How the PPF Calculator Works
A Public Provident Fund (PPF) account is a government-backed savings instrument with a 15-year lock-in. It offers guaranteed returns at a government-set interest rate, compounded annually.
The PPF Formula
For annual deposits made at the start of each year (annuity due):
PPF Maturity Value
FV = P x (1 + r) x [(1 + r)^n - 1] / r
Where:
- P = Annual deposit amount
- r = Annual interest rate (as decimal, e.g., 0.071)
- n = Number of years
- FV = Maturity value of your PPF account
Why PPF is Triple Tax-Free (EEE)
PPF enjoys the coveted EEE (Exempt-Exempt-Exempt) status under Indian tax law:
- Exempt #1: Your annual deposit (up to Rs 1.5L) qualifies for Section 80C deduction
- Exempt #2: The interest earned every year is completely tax-free
- Exempt #3: The maturity amount (principal + all interest) is fully tax-free
Key PPF Rules
- Lock-in: 15 years (extendable in 5-year blocks with or without deposits)
- Deposits: Rs 500 minimum to Rs 1,50,000 maximum per financial year
- Partial withdrawal: Allowed from 7th year onwards (up to 50% of balance at end of 4th preceding year)
- Loan against PPF: Available between 3rd and 6th year
- Premature closure: Only after 5 years, with 1% interest penalty, and only for specific reasons (serious illness, higher education)
Frequently Asked Questions
The current PPF interest rate is 7.1% per annum (as of Q4 FY 2025-26). The government reviews and sets the rate every quarter. It has remained at 7.1% since April 2020.
PPF interest is compounded annually. Interest for each month is calculated on the lowest balance between the 5th and the last day of the month. The accumulated interest is credited to the account at the end of the financial year (March 31).
Yes. After the initial 15-year maturity, you can extend your PPF in blocks of 5 years - either with or without fresh deposits. If extended with deposits, the account continues to earn interest and allows partial withdrawals.
The excess amount above Rs 1.5 lakh will not earn any interest and will not qualify for Section 80C tax deduction. It will simply be returned to you.
No. An individual can hold only one PPF account. If two accounts are opened by mistake, the second one is treated as irregular and will earn no interest. The Rs 1.5L annual limit applies to the single account.
For most taxpayers, yes. PPF interest is completely tax-free, while FD interest is taxable at your slab rate. A 7.1% PPF gives you the full 7.1%, whereas a 7% FD effectively gives only about 4.9% after 30% tax. The trade-off is PPF's 15-year lock-in vs FD's 5-year lock-in for tax-saving FDs.
Yes, PPF enjoys EEE (Exempt-Exempt-Exempt) tax status. The annual deposit qualifies for Section 80C deduction (up to Rs 1.5 lakh), the interest earned is tax-free, and the maturity amount is fully tax-free.
