What is a PPF Calculator?
A PPF Calculator is a free online tool that helps you calculate the maturity value of your Public Provident Fund (PPF) account based on your annual contribution, the prevailing interest rate, and your investment tenure. PPF is one of India's most trusted and tax-efficient long-term savings instruments, offering guaranteed returns backed by the Government of India.
PPF has a mandatory 15-year lock-in period and can be extended in blocks of 5 years (with or without fresh deposits) after maturity. It enjoys EEE (Exempt-Exempt-Exempt) tax status — the annual contribution qualifies for a deduction under Section 80C (up to INR 1.5 lakh per year under the old regime), the interest earned is completely tax-free, and the maturity amount is fully exempt from income tax.
For conservative, long-term investors seeking a government-guaranteed, inflation-beating savings instrument for goals like retirement or children's education, PPF is often the foundational component of a financial plan. This calculator shows year-wise growth so you can visualise the power of compounding over the 15–30 year horizon.
How is PPF Interest Calculated?
PPF interest is compounded annually and credited to the account on March 31st each year. The interest for each year is calculated on the minimum balance between the 5th and the last day of each calendar month:
Annual Interest = Opening Balance × Rate / 100 + (Deposit × Rate / 100)
Key Rule: To earn interest on your annual deposit for the full financial year, deposit before April 5th each year. If deposited after April 5th, the deposit earns interest only from the following month. Depositing a lump sum before April 5th maximises your annual interest earnings.
Why PPF is Considered the Best Risk-Free Investment in India
- Sovereign Guarantee: PPF is backed by the Government of India — making it the safest investment available, unlike bank FDs which are insured only up to INR 5 lakh.
- Triple Tax Exemption (EEE): 80C deduction on investment, tax-free interest accrual, and completely tax-free maturity — making the effective pre-tax return much higher than the stated rate for taxpayers in higher slabs.
- Inflation-Adjusted Returns: At 7.1% p.a. tax-free, PPF often beats FD returns (which are taxable) and matches or exceeds debt mutual fund returns on a post-tax basis for investors in the 30% tax slab.
- Attachment Protection: PPF balance cannot be attached by courts or creditors (except the Income Tax department for tax dues). This protection is not available for FDs, shares, or mutual funds.
- Flexible Contributions: Contribute any amount from INR 500 to INR 1,50,000 per year, in any number of installments (up to 12 per year) as per your cash flow.

Partial Withdrawal and Loan Against PPF
PPF allows partial withdrawals and loans, providing liquidity despite the long lock-in:
- Partial Withdrawal: Allowed from Year 7 onwards. Maximum withdrawal = 50% of the balance at the end of Year 4 (measured from the year preceding the year of withdrawal). Only one withdrawal is permitted per financial year.
- Loan Against PPF: Available from Year 3 to Year 6. Maximum loan = 25% of the balance at the end of the second year preceding the loan application. Must be repaid within 36 months. Interest = PPF rate + 1% p.a.
Disclaimer: PPF interest rate is declared quarterly by the Ministry of Finance and may change. The current rate of 7.1% has been unchanged since April 2020. This calculator uses the current rate for all years — actual returns will depend on future rate changes. 80C deductions apply only under the old tax regime.
