The first step toward long-term wealth building is disciplined saving. While several savings avenues exist today, only a few combine stability, government backing, and risk-free returns. The Public Provident Fund (PPF) is one such trusted option.
A PPF account allows individuals, new earners, salaried professionals, and parents planning for their family’s future, to invest money safely while enjoying attractive interest and tax benefits.
However, calculating PPF interest and maturity amounts manually can be tricky because the scheme uses compound interest and interest rates may change over time. A PPF calculator simplifies the entire process.

Year-wise Projection
| Year | Invested Amount | Interest Earned | Total Balance |
|---|
Projection assumptions: The amount entered is the annual total. Annual mode assumes one deposit credited by 5 April; monthly mode divides that total into 12 equal deposits credited by the fifth day of each month. Interest is accrued monthly and added to the balance only at financial year-end. The selected rate stays constant throughout this illustration. The model starts at zero, excludes withdrawals and ignores the account-opening financial year. It is not an exact maturity-date or bank-statement calculation.
PPF interest uses the lowest balance between the close of the fifth day and month-end, and is credited at year-end. See the official PPF Scheme. Actual rates can change.
About the Public Provident Fund (PPF)
What is PPF?
The Public Provident Fund (PPF) is a popular long-term investment scheme backed by the Government of India. Its interest rate is notified by the government and may change. This calculator illustrates growth under the assumptions above.
PPF Interest Rate
The interest rate for PPF is set by the Ministry of Finance and is reviewed quarterly. Historically, it has provided attractive returns compared to standard fixed deposits. The interest is calculated on the minimum balance between the 5th and the end of each month, and is compounded annually.
Tax deduction: check the applicable regime and year
PPF falls under the Exempt-Exempt-Exempt (EEE) tax category:
- Investment: Eligible PPF contributions can form part of the combined ₹1.5 lakh savings deduction under the old tax regime, subject to the applicable conditions. This deduction is not available under the new tax regime. Section 80C applies under the Income-tax Act, 1961; the corresponding provision is Section 123 under the Income-tax Act, 2025. See the Income Tax Department’s transition FAQs.
- Interest: The interest earned every year is completely tax-free.
- Maturity: The entire maturity corpus withdrawn at the end of the tenure is exempt from tax.
Lock-in Period & Extension Rules
PPF matures after fifteen complete financial years from the end of the financial year in which the account was opened. Upon maturity, you have the option to withdraw the entire corpus or extend the account in blocks of 5 years, either with or without making further contributions.
How Can a PPF Calculator Help You?
A PPF calculator helps you understand how your investment grows over time. Since PPF interest is calculated monthly but credited annually, manual calculations can become complicated.
Here’s how the calculator helps:
✔ Tracks Growth Accurately
PPF interest rates are reviewed quarterly by the government. The calculator keeps track of expected returns and maturity values, helping you stay informed.
✔ Saves Time and Prevents Errors
The tool accrues interest by month and credits it annually, using the deposit-timing assumptions stated above.
✔ Compares Annual and Monthly Deposit Timing
Choose annual or monthly deposit timing for the same annual total. Both modes show a year-wise table; the tool does not provide a month-by-month statement.
✔ Ideal for Long-Term Planning
PPF matures after fifteen complete financial years from the end of the account-opening financial year. Extension is available under the scheme rules. A calculator helps you estimate your wealth at maturity based on your yearly or monthly contributions.
Formula Used for Calculating PPF
PPF maturity is calculated using the standard compound interest formula:
F = P × (1 + i) × [((1 + i)ⁿ − 1) / i]
This annual-deposit illustration assumes each deposit earns a full year of interest, with the same rate throughout. For end-of-year deposits, omit the (1 + i) factor. Where:
- F = Maturity value
- P = Annual contribution
- i = Annual interest rate as a decimal (7.1% = 0.071)
- n = Total number of years
Example
If someone contributes ₹1,50,000 per year for 15 years at an interest rate of 7.1%, with each annual deposit credited by 5 April and no withdrawals, the illustrated balance after 15 full financial years is approximately:
₹40,68,209
This includes ₹22,50,000 in deposits and approximately ₹18,18,209 in interest. It assumes a constant rate and excludes the account-opening financial year; actual maturity depends on opening and deposit dates and future rates.

The calculator automatically computes these values for the full 15-year tenure (and extended periods, if applicable).

How to Use the Paisaseekho PPF Calculator
The tool is simple and user-friendly. Just enter:
- Investment tenure (in years)
- Annual contribution total, in rupees
- Interest rate
- Deposit timing , monthly or yearly
Once the details are added, the calculator displays your total maturity amount instantly.
Important Note
If the contribution is deposited on 1st April, the interest will be calculated based on the financial year. Interest rates may be affected by inflation or quarterly government revisions.
Advantages of Using a PPF Calculator
Here are the key benefits:
✔ Clear Insight into Expected Returns
You can compare illustrative outcomes. Future notified rates and actual deposit dates can change the interest earned.
✔ Helps You Save Tax
The calculator estimates growth, not tax savings. A contribution does not automatically qualify for a deduction; check the regime, year and conditions described above.
✔ Helps Select the Right Investment Tenure
Many find it hard to decide whether to continue investing after 15 years , the calculator helps you make informed decisions.
✔ Estimates Total Annual Contribution
Plan how much you should deposit each month or year to reach your goals.
✔ Compares Annual and Monthly Deposit Timing
The tool assumes the same annual total each year. Monthly mode splits it into twelve equal deposits; it does not model changing contributions or withdrawals.
FAQs
1. Can I transfer my PPF account to another branch or post office?
Yes. PPF accounts can be transferred across bank branches, post offices, and even between banks and post offices.
2. How much interest can I earn on my PPF account?
The default 7.1% per annum is an illustrative input, not a promise of future returns. Check the government’s notification for the relevant quarter and update the input as needed. The tool holds one rate constant across the projection.
3. When does my PPF investment mature?
PPF matures after fifteen complete financial years from the end of the account-opening financial year. The scheme provides extension options. This calculator does not take an opening date, so it does not calculate your exact maturity date.
