Why PPF earns its popularity
Sovereign guarantee, EEE tax status and yearly compounding: ₹1.5 lakh invested every year for 15 years at 7.1% matures to about ₹40.7 lakh — of which roughly ₹18.2 lakh is tax-free interest. No market risk, no TDS, no tax at maturity. The trade-off is honesty itself: a 15-year lock-in and a rate the government can (and does) revise quarterly.
Getting the most from it
- Deposit by April 5th — interest counts the lowest balance between the 5th and month-end; early birds earn a full extra year's worth over the term.
- Don't overshoot ₹1.5 L: the excess sits idle — no interest, no 80C benefit.
- Year 15 isn't the end: extensions in 5-year blocks keep the tax-free compounding running — many of the largest PPF balances are 25-year accounts.
- PPF + SIP is the classic pair: guaranteed floor from PPF, market upside from SIP — our SIP calculator is linked below.
Frequently asked questions
What is the current PPF interest rate?
The Government of India sets it quarterly; it is 7.1% per annum, compounded yearly. Because the rate is reviewed every quarter, a 15-year projection at any fixed rate is an estimate — the calculator lets you change the rate to test scenarios.
How much can I invest in PPF per year?
Between ₹500 and ₹1,50,000 per financial year. Deposits beyond ₹1.5 lakh earn no interest and no tax deduction — the calculator warns you at the limit.
Why is PPF called EEE?
Exempt-Exempt-Exempt: the deposit qualifies for a Section 80C deduction, the interest is tax-free, and the maturity amount is tax-free. It's one of the very few instruments where the advertised return is the take-home return.
Can I withdraw before 15 years?
The account has a 15-year lock-in, but partial withdrawals are allowed from year 7, loans against balance from year 3, and after maturity you can extend in 5-year blocks — with or without fresh deposits.
When should I deposit for maximum interest?
Before the 5th of April (or of any month): PPF interest is calculated on the lowest balance between the 5th and month-end, so early deposits earn the full year. Depositing ₹1.5 lakh on April 1–5 is the optimal move.
