Loan EMI Calculator: Prepayments and Amortisation

SarbatDaBhalla  · September 4, 2026

Disclaimer: A planning aid, not financial advice. Actual EMIs and rates depend on your lender and your circumstances. This calculator deliberately leaves tax out — what a home or education loan deduction is worth depends on your regime, your slab and your other income. Verify with your bank, and your tax position with a chartered accountant.

The EMI is the least interesting number a loan calculator produces. What matters is what paying a little extra buys you, and whether you should be prepaying at all.

This is an estimate, not advice. Banks compute EMIs on a reducing balance the same way this calculator does, but your schedule can differ — processing fees, bundled insurance, part-month interest at disbursal and prepayment charges are not modelled. Floating rates move; this assumes yours does not. Your loan may limit prepayment or charge for it, and for closing early; those charges are not modelled either. Check your sanction letter.
Tax relief is deliberately not modelled. A home or education loan can carry deductions, but what they are worth depends on your regime, your slab, your other deductions and whether you have Indian taxable income to set them against. Those are not things a calculator can know, and a confident number here would be worth less than it looked. Every figure on this page is the loan on its own terms — work out the tax with a chartered accountant, who can see the rest of your return.
Why early prepayments matter so much. In the early years a larger share of each EMI is interest and the principal moves slowly. A rupee prepaid early stops interest on that rupee for every year left on the loan; the same rupee near the end stops very little.
If you are an NRI: repaying an Indian home loan from abroad has its own rules — repayment must generally come through NRE, NRO or FCNR channels, and TDS applies when you sell the property. Confirm your own position with a chartered accountant before you plan around it.

What this adds over a generic EMI calculator

  • Prepayments — what paying extra actually buys, both as money saved and as years removed.
  • Reduce the EMI or the tenure? — the same prepayment can do either, shown side by side.
  • No invented tax relief — a home or education loan can carry deductions, but what they are worth depends on your regime, your slab and your other income. Rather than guess, every figure here is the loan on its own terms.
  • Prepay or invest? — paying down a loan returns a certain amount; investing does not.

Home, car, personal and education loans use the same reducing-balance maths. The buttons change the typical amounts and tenures.
