The PPF Compounding & Interest Formulas
PPF interest is calculated monthly on the lowest closing balance between the 5th and the last day of each month, but credited to the account annually on March 31st.
Monthly Interest Base = Minimum Balance in Account between 5th and End of Month
Annual Interest Credited = Sum of (Monthly Interest Base * (Annual Rate / 12 / 100)) for 12 months
Future Maturity Value (Annual Lump Sum Deposit P) = P * [ ((1 + r)^n - 1) / r ] * (1 + r)
Practical PPF Calculation Examples
Example 1: Maximum Annual Contribution (₹1,50,000/year for 15 Years at 7.1% p.a.)

- Tenure: 15 Years (15 Annual Deposits)
- Total Principal Invested: ₹22,50,000
- Total Tax-Free Interest Earned: ₹18,18,209
- Total Tax-Free Maturity Corpus: ₹40,68,209
Example 2: Monthly ₹10,000 PPF SIP (for 15 Years at 7.1% p.a.)
An investor deposits ₹10,000 on the 4th of every month.
- Total Principal Invested: ₹18,00,000

- Annual Contribution: ₹1,50,000 (Full ₹1.5L 80C deduction claimed each year)

- Total Compound Interest Earned: ₹18,18,209
- Maturity Corpus (100% Tax-Free): ₹40,68,209 (Exempt-Exempt-Exempt status u/s 10(11)).
Common Ppf Calculator Mistakes to Avoid
- Exceeding the ₹1.5 Lakh Annual Contribution Limit Across All Accounts: Depositing more than ₹1.5 Lakhs per financial year across personal and minor child PPF accounts combined, forfeiting interest on excess deposits.
- Missing the 5th of the Month Deposit Cutoff for Monthly Interest Calculation: Depositing monthly PPF installments after the 5th of the month, losing an entire month's interest (interest is calculated on minimum balance between 5th and end of month).
- Failing to Deposit the Minimum ₹500 Annual Contribution: Depositing zero funds in a financial year, causing the PPF account to become discontinued/defunct and incurring ₹50/year penalty fees to reactivate.
- Attempting Full Withdrawal Before the 15-Year Lock-In Maturity: Expecting full liquidity before 15 years, ignoring strict partial withdrawal rules (allowed only from 7th financial year up to 50% of balance).
- Ignoring 5-Year Extension Options with or Without Further Contributions: Closing a 15-year PPF account at maturity without evaluating 5-year block extensions that continue compounding tax-free interest.
- Confusing EEE (Exempt-Exempt-Exempt) Status with Bank FD Tax Rules: Assuming PPF interest is taxable like bank FDs, forgetting PPF enjoys full EEE tax-free status on deposit, interest, and maturity.
Frequently Asked Questions
What is the lock-in period for a PPF account and can I withdraw early?
A PPF account has a mandatory lock-in period of 15 years. You cannot make full withdrawals before this period ends, but partial withdrawals are permitted from the 7th financial year onwards under certain conditions. After the 15-year term, you may extend the account in blocks of 5 years.
How is PPF interest calculated and when is it credited?
PPF interest is calculated on the lowest balance in your account between the 5th and last day of each calendar month, then credited at the end of the financial year (March 31). To maximise interest, it is advisable to deposit before the 5th of each month so the deposit counts in that month's calculation.
What is the minimum and maximum amount I can invest in PPF per year?
You must deposit a minimum of ₹500 per financial year to keep the account active. The maximum permissible deposit is ₹1,50,000 per financial year across all your PPF accounts. Deposits can be made in a lump sum or in up to 12 instalments.
What tax benefits does a PPF investment offer?
PPF follows the Exempt-Exempt-Exempt (EEE) structure: the amount you invest qualifies for deduction under Section 80C; the interest earned is fully tax-free; and the maturity proceeds are also exempt from income tax. This makes PPF one of the most tax-efficient savings instruments available in India.
How does this calculator estimate my PPF maturity amount?
The calculator uses the standard PPF compounding formula, applying the prevailing interest rate (announced by the government quarterly) to your annual deposits over the chosen tenure. It compounds interest annually and shows your total invested amount, interest earned, and projected maturity value.
Can I open multiple PPF accounts?
No, an individual is allowed to open only one PPF account in their name across all banks and post offices in India. However, you can open a second account in the name of your minor child as a guardian.
What is the maximum amount I can invest in PPF?
The maximum limit is ₹1,50,000 per financial year. Even if you hold an account for yourself and act as a guardian for a minor's account, the combined total contribution across both accounts cannot exceed ₹1.5 Lakhs in a single year to claim tax benefits.
What happens if I forget to deposit ₹500 in a year?
If you fail to make the minimum ₹500 deposit in a financial year, your PPF account becomes inactive. To revive it, you must pay a penalty of ₹50 for every year defaulted, along with the minimum deposit of ₹500 for each missed year.
When is the best time to deposit money into a PPF account?
To maximize your interest, you should deposit the money on or before the 5th of the month (if making monthly deposits), or between April 1st and April 5th (if making a yearly lump-sum deposit). This ensures the money earns interest for that entire month.
Can an NRI open a PPF account?
Non-Resident Indians (NRIs) are not permitted to open a new PPF account. However, if an Indian resident opens a PPF account and subsequently becomes an NRI during the 15-year tenure, they are allowed to continue contributing to the account until maturity on a non-repatriable basis.
Can I take a loan against my PPF balance?
Yes, you can take a loan against your PPF account from the 3rd to the 6th financial year of opening the account. The loan amount is capped at 25% of the balance available at the end of the second year immediately preceding the year you apply for the loan.
