PPF Calculator
Compare contributions, estimated interest and projected balances using your own savings assumptions.
A simplified annual contribution projection. Beginning-of-year deposits earn a full year of assumed interest; end-of-year deposits earn none in that year. Actual PPF interest uses eligible monthly balances and quarterly notified rates. The selected period is a projection horizon, not an exact maturity date; PPF maturity depends on the account-opening financial year.
Inflation is an editable planning assumption, not a forecast.

Educational projection. The assumed interest rate is held constant for illustration and may differ from the rate applicable to your account. Values exclude tax, penalties and charges. Check scheme rules or the deposit provider’s actual terms before using a projection.

PPF (Public Provident Fund) is a Government-backed long-term savings scheme. It has a 15-year maturity period, allows eligible annual contributions within the scheme limits, and earns interest at rates notified by the Government. Tax treatment depends on the applicable income-tax rules and the tax regime chosen by the taxpayer.
Benefits of a PPF Account:
- Tax Benefits:
- Eligible contributions under the old tax regime may qualify for tax deductions under Section 80C of the Income Tax Act, up to ₹1.5 lakh per financial year.
- The interest earned on the PPF balance and the maturity amount is tax-free.
- Government-backed savings:
- PPF offers government-backed savings that are safe and government-backed. Unlike stocks or mutual funds, there’s no risk of losing your capital.
- Compound Interest:
- The interest on your PPF balance is compounded annually, which helps your savings grow faster over time.
- Long-Term Investment:
- PPF is ideal for long-term goals, such as retirement planning, children’s education, or building wealth for the future.
- Loan and Withdrawal Options:
- You can avail a loan against your PPF balance after 3 years of account opening.
- Partial withdrawals are allowed after the 6th year of the account, providing liquidity in case of emergencies.
- Low Risk:
- PPF is government-backed, meaning the principal and interest are safe and secure. It’s ideal for risk-averse individuals who want a safe investment option.
- Flexibility:
- You have the option to invest in a lump sum or in instalments subject to current scheme rules.
- You can extend the tenure after 15 years if you want to continue earning tax-free interest.
- Attractive for Parents:
- PPF is an excellent choice for parents saving for their children’s education or marriage due to its long-term nature and tax benefits.
How can a PPF calculator help you?
This PPF calculator helps estimate how an account may grow over time. Small-savings interest rates are notified by the Government periodically rather than changing every month. For PPF, interest eligibility within a month depends on the applicable scheme rules and deposit timing, while the credited interest is reflected according to the scheme provisions.
A Public Provident Fund calculator is useful for comparing different annual contribution amounts and investment periods. Use the latest notified PPF interest rate in the calculator and treat the result as an estimate because future rates may differ from today’s rate.
Formula used for calculating PPF
For a constant annual deposit P, annual rate i as a decimal and n years, the end-of-year contribution model uses the formula below –
F = P [({(1+i) ^n}-1)/i]
This formula represents the following variables –
| I | Rate of interest |
| F | Maturity of PPF |
| N | Total number of years |
| P | Annual instalments |
In order to clear your concept about PPF calculation, an example has been given. This calculation becomes easier once you buy PPF calculator.
PPF Calculator Examples at 7.1%
| Annual Investment | 15-Year Total Investment | Illustrative Maturity Value* |
|---|---|---|
| ₹12,000 | ₹1,80,000 | ≈ ₹3.25 lakh |
| ₹60,000 | ₹9,00,000 | ≈ ₹16.27 lakh |
| ₹1,00,000 | ₹15,00,000 | ≈ ₹27.12 lakh |
| ₹1,50,000 | ₹22,50,000 | ≈ ₹40.68 lakh |
*Illustrative values assume the same 7.1% annual rate throughout and contribution at the beginning of each financial year. Actual maturity can differ because notified rates may change and deposit timing matters.
PPF Calculator FAQs
What is the current PPF interest rate?
The calculator currently uses 7.1% p.a. as the default assumption. PPF is part of the Government’s small-savings schemes, and the notified rate can be revised periodically, so always check the latest rate before relying on an estimate.
What is the minimum and maximum PPF deposit?
Under the PPF scheme, the annual deposit is generally subject to a minimum of ₹500 and a maximum of ₹1,50,000 per financial year.
What is the PPF maturity period?
The standard PPF tenure is 15 years. Subject to the scheme rules, the account can be extended in blocks after maturity.
Does deposit timing affect PPF interest?
Yes. Interest eligibility within a month depends on the balance considered under the PPF rules, so depositing earlier in the month can affect the interest calculation. This calculator simplifies the timing assumption for planning purposes.
Is the calculator maturity amount guaranteed?
No. The result is an illustration based on the inputs you choose. Actual maturity depends on notified interest rates over the life of the account and the timing of contributions.

PPF Calculator contribution-timing check
The formula P × ((1 + i)n − 1) ÷ i models equal deposits at the end of each year. For equal deposits at the beginning of each year, multiply that result by (1 + i). The timing choice matters, so the beginning-of-year examples should not be compared with an end-of-year formula without that adjustment.
Both models hold the rate constant and simplify actual deposit dates. They are planning illustrations, not a reproduction of monthly interest eligibility on a real account. Check the India Post savings guidance for current scheme information and compare actual transactions with your account statement.
How to read your PPF result
The calculator estimates maturity using your contribution pattern, tenure and assumed PPF rate. Actual PPF interest rates are notified periodically by the Government and can change.
Planning note: Check the latest notified PPF interest rate before making a final long-term plan.
