Extra Payment Calculator

What paying a little more each month actually buys you. On a 20-year home loan an extra ₹5,000 clears it more than four years early and saves close to ₹14 lakh in interest.

Also called: pay extra on mortgage, round up my emi, additional principal payment.

₹

Type "50 lakh", "1.2 crore" or "250k", all of them parse.

%
years
Payment frequency

Paying quarterly or yearly instead of monthly changes the interest, not just the instalment.

Fewer, larger instalments means the balance sits higher for longer, so total interest rises even though each payment covers more principal.

Prepayments and extra payments

A lump sum, a standing extra amount, or both. The schedule and the saving are recomputed against them.

₹

A standing amount on top of the instalment. This is what a "round up my EMI" plan does.

₹

Leave at 0 if you are not making a lump-sum prepayment.

Fees and ongoing charges

Processing fees raise your effective rate; insurance and maintenance raise your real monthly outgo.

₹

Deducted from what you receive but charged on the full loan, so they raise your APR without changing the instalment.

₹

Not part of the loan, but part of what leaves your account each month.

Interest-only period before repayment

Months before repayment starts, and whether the interest accruing in them is capitalised. The same arithmetic covers a study-period holiday, a deferment and a payment pause.

If you do not, it is added to the loan, which is why an education loan is often larger when repayment begins than the amount that was disbursed.

Monthly instalment

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

The same reducing-balance schedule as any loan, simulated month by month with your extra amount added to every instalment. Because the extra goes entirely to principal, its effect compounds: every rupee of principal removed early is a rupee that stops accruing interest for the rest of the term, which is why a small standing extra beats a large late one.

E = P * i * (1+i)^n / ((1+i)^n - 1)
E
The equal periodic instalment (currency)
P
Principal: the amount borrowed (currency)
i
Monthly interest rate = annual rate ÷ 12 ÷ 100 (decimal)
n
Total number of monthly instalments (months)

Method and limits

What it assumes

  • Interest compounds monthly on the reducing balance.
  • The rate stays fixed for the whole term. Floating-rate loans reset periodically.
  • Processing fees, insurance and statutory charges are excluded.

What it deliberately does not model

  • Does not model rate resets on floating-rate loans. Most lenders hold the instalment steady and extend the term instead, so a rate rise can add years without changing what leaves your account each month.
  • Does not include property insurance, maintenance or association dues, or any lender fee.
  • Assumes every instalment is paid in full and on time.

Frequently asked questions

Why is my bank's EMI a few rupees different from mine?
Rounding. Lenders round the instalment and true up the final payment against the residual balance, which is why the last month of a schedule looks lopsided. A difference of one or two is normal; a difference of hundreds means a different rate, tenure or fee assumption.
Why is my EMI almost all interest in the early years?
Interest in any month is the rate times the previous balance, and the balance starts at its maximum. On a 20-year loan at 8.5% the first year is about 81% interest. The only way to change the shape of that is to attack the balance early, which is what prepayment does.
