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 …

@Stock trading

Thanks a lot .. what do you think about the maths done here .. just curious

Manish

I have taken a fixed home loan of 20,00,000 for 15 years with 9.5% rate. My EMI was 22K, however i started paying 30K instead to save some interest.

Current outstanding is 17.40 Lacs,

With my calculation i will be closing the loan in next 6 years.

I have some money now around 1 Lac, Should i pay this one and save interest or invest in a mutual fund and continue as per plan to close in 6 years.

Brilliant conclusion man. Thanks for this I saw this blog today for the first time, but I will visit again

Hi Ajeet

Thanks for stopping by and reading . I am sure you will get amazing things in future too

Manish

Manish ,

U Rockz . Tihs blog makes me to re check my math skills . U r simply awsome

Amarnath

Thanks man … I am sure you are talking about the calculas part

Manish

Was just browsing through old posts of yours. Would be good if readers also browse this loan amortization schedule @ http://office.microsoft.com/en-us/excel-help/using-the-loan-amortization-and-loan-analysis-templates-HA001034640.aspx

hi manish i read this mail, i adviced my sister to take a longer duration home loan, the reason is every year she does top up of 1lac rs in principal and the difference from 20 years to 15yrs is small, she invest the small part in sip, which we book book profit and prepay the loan, we have planned to stop the loan in ten years . this way she is paying more of principal in the initial 6 years.

is it a good statergy.

Geo

I dont think so . If it was increasing the tenure from 5 to 10 yrs or 10 to 15 yrs, the reduction in EMI would be good enough , but just try to see what is the EMI reduction happenening when you increase the tenure from 20 to 25 yrs ?

For a 40 lacs loan @10% interest and tenure 20 yrs , EMI per month = 38601

However when you increase the Tenure to 25 yrs , the EMI comes to 36348 . Thats very insignificant decrease .

Manish

your work is commendable..

but you forgot to take into account time value of money.

Value of money after 30 years is going to be much less than what it is going to be after 10 years. So, repaying the loan in 30 years is much beneficial than repaying back in 10 years. ( in accordance to your stats mentioned above)

You are right when it comes to comparison for 100 years..but I dont think it applies in real world as no bank would offer you that…

cheers,

Srikar

yup

Agree with you

Manish

good this is helpfull.

Dear Manish,

First of all my sincere thanks to you for writing this blog. It really educates me a lot and helps me to lead a wealthy life.

I’ve a query to you regarding housing loan per-repayment of principal while the loan is in partial disburse sate (the loan amount is not fully disbursed).

In details:

- I booked a FLAT which is under construction

- For that, I opt for home loan from SBI (EASY HOME LOAN product)

- The load got sanctioned for 35L on Dec 2009 but the payout(disburse) of the loan amount is linked with the progress of the my flat.

- So for, I the bank disbursed 20L as my flat progressed

- The repayment(EMI) will start in one of the following cases which ever comes first.

1. on July 2011

2. after completion of my flat (i.e. once the full loan amount is disbursed)

- And I don’t need start any repayment(pre-EMI) before the EMI commences.

- But the interest will be calculated for the partial disburse amount and it’s accumulated(again, interest is applicable for the interest) in my loan account.

- From my loan account statement, I can see around 1.5L is accumulated a interest for the partial disburse.

- Meanwhile, I’ve saved around 5L from my salary and put it in a FD (in a different bank) where the interest rate is lower than the home loan interest.

My question here is:

Can I pay 5L towards my loan account now? (1.5L towards interest + 3.5L towards principle)

I asked the same question to my SBI bank manager, he confirmed about the interest part (1.5L) but he is not sure(he don’t know the T&C) about the principle part. He recommend me to not payback the principle now but after the EMI starts.

My problem is, loosing money because of,

– the interest difference between my FD and my home loan

– and the TDS for interest earned form my FD.

And I fear, if any penalty applicable for if I prepay principle(3.5L) at this stage.

Thanks!

Hi Manish,

I have taken 30,71,000 home loan from SBI for a tenure of 20 years. Interest rate is 8 % 1st year, 9% for 2nd and 3rd year and then floating. SBI has included 18 months of Moratorium period since property will be ready by then, and they will charge only interest part and not principal during this period. Now builder is demanding me to avail ADF facility with SBI. I feel that ADF is not good for me because even on face I am paying extra with Moratorium option, if I invest balance part of EMI for a period of 20 years with average 10 % yearly return that would fill the extra amount I am paying. And second advantage is that I can keep check on builder for work completion to my satisfaction. Can you please help me decide on which option to choose ADF or Moratorium period?

Prithvi

Dont go for ADF , choose pre-EMI , here is why : http://www.rediff.com/getahead/2006/jul/03loan.htm

Manish

Thanks Manish..

I”ve applied a home loan by structured EMI, Where I am paying 1st 4 EMI of Rs. 1000/- and 6th EMI as 11320.00 & nest 5 EMI as 1000.00 and 6th EMI as 11320 for this process entire 60 month paying.

Kindly provide the EMI repayment schedule with EMI, Interest Portion, Principal Protion and Outstanding Principal after EMI.

Loan Amount 100000.00

Tenure – 60 Months

Sturctured EMI – Monthly 1000.00 & Half Yearly 11320.00

Rate of Interest: 20.00%

Pls replay as per the details, if you can provid ethe schdule in Excel than better for me.

Hi,

I want know how bank calculate home loan limit of a person based on his earning power.

Thanks & regards,

mukesh

Mukesh

I am not sure on that, but it should be easy , it should be X times the yearly income , where X can range from bank to bank and is calculated based on job sector , security , past repaying capacity

Manish

I have a plan to take home loan up to 15 lacs.Right now my property is in underconstruction. Now, i want to know if i get the loan from bank during that peroid. How should i have to pay EMI if bank give a money to contractor on progress based.

Amish

the whole procedure whold be almost same as you take a new flat , where exactly are you finding the problem ?

manish

What is the procedure to find out the break-up of Principal and Interest within a Constant EMI. For Example,

Loan Amount = INR 100,000/-

EMI = Constant Amount of INR 3,145.00Per Month, for 36 Months.

Rate of Interest = 8.25%PM

Thus, from Month 1 to Month 36, the Principal Component would increase while the Interest Component would decrease.

Please let me know how the appropriation of the EMI happens, between Principal and Interest Amounts, across these 36 Months.

Thanks in advance.

NVLM

You can use this calculator : http://www.jagoinvestor.com/calculators/html/loan-amortization.html

Manish

In my Query, please read the Interest Rate as 8.25 % PA (type error – mentioned this as 8.25% PM).

Hi Manish,

I have taken a home loan of 17 lakh for 20 years of which only 9.5 lakh is disbursed as yet.Pre EMI interest is being deducted of approx Rs8k .

Can you pls recommend the best options out of below:

1. Get Pre-emi converted to full EMI (of 17k) so that prinicpal also gets reduced

2. Continue paying interest only till full loan disbursement & pay partial repayments from after some intervals to reduced liability

Thanks in advance…!

Manish

loan amount 1000000, 60 months , interest 12.25 % how to calculat education loan emi method ? i want step method to find out principle and interest

Nirmal

You can use this calculator : http://www.jagoinvestor.com/calculators/html/loan-amortization.html

Manish

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

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

EMI = Rs 1,136

reply me step method : how to calculate ( 1+.00916) ^180

what is mean ^

Nirmal

That means to the power of , you can use our calculator on EMI : http://www.jagoinvestor.com/calculators/html/loan-amortization.html

(1+0.00916)

=1.00916

^which means Number months in a year means 12*15=180.

1.00916*180

=183.0……….

That was really an eye opener

thanks

Tejkant

Good to hear that you liked it

Hi Manish – great to see the black magic maths behind the EMI, i do have a question on this though, the above formulae seem to calculate for ‘repayment type loans’ which is fine most of the time. Quite curious what would be the formalae when only the ‘interest component is being paid’ as is common in western countries, clearly the above does not suit those cases?

Thanks

Aditya

Aditya

Some maths might be needs in that case .. not aware of that right now .. may be asking it on our Q&A forum would help

Mr. Manish

I wanted to know whether the duration of the loan repayment will reduce or not if i increase the EMI.IF yes, kindly give me the benefits of doing so from the borrower’s point of view.

Selvi

Better than increasing the EMI , go for monthly prepayments .. that would be a better choice !

I am not able to understand the diffrence between EMI and MONTHLY PAYMENTS.Can u please clarify.Monthly payment how does it help

Monthly prepayments are extra payments you can do other than EMI !

Thanks for your immediate reply.To be specific to my question ,I have availed loan from Union bank of India personal loan 25 laks @ 14.25 for 8 yrs.I am paying 43785.00 emi.How do I reduce the emi.One thing is clear from your reply that I can make some extra payment to reduce the interest .

Sir ,Do u have your office in chennai.

You cant reduce the interest, you can only reduce the loan outstanding , for which you can make extra payment other than your regular EMI !

Thank u Sir.

My home loan (sbi) Rs 20,00,000. tenure 15 yrs emi Rs 19226 I pre paid Rs 3,00,000 towards principle .now i like to pay another 4,00,000 towards principle also want to reduce tenure to 10 yrs . Please give me suitable suggestion

Vasundhara

You can keep prepaying the amount , when your prepay , your EMI will be same, but the tenure will automatically come down ! . Dont worry on that. I am sure when you prepay 7 lac in total out of 20 lacs, your tenure will be below 10 lacs only . Ask your bank to give you the updated tenure now

Great work man ..Keep it up..:-D

thanks Rajiv

DEAR MANISH

Thanks for writing the mindblowing blog

My quiry is

I have purchased a under construction flat, it will be ready in next 1 yr., my construction company asking for the documents for making loan case. the EMI for which will be started after i get the possession of the flat.

1. do i have to pay the intertest on the money the construction company using for the period untile EMI start date. if yes can i pay some principle also with this interest.

2. if i have some money with me now, is it better to pay to the construction company & reduce the loan amount or to prepay this lumpsump amount to the bank after the loan case strat.

Sachin

This question is best suited for our forum : http://www.jagoinvestor.com/forum/

I have taken 12 lakh loan. The interest rate is 8.25 for the first six months and then 9.25 for the next twelve months. How will I calculate the EMI for this loan? I’d be grateful to hear your solutions please. Thanks Binu

You need to make an amortization sheet (learn about it) and then you should be able to make it on your own !

Please advice

1. shall i withdraw my pf fund to reduce my home loan as home loan intrest @ 9.8 % and PF intrest rate is 8.6 % only

2. How the home loan intrest is calculated compounded quarterly or monthly as pf intrest rate is compounded monthly basis…..

Naresh

EMI is calculated this way : http://www.jagoinvestor.com/2008/01/how-home-loan-emi-is-calculated.html

Dear Manish Ji,

Pls tell me how to calculate this figure

Thanks

((1+.00916)^180 ) / ([(1+.00916)^180] – 1)

(5.161846 / 4.161846)

EMI = Rs 1,136

You can do it in excel sheet .. just put a “=” before that and press enter .

Manish

My loan amount is 1500000 lakh, for 20 years & rate if int is 11.10

Ihave taken the loan of Rs. 8500000 for 15 years@ 9.5% in 2004. Now after 8 years, how much should I pay totally if I want clear the loan now. And is it wise to do so?

You can check your loan outstanding from the bank where you have taken the loan from . Is it wise or not, will depend on your view about the debt and your over financial situation !

Thanks for putting the calculations Manish. I am planning to transfer my home loan from one bank to another. I want to calculate how much money i am going to save before i make this decision. Can you please point me to calculations which i can do, considering i will keep prepaying some amount in loan time to time?

Right now we do not have any such kind of calculator . I will try to prepare it sometime , as of now you can pose your question here http://www.jagoinvestor.com/forum/

Check this – http://jagoinvestor.com/calculators/html/loan-amortization.html

Say i have taken a home loan with following details:

loan amount: 3000000 (thirty lakh)

interest:11%

tenure:25yrs(300 months)

Now my question is if i don’t pay any emi and I say that I will pay full amount after 300 months. What would be the amount I have to pay after 300 months

It will run into several crores . This is not how loan works .

Hi Manish, your blog is very useful.

I have my home loan in SBI with 10.25% for 20 years for loan amount of Rs. 17,60000/-

I did the calculation as per the formula given in your blog.

It says my loan amount should be 17296/-, but i am paying 17580/-

Am I missing anything in the calculations?

May be the processing fees and other charges . Take the explaination from bank !

Hi Manish,

I have two queries,

1) In my Provisional certificate the intrest expected amount written as 59000/- per anum, However in final Intrest certificate the actual amount written as 83000/- per anum, How the calculation is been done? and To whom i concern about this(The Branch or Home loan department)

2) My Rate of Intrest gets down from 10.75 to 10.50 and 10.50 to 10.25 but no change in EMI. how do bank is working on this calculations….. would they decrese my loan tenure or intermediate amount adjustable?

Loan from Bank of India.

Please guide me on same.

Hi Rohit

As its a PSU bank , I strongly suggest file a RTI and get answers from that, that will be the fastest way .

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

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 !

Manish,

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

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.

Shyam

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