How the PPF calculator works

The Public Provident Fund (PPF) is a government-backed, long-term small savings scheme established under the Public Provident Fund Scheme, 2019. Interest is compounded annually and calculated on the minimum balance in the account between the close of the 5th day and the end of each calendar month.

Assuming annual deposits are made on or before the 5th of April each financial year, the maturity amount follows the standard annuity-due compound accumulation equation:

F = P × [((1 + i)n − 1) ÷ i] × (1 + i)

  • F — Total maturity value at the end of the lock-in tenure
  • P — Annual deposit amount (statutory maximum ₹1,50,000 per financial year)
  • i — Annual statutory interest rate as a decimal (e.g. 0.071 for 7.1% p.a.)
  • n — Account tenure in complete financial years (mandatory 15 years; extendable in 5-year blocks)

Worked example: ₹1,50,000 annual deposit for 15 years at 7.1% p.a.

Consider an individual maximizing their statutory limit with an annual deposit of ₹1,50,000 deposited before April 5th every year for the full 15-year tenure:

1. Annual Contribution: ₹1,50,000 deposited annually on or before April 5th

2. Tenure: 15 complete financial years (180 months)

3. Cumulative Capital Invested: 15 × ₹1,50,000 = ₹22,50,000

4. Milestone Growth:

  • Year 5: Invested ₹7,50,000 → Balance: ₹9,74,383 (Interest earned: ₹2,24,383)
  • Year 10: Invested ₹15,00,000 → Balance: ₹23,54,482 (Interest earned: ₹8,54,482)
  • Year 15 (Maturity): Invested ₹22,50,000 → Balance: ₹40,68,209

5. Total Accumulated Interest: ₹40,68,209 − ₹22,50,000 = ₹18,18,209

Interpreting your PPF results

Exempt-Exempt-Exempt (EEE) Advantage: PPF is one of India's few financial instruments enjoying complete EEE tax status. Contributions qualify for deduction under Section 80C (under Old Tax Regime), interest accrued annually is 100% tax-free, and the entire maturity proceeds of ₹40,68,209 are exempt from income tax. For a taxpayer in the 30% slab (+ 4% cess), matching this 7.1% tax-free return requires an equivalent pre-tax taxable yield of 10.32%.

Extension in 5-Year Blocks: After the initial 15-year maturity, the account can be extended indefinitely in blocks of 5 years with or without fresh contributions. Extending for 5 years (to Year 20) with continued contributions of ₹1.5L/year elevates the corpus to over ₹66 lakh due to compounding on an already substantial capital base.

Key assumptions and limitations

  • Quarterly Rate Revisions: Sourced from Ministry of Finance notifications. The calculator models a constant 7.1% p.a. rate across the entire duration; actual historical and future returns may vary as rates are reviewed quarterly by the Government of India.
  • Deposit Timing Rule: Assumes contributions arrive between the 1st and 5th of April each financial year. Contributions deposited after the 5th miss interest accrual for that calendar month.
  • Statutory Limits: Conforms strictly to government limits: minimum ₹500 and maximum ₹1,50,000 per financial year per individual account.
  • Simplified Accumulation: Does not simulate partial premature withdrawals (available from the 7th financial year) or loan-against-PPF facilities (available from the 3rd to 6th financial year).
  • Tax Regime Specific: Section 80C deductions are available under the Old Tax Regime only; the New Tax Regime does not offer 80C deductions (though PPF interest remains tax-free).

Frequently asked questions

When should I deposit money in PPF to get maximum interest?
Depositing between the 1st and 5th of April ensures your entire annual contribution earns interest for all 12 months of that financial year, because PPF interest is calculated on the minimum balance between the 5th and the end of each calendar month.
Can I extend a PPF account beyond 15 years?
Yes, a PPF account can be extended indefinitely in blocks of 5 years each, with or without continuing new contributions.
What is the tax status of Public Provident Fund (PPF)?
PPF enjoys Exempt-Exempt-Exempt (EEE) tax status in India. Contributions are deductible under Section 80C (up to ₹1.5 lakh), annual interest accrued is completely tax-free, and maturity proceeds are exempt from income tax.
What are the minimum and maximum yearly deposits in PPF?
The statutory minimum annual deposit required to keep a PPF account active is ₹500, and the maximum allowed deposit is ₹1,50,000 per financial year.
Can a loan or partial withdrawal be taken from PPF?
Yes. A loan facility is available from the 3rd to 6th financial year, and partial withdrawals are allowed from the 7th financial year onwards subject to statutory limits.
