The Public Provident Fund is a government-backed, tax-advantaged long-term savings scheme with a 15-year lock-in (extendable in blocks of 5 years) and interest that compounds annually. This calculator projects your maturity value.
How to Use This Calculator
- Enter your planned annual PPF contribution (up to the scheme's annual ceiling).
- Enter the number of years you plan to invest (minimum 15 for full maturity).
- Confirm the current PPF interest rate (admin-configured, editable).
- View your projected maturity value and total interest earned.
How the Calculation Works
PPF compounds annually: Balance = Σ [Contribution × (1 + Rate)^(remaining years)] across each year's contribution, using the government-declared PPF interest rate for the relevant period.
Worked Example
See the live calculator above for a year-wise projection — the exact maturity value depends on the PPF interest rate currently configured in settings, since the government revises this rate quarterly.
Who Should Use This
Long-term, risk-averse savers looking for a government-backed, tax-advantaged option as part of retirement or long-term goal planning.
Important Considerations
The PPF interest rate is revised quarterly by the Ministry of Finance and is not fixed — this calculator uses a rate configured in admin settings that should be kept current. Withdrawal rules, the annual contribution ceiling, and tax treatment can also change by notification.
Common Mistakes
Assuming the current interest rate will stay constant for the full 15-year (or longer) tenure is unrealistic — PPF rates move with government bond yields over time, so treat any long-range projection as indicative only.
