PPF Calculator
Work out the maturity value and interest on your Public Provident Fund account, including 5-year extensions.
For general information only, not financial or tax advice. Actual EMIs, returns and tax depend on your lender, bank or fund and the latest rules, so confirm before you decide.
What your result means
PPF is a government-backed savings scheme with a 15-year lock-in. The calculator shows what your account could hold at the end of your chosen tenure.
| Result | What it tells you |
|---|---|
| Maturity value | Your estimated PPF balance at the end of the tenure. Under current rules, all of it is tax-free. |
| Total invested | Your yearly deposit × the number of years. |
| Interest earned | Maturity value minus total invested. |
| Bar | How much of the maturity value is your money and how much is interest. |
| Year table | Total invested so far and the balance at the end of each year. |
The PPF rate is set by the government every quarter, so the real maturity value will change if the rate changes. The calculator assumes one rate for the whole period.
How PPF interest is calculated
The calculator assumes you deposit once at the start of each year. Interest is then added once a year, on the full balance:
Balance = (balance + deposit) × (1 + r ÷ 100), repeated every year.
- Deposit: what you put in each year, from ₹500 to ₹1,50,000.
- r: the PPF interest rate a year. It is 7.1% for October to December 2026.
- Balance: starts at zero and grows each year with your deposit and interest.
In the real account, interest is worked out every month on the lowest balance between the 5th and the last day of the month, and added to your account at the end of the financial year (31 March). If you deposit by 5 April each year, the real result is very close to the calculator’s.
How to use the PPF calculator
- Enter your yearly deposit, from ₹500 to ₹1,50,000. The default is ₹1,50,000.
- Enter the interest rate. The default is 7.1%.
- Choose the tenure: 15 years, or 20, 25 or 30 years if you plan to extend in 5-year blocks.
- Read the maturity value, total invested and interest earned, and check the year table. Results update as you type.
Worked example
Kavita deposits the full ₹1,50,000 at the start of every year for 15 years at 7.1%.
- Year 1: (0 + 1,50,000) × 1.071 = ₹1,60,650.
- Year 2: (1,60,650 + 1,50,000) × 1.071 = ₹3,32,706.
- The same step repeats each year. After year 5 the balance is ₹9,25,701, and after year 10 it is ₹22,30,124.
- After year 15, the maturity value is ₹40,68,209.
- Total invested: 1,50,000 × 15 = ₹22,50,000.
- Interest earned: ₹40,68,209 − ₹22,50,000 = ₹18,18,209.
If Kavita extends her account and keeps depositing ₹1,50,000 a year:
| Tenure | Total invested | Maturity value | Interest earned |
|---|---|---|---|
| 15 years | ₹22,50,000 | ₹40,68,209 | ₹18,18,209 |
| 20 years | ₹30,00,000 | ₹66,58,288 | ₹36,58,288 |
| 25 years | ₹37,50,000 | ₹1,03,08,015 | ₹65,58,015 |
| 30 years | ₹45,00,000 | ₹1,54,50,911 | ₹1,09,50,911 |
Each 5-year extension adds far more interest than the one before. By year 30, interest is more than double what she put in.
If you cannot deposit the full ₹1.5 lakh
You do not need to deposit the maximum. Any amount from ₹500 a year works. Here is what smaller yearly deposits could grow to over 15 years at 7.1%:
| Yearly deposit | Total invested | Maturity value |
|---|---|---|
| ₹500 (the minimum) | ₹7,500 | ₹13,561 |
| ₹12,000 (₹1,000 a month) | ₹1,80,000 | ₹3,25,457 |
| ₹50,000 | ₹7,50,000 | ₹13,56,070 |
| ₹1,00,000 | ₹15,00,000 | ₹27,12,139 |
| ₹1,50,000 | ₹22,50,000 | ₹40,68,209 |
The ₹12,000 row assumes the whole amount goes in by 5 April. If you pay ₹1,000 each month instead, you earn a little less, because later deposits earn interest for fewer months. You must deposit at least ₹500 every financial year, or the account becomes inactive until you pay a small penalty and the missed deposits.
PPF rules worth knowing
- Lock-in: the account matures after 15 full financial years, counted from the end of the year you opened it.
- Extension: after maturity, you can extend in blocks of 5 years with new deposits, or simply leave the account running without deposits for as long as you like. Either way it keeps earning the current rate.
- Deposit limits: at least ₹500 and at most ₹1,50,000 in a financial year. Any amount above ₹1,50,000 earns no interest.
- Deposit timing: deposit by the 5th of a month to earn interest for that month. A yearly deposit by 5 April earns interest for the full year.
- Loans: you can take a loan against your balance from the third to the sixth financial year.
- Withdrawals: partial withdrawals are allowed once a year from the seventh financial year.
- Tax: PPF has EEE status. Interest and the maturity amount are tax-free. Deposits count for the 80C deduction only if you choose the old tax regime.
You can open a PPF account at a post office or at authorised banks. One person can hold only one PPF account in their own name.
PPF vs other small savings schemes (October to December 2026)
The government sets all small savings rates together each quarter. For October to December 2026 it left every rate unchanged. Here is how PPF compares with the schemes people most often weigh it against:
| Scheme | Rate a year | Lock-in | Tax on interest |
|---|---|---|---|
| PPF | 7.1% | 15 years (partial withdrawal from year 7) | Tax-free |
| Post Office 5-year Time Deposit | 7.5% | 5 years | Taxable |
| Senior Citizens Savings Scheme (60+) | 8.2% | 5 years | Taxable |
| Post Office RD (5 years) | 6.7% | 5 years (closure allowed after 3) | Taxable |
The headline rate flatters the taxable options. In the 30% slab, a taxable 7.5% leaves you about 5.2% after tax, while PPF’s 7.1% stays 7.1%. In the 5% slab or below, the Time Deposit pays more. Check your slab with the income tax calculator, and see the RD calculator for monthly saving.
Limitations
- Rate changes: the PPF rate is reviewed every quarter, and the calculator uses one rate for the whole tenure.
- Deposit timing: deposits made after 5 April, or in instalments through the year, earn less than shown.
- Same deposit each year: the calculator assumes the same deposit every year.
- Exact dates: the real lock-in runs on financial years, so the actual maturity date can be a little more than 15 calendar years after you open the account.
- No inflation: the maturity value is in future rupees, so it will buy less than the same amount today.
Use the result to plan. Your post office or bank passbook and yearly statement show your real PPF balance.

FAQ
PPF Calculator FAQs
How is PPF interest calculated?
PPF interest is calculated every month on the lowest balance between the 5th and the last day of the month, and added to your account once a year on 31 March. The calculator assumes one deposit at the start of each year, compounded yearly. ₹1,50,000 a year at 7.1% for 15 years grows to ₹40,68,209.
What is the current PPF interest rate?
The PPF interest rate is 7.1% a year for October to December 2026. The Finance Ministry kept all small savings rates unchanged in its 30 September 2026 review, and PPF has been at 7.1% since April 2020. Rates are reviewed every quarter, and any change applies to your whole PPF balance from that quarter, old deposits included.
How much will I get after 15 years in PPF?
If you deposit ₹1,50,000 at the start of every year for 15 years at 7.1%, you will get about ₹40,68,209. You invest ₹22,50,000 and earn ₹18,18,209 of interest, all tax-free. If the rate changes, the amount changes too. Depositing later in the year, after 5 April, gives a slightly lower amount.
Can I extend PPF after 15 years?
Yes, you can extend PPF after 15 years in blocks of 5 years, as many times as you like. You can extend with new deposits or without them. To keep depositing, you must apply for the extension within one year of maturity. Extending for 5 more years at ₹1,50,000 a year takes the maturity to about ₹66,58,288 at 7.1%.
Is PPF tax-free?
Yes, PPF has EEE status. Interest earned is tax-free and the maturity amount is tax-free. Deposits of up to ₹1,50,000 a year also qualify for the 80C deduction, but only if you choose the old tax regime. Under the new regime, which is the default, there is no deduction for PPF deposits, though interest and maturity stay tax-free.
When should I deposit in PPF?
Deposit in PPF by 5 April each year to earn interest on the full amount for the whole year. If you pay monthly, deposit by the 5th of each month, because interest is worked out on the lowest balance between the 5th and the month end. A deposit made on the 6th earns no interest for that month.
Can I withdraw PPF early?
Yes, partly. You can make one partial withdrawal a year from the seventh financial year, up to a limit linked to your past balance. You can take a loan against the balance from the third financial year. Full early closure is allowed only after 5 years and only for set reasons, such as serious illness or higher education, with a small interest cut.
PPF vs SIP: which is better?
PPF gives a fixed, tax-free, government-backed return with a 15-year lock-in. A mutual fund SIP can grow more over long periods but has no guaranteed return and can lose value. Many people use PPF for the safe part of their savings and a SIP for growth. Compare both with our SIP calculator.
