Do you know how home loan EMI is calculated ? Its not just about Home loan , it can be any loan EMI . In this post we will learn how do we calculate monthly EMI for home Loan and how increasing Tenure does not help much after a certain point. A lot of people do not know that increasing the tenure only leads to increase in Interest amount payable and nothing else . The decrease in EMI is not proportional to the increase in Loan tenure . In Housing Finance , Equated Monthly Installments (EMI) refers to the monthly payment towards interest and principal made by a borrower to a lender. EMI is calculated using a formula that considers .

- Loan Amount
- Interest Rate
- Loan Period

**Where,**

L = Loan amount

i = Interest Rate (rate per annum divided by 12)

^ = to the power of

N = loan period in months

**Example **

Assuming a loan of Rs 1 Lakh at 11 percent per annum , repayable in 15 years, the EMI calculation using the formula will be :

EMI = (100000 x .00916) x ((1+.00916)^180 ) / ([(1+.00916)^180] – 1)

====> 916 X (5.161846 / 4.161846)

EMI = Rs 1,136

Note at i = 11 percent / 12 = .11/12 = .00916

**Q. How much benefit we get by increasing the Tenure of the Loan. Considering a Loan of Rs 30 Lacs at 12% interest rate.**

**Ans : **I did a bit of my so called “mathematical skills” … and found out that EMI is of form

EMI(n) = C1 X C2^n / C2^n-1 , where

C1 = L * i

C2 = 1+i

So the difference in the EMI value for n+1 and n is nothing but

by a bit of caculation i got :

EMI(n) – EMI(n+1) = C1 x (C2^2n – C2^n) / (C2^2n – 1)

and when n becomes very large … and appling limit, we get

Lim C1 x (C2^2n – C2^n) / (C2^2n – 1)

-> Inf=>

Lim C1 / C2^n

n->Infand as C2 > 1 (C2 = 1+i)

=>

Lim C1/C2^n = 0

n->Inf

Or in other words if we differentiate the EMI formula … we get a constant …

It shows and proves that the difference in EMI value is not very significant copmpared to the change in tenure and at one stage its almost of no gain to increase the tenure.

To show this argument : i would like to present an example, considering my old question:

Q. How much benefit we get by increasing the Tenure of the Loan. Considering a Loan of Rs 30 Lacs at 12% interest rate.

I am listing down the EMI value for different Tenures from 10 years to 100 years

Tenure EMI Differnce in EMI when tenure increased by 5 years

10 43041 7036

15 36005 2972

20 33032 1435

25 31596 738

30 30858 391

35 30466. 211

40 30254 115

45 30139 63

50 30076 34

55 30042 18

60 30023 10

65 30012 5

70 30007 3

75 30003 1

80 30002 0.95

85 30001.17 0.52

90 30000.64 0.29

95 30000.35 0.159

What it tells us is that it’s almost useless to extend the tenure after some time …

Manish Chauhan

Hi Rahul

I am not clear on what is your question. Please repeat it with more clarity

Dear Manish,

I got a home loan from a co-operative bank. the details are as follows:-

Loan Amount: 15 Lakhs

Tenure: 180 months

Interest Rate : 12 % (Floating rate of interest)

The things is we have been paying the EMI of 18,003 regularly, but some months back the Bank changed the Rate of Interest but did not inform us of the change & we kept on repaying at 12%. The new borrowers are charged an rate of interest of 10.25% currently.

Which we feel is cheated, as the document clearly states that we have got a loan on floating rate of interest, and we should have also been passed on the benefit of rate cute & availed rate of interest of 10.25%.

After we questioned the bank, they were caught a spot of bother.

The bank is giving us an option of closing the current loan account & giving us a fresh loan on the remaining principal amount at 10.25%.

We feel we would end up paying more in such case. They are considering the last unpaid principal amount & this will attract high interest amount as the loan will be a fresh one.

Request your guidance, as how much should be the loan amount (Principal to be paid) if we were to be charged as per floating rate policy (according to RBI rules).

To simplify, giving the actual scenario.

Loan amount = 15 Lakhs.

Rate of Interest = 12%

EMI = 18003 for 180 months.

EMI paid for last 53 months = 18003*53 = 954159

According to bank Principal left to be paid = 12,91,485

Now, they will start a new loan account with this as loan amount & the EMI for this wil be Rs. 16702.

So, we would like to know under normal Floating interest rate account what should be the EMI for the 54th month installment if the tenure remains the same. (i,e. 53 months paid at 12% ROI & next 127 months paid at 10.25%)

Please help.

Hi,

i have taken home loan of amt-13,50,000/- from SBI for 15yrs @9.55% …now this month i been paid 6,91,320/- as part disbursment, but bank say my emi is 14,300/- to be start from next month. Here is the doubt unless they paid full amt how they are calculating the emi on total loan value and how the emi comes with a value of 14,300/- i cant understand, please help me if there are some undercover rules for home loan not known to me……..

Manish Chauhan

Note that the EMI is same, but now the tenure will come down .. If you keep the low EMI, then the tenure will be still be same !

Ashish

Hi Rahul,

I have a home loan of 2500000 for 16 years at 9.75% interest rate. I want to take full benefit of tax exemption of 2 lacs on interest. So just want to know how much should I pay in the year to get the full benefit.

Thanks,

Ashish

Manish Chauhan

That calls for a seperate article ! . I suggest as of now talk to your bank loan lender. They will guide you on this

Arun

Hi,

Say, i am going to take a home loan in SBI for 30Lakhs, interest rate 10.0%. Now if i quote

1. for 360 months, the emi will be 26328

2. for 240 months, the emi will be 28951

how much will i save, if i opt for 360 months and pay 60,000 as part payment every year?

thanks

Arun

Manish Chauhan

In that case it would be much less than 240 months !

arun

ya thank you !!!!

Hi Manish,

I have taken a loan from LICHFL amounting 15 lacs out of which they have disbursed around 6 lacs.

This month they sent message of EMI due on 10th July for Rs. 13537. Ideally this amount of EMI is applicable only after 100 % disbursement.

They say you have to options i.e. pay as per disbursement or start the full EMI right from the beginning.

I don’t understand what to do. Please throw some light over this and guide.

Thanks

Bank provides 2 options :

1.pay as per disbursement : It means you need to pay interest only for disbursed amount until full amount get disbursed .After full amount disbursed ,Full EMI will start .

2.start the full EMI right from the beginning:

From 1st disbursement onward start paying full EMI .Initially Principle component will be more and interest component will be less in EMI .

If you have money to pay ,it is good to go with 2nd option because less outstanding amount will cause less interest to pay.

Manish Chauhan

Hi badrinath

It’s not so straight forward. Ask bank on this and they shall be able to help you on this

Manish Chauhan

Hi Neil

Your cases is a bit complex and I think we are not the right people to comment on it.

My suggestion would be hire someone who is professional in this area and consult them

Dear Manish,

I had taken home loan of Rs 21 L from LICHFL for 20 yrs in July 2009. For only about four months the rate was 8.75% and then they increased to 12%, its continued so till now. I paid EMI of 22007. Now I have savings and want to return the loan ASAP. Is it a good strategy if I pay RS 10 Lakhs now and then the rest (My o/s loan is 19,40,000) after another three months from our savings (my, husband and daughter). Some people say it was useful had you paid in small amounts from the beginning. Now its not very useful to pay, and that we should invest the amount elsewhere. Would like to know your opinion.

Thanks,

Anju

Manish Chauhan

You can surely pay a big chunk . Its just a start and will help you .. make it

Raj

You need to give application to wave off penalty for pre-payment in case of LICHFL else they may charge for this prepayment .

There is another condition which LICHFL has ,you can’t do pre-payment for first 6 months .Pls cross verify with LICHFL before paying .Clear all penalty clauses related doubts .

varun taneja

Dear Manish,

You need to be thanked for the work you are doing , I regularly read your comments and the way you answer all the queries is commendable . now coming to my query , i had taken a home loan for Rs 30 lacs ( under construction flat , payment goes based on amt disbursed) at 10.25% interest rate for 20 years from x bank , now i am transferring this loan to Y bank at 10.1% interest rate and was also thinking of reducing the tenure from 20 years to 10 /12 years , what do u suggest . thanks

Manish Chauhan

Varun

First thing you can do is approach the existing bank and ask for the interest rate change if they allow . For change of tenure, the only option is to increase the EMI amount, you can do that if you can afford that !

Shyam Ramani

Hi,

I have taken loan of 19,30,000 at 10.5 % variable rate of interest for the period of 20 years. The first part disbursement of the loan was for amount 13,00,000 (13 Lacs) done in Dec 2012. After two month of disbursement (i.e. in Feb) the rate of interest was reduced to 10.25%, and again in Sep 2013 it was increased to 11.00%. I had signed an agreement for reduced rate of interest at 10.25% from Dec 2013. The remaining amount of the loan (i.e. 6,30,000) will be disburse in Feb 2014. Kindly let me know, how to calculate the tenure after full disbursement and also if the rate of interest changes later on.

Manish Chauhan

Shyam

Why do you want to calculate it, you can get the revised tenure info from your bank itself !

Thanks for the detailed explaination on home loan. I don’t have home loan but in future this information is going to help me a lot. Thanks a lot!!

Good to hear that, you are slowing building your personal finance muscles 🙂

Deena

Hi Manish,

I have taken a home loan from ICICI bank “EMI Under Construction”, So far I have got two disbursements and two more disbursements are pending. When I got the sanction letter of home loan the interest rate was “10.5”, I had to pay EMI say “x” for 20 years. So far I have paid EMI for 9 months. Now, the interest rate has been increased to “10.75” and I was informed that still I have to pay EMI for 20 years and 4 months. I understood that “EMI under construction” doesn’t increase the EMI amount instead the tenure. But I am shocked that 0.25 increase in interest rate costs me so much i.e. increase in tenure means obviously I have to pay 12 months EMI extra?

Could you please throw some lights on this?

I am really confused about this loan and its traps

Thanks,

Deena

Manish Chauhan

Deena

They are NOT Wrong . A small increase in interest rate can push your tenure by a big margin. You can calculate this yourself, In the EMI calculator, change interest rate number and see what tenure satisfied the same EMI amount.

But this should happen in start only , not at the end leg of the loan . Welcome to the world of Home loans !

Raj

Deena,

If you have some money to pay as re-payment ,pls pay ,it will reduce your tenure a lot .Suppose if you do prepayment of Rs.100000 ,it will reduce your tenure a lot .As said by Manish ,in starting year it makes lots of diff .Inquiry with your bank and if you have low interest generating saving use them for pre payment.
