PPF Calculator

Tax-free maturity value of a Public Provident Fund account over 15 years, or longer with 5-year extensions.

How it works

PPF interest is worked out every month on the lowest balance between the 5th and the end of the month, and credited once a year on 31 March. Depositing the whole year's amount by 5 April earns interest for all twelve months, which makes the account grow like yearly compounding on deposits made at the start of each year.

balanceₜ = (balanceₜ₋₁ + deposit) × (1 + r)
Deposit
₹500 to ₹1,50,000 each financial year
r
7.1% for July–September 2026, set quarterly
Term
15 full financial years, extendable in 5-year blocks

Worked example

₹1,50,000 deposited by 5 April every year for 15 years at 7.1%.

  1. 1Year 1: 1,50,000 × 1.071 = ₹1,60,650
  2. 2Year 2: (1,60,650 + 1,50,000) × 1.071 = ₹3,32,706
  3. 3Deposits over 15 years: ₹22,50,000
  4. 4Interest earned: ₹18,18,209

The account matures at ₹40,68,209, all of it tax-free.

Frequently asked questions

Is PPF tax-free?

Yes, it is EEE: deposits qualify for the 80C deduction under the old regime, and the interest and the maturity amount are tax-free under both regimes. Under the new regime you lose only the deduction on deposits.

What happens after 15 years?

You can close the account and take the money, or extend it in blocks of 5 years, as many times as you like. To keep depositing, apply to the bank or post office within a year of maturity; without that, the balance simply keeps earning interest and you can withdraw once a year.

Can I withdraw before 15 years?

Partial withdrawals are allowed from the 7th financial year, up to half the balance at the end of the 4th year before, or of the previous year, whichever is lower. Loans against the balance are possible from the 3rd to the 6th year.

Why deposit before 5 April?

Interest for each month is paid on the lowest balance between the 5th and the month-end. Money that arrives after the 5th misses that month's interest, so a lump sum in the first days of April earns the most.
