The Public Provident Fund is a long term savings account backed by the Government of India and opened at a post office or a bank. India Post lists a deposit of ₹500 to ₹1,50,000 in each financial year, a term of 15 financial years and interest compounded once a year. The rate is set by the government every quarter; the calculator starts at 7.1%, the rate India Post showed when it was checked on 2 November 2026. Enter the yearly deposit and the rate to see the maturity value, the total deposited, the total interest and the balance at the end of each of the 15 years. The working assumes each year's deposit sits in the account for the whole year, which gives the most interest the deposit can earn. The arithmetic happens in this browser and the figures are not saved.

Worked example
The full ₹1,50,000 deposited at the start of each financial year for 15 years, at 7.1% for every year. All figures are INR.
| Input | Value |
|---|---|
| Deposit each financial year | INR 1,50,000.00 |
| Interest rate | 7.1% a year, compounded yearly |
| Term | 15 financial years |
Year 1: 1,50,000 x 7.1% = 10,650 of interest, balance 1,60,650 Year 2: (1,60,650 + 1,50,000) x 7.1% = 22,056.15, balance 3,32,706.15 Each later year adds 1,50,000 and a year of interest on the new balance Year 15 balance = 40,68,209.23 Deposits = 1,50,000 x 15 = 22,50,000, so the interest is 18,18,209.23
- Maturity value after 15 years
- INR 40,68,209.23
- Total deposited
- INR 22,50,000.00
- Total interest
- INR 18,18,209.23
The closed form of a deposit at the start of each year, 1,50,000 x ((1.071^15 - 1) / 0.071) x 1.071, gives 40,68,209.22; the table rounds each year's interest to the paisa, which adds one paisa.
How the PPF maturity value is worked out
Interest in year y = (balance at the end of year y - 1 + deposit) x rate
Balance at the end of year y = balance at the end of year y - 1 + deposit + interest in year y
Maturity value = balance at the end of year 15; total interest = maturity value - 15 x deposit
A PPF account runs for 15 financial years from April to March. India Post describes the interest as compounded yearly, so the calculator adds interest once a year and the next year's interest is earned on it too. Each year the deposit is added first, the year's interest is worked out on the new balance and rounded to the paisa, and the interest is added at the end of the year.
The deposit is the same in every year and must be between ₹500 and ₹1,50,000, the limits India Post states for a financial year. An amount outside them is refused with a message rather than trimmed, so the figures always describe a deposit the scheme accepts.
One assumption shapes the result. The scheme's own rule for which balance earns interest in each month could not be read on an official page when the tool was checked, so the calculator takes each deposit to be in the account for the whole year. That is the most interest a deposit can earn, the case of paying the full amount on the first day of the financial year. A deposit made later in the year, or in monthly parts, can earn less, and the gap matters most in the early years, when the deposits are a large share of the balance.
The rate is an input. The government reviews it every quarter, and the calculator holds whatever is typed for all 15 years. It starts at 7.1%, the rate on the India Post savings schemes page when it was checked on 2 November 2026. The quarter that rate belongs to was not confirmed on an official notice, so the page names the date it was read instead.
Not modeled: extending the account in blocks of five years after maturity, loans and withdrawals against the balance, and the tax treatment of deposits and interest.
Frequently asked questions
How is PPF interest calculated here?
Each year the deposit is added to the balance and the whole amount earns a year of interest at the rate entered, added at the end of the year. A deposit of 1,50,000 at 7.1% earns 10,650 in year 1, so the balance is 1,60,650. In year 2 a second 1,50,000 brings it to 3,10,650, which earns 22,056.15.
What is the PPF maturity value on 1,50,000 a year?
At 7.1% for all 15 years, deposits of 1,50,000 a year add up to 22,50,000, and the account grows to about 40,68,209 with 18,18,209 of interest. The figure assumes each deposit is in the account for the whole year and the rate never changes. A rate change in any quarter moves the real result.
What are the PPF deposit limits?
India Post states a minimum of 500 and a maximum of 1,50,000 in a financial year, paid as a lump sum or in up to 12 deposits. The calculator refuses an amount outside that range. An account with no deposit of at least 500 in a year is treated as discontinued until it is revived with a fee of 50 for each year missed plus the 500.
Why does the rate show a check date?
The government reviews small savings rates every quarter, so the PPF rate can change four times a year. The calculator starts at 7.1%, the rate shown on India Post when it was checked on 2 November 2026, and the date is there so the figure is never read as a promise. Type a different rate to see its effect on the maturity value.
Does the deposit date in the year matter?
It can. The official rule for which balance earns interest in a month could not be read when the tool was checked, so the calculator makes one plain assumption: each deposit is in the account for the full financial year. That is the most a deposit can earn. Money paid in later in the year, or in monthly parts, can earn less than shown.
