What is the PPF Calculator?
The Public Provident Fund (PPF) is a Government of India small-savings scheme whose applicable interest rate is notified periodically. This calculator estimates a maturity value from an existing balance, annual contributions, an editable planning rate, and a projection horizon. It provides an educational projection under the assumptions entered rather than an account statement or a prediction of future notified rates.
The governed default is 7.1% p.a., notified for Q3 FY 2026-27 (1 October–31 December 2026). The calculator holds the entered rate constant for illustration. Government-notified PPF rates may change in future quarters.
Eligible contributions may qualify under applicable Section 80C rules for taxpayers using a regime where the deduction is available. Any deduction depends on the taxpayer's regime, taxable income, remaining Section 80C headroom, and other deductions; it is not part of this calculator's result.
How does it work?
The calculator uses annual contributions and annual compounding for a simplified projection. At the start of each modeled year it adds the entered annual contribution to the current balance, then applies the entered annual rate. An existing balance, when entered, is included before the first modeled contribution.
For a zero opening balance, this is the future value of an annuity due: F = P × [((1 + r)^n - 1) / r] × (1 + r), where P is the annual contribution, r is the entered annual rate as a decimal, and n is the number of modeled years. The annual model does not represent the exact timing and crediting rules used in an individual PPF account.
The calculator does not model exact deposit dates or monthly balance calculations. It also does not separately model regulatory extension modes. An entered horizon longer than 15 years is only an illustrative continuation of the same annual contribution and constant-rate assumptions.
Worked example
Enter an annual contribution of ₹1,50,000, an existing balance of ₹0, a 7.1% planning rate, and a 15-year horizon. Using a constant 7.1% planning assumption, the production calculator adds each annual contribution at the start of the modeled year and projects ₹40,68,209. Total modeled contributions are ₹22,50,000, so the projected growth under these inputs is ₹18,18,209.
This result does not assume a specific deposit date, calculate an individual tax saving, or predict the PPF rates that will be notified during the 15-year period.
When to use this calculator
- 1Estimate a simple long-term projection from an existing PPF balance and annual contributions.
- 2Compare how different annual contribution assumptions change the illustrated maturity value.
- 3Explore the effect of changing the editable planning rate or projection horizon.
- 4Review a PPF projection alongside your liquidity needs, tax situation, time horizon, and other goals.
Common mistakes to avoid
- ✕Treating the entered rate as fixed for the full horizon. It is a constant planning assumption in this projection, while notified PPF rates may change in later quarters.
- ✕Reading the annual projection as an exact PPF account statement. The calculator does not reproduce monthly balance calculations, deposit dates, or account-specific credits.
- ✕Assuming a horizon beyond 15 years models a particular extension option. The calculator simply continues the same annual inputs for the selected number of years.
- ✕Treating projected growth as a personal tax saving. The calculator does not know your tax regime, taxable income, Section 80C headroom, or other deductions.
- ✕Entering contributions without checking current scheme limits, access rules, and liquidity needs against official information.
Frequently asked questions
- What PPF rate does this calculator use?
- The editable default is 7.1% p.a., notified for Q3 FY 2026-27 (1 October–31 December 2026). The calculator holds the entered rate constant for illustration. Government-notified PPF rates may change in future quarters, so verify the latest Department of Economic Affairs notification.
- Does the calculator model my actual PPF deposit dates?
- No. It uses one contribution at the start of each modeled year and annual compounding. It does not model exact deposit dates or monthly balance calculations.
- Does a longer horizon model PPF extension rules?
- No. This calculator does not separately model extension modes. A horizon longer than 15 years is only an illustrative projection that continues the same annual contribution and constant-rate assumptions.
- Does the projection include my Section 80C tax saving?
- No. Eligible contributions may qualify under applicable Section 80C rules for taxpayers using a regime where the deduction is available, but the outcome depends on personal tax circumstances. The displayed result includes only modeled contributions and growth.
- How should I interpret the result?
- Use it as a simplified scenario under the entered annual assumptions. Whether PPF fits your plan depends on your liquidity needs, tax situation, time horizon, and other goals.
