Is the PPF rate fixed for 15 years?

No. The rate the Government sets each quarter applies to the whole balance, old deposits included. The calculator uses one rate for every year, so treat its result as an estimate.

Why does a deposit by 5 April earn more?

Interest is worked out each month on the lowest balance between the 5th and the end of the month. A deposit made by 5 April counts for all 12 months; one made on 6 April misses April.

Can I withdraw from PPF before 15 years?

Partly, once a year from the seventh financial year: up to half of the balance at the end of the fourth year before, or of the year just before if that is lower.

What can I do when PPF matures?

Close the account and take the money, keep it without new deposits (it keeps earning interest), or extend it for 5 years with deposits by applying within a year of maturity.

Is PPF interest taxable?

No. The interest and the maturity amount are tax-free. Deposits reduce taxable income only under the old tax regime, within the ₹1.5 lakh a year limit shared with other items.

How to use it

Type what you deposit in each financial year, from ₹500 to ₹1,50,000.
The rate opens on the PPF rate for this quarter. Change it to see what another rate would give; the Government reviews it every quarter.
Type the years: 15, or 20, 25 and so on if you extend the account.
Pick when the money goes in: once a year by 5 April, or the same total in 12 monthly deposits made by the 5th of each month.

You get the total deposited, the interest, the maturity amount, a chart and the balance at the end of every year.

How PPF interest is worked out

Interest is worked out every month on the lowest balance between the 5th and the last day of the month, and added to the account once a year, on 31 March. Money deposited by the 5th earns interest for that month; money deposited on the 6th waits until the next month. So a deposit made by 5 April earns interest for all 12 months of the year, which is why most PPF calculators assume it. Once added, the interest earns interest in the years after.

Worked example

₹1,50,000 deposited by 5 April every year for 15 years, at 7.1% a year throughout:

Year	Deposited so far	Interest that year	Balance at year end
1	₹1,50,000	₹10,650	₹1,60,650
2	₹3,00,000	₹22,056	₹3,32,706
5	₹7,50,000	₹61,368	₹9,25,701
10	₹15,00,000	₹1,47,842	₹22,30,124
15	₹22,50,000	₹2,69,695	₹40,68,209

Year 1 earns 7.1% of ₹1,50,000 = ₹10,650. Year 2 earns 7.1% of ₹3,10,650 (the ₹1,60,650 balance plus the new ₹1,50,000) = ₹22,056. After 15 years, ₹22,50,000 of deposits has earned ₹18,18,209 of interest, for a maturity amount of ₹40,68,209. Paid as ₹12,500 by the 5th of every month instead, the same ₹1,50,000 a year gives ₹39,44,599, about ₹1.24 lakh less, because each month's deposit misses the months before it.

Rules that shape the numbers

Deposits: at least ₹500 and at most ₹1,50,000 in a financial year, in multiples of ₹50, in one go or several. The ₹1,50,000 covers all your PPF accounts together, including one you run for a minor child.
Period: the account matures 15 full financial years after the end of the year it was opened in. After that it can be kept without new deposits for as long as you like, still earning interest, or extended with deposits in blocks of 5 years by applying within a year of maturity.
Withdrawals: one a year from the seventh financial year, up to half of the balance at the end of the fourth year before, or of the year just before if that is lower.
Missed years: a year without the ₹500 minimum makes the account discontinued; it can be revived by paying the ₹500 minimum and a ₹50 fee for each missed year.
Early closure: only after five years, for a life-threatening illness, higher education or a move abroad, and the interest is then worked out at 1% less.

The rate is not fixed for 15 years. Whatever rate the Government sets applies to the whole balance from that quarter, so a single rate for every year is a simplification.

Tax

PPF interest and the maturity amount are tax-free. Under the old tax regime, deposits count towards the ₹1.5 lakh a year deduction that also covers items such as life insurance premiums; the new tax regime gives no deduction for them.
