Personal Loan EMI Calculator

The number your EMI does not tell you

Every EMI calculator on the internet will give you the same monthly figure. Punch in the amount, the tenure and the rate, and out comes an instalment. That part is not hard and nobody is doing it wrong.

The trouble is what happens before the first instalment.

You are sanctioned five lakh. The processing fee comes out of the disbursement, so four lakh ninety thousand actually reaches your account. But your EMI was calculated on five lakh, and interest is charged on five lakh. You are paying for money you never received.

So this calculator has a fourth field the others usually skip, and it uses it to work out the effective APR. That is the rate you are truly paying once the fee is accounted for, and it is the number the Reserve Bank of India requires your lender to disclose to you before you sign anything.

The processing fee box, and what to put in it

Enter the fee as a percentage of the sanctioned amount, which is how lenders quote it. Most Indian personal loans sit somewhere between 1 and 3 percent.

Now a detail that catches people out. In India, the processing fee attracts GST at 18 percent, charged on the fee itself. So a 2 percent fee on five lakh is ₹10,000, plus ₹1,800 of GST, and ₹11,800 is what actually leaves your disbursement.

The calculator takes whatever percentage you type at face value. So you have a choice:

The 2.36 comes from multiplying 2 by 1.18. If you want the honest number, use the GST inclusive figure. It moves the effective APR on our worked example from 16.196 percent to 16.429 percent, which is not nothing.

And if your sanction letter also lists documentation or stamp charges as a flat amount, convert them to a percentage of the loan and add them in too. Everything the lender deducts belongs in that box.

Working out the EMI

The instalment itself uses the standard reducing balance formula that every Indian lender uses for a term loan:

EMI = (P × r) / [ 1 - (1 + r)^-n ]

Reducing balance means interest each month is charged on what you still owe, not on the original amount. Your EMI stays flat, but the interest portion inside it shrinks every month while the principal portion grows.

Total interest is then the EMI times the tenure, minus the principal. The fee sits outside that and is added separately into Total payments, because it is not interest and pretending otherwise would muddle both figures.

Where the effective APR comes from

This is the part worth understanding, because it is where the tool earns its keep.

The question the APR answers is not "what rate did the lender quote". It is: given that I received this much money and I am paying this much every month for this many months, what rate am I actually being charged?

So the calculator does something slightly clever. It takes your EMI, which was built on the full sanctioned amount, and asks what rate would produce that same EMI from the smaller amount you actually received. There is no neat formula for that, so it searches. It brackets the answer between 0 and 100 percent a month and halves the range a hundred times over, until the rate it is holding produces your EMI to within a ten billionth. That is more precision than any loan agreement will ever need.

Then it turns that monthly rate into an annual one by compounding it twelve times:

Effective APR = [ (1 + monthly rate)¹² - 1 ] × 100

Which brings up something you will notice immediately and should not be alarmed by.

Why the APR is above your rate even with no fee at all

Run our example with the fee set to zero. Headline rate 14 percent. Effective APR: 14.934 percent. Where did that come from?

Compounding. A 14 percent annual rate quoted for monthly instalments really means 14 divided by 12, so 1.1667 percent a month. Charge that twelve times over and it compounds to 14.934 percent across a year. The headline is what the industry calls a nominal rate, and the effective rate is what a nominal rate becomes once you account for the fact that it is applied monthly.

So the gap between your quoted 14 percent and our 16.196 percent has two separate causes, and it is worth seeing them apart:

Nobody is hiding anything in the first jump. It is arithmetic. The second jump is the one that varies between lenders and the one worth shopping on.

Five lakh over four years, with the fee in it

Lets do the whole thing. ₹5,00,000 over 48 months at 14 percent, with a 2 percent processing fee.

The monthly rate is 14 divided by 12 divided by 100, which is 0.01166667.

Follow the money through it. Five lakh is sanctioned. Ten thousand comes off as the fee, so ₹4,90,000 lands in your account. You then pay ₹13,663 every month for forty eight months, which is ₹6,55,835 handed over, and adding the fee back gives a total outlay of ₹6,65,835.

Against ₹4,90,000 received, that works out to an effective rate of 16.196 percent a year. Which is two and a bit points above the 14 percent on the brochure.

What a fee is worth in rate terms

A one time percentage sounds smaller than an annual rate, which is exactly why lenders are comfortable quoting it that way. Here is the same loan with the fee dialled up:

Roughly speaking, on a four year loan, every 1 percent of processing fee costs you about 0.63 percentage points of rate.

And that exchange rate is not fixed. It gets worse on shorter tenures, because the same one time fee is spread over fewer months. A 2 percent fee on a one year loan hurts far more than a 2 percent fee on a five year one. So if a lender offers you a shorter tenure with the same fee percentage, the fee is quietly doing more damage than it was before.

Comparing two offers, properly

Now the case that makes all of this worth the trouble. Two lenders, same five lakh, same forty eight months.

Look at what those rows disagree about. A has the lower rate, the lower EMI and the lower total outlay. B has the lower APR. Three signals point one way and one points the other.

So which is cheaper? It depends on what you are optimising for, and both answers are defensible.

If your only concern is how much cash leaves your hands in total, A wins by about two thousand rupees. But A hands you less money up front, ₹4,85,000 against B's ₹4,95,000, and the APR is the measure that notices that. APR cares about when money moves, not only how much of it. Total outlay just adds everything into one pile and ignores the timing.

The practical read: with a gap this small, the two offers are near enough identical, and you should decide on the things this table cannot see. Foreclosure charges. Whether there is a lock-in period. How quickly they disburse. Whether the fee is refundable if the loan is not sanctioned.

What you should not do is pick A because 13.5 is a smaller number than 14.5. That comparison is meaningless on its own, and it is precisely the comparison lenders would prefer you to make.

Checking us against your Key Facts Statement

Here is the good news, and not many borrowers seem to know it.

Since 1 October 2024, every regulated lender in India has to give you a Key Facts Statement before you sign, on every retail and MSME term loan. It has to be in plain language, in a standard format, and the Reserve Bank was specific about what goes in it: an annual percentage rate that includes all charges the lender levies, a computation sheet showing how that APR was arrived at, and a full amortisation schedule for the loan.

The circular also says that anything not disclosed in the KFS cannot be charged to you later without your explicit consent. And the statement has to stay valid for at least three working days, so you have time to read it and compare.

So use this calculator to get a number before you walk in, then ask for the KFS and hold the two side by side. If our APR and theirs disagree by more than a small rounding difference, one of three things is true. Either there is a charge in their calculation you have not told us about, or their tenure or rate differs from what you typed, or something is wrong. All three are worth asking about, and the KFS gives you the standing to ask.

If you want the month by month breakdown to sit next to the KFS schedule, our repayment calculator prints one.

One more time

The EMI comes from the standard reducing balance formula on your full sanctioned amount. The processing fee comes off the top, so you receive less than that.

The effective APR is what you get when you ask what rate turns the money you actually received into the payments you are actually making. On five lakh at 14 percent over four years with a 2 percent fee, that is 16.196 percent. Just under a point of the gap is monthly compounding, and about one and a quarter points is the fee.

Rule of thumb on a four year loan: each 1 percent of fee costs you roughly 0.63 points of rate, and it costs more than that on shorter tenures.

Then compare on APR, never on the headline rate, and check our number against the Key Facts Statement your lender is now obliged to hand you.

Hope this saves you from a loan that looked cheaper than it was. If your KFS says something different from what we do, we would really like to know, so please tell us.

Questions people ask

Why is the effective APR higher than the rate my bank quoted?

Two reasons stacked. A quoted annual rate applied monthly compounds to something a bit higher across a year, and the processing fee means you received less than you are paying interest on. Set the fee to zero to see how much of the gap is compounding alone.

Should I include GST in the processing fee?

If you want the number you will actually live with, yes. GST is 18 percent on the fee, so multiply the quoted fee percentage by 1.18. A 2 percent fee becomes 2.36.

Is the processing fee part of my EMI?

No. It is a one time charge, almost always deducted from the disbursement rather than added to your instalments. Your EMI is calculated on the sanctioned amount as though the fee never happened, which is exactly why the effective APR is worth working out.

Offer A has a lower rate but a higher fee. Which is cheaper?

Compare the effective APR, and also look at the total outlay. If the two disagree, as they do in the worked comparison above, the offers are close enough that foreclosure terms and lock-in periods should decide it.

Does the tenure have to be in months?

Yes, this one takes months, which is how Indian lenders quote personal loan tenures. If you have been given a term in years, multiply by 12.

Does the APR account for prepaying early?

No, it assumes you run the full tenure. Prepaying changes the effective cost, usually in your favour, though foreclosure charges eat into that. The saving is largest early in the loan.

Can I use this outside India?

The maths works anywhere. The labels say rupees and the GST note is India specific, but a processing fee deducted upfront behaves the same way in any currency, and the effective APR is calculated the same way.

A note on what rests on what. The requirement that your lender disclose an all-inclusive annual percentage rate, along with a computation sheet and an amortisation schedule, is a Reserve Bank of India mandate rather than a courtesy, and the circular below is the document to quote if a lender is reluctant. The principle that an APR must fold in fees as well as interest, and the instruction to compare APR with APR, is stated in the same terms by the Consumer Financial Protection Bureau for US borrowers, which is useful confirmation that this is a settled idea rather than a local one.
