What is PPF?

The Public Provident Fund (PPF) is a long-term savings scheme backed by the Government of India. You can open an account at a post office or a bank, deposit money every year, and earn interest that is set by the government.

Because the government guarantees it and the returns are tax-free, PPF is a popular choice for safe, long-term goals such as retirement or a child's education.

PPF rules at a glance

Lock-in15 financial years from the year you open the account
ExtensionIn blocks of 5 years, with or without further deposits
Interest rateSet by the government every quarter

How is PPF interest calculated?

Interest is worked out every month on the lowest balance in your account between the 5th and the last day of that month. It is added to your account once, at the end of the financial year, so it compounds yearly.

Maturity value for a yearly deposit made at the start of each year

F = P × [((1 + r)ⁿ − 1) ÷ r] × (1 + r)

For example, depositing ₹1.5 lakh at the start of every year for 15 years at 7.1% grows to about ₹40.68 lakh. You deposit ₹22.5 lakh and earn about ₹18.18 lakh in tax-free interest.

The government reviews the PPF rate every quarter. It has stayed at 7.1% for several years, but check the current rate before you plan and enter it in the calculator.

When to deposit for the most interest

Because interest uses the lowest balance after the 5th of each month, a deposit made on the 6th earns nothing for that month. Depositing on or before the 5th, and ideally the full year's amount before 5 April, earns the most.

Monthly deposits are fine too; the calculator shows how much a lump deposit at the start of the year would add over the same period.

PPF tax benefits

  • Deposits of up to ₹1.5 lakh a year can be claimed as a deduction under the old tax regime.
  • The interest earned every year is tax-free.
  • The maturity amount is tax-free.

This 'exempt at every stage' treatment makes PPF one of the most tax-efficient safe investments. The deduction on deposits is not available under the new tax regime, but the interest and maturity remain tax-free. Tax rules can change, so check the current position.

Loans, withdrawals and early closure

  • Loan: from the third to the sixth financial year, you can borrow against your PPF balance.
  • Partial withdrawal: from the seventh financial year, you can withdraw part of the balance once a year.
  • Early closure: after five full financial years, the account can be closed early for specific reasons such as serious illness or higher education, usually with a small interest penalty.

Limits and conditions apply to each option, so check with your bank or post office before you apply.

Extending your PPF after 15 years

At maturity you can close the account, or extend it in blocks of five years. You can extend with fresh deposits, which keep earning tax-free interest, or without deposits, in which case the existing balance keeps earning interest. Use the time period setting in the calculator to see the effect of extending.

Frequently asked questions

1.How much will I get if I invest ₹1.5 lakh a year in PPF for 15 years?

At 7.1% a year, depositing ₹1.5 lakh at the start of every year for 15 years grows to about ₹40.68 lakh, of which about ₹18.18 lakh is tax-free interest. The exact figure depends on the rate in each year.

2.What is the current PPF interest rate?

The government announces the PPF rate every quarter. It has been 7.1% for several years; check the latest rate with your bank or post office and enter it in the calculator.

3.Is it better to deposit monthly or yearly in PPF?

A single deposit before 5 April earns interest for the whole year, so it earns the most. Monthly deposits made on or before the 5th of each month are a good alternative if you prefer to spread your savings.

4.Can I withdraw money from PPF before 15 years?

You can take a loan from the third to the sixth year and make partial withdrawals from the seventh year. Full early closure is allowed only after five years and for specific reasons such as illness or higher education.

5.Is PPF interest taxable?

No. PPF interest and the maturity amount are both tax-free. Under the old tax regime, your deposits also qualify for a deduction of up to ₹1.5 lakh a year.

6.What happens if I miss a year's deposit?

The account becomes inactive. You can revive it by paying the minimum ₹500 for each missed year along with a small penalty.
