Why PPF Compounding Looks Different From Other Schemes
The PPF Calculator uses the annuity formula F = P × ((1+r)^n − 1)/r because contributions arrive every year and the balance compounds annually. The government reviews the PPF rate quarterly, and the declared rate (recently 7.1%) is applied on the minimum balance between the 5th and the last day of each month. The compounding advantage comes from the 15-year lock-in: interest is earned on interest every single year, and there are no market fluctuations to interrupt the curve.
A useful way to read the output is the split between invested capital and interest. An annual deposit of ₹1,50,000 over 15 years puts in ₹22,50,000 of your own money; at 7.1% the calculator shows interest of about ₹18.2 lakh, so interest is roughly 45% of the final corpus. Extending another 5 years (16th to 20th year) more than doubles that interest component, which is exactly why most people keep PPF running past the 15-year mark.
The EEE Tax Advantage in Real Numbers
PPF is EEE — Exempt at investment (Section 80C), Exempt at accumulation (interest), and Exempt at maturity (corpus). For a 30% taxpayer, that makes the effective return dramatically higher than a taxable instrument. A 7.1% tax-free return is equivalent to roughly a 10% pre-tax return in the 30% slab.
The catch is the 1.5 lakh annual cap. Investors with surplus cash above that limit use FD, NPS (extra 50,000 under 80CCD(1B)), or ELSS to claim further deductions. PPF also cannot be used as an emergency fund — partial withdrawals start only in the 7th year, so its role in a portfolio is long-term, guaranteed, tax-free savings, not liquidity.
Partial Withdrawals, Loans, and Extensions
From the 7th financial year, you can withdraw up to 50% of the balance at the end of the 6th year. A loan facility against the PPF balance exists between years 3 and 6 at 1% above the declared rate. After 15 years, the account can be extended indefinitely in 5-year blocks while continuing to earn the declared rate — the most common long-term retirement strategy.
The calculator models the standard 15-year cycle. If you plan to extend, run the same annual contribution for 20 or 25 years and compare — the corpus at 25 years of ₹1.5 lakh annual deposits at 7.1% exceeds ₹1 crore, and nearly two-thirds of it is interest.
