Worked Example Walkthrough
Scenario: ₹1,50,000 statutory maximum annual deposit deposited before April 5th for 15 financial years at 7.10% p.a.
Calculation: Annual compounding on March 31 with Section 80C deduction and exempt interest and maturity (EEE).
Result: Invested: ₹22,50,000 | Tax-Free Interest: ₹18,18,209 | Total Tax-Free Maturity: ₹40,68,209
Assumptions & Methodology
- Deposit made before the 5th of April earns interest for all 12 months of the financial year.
- Statutory lock-in is 15 complete financial years.
About this Calculation Model
The Public Provident Fund (PPF) Calculator projects the 15-year statutory maturity corpus, annual interest accumulations, and 5-year block extension growth of India's premier government-backed savings scheme. It models the exact monthly minimum balance interest rule (between the 5th and end of each calendar month) under sovereign sovereign-backed EEE (Exempt-Exempt-Exempt) tax rules.

Statutory limits in India: Minimum ₹500 to maximum ₹1,50,000 per financial year.
2Statutory Interest Rate (%)

Interpreting Your Projections
PPF enjoys triple tax exemption (EEE): deposits are deductible under Section 80C, annual accrued interest is completely tax-free, and final maturity withdrawal is 100% exempt from income tax.
Important Statutory & Practical Considerations
- Statutory Deposit Cap: Total contributions are legally capped at ₹1,50,000 per financial year across all PPF accounts held by an individual (including accounts opened on behalf of minor children).
- Mandatory Lock-In: Complete withdrawal is permitted only after 15 complete financial years, though partial withdrawals and loans against PPF are permitted starting from Year 6 and Year 3 respectively.
- Quarterly Interest Rate Revisions: The Government of India reviews small savings rates quarterly; rates may adjust depending on government bond yields.
Frequently Asked Questions
Why is depositing before the 5th of the month important in PPF?
Under statutory PPF rules, interest is calculated on the lowest balance recorded in your account between the close of the 5th day and the end of the calendar month. If you deposit after the 5th, that deposit earns zero interest for that calendar month.
What is the EEE status of PPF?
EEE stands for Exempt-Exempt-Exempt: (1) Deposit is eligible for tax deduction under Section 80C; (2) Annual interest credited is completely exempt from income tax; (3) Final maturity amount withdrawn is 100% tax-free.
Can I extend my PPF account after 15 years?
Yes. Upon completing the 15-year statutory period, you can extend the account in blocks of 5 years indefinitely, either with continuing contributions or without further contributions while continuing to earn tax-free interest.
Can I take a loan against my PPF account or make partial withdrawals?
Yes. You can avail a loan against your PPF balance between the 3rd and 6th financial year at 1% interest above the prevailing PPF rate. Partial tax-free withdrawals are permitted starting from the 7th financial year, capped at 50% of the balance at the end of the 4th preceding year.
