PPF Calculator

PPF calculator for the Public Provident Fund

The Public Provident Fund (PPF) is a long-term savings scheme backed by the Government of India. You deposit between ₹500 and ₹1,50,000 each financial year for 15 years, earn a government-set rate of interest that compounds yearly, and everything you withdraw at maturity is tax-free. This PPF calculator shows the maturity value, the total interest and the balance at the end of every year.

You can choose whether you deposit by 5 April (so the money earns interest for the full year) or at the end of the year, and you can model 5-year extensions after maturity — with fresh deposits or simply letting the balance keep earning interest. The yearly table can be downloaded as CSV for your records.

The calculator starts at 7.1%, a rate PPF has paid for many quarters since April 2020, but the Ministry of Finance reviews it every quarter, so enter the current rate. Because future rates can change, the result is an estimate rather than financial advice.

How to use the PPF Calculator

1. Enter your Yearly investment. Anything below ₹500 or above ₹1,50,000 is flagged and capped to the legal limit.
2. Check the Interest rate (p.a.) and update it to the rate announced for the current quarter.
3. Choose when you deposit: By 5 April for the full year’s interest, or End of year.
4. Optionally choose an Extension after 15 years and whether you Keep depositing or make No deposits during it.
5. Read the maturity value, total invested and tax-free interest, then review or download the year-by-year table.

How PPF interest is calculated

PPF interest is worked out every month on the lowest balance between the 5th and the last day of the month, and the total for the year is credited on 31 March, so it compounds once a year. A deposit made on or before 5 April therefore earns interest for all twelve months; one made at the end of the year earns almost nothing until the next year.

With a deposit D at the start of every year, a rate r and n years, the maturity value is FV = D × [((1 + r)n − 1) ÷ r] × (1 + r). For year-end deposits drop the final (1 + r).

Example: ₹1,50,000 deposited by 5 April every year for 15 years at 7.1%: FV = 1,50,000 × [(1.071¹⁵ − 1) ÷ 0.071] × 1.071 ≈ ₹40,68,209. You invest ₹22,50,000 and earn ₹18,18,209 of tax-free interest. Depositing the same amount at the end of each year gives only about ₹37,98,515 — timing alone is worth roughly ₹2.7 lakh.

Extending PPF after 15 years

On maturity you can close the account or extend it in blocks of five years, as many times as you like:

• With contributions: submit the extension form within one year of maturity and keep depositing. ₹1,50,000 a year for 20 years at 7.1% grows to about ₹66,58,288.
• Without contributions: if you do nothing, the account continues without new deposits and keeps earning interest. Stopping deposits after year 15 still gives about ₹57,32,587 after 20 years.
• Extensions of 25 years with deposits throughout cross ₹1 crore at 7.1% (about ₹1,03,08,015).

PPF tax benefits and rules (EEE)

• EEE status: deposits qualify for a deduction of up to ₹1,50,000 a year under the old tax regime (the familiar Section 80C limit), the interest is tax-free, and the maturity amount is tax-free. Under the new tax regime the deposit deduction is not available, but interest and maturity stay tax-free.
• Liquidity: loans are available from the third to the sixth financial year, and partial withdrawals are allowed from the seventh year within set limits.
• One account per person: the ₹1,50,000 limit covers your own account plus any account you run for a minor.
• Compare PPF with a bank fixed deposit (taxable interest) or a market-linked SIP, and check what the maturity is worth after rising prices with the inflation calculator.
