PPF Calculator – Maturity Value, Exact Date and What You Can Withdraw

The Public Provident Fund (PPF) is India's government-backed, 15-year savings scheme: the rate is set by the Government every quarter, the balance is sovereign-guaranteed, and interest is tax-free. It looks simple, yet most online PPF calculators get two things wrong: they compound once a year on whatever you deposited, and they stop after 15 deposits. This calculator follows the scheme's own rules, month by month, so the maturity value and the maturity date match your passbook.

How PPF interest is really calculated

Interest is worked out every month at rate ÷ 12 on the lowest balance between the close of the 5th and the end of the month. The twelve monthly amounts are added up and credited once, on 31 March. That single rule explains why the timing of your deposit matters:

  • A deposit made on or before the 5th counts for that month. One made on the 6th waits until next month.
  • A lump sum on or before 5 April earns interest for all twelve months of the financial year.
  • The same sum paid in late March earns nothing that year, so over a full term it can cost you more than ₹2.5 lakh at the maximum deposit.
  • Monthly installments go in later on average, so they end with a smaller corpus. They still earn the same effective rate.

The "When you deposit matters" chart compares these patterns on your own numbers, and the year-by-year table lets you expand any year to see each month's lowest balance and interest.

When does a PPF account mature?

A PPF account matures after 15 complete financial years counted from the end of the year it was opened, which is 1 April of the opening FY's start year + 16. An account opened on 1 April 2027 (FY 2027-28) matures on 1 April 2043. One opened on 24 September 2026 or on 31 March 2027 (both in FY 2026-27) matures on 1 April 2042. The base term therefore spans 16 financial years, and a regular saver makes 16 deposits, not 15.

Why online PPF calculators show ₹40.68 lakh
The textbook formula P × ((1 + r)^15 − 1) / r × (1 + r) gives ₹40.68 lakh for ₹1.5 lakh a year at 7.1%. That is only the balance at the end of Year 15. With the 16th deposit and another year of interest, the real maturity value is about ₹45.18 lakh.

Loans, partial withdrawals and premature closure

PPF is a lock-in product, but it is not completely locked. From the 3rd to the 6th year you can take a loan against PPF of up to 25% of the balance two years earlier. From the 7th year you can make one partial withdrawal a year of up to 50% of the lower of two balances: the one four years earlier and the one at the end of the previous year. After five years the account can also be closed early on specified grounds such as serious illness or higher education, but interest is then recalculated at 1% below the rate. The Loans & withdrawals tab lists every limit year by year and shows what early closure would cost.

Extending PPF after 15 years

At maturity you can close the account, extend it with deposits in blocks of five years (by submitting Form 4 within a year), or leave it to be extended automatically without deposits. With deposits you may withdraw up to 60% of the block's opening balance over the block. Without deposits you can take one withdrawal of any size each year. The "Keep balance flat" button finds the yearly amount, balance × r ÷ (1 + r), that gives tax-free income without shrinking the corpus.

Tax: EEE and the effective return

PPF has EEE tax status. Interest and the maturity amount are tax-free under both regimes, but the ₹1.5 lakh deduction for deposits is available only under the old regime, and it is shared with EPF, ELSS and insurance premiums. The tax card converts PPF's rate into a tax-equivalent yield using r ÷ (1 − slab × 1.04), which is what a taxable FD would have to pay to match it. For old-regime taxpayers it also shows the effective return once the yearly tax saving is counted.

Rates and rules change
The PPF rate is reviewed every quarter, and the deposit cap, deduction and withdrawal rules can change through the Budget. The Income-tax Act, 2025 has also renumbered the relevant sections. Treat projections as estimates and confirm current rules with your bank or post office.

How does this PPF calculator work, and why deposit before the 5th?

It walks your account month by month, the way the scheme does: each month earns interest at rate ÷ 12 on the lowest balance between the 5th and the month end, and the year's interest is credited on 31 March. Money that arrives after the 5th is not in the account on the 5th, so it earns nothing for that month.

When exactly does my PPF account mature, and why can I make 16 deposits?

A PPF account matures after 15 complete financial years counted from the end of the year you opened it, which is 1 April of the opening FY's start year + 16. The opening year counts too, so a saver who deposits every year makes 16 deposits, and opening on 31 March instead of 1 April brings maturity forward by a full year.

Can I take a loan or withdraw from PPF before maturity?

From the 3rd to the 6th financial year you can borrow up to 25% of the balance at the end of the second year before the loan year. From the 7th year you can make one partial withdrawal per year of up to 50% of the lower of the balance four years earlier and the balance at the end of the previous year. The Loans & withdrawals tab shows both limits for every year of your plan.

What are my options at maturity?

You can close the account and take the money, extend it in blocks of 5 years with fresh deposits (by submitting Form 4 within a year of maturity), or simply leave it, in which case it is extended without deposits and keeps earning interest. With deposits you may withdraw up to 60% of the block's opening balance over the block; without deposits you can take one withdrawal of any size each year.

Is PPF tax-free under the new tax regime?

The interest and the maturity amount are tax-free under both regimes. The deduction for deposits, the ₹1.5 lakh limit formerly under section 80C, is available only under the old regime and is shared with EPF, ELSS, life insurance premiums and similar investments. The Income-tax Act, 2025 renumbers these sections, so confirm the current rules before you file.

What happens if I miss the ₹500 minimum in a year?

The account becomes discontinued: it keeps earning interest but you cannot take loans or withdrawals. You can revive it by paying the missed minimum deposits plus a small penalty for each missed year; check the current penalty with your bank or post office.
