What is PPF (Public Provident Fund)?

PPF is a government-backed long-term savings scheme with guaranteed, tax-free returns. It's one of the safest investment options in India with the current interest rate of 7.1% per annum, compounded annually.

PPF has a 15-year lock-in period, but you can extend it in blocks of 5 years after maturity. It's ideal for building a retirement corpus or long-term wealth with zero risk.

PPF Interest Calculation

PPF interest is calculated on the minimum balance between the 5th and the last day of each month. To maximize interest, deposit your money before the 5th of the month.

Formula: A = P × [(1+r)^n - 1] / r × (1+r)

For yearly deposits with annual compounding

Smart PPF Strategies

1. Deposit Before 5th of April

Make your yearly deposit before April 5th to earn interest for the full year. Depositing on April 6th means you lose one month of interest.

2. Open Account for Your Child

Open a PPF account in your minor child's name. The ₹1.5 lakh limit is per account, so you can invest up to ₹3 lakh (₹1.5L each) with 80C benefit on your contribution.

3. Extend After Maturity

After 15 years, extend in 5-year blocks with or without fresh contributions. Your corpus keeps earning 7.1% tax-free — better than most FD rates.

4. Use for Retirement Planning

Start early. ₹1.5 lakh/year for 25 years (15 + two 5-year extensions) can grow to over ₹1 crore — completely tax-free retirement corpus.

How to Open PPF Account

  1. Where: Any nationalized bank (SBI, PNB, etc.) or Post Office
  2. Documents: PAN, Aadhaar, Address proof, Passport photo
  3. Nomination: Mandatory — can be family member or any person
  4. Online: Available through bank net banking (SBI YONO, etc.)

Frequently Asked Questions

Can NRIs open PPF account?

NRIs cannot open new PPF accounts. However, if you had a PPF account before becoming NRI, you can continue it till maturity (but cannot extend). Interest rate for NRI accounts is same as resident accounts.

What if I miss a year's deposit?

Minimum ₹500/year is required to keep account active. If missed, account becomes inactive. Reactivate by paying ₹500 per year missed + ₹50 penalty per year. Interest is lost for inactive years.

Can I have multiple PPF accounts?

No, only one PPF account per person is allowed. Having multiple accounts (knowingly or unknowingly) can lead to closure of extra accounts without interest.

Is PPF guaranteed by government?

Yes, PPF is backed by the Government of India — it's a sovereign guarantee. Unlike bank FDs which are insured only up to ₹5 lakh, your entire PPF balance is 100% safe.
