How PPF interest is Calculated (With Calculator)

There is a great confusion among investors on how PPF interest is calculated ? Just because a lot of investors don’t know this , they have questions like “what is the best time to invest in PPF to get maximum interest” or “Should they invest in lump sum or monthly?” . Once you know the procedure and exact ppf interest calculation method, life will be easy. Let me explain with examples how its done and also give you a ppf interest calculator in a excel sheet format at the end.

To explain in one line – “PPF interest is calculated monthly on the lowest balance between the end of the 5th day and last day of month, however the total interest in the year is added back to PPF only at the year-end” 

Excerpts from Official PPF page

8. Interest – Interest at the rate , notified by the Central Government in official gazette from time to time, shall be allowed for calendar month on the lowest balance at credit of an account between the close of the fifth day and the end of the month and shall be credited to the account at the end of each year

What this means is that the interest is not compounded monthly ! . While there is no ppf interest calculation formula, but the way its calculated is very simple ! . The interest earned in a year will added back to final amount only at the end of the year. Thats the only catch ! .

So lets see 3 different kind of cases where money is invested in PPF differently and see how the interest is calculated and added back to PPF account at the end of the year. We will see these 3 cases

Case 1 : Rs 60,000 deposited once on 1st Apr

Case 2 : Rs 5,000 deposited before 5th of every month

Case 3 : Case 3 : Rs 5,000 deposited after 5th of every month

The following examples give all the 3 cases examples assuming investment of Rs 60,000  in a year , but invested differently. I have taken interest at 8.6% per annum . Recently the PPF interest rate was increased to 8.6% and the limit was raised to Rs 1,00,000 and its now applicable from Dec 1, 2011 . So if you have  invested Rs 70,000 earlier in this year , you can still invest Rs 30,000 more in your PPF account.

Note : Interest assumed is 8.6% for all the 12 months. However in reality it might happen that it may change in between for some months due to changes from govt.

Some Important Points on PPF Interest Calculation

  • If you are investing in PPF on monthly or several times a year, before 5th or after 5th will not matter a lot , it would be just few hundred rupees.
  • If you are investing your money in lump sum on yearly basis, it would be better if you can invest before the 5th of April, this will make sure that you earn interest on more balance for the month of Apr.
  • The interest on a particular month depends on the interest rate applicable for that month, if PPF interest rates change in between , then there might be different rate applicable from a point onwards.

    hi,
    I am not receiving the interest as stated. SBI credits only 6.25% and 6.5% pa. I do yearly deposit in the month of Jan or Feb. What ever is the amount before March 31 of previous year along with interest, I get interest of only 6.25 and never 7%. Is there a way out?

    Hi Manish,

    Thanks for your valuable input. It is really helpful. I have 2 queries… I opened a PPF account on 5th April’2014 in SBI bank with a initial deposit of Rs.500….Then during 5th Nov’2014 i have deposited 1,20,000…. Also I have made a deposit of 13000 during 20Mar’2014….My Query is
    1. Whether the last installment 13000 will be accounted for 2014-2015 or else it will be accounted for 2014-2015.
    2. If its true should i have to invest only 137000 on 4th-April’2015 as one time or else can i invest fresh 150000 on 4th April’2015.
    3. Since i opened my account on 5th April’2014…..whether that 1 day will be counted for 2013-2014…

    Kindly suggest ASAP.
    Thanks,
    Subash

    I got interest on PPF acount credited in my account on 31 March 2013(from my Account statement), So i will declare it in ITR of Assessment year 2013-2014, given the fact that Previous year in which this interest was credited is 2012-2013(1 April 2012-31March 2013) ?

    how to calculate RATE OF INTEREST of recurring deposit.

    Suppose I’m investing 2500 per month in recurring deposit account for 2 years with rate of interest 8% compounded quarterly. Now I have to find out MATURITY AMOUNT. For this i will use formula :

    ACTUAL AMOUNT (MATURITY AMOUNT) = PRINCIPLE AMOUNT *( (1+RATE/100/4)^(4*2)-1)/(1-(1+RATE/100/4)^(-1/3))

    ACTUAL AMOUNT (MATURITY AMOUNT) = PRINCIPLE AMOUNT *( (1+8/100/4)^(4*2)-1)/(1-(1+8/100/4)^(-1/3))

    ACTUAL AMOUNT (MATURITY AMOUNT) = 65229/-

    ========================

    Now I want to know the FORMULA OF HOW TO CALCULATE RATE OF INTEREST.

    Suppose I’m investing 2500 per month in recurring deposit account interest compounded quarterly. My MATURITY AMOUNT IS 65229/-.

    I have a PPF account with a Post Office they refuse to accept the contribution before 1-Apr for the next FY. If I deposit a cheque on 1st Apr it wont be cleared before 5th. Is there a way to make a non-cash contribution before the 5th? If not on this occasion by having a SB account with the same post office and giving a cheque from that account expedite the process?

    • Anand

      A local cheque should get cleared within 2 days. Alternatively, you can transfer the PPF account to SBI so that online transfer can be availed.

      Is your cheque not local?

      • Arun

        Past experience says a contribution done via a local cheque shows up for debit after 7-10 days (probably because of movement delays across POs). Transferring PPF to a bank is a long term solution. I was prepared to make the contribution now also but they are not ready to accept it.
