Quick answer
PPF maturity amount = P × [(1 + r)n − 1] ÷ r × (1 + r), where P is the yearly deposit, r is the annual rate and n is the number of years, assuming you deposit at the start of each year. At the current 7.1% rate, ₹1,50,000 a year for 15 years grows to about ₹40,68,209, of which ₹18,18,209 is tax-free interest.

PPF is one of the most popular long-term savings options in India because it combines a government guarantee with tax-free returns. The catch is that the money is locked in for 15 years, so it pays to know what you will get before you commit.
This PPF maturity calculator compounds your deposits year by year, the same way your bank or post office does. It works in your browser and does not store any data.
What Is the Public Provident Fund (PPF)?
The Public Provident Fund is a savings scheme backed by the Government of India. You can open an account at a post office or an authorised bank, deposit between ₹500 and ₹1,50,000 each financial year, and earn interest set by the government every quarter.
- Lock-in: 15 full financial years, with partial withdrawals allowed from the seventh year.
- Extension: after maturity you can extend in blocks of 5 years, with or without new deposits.
- Interest: worked out monthly on the lowest balance between the 5th and the last day of the month, and credited once a year on 31 March.
- Tax: deposits qualify for deduction under Section 80C in the old tax regime, and the interest and maturity amount are tax-free.
The PPF interest rate is 7.1% a year for the October–December 2026 quarter, the same rate it has held for several years. The government reviews it every quarter, so the calculator lets you change it.
PPF Maturity Formula
The calculator treats your yearly deposit as an annuity due, meaning money goes in at the start of each year:
- Maturity amount (F) = P × [(1 + r)n − 1] ÷ r × (1 + r)
- Total invested = P × n
- Interest earned = F − total invested
Depositing before the 5th of April each year gets you interest for the full year. If you deposit later in the year, your actual maturity amount will be a little lower than the figure shown.
How to Use the PPF Maturity Calculator
Step 1: Enter Your Yearly Deposit
Type how much you plan to deposit each financial year, up to the ₹1,50,000 limit. Keep the interest rate at 7.1% or change it to test other rates, and leave the period at 15 years for a standard account.
Step 2: See Your Maturity Amount
Press Calculate Maturity. With ₹1,00,000 a year for 15 years, the account grows to ₹27,12,139. You invest ₹15,00,000 and earn ₹12,12,139 in interest, all of it tax-free.
Step 3: Compare Extension Periods
Use the 20, 25 or 30 year buttons to see the effect of extending your account. Investing the full ₹1,50,000 a year for 25 years builds a corpus of ₹1,03,08,015, more than ₹1 crore, from ₹37,50,000 of deposits.

Every row comes from the PPF maturity calculator above. The table shows why time matters more than the deposit itself. The last ten years of a 25-year account add more than the first fifteen.
Tips to Get the Most From Your PPF Account
- Deposit before 5 April each year so the whole amount earns interest for all 12 months.
- If you pay monthly, deposit before the 5th of each month.
- Keep the account active with at least ₹500 a year to avoid a penalty.
- Extend the account after 15 years if you do not need the money; the compounding is strongest at the end.
- Use PPF for the safe part of your portfolio and other options for growth.
