PPF Calculator — Plan Your Public Provident Fund Corpus Year by Year

The Public Provident Fund is one of the most valuable financial instruments available to Indian residents — and one of the most underutilised in terms of strategic planning. PPF offers a rare combination: government-backed safety, competitive interest rates, and complete tax exemption at all three stages — contribution, accumulation, and maturity (the EEE structure). This PPF Calculator helps you model exactly how your corpus builds year by year, see the compounding effect across a 15–25 year horizon, and optionally discount the maturity amount for inflation to understand its real purchasing power.

Enter your yearly investment amount (₹500–₹1,50,000), your planned tenure, and the interest rate — currently 7.1% p.a. compounded annually. The calculator outputs a complete year-wise schedule showing opening balance, annual deposit, interest earned, and closing balance, plus a maturity summary. Toggle the inflation adjustment to see what your corpus will be worth in today's money.

What Makes PPF Uniquely Valuable

PPF's EEE (Exempt-Exempt-Exempt) tax status is its most powerful advantage. Your annual contributions qualify for deduction under Section 80C (up to ₹1.5 lakh per year, shared across all 80C instruments). The interest earned each year is not added to your taxable income. And the entire maturity amount — principal plus all accumulated interest — is received completely tax-free. No other commonly available savings instrument combines all three exemptions.

Compare this to a bank FD at the same 7.1% rate: for an investor in the 30% tax bracket, the post-tax FD return is approximately 4.97% p.a. The PPF, at 7.1% tax-free, is equivalent to earning about 10.1% on a fully taxable instrument. This makes PPF especially powerful for high-income earners who are in the 20–30% tax bracket.

PPF is backed by the Government of India with sovereign guarantee — there is no credit risk, no market risk, and no possibility of default. The account can be opened at any major scheduled bank or post office branch, and online management is available through most banks' net banking portals.

The PPF Interest Calculation — How It Works

PPF interest is calculated on the minimum balance between the 5th and the last day of each calendar month, then summed and credited to the account at the end of the financial year (31 March). This monthly minimum balance rule has an important practical implication: if you deposit before the 5th of April each year, your annual contribution earns interest for the full financial year. If you deposit after the 5th, it earns interest only from the next month — losing one month of interest on that year's contribution.

The PPF maturity formula is:

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

Where:

  • F = Maturity value
  • P = Annual deposit amount
  • r = Annual interest rate in decimal (7.1% = 0.071)
  • n = Number of years

Example: ₹1,50,000 deposited annually for 15 years at 7.1%. Total invested = ₹22,50,000. Maturity amount ≈ ₹40,68,209. Tax-free interest earned ≈ ₹18,18,209 — an 81% gain on the invested amount, entirely free of tax.

Extend the same for 20 years: total invested = ₹30,00,000, maturity ≈ ₹66,58,288. Extend to 25 years: maturity ≈ ₹1,02,35,000 — crossing ₹1 crore on the maximum annual deposit. The compounding effect after year 15 is dramatically more powerful than the first 15 years, which is why financial planners frequently recommend extending PPF accounts after maturity.

PPF Liquidity — Withdrawals, Loans, and Extensions

Partial withdrawals: From the 7th financial year onwards, you may withdraw up to 50% of the balance at the end of the 4th year preceding the withdrawal year, or the balance at the end of the preceding year — whichever is lower. One withdrawal per financial year is permitted.

Loans against PPF: From the 3rd through the 6th financial year, you can take a loan of up to 25% of the balance at the end of the second year preceding the loan application. The loan must be repaid within 36 months. The interest on the PPF loan is 1% above the prevailing PPF rate — far lower than any personal loan.

Extension after maturity: At the end of 15 years, you have three options: close and withdraw the full amount tax-free; extend without contribution (the balance continues earning PPF interest, and you can make one withdrawal per year); or extend with contribution in 5-year blocks (you continue depositing up to ₹1.5 lakh annually and the 80C benefit continues). The extension-with-contribution option is often the most financially optimal for investors who don't need the corpus immediately.

PPF vs ELSS vs NPS — Choosing the Right 80C Vehicle

PPF vs ELSS: ELSS (Equity Linked Savings Scheme) has only a 3-year lock-in (shortest among 80C instruments) and historically delivers 12–15% CAGR over long periods, but returns are market-linked and not guaranteed. ELSS gains above ₹1 lakh per year attract 10% LTCG tax. PPF offers guaranteed, fully tax-free returns — no LTCG, no uncertainty. For the risk-averse, PPF is superior; for long horizons and risk tolerance, ELSS may build more wealth in absolute terms.

PPF vs NPS: NPS offers potentially higher returns (market-linked equity allocation), an additional ₹50,000 deduction under Section 80CCD(1B) beyond the 80C limit, but only 60% of the corpus is tax-free at retirement — 40% must be used to buy an annuity which is taxable as income. PPF's entire maturity amount is tax-free with no annuity requirement, making it cleaner for pure corpus building. Many investors use both: PPF for the guaranteed, tax-free core and NPS for the equity-linked supplement.

Frequently Asked Questions About PPF

If you fail to make the minimum deposit of ₹500 in any financial year, your PPF account becomes dormant (discontinued). To reactivate it, you must pay ₹50 penalty per missed year along with the minimum deposit of ₹500 for each missed year. The account continues to earn interest even during the dormant period, but you cannot make withdrawals or take loans until it is reactivated.
NRIs cannot open a new PPF account. However, if a resident Indian becomes an NRI after opening a PPF account, they may continue the account until maturity but cannot extend it beyond the original 15 years. Contributions from NRI status are not eligible for 80C deduction under the residency rules that apply to NRIs.
Deposit before 5 April each year (the first week of the financial year). PPF interest is calculated on the minimum balance between the 5th and last day of each month. A deposit made before 5 April earns interest for all 12 months of the financial year on that contribution. A deposit made after 5 April loses one month of interest. Over 15–25 years, this timing difference compounds to a meaningful sum.
Yes. Parents or legal guardians can open a PPF account on behalf of a minor child. However, the combined contribution across the guardian's own PPF account and the minor's account cannot exceed ₹1.5 lakh per financial year. The 80C deduction for contributions to a minor's PPF account is claimed by the parent/guardian.
For investors who don't need the corpus immediately, extending with contributions is usually very worthwhile. The compounding effect in years 16–25 is far more powerful than in years 1–15 because the base balance is now large. A corpus of ₹40 lakh at year 15 grows to approximately ₹66 lakh by year 20 and ₹1.02 crore by year 25 (at ₹1.5 lakh/year, 7.1% rate) — entirely tax-free. The 15-year extension decision should be made at least 1 year before maturity.
Yes. The government reviews and announces the PPF interest rate quarterly alongside other small savings scheme rates. The rate has ranged from 7.1% to 8.7% in recent years. This calculator uses a fixed rate for projection — actual returns will vary based on future rate revisions. For conservative planning, model at 7% (below the current rate); for optimistic scenarios, try 7.5–8%.
PPF balance cannot be attached by any court order or decree with respect to any debt or liability incurred by the subscriber. This protection is provided under the Public Provident Fund Act. This makes PPF particularly valuable for self-employed individuals and business owners as a protected retirement corpus that creditors cannot access even in the event of insolvency.
