What is a PPF calculator?
A PPF calculator works out how much your Public Provident Fund account will be worth at maturity. You enter the yearly deposit (or a monthly amount), the current PPF interest rate and the period – 15 years or longer with 5-year extensions – and this PPF calculator online shows the maturity amount, the total interest earned and a year-wise table of deposits, interest and balance. It follows the actual Post Office and bank rules for PPF, so the result matches what you see in your passbook when the rate stays the same.
What is PPF?
What is PPF? The Public Provident Fund is a Government of India small savings scheme under the PPF Scheme, 2019. You can open a PPF account at any post office or at authorised banks such as SBI, PNB, Bank of Baroda, ICICI and HDFC. Key rules:
- Tenure: 15 full financial years after the year of opening.
- Deposit limits: minimum ₹500 and maximum amount in PPF ₹1,50,000 per financial year (including any minor account you run as guardian). You can pay in one go or in instalments.
- Interest: set by the Government each quarter, compounded yearly and credited on 31 March.
- Tax: EEE status – deposits qualify for Section 80C (old tax regime), and interest and maturity are fully tax-free.
- Safety: backed by the Government, so PPF is risk free for capital and interest.
Current PPF interest rate (2026)
The PPF interest rate is 7.1% per annum for the July–September 2026 quarter (Q2 of FY 2026-27). The Finance Ministry kept all small savings rates unchanged for this quarter; PPF has been at 7.1% since April 2020. The rate for October–December 2026 is announced at the end of September, so check the latest notification and update the rate field if it changes.
How to use the PPF calculator
- Choose yearly or monthly deposits. Use the monthly option for a PPF calculator monthly investment plan.
- Enter the deposit – between ₹500 and ₹1.5 lakh a year (up to ₹12,500 a month).
- Keep the rate at 7.1% or enter a different rate to test scenarios.
- Pick 15 years for normal maturity, or 20, 25, 30 years to model the PPF 5-year extension with contributions.
How is PPF amount calculated? (PPF formula)
Interest is calculated every month on the lowest balance between the 5th and the last day of the month, but credited only once a year. If you deposit the full yearly amount before 5 April, the whole deposit earns interest for 12 months and the maturity follows the annuity-due formula:
F = P × [ (1 + i)n − 1 ] ÷ i × (1 + i)
- F = PPF maturity amount
- P = yearly deposit
- i = PPF interest rate ÷ 100 (0.071)
- n = number of years (15)
For monthly deposits the calculator adds interest month by month on the running balance (rate ÷ 12) and credits it at year end, exactly as the Post Office does.
PPF calculation example: ₹1.5 lakh a year for 15 years
Deposit ₹1,50,000 every year before 5 April at 7.1%: F = 1,50,000 × [(1.071)15 − 1] ÷ 0.071 × 1.071 = ₹40,68,209. You invest ₹22,50,000 and earn ₹18,18,209 as tax-free interest. With ₹1,000 a month (₹12,000 a year, deposited yearly) the PPF maturity amount is about ₹3,25,457.
PPF calculator for 15, 20 and 25 years
| Yearly deposit at 7.1% | 15 years | 20 years | 25 years |
|---|---|---|---|
| ₹50,000 | ₹13.56 lakh | ₹22.19 lakh | ₹34.36 lakh |
| ₹1,00,000 | ₹27.12 lakh | ₹44.39 lakh | ₹68.73 lakh |
| ₹1,50,000 | ₹40.68 lakh | ₹66.58 lakh | ₹1.03 crore |
PPF monthly vs yearly deposit
Depositing the full amount before 5 April earns the most interest because the money works for all 12 months. ₹12,500 a month before the 5th of each month gives a little less – about ₹39.4 lakh after 15 years instead of ₹40.68 lakh. If you pay monthly, always pay before the 5th; a deposit on the 6th earns no interest for that month.
PPF after 15 years: extension rules
At maturity you can: close the account and take the tax-free amount; extend it for 5-year blocks with contributions (submit Form 4 within one year of maturity); or keep it running without contributions, where the balance keeps earning interest. During an extension with contributions you can withdraw up to 60% of the balance at the start of that block. Pick 20, 25 or 30 years above to use this as a PPF calculator with extension.
PPF withdrawal and loan rules
- Partial withdrawal is allowed from the 7th financial year: up to 50% of the balance at the end of the 4th year before, or the end of the previous year, whichever is lower – once a year.
- Loan is available from the 3rd to the 6th year, up to 25% of the balance two years earlier.
- Premature closure is allowed after 5 years for medical treatment, higher education or change of residency, with a 1% interest cut.
PPF for minor or new born baby
A parent can open a PPF account for a minor, even a new born baby. The ₹1.5 lakh limit is combined for your own and the minor's account. For a daughter under 10, the Sukanya Samriddhi Yojana calculator is worth a look – SSY pays 8.2% now.
PPF vs SIP, NPS and mutual funds
PPF gives a guaranteed, tax-free 7.1% with zero risk. A SIP in equity mutual funds may give higher long-term returns but with market risk and tax on gains. NPS is a retirement product with partial equity exposure and an annuity requirement. Many people use PPF as the safe, debt part of their portfolio and SIPs for growth.
Extensions, deposit timing and existing balances: what to enter
What is PPF calculator and how PPF calculator works
What is PPF calculator? It is a tool that applies the PPF interest rules to your deposits. How PPF calculator works: each year it adds your deposit, calculates interest on the balance at the PPF rate and credits it at year end, for the period you choose.
PPF calculator for 5, 10, 15, 20 and 25 years
A PPF calculator for 15 years is the standard case. Choosing 20 or 25 years shows the effect of extending the account in 5-year blocks. For 5 or 10 years, the PPF calculator can only show a mid-point view, as the account cannot be closed normally before 15 years – check the year-wise table for the balance at year 5 or 10.
PPF calculator yearly, monthly and monthly vs yearly
Pick yearly or monthly deposits in the PPF calculator. Comparing monthly vs yearly, a single deposit before 5 April earns about ₹1.2 lakh more over 15 years at the maximum ₹1.5 lakh limit.
PPF calculator with existing balance
For a PPF calculator with existing balance or current balance, the table helps: find the year that matches your current balance and read forward. For an exact figure, add your current balance × (1.071)remaining years to a new projection of future deposits.
PPF calculator with step up and variable amount
PPF allows a different amount every year, up to ₹1.5 lakh. A PPF calculator with step up or variable amount gives a result between the lower and higher fixed-deposit scenarios – run both to bracket it.
PPF calculator lumpsum and one time investment
A PPF calculator one time investment is not possible in the scheme: you must deposit at least ₹500 each year to keep the account active. The yearly option is the closest to a PPF calculator lumpsum deposit.
PPF calculator India Post and banks
The rules and rate are the same whether you use a PPF calculator India Post account or a bank PPF account, because the PPF calculator government rules apply everywhere.
PPF calculator with inflation
At 6% inflation, ₹40.68 lakh after 15 years is worth about ₹17 lakh in today's money. A PPF calculator with inflation view reminds you that PPF's real return is modest but tax-free and safe.
PPF calculator vs SIP calculator and RD calculator
A PPF calculator vs SIP calculator check usually favours SIPs over 15 years, with risk. A PPF calculator vs RD calculator check favours PPF due to tax-free interest. See also the RD calculator.
Is this PPF calculator free?
Yes – it is free and online, with a year-wise table built for India. The PPF calculator comes with the current rate of interest pre-filled, so the calculation takes seconds.
PPF calculator for different amount every year
Few people deposit the same sum for 15 years. If you deposit a different amount each year, a year wise calculation is needed: add the year's deposit to the balance, then apply 7.1% interest. For example, ₹50,000 a year for years 1–5, ₹1 lakh for years 6–10 and ₹1.5 lakh for years 11–15 is ₹15 lakh invested, which grows to about ₹24.08 lakh. By comparison, a steady ₹1.5 lakh every year (₹22.5 lakh in total) grows to about ₹40.68 lakh.
PPF calculator yearly wise different amount in Excel (XLS)
To build a PPF calculator in XLS for yearly different amounts, put the year in column A and the deposit in column B. In C2 enter =(B2)*1.071 and in C3 =(C2+B3)*1.071, then copy down to year 15. Change 1.071 when the government revises the rate each quarter.
PPF calculator formula and details
The PPF calculator formula for equal yearly deposits made before 5 April is M = P × [((1 + i)n − 1) ÷ i] × (1 + i), where P is the yearly deposit, i the rate (0.071) and n the years. Key PPF details the calculator assumes: minimum ₹500 and maximum ₹1.5 lakh a year, interest compounded yearly and credited on 31 March, and a 15-year lock-in that can be extended in 5-year blocks.
Is interest in the PPF calculator quarterly?
No. The rate is announced quarterly, but the PPF calculator compounds interest yearly. Interest is worked out each month on the lowest balance between the 5th and the last day of the month, and the total is added once a year – which is why deposits made before the 5th earn more.
How to pay into a PPF account
You can pay to a PPF account by net banking or the bank's mobile app (for accounts held with a bank), by UPI or standing instruction where the bank allows it, by cash or cheque at the branch, or through India Post's IPPB app for post office accounts. Pay before the 5th of the month – ideally before 5 April – so the deposit earns interest for that month.
PPF calculator vs NPS and mutual fund
The PPF calculator shows a guaranteed, tax-free result, which is its main strength. Compared with NPS, PPF is fully tax-free and liquid after 15 years, while NPS is market-linked, gives an extra ₹50,000 deduction under Section 80CCD(1B) in the old regime and requires 40% of the corpus to buy an annuity at 60. Compared with an equity mutual fund, PPF gives lower but certain returns; equity funds have historically earned more over 15 years but can fall, and gains above ₹1.25 lakh a year are taxed at 12.5%.
Calculate PPF maturity amount after 15 years, for a minor or a new born baby
To calculate the PPF maturity amount, enter the yearly deposit and 15 years; ₹1.5 lakh a year at 7.1% matures at about ₹40.68 lakh. To see a PPF calculator after 15 years result, enter 20 or 25 years: extending with deposits of ₹1.5 lakh for one more 5-year block takes the total to about ₹66.58 lakh, while extending without deposits grows the ₹40.68 lakh to about ₹57.3 lakh. A parent can use the same PPF calculator for a minor or a new born baby – the child's account runs 15 years from opening, but deposits in the child's and the parent's own PPF accounts together count toward one ₹1.5 lakh yearly limit.
Online PPF account opening and saving your results
Most banks that offer PPF allow online PPF account opening through net banking for existing savings customers; post office accounts are opened at the branch. There is no PPF calculator download to install – bookmark this page, or use your browser's Print option to save the year-wise table as a PDF.
