What is PPF (Public Provident Fund)?
PPF, or Public Provident Fund, is a long-term savings scheme backed by the Government of India. It was introduced in 1968 by the National Savings Institute under the Ministry of Finance. Unlike EPF, which is limited to salaried employees, PPF is open to all Indian citizens, including self-employed professionals, freelancers, and homemakers.
PPF enjoys EEE (Exempt-Exempt-Exempt) tax status, meaning your contributions, the interest earned, and the maturity amount are all completely tax-free. This makes it one of the most tax-efficient savings instruments available in India today.
- Open to all Indian citizens, including salaried, self-employed, and minors (through a guardian)
- Current interest rate is 7.1% per annum for FY 2024-25, compounded annually
- Lock-in period of 15 years, extendable in blocks of 5 years after maturity
- Maximum annual deposit of ₹1,50,000 with Section 80C tax deduction benefit
- Backed by the Government of India, making it one of the safest investment options
How is PPF Interest Calculated?
PPF interest is compounded annually, and the maturity amount depends on your yearly investment, the interest rate, and the number of years you stay invested. The formula for calculating the PPF maturity value is:
Maturity = P x [((1+r)^n - 1) / r] x (1+r)
P = Yearly investment amount (deposited at the start of each year)
r = Annual interest rate (as a decimal, so 7.1% = 0.071)
n = Number of years of investment
Interest is calculated on the lowest balance between the 5th and the last day of each month. This means deposits made before the 5th of a month earn interest for that entire month. Deposits made after the 5th only start earning interest from the following month. The interest is credited to the account at the end of each financial year (March 31).
PPF Calculation with Example
Let's calculate the PPF maturity value for someone who invests the maximum amount of ₹1,50,000 per year for the standard 15-year period at the current 7.1% interest rate.
Yearly Investment: ₹1,50,000
Investment Period: 15 years
Interest Rate: 7.1% per annum, compounded annually
Total Investment: ₹1,50,000 x 15 = ₹22,50,000
Maturity Value: Approximately ₹40,68,209
Total Interest Earned: Approximately ₹18,18,209
In this example, you invest ₹22.5 lakhs over 15 years and receive approximately ₹40.68 lakhs at maturity. The interest earned (₹18.18 lakhs) is nearly 81% of your total investment, and all of it is completely tax-free. If you extend the account by 5 more years (to 20 years total), the maturity value grows to approximately ₹66.58 lakhs.
Why is PPF Important?
PPF is one of the most popular long-term savings instruments in India for good reason. Here is why millions of Indians trust PPF for their financial planning:
- EEE tax status: Contributions qualify for Section 80C deduction (up to ₹1.5 lakh). Interest earned and the maturity amount are both completely tax-free. To understand other tax-saving salary components, explore our detailed guide
- Government backing: PPF is a sovereign guarantee instrument. Your principal and interest are guaranteed by the Government of India, making it virtually risk-free
- Competitive returns: At 7.1%, PPF offers higher returns than most bank fixed deposits, and the returns are entirely tax-free, making the effective post-tax return even more attractive
- Retirement planning: The 15-year lock-in encourages disciplined long-term saving. Combined with instruments like gratuity calculator projections, PPF forms a solid retirement corpus
- Loan and withdrawal facility: Despite the lock-in, you can take a loan against your PPF balance from the 3rd to 6th year, and partial withdrawals are allowed from the 7th year onwards

PPF Interest Rate History
The PPF interest rate is set by the Ministry of Finance and reviewed every quarter. Here is how the rate has changed over the last decade:
FY 2024-25: 7.1%
FY 2023-24: 7.1%
FY 2022-23: 7.1%
FY 2021-22: 7.1%
FY 2020-21: 7.1% (reduced from 7.9% in Q1)
FY 2019-20: 7.9% (Q1-Q3), 7.1% (Q4)
FY 2018-19: 8.0%
FY 2017-18: 7.6% (Q1), 7.8% (Q2-Q4)
FY 2016-17: 8.1% (Q1-Q3), 8.0% (Q4)
FY 2015-16: 8.7%
The PPF rate has declined from 8.7% in 2015-16 to 7.1% in 2020-21, where it has stayed for over four years. Despite this reduction, PPF remains attractive because the returns are entirely tax-free. For someone in the 30% tax bracket, the effective pre-tax equivalent return of 7.1% PPF is approximately 10.14%.

PPF vs EPF vs NPS
India offers several retirement-focused savings instruments. Here is how PPF compares with EPF and NPS to help you choose the right mix for your financial goals:
PPF (Public Provident Fund): Open to all citizens. Voluntary. Maximum ₹1,50,000/year. Interest rate 7.1% (FY 2024-25). 15-year lock-in. EEE tax status (fully tax-free). Government guaranteed. No employer contribution
EPF (Employee Provident Fund): Mandatory for salaried employees in organizations with 20+ employees. 12% employee + 12% employer contribution of basic + DA. Interest rate 8.25% (FY 2024-25). Withdrawal at age 58 or after 2 months of unemployment. Use our PF calculator to estimate your EPF corpus
NPS (National Pension System): Open to all citizens aged 18-70. Market-linked returns (typically 8-10% historically). Lock-in until age 60. 60% of corpus is tax-free at maturity, 40% must be used to buy an annuity. Additional ₹50,000 deduction under Section 80CCD(1B) beyond the ₹1.5 lakh 80C limit
For risk-averse investors who want guaranteed, tax-free returns, PPF is ideal. Salaried employees benefit most from EPF due to employer matching. NPS suits those comfortable with market-linked returns who want higher growth potential. A combination of all three creates a well-diversified retirement portfolio. Employers can simplify PF and payroll compliance through Attendo (formerly Petpooja Payroll), which automates deductions and statutory filings.
