PPF Maturity for 15 Years: Year-by-Year Estimate
A PPF account has a 15-year maturity period, but the maturity value depends on contribution amount, timing and the interest rates notified over time.
Example with maximum annual contribution
If ₹1.5 lakh is deposited near the start of each financial year and a constant 7.1% rate is assumed for illustration, the 15-year estimated maturity is about ₹40.68 lakh.
Year-by-year illustration
| Year | Total deposit | Estimated balance |
|---|---|---|
| 1 | ₹1.50 lakh | ₹1.61 lakh |
| 5 | ₹7.50 lakh | ₹9.22 lakh |
| 10 | ₹15.00 lakh | ₹22.17 lakh |
| 15 | ₹22.50 lakh | ₹40.68 lakh |
Why timing matters
PPF interest is calculated based on eligible balances according to scheme rules. Depositing early in the financial year can improve the amount that earns interest for the year compared with depositing late.
Rate changes
PPF interest rates are not fixed for the full 15-year period. The government can revise rates periodically. A calculator using one rate is useful for understanding mechanics, but it cannot predict the official future rate path.
Extension after maturity
After maturity, PPF may be extended in blocks under applicable rules. Extension with contribution and extension without contribution have different planning effects, so check current rules before maturity year.
Use cases
PPF can support long-term conservative goals, tax-aware savings and diversification from market-linked investments. It should still be planned alongside liquidity needs because withdrawals are restricted.
