What is the PPF maturity amount on Rs 1.5 lakh a year for 15 years?

PPF pays less than equity but it is sovereign-backed and the maturity is exempt from tax entirely, which changes the comparison more than the headline rate suggests.

Depositing the full Rs 1,50,000 in PPF every year for 15 years at 7.1% matures at about Rs 40,68,209. You contribute Rs 22,50,000 of your own money, so roughly Rs 18,18,209 is interest — and because PPF is exempt-exempt-exempt, none of it is taxed. For a 30% bracket taxpayer, that tax-free 7.1% is equivalent to a taxable fixed deposit paying about 10.1%.

What the extension blocks are worth

Total tenure	Total deposited	Maturity value	Interest share
15 years	22,50,000	Rs 40,68,209	45%
20 years	30,00,000	Rs 66,58,288	55%
25 years	37,50,000	Rs 1,03,08,015	64%
30 years	45,00,000	Rs 1,54,50,911	71%

The rate is not fixed for 15 years. The government resets the PPF rate every quarter; 7.1% has held for several years but the figures above assume it continues, which is an assumption, not a guarantee. A 0.5% lower average rate would reduce the 15-year maturity by roughly Rs 1,71,729.

Frequently asked

Is PPF interest really tax free?

Yes. PPF is in the exempt-exempt-exempt category: the deposit qualifies for 80C under the old regime, the interest credited each year is exempt, and the maturity amount is exempt. There is no TDS and nothing to declare as income. It is one of only a handful of Indian instruments where the entire chain is untaxed.

What happens after 15 years?

You can withdraw everything tax free, or extend in blocks of five years — with fresh contributions if you submit Form H within a year of maturity, or without them if you do nothing, in which case the balance keeps earning interest. Extending without contributions is the most under-used feature of PPF: at 7.1%, Rs 40,68,209 left alone for another five years grows to about Rs 57,32,587.

Does the deposit date within the year matter?

Considerably. PPF interest is calculated on the lowest balance between the 5th and the last day of each month, so a lump sum deposited before 5 April earns a full year of interest while the same amount deposited on 31 March earns none. Over 15 years, always depositing in early April rather than late March is worth well over a lakh.

Is PPF better than an equity SIP?

They answer different questions. Over 15 years, Rs 1.5 lakh a year in PPF at 7.1% gives about Rs 40,68,209 tax free, while the same Rs 12,500 a month in an equity SIP at 12% gives about Rs 63,07,200 before tax. Equity should win over long horizons but can fall 30% in a year; PPF cannot fall at all. Most Indian portfolios use PPF as the debt anchor and equity for growth, not one instead of the other.
