PPF
Interest uses monthly qualifying balances and is credited annually. This projection assumes complete financial years and a constant selected rate. Actual PPF maturity includes the opening financial-year stub; this model projects 15 complete years.
Defaults verified for July–September 2026 only. October–December 2026 rates are not verified; confirm the rate on your opening date. Future rates may change.

What your numbers mean
Maturity is fully tax-free under EEE status.
₹40.68L after 15 years, with ₹18.18L in tax-free interest.
You're at the ₹1.5L PPF cap — your remaining 80C bandwidth goes elsewhere.
Consider ELSS, NPS or EPF to use the rest of the ₹1.5L 80C deduction.
Extending past 15 years adds ₹62.4L by year 25.
PPF can be extended in 5-year blocks after the initial 15-year lock.

Understand your calculation
The Public Provident Fund, or PPF, is a long-term government-backed savings product in India. Interest and maturity are tax exempt; contributions qualify for Section 80C only under the old regime. This calculator models complete financial years with annual or equal monthly contributions. Actual maturity is fifteen years from the end of the opening financial year, so the opening-year stub period is not included in this projection.
How to use the PPF Calculator
- 1
Enter the annual deposit
Deposit ₹500–₹1,50,000 per financial year, in multiples of ₹50. The upper limit includes deposits in your own account and a minor's account you operate. A contribution credited by 5 April qualifies for all twelve months of that financial year's interest.
- 2
Set the tenure
Use fifteen complete financial years for the standard projection, then twenty, twenty-five or thirty to model contribution extensions in five-year blocks. Apply for a contribution extension within one year after maturity using the scheme's prescribed form. The opening financial year is an additional stub period in a real account.
- 3
Adjust the interest rate
7.1 percent is the last rate verified here, for July–September 2026. Confirm the latest Ministry of Finance notification before investing; this model does not predict future quarterly rates.
- 4
Read the maturity
The maturity value is the corpus at the end of the chosen tenure. It is fully tax free and can be withdrawn in full at maturity or partially during the tenure subject to the partial withdrawal rules.
Worked example
₹1,50,000 a year for 15 years at 7.1%
With the full deposit made by 5 April each year, year one earns `round(1,50,000 × 0.071)` = ₹10,650, so the balance closes at ₹1,60,650. Year two earns `round((1,60,650 + 1,50,000) × 0.071)` = ₹22,056 and closes at ₹3,32,706. Repeating this for fifteen years gives ₹40,68,208 on ₹22,50,000 deposited. Spread the same amount as ₹12,500 by the fifth of every month and the maturity is ₹39,44,600; deposit it in late March each year and it's ₹37,98,514.
- Annual deposit
- ₹1,50,000
- Rate and tenure
- 7.1% for 15 financial years
- Total deposited
- ₹22,50,000
- Interest earned (deposit by 5 April)
- ₹18,18,208
- Maturity (deposit by 5 April)
- ₹40,68,208
- Maturity (monthly by the fifth)
- ₹39,44,600
- Maturity (late-March deposit)
- ₹37,98,514
Timing alone moves the maturity by about ₹2.7 lakh. Extending the same ₹1,50,000 a year to 20 years at 7.1% takes the projection to ₹66,58,287.
How it's calculated
The calculator runs one loop per complete financial year. Each year it works out interest = round((opening balance + deposit × f) × r), where r is the annual rate ÷ 100, then sets closing balance = opening balance + deposit + interest. Interest is rounded to the nearest rupee every year, and the next year's interest is calculated on that closing balance, so the growth is annual compounding.
The factor f comes from your deposit-timing choice. A deposit by 5 April uses f = 1, so it earns the full year's interest. Equal monthly deposits by the fifth use f = 6.5 ÷ 12, which is the average number of months twelve instalments sit in the account. A late-March deposit uses f = 0: it adds to the balance but earns nothing until the next April.
That's a shortcut for the real PPF rule, which charges interest month by month on the lowest balance between the close of the 5th and the end of the month, then credits it at the year end. For deposits made on the dates above, both give the same answer; for other dates, check the passbook. The rate you enter is held constant for every year, deposits continue for the whole tenure, and the opening-year stub period is ignored.
Frequently asked questions
What is the current PPF interest rate?
The rate verified here is 7.1 percent per annum for July–September 2026. October–December 2026 has not been verified. The Ministry of Finance reviews rates quarterly. Monthly qualifying balances determine interest, which is credited at the financial year end.
Is PPF really tax free?
Yes. PPF carries EEE status. The annual deposit qualifies for Section 80C deduction (up to 1.5 lakh combined with other 80C investments under the old regime), the interest accrued each year is tax free, and the maturity amount is tax free. New regime taxpayers do not get the 80C deduction but interest and maturity remain tax free.
What is the lock in period for PPF?
Fifteen years from the end of the financial year in which the account is opened. Partial withdrawals are allowed from year 7 onwards, up to 50 percent of the balance at the end of the fourth preceding year or the immediately preceding year, whichever is lower. After 15 years the account can be extended in 5 year blocks.
How much can I deposit in PPF every year?
The minimum is ₹500 and maximum ₹1,50,000 per financial year across your own account and a minor account you operate. Contributions must be multiples of ₹50. Deposits credited by the fifth qualify for that month's interest; later deposits qualify from the next month.
Should I invest in PPF or equity mutual funds?
Both, in different roles. PPF is the safe debt portion of your portfolio with sovereign backing, modest but tax free returns and a 15 year horizon. Equity mutual funds are the growth portion with higher long term returns and higher volatility. A typical balanced portfolio for a 30 year old might be 70 percent equity and 30 percent debt, with PPF making up most of the debt allocation.
Can I withdraw PPF before 15 years?
Partial withdrawal is allowed from year 7 under the rules above. Full premature closure is permitted only after 5 years and only for specific reasons, including serious illness of self or family, higher education of self or children, or change of residency status. Premature closure attracts a 1 percent interest penalty.
Can NRIs invest in PPF?
Existing PPF accounts opened when you were a resident continue to earn interest until maturity but cannot be extended after 15 years. New PPF accounts cannot be opened by NRIs.
