Module C: Formula & Methodology Behind PPF Calculations

Maturity Amount = P × [(1 + r)ⁿ – 1] / r
Where:
P = Annual investment amount
r = Annual interest rate (7.9% or 0.079)
n = Investment period in years
Key characteristics of PPF calculations:
- Interest is compounded annually and credited on 31st March each year
- Contributions must be made before 5th of each month to earn interest for that month
- The minimum tenure is 15 years, with extension options in 5-year blocks
- Partial withdrawals are allowed from the 7th financial year
- Loan facility available from 3rd to 6th financial year

Module G: Interactive PPF FAQ
What happens if I don’t invest the minimum ₹500 in a year?
Your PPF account will become inactive. To reactivate it, you’ll need to pay a penalty of ₹50 for each year of default along with the minimum ₹500 contribution for each missed year. The account will then be restored to active status.
For example, if you miss contributions for 3 years, you’ll need to pay ₹500 × 3 = ₹1,500 plus ₹50 × 3 = ₹150 penalty to reactivate the account.
Can I have multiple PPF accounts?
No, an individual can only maintain one PPF account in their name. The rule changed in 2019, and now:
- Only one PPF account is allowed per person
- You can open accounts for minors, but the total deposit across all accounts cannot exceed ₹1,50,000 annually
- Having multiple accounts can lead to closure of additional accounts without interest
Exception: If you had multiple accounts opened before the rule change (before 12/12/2019), you can continue them but cannot open new ones.
How is PPF interest calculated monthly?
While PPF interest is compounded annually, the monthly calculation follows these rules:
- Interest is calculated on the minimum balance between the 5th and last day of each month
- Contributions made before the 5th of a month earn interest for that month
- The annual interest is credited to your account on 31st March each year
- Interest rate is set by the government quarterly (though it often remains stable for years)
Example: If you deposit ₹10,000 on 4th April and another ₹10,000 on 6th April, only the first ₹10,000 will earn interest for April.
What are the tax benefits of PPF under the new tax regime?
PPF maintains its EEE (Exempt-Exempt-Exempt) tax status even under the new tax regime:
- Contributions: Eligible for deduction under Section 80C (up to ₹1,50,000) in both old and new tax regimes
- Interest: Completely tax-free in both regimes
- Maturity: Entire corpus is tax-free at withdrawal
However, note that in the new tax regime (introduced in Budget 2023), you lose most other deductions except a few like PPF and NPS. So PPF becomes even more valuable for tax planning.
Can NRIs continue their existing PPF accounts?
Yes, NRIs can continue their existing PPF accounts until maturity but cannot open new accounts. Key points:
- Existing accounts can be maintained until the original 15-year term completes
- NRIs cannot extend the account beyond 15 years
- Contributions must be made from NRE/NRO accounts (not foreign accounts)
- Interest remains tax-free in India, but may be taxable in the country of residence
After maturity, NRIs must close the account and withdraw the funds. The entire corpus remains tax-free in India.
