly why prepayment early in the term is so effective.
Education loans have one advantage over most other borrowing: Section 80E allows the entire interest to be deducted from taxable income for up to eight years, with no upper limit.
How to use this tool
- Enter the loan amount, interest rate and repayment tenure the bank has offered.
- Add any extra amount you could realistically pay each month, even ₹2,000.
- Select your expected income tax rate so the Section 80E benefit can be estimated.
- Read the total interest first, then the year-by-year table to see how the split between interest and principal shifts.
- Compare tenures: shortening from seven years to five raises the EMI but cuts interest substantially.
Formula and method
EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1)
Each month:
Interest = Outstanding balance × monthly rate
Principal = Payment − Interest
Balance = Balance − Principal
Total interest = sum of all monthly interest until the balance reaches zero.
80E benefit = Total interest × your marginal tax rate
Worked example
Example: ₹15,00,000 at 10.5% over 7 years
| EMI | ₹25,297 |
| Total paid | ₹21,24,948 |
| Total interest | ₹6,24,948 |
| With ₹5,000/month extra | Interest falls to ≈ ₹4,84,000, loan clears 17 months early |
An extra ₹5,000 a month — about 20% of the EMI — removes roughly ₹1.4 lakh of interest and more than a year of repayment.
What your result means
Interest as a share of the loan is the cleanest measure of cost. Below 30% is efficient; above 50% suggests the tenure is longer than it needs to be.
The year-by-year table shows why prepaying early matters so much more than prepaying late. In year one most of each payment is interest; by the final year almost all of it is principal.
The 80E benefit reduces the effective cost, but only while you are paying tax and only for eight years from the start of repayment. It is a reason to keep the loan running rather than to take a larger one.
Important considerations
- Most education loans allow prepayment without penalty. Confirm this in the sanction letter before planning around it.
- When you prepay, ask the bank to reduce the tenure rather than the EMI. Reducing tenure saves far more interest.
- Floating rates move with the bank's benchmark. A one percentage point rise on a ₹15 lakh loan adds roughly ₹90,000 over seven years.
- The Section 80E deduction runs for eight years from the start of repayment or until the interest is fully paid, whichever is earlier. It cannot be carried beyond that.
- Where a parent is the co-applicant and pays the EMI, the 80E deduction can be claimed by whoever actually pays the interest.
Limitations of this tool
- It assumes a fixed interest rate for the whole tenure. Most education loans in India are floating.
- It does not model the moratorium period — use the affordability calculator for interest accruing during study.
- Processing fees, insurance premiums bundled with the loan and documentation charges are not included.
- The 80E estimate assumes a constant marginal tax rate throughout the repayment period.
Frequently asked questions
How much interest will I pay on an education loan?
Typically 30–50% of the amount borrowed over a seven-to-ten-year tenure at Indian education loan rates. The exact figure depends on rate and tenure — enter yours above to see it.
Is it better to prepay or invest the surplus?
Compare the loan rate against the after-tax return you can reliably earn. At 10.5% interest with an 80E deduction, the effective cost is roughly 7–8% for a taxpayer in the 30% bracket. Beating that reliably is not easy, which usually favours prepayment.
Should I reduce the EMI or the tenure when I prepay?
Reduce the tenure. Keeping the EMI the same and shortening the loan saves considerably more interest than lowering the EMI over the original term.
Does Section 80E have a limit?
There is no cap on the interest amount that can be deducted, but the deduction is available only for eight years from the start of repayment, and only for interest — never for principal.
