PPF Calculator: How to Build a Tax-Free ₹41 Lakh Corpus with Just ₹12,500 Monthly

The Public Provident Fund (PPF) is one of India’s most dependable long-term savings options, especially for salaried people planning for their future. Despite stable interest rates for years, PPF remains popular because it is government-backed, risk-free, and offers completely tax-free returns.
How ₹12,500 Monthly Can Become ₹41 Lakh
At the current 7.1% interest rate, investing ₹12,500 every month (₹1.5 lakh per year) can grow your PPF balance to about ₹40.68 lakh in 15 years. Of this, more than ₹18 lakh will be earned purely through interest, and all of it is tax-free.
Why PPF Works?
PPF earns interest through annual compounding, which steadily grows your money over time. The rate has been fixed at 7.1% since April 2020. Its safety, stable returns, and EEE (Exempt-Exempt-Exempt) tax benefits make it a strong choice for secure savings.
Easy to Open and Flexible Deposits
Opening a PPF account is simple and can be done at any bank or post office. Any Indian citizen can have an account in their own name or for their minor child. You only need basic KYC documents like Aadhaar, PAN, address proof, and a nominee form. You can deposit anywhere between ₹500 and ₹1.5 lakh in a year, either in one go or in multiple instalments.
How Much You Can Earn?
If you invest the full ₹1.5 lakh every year at 7.1%, here is the 15-year breakup:
- Total investment: ₹22,50,000
- Maturity amount: ₹40,68,209
- Total interest earned: ₹18,18,209
This amount is completely tax-free.
PPF Offers Full Tax Benefits (EEE Category)
PPF is among the few schemes that offer full tax exemption.
- Your deposits up to ₹1.5 lakh qualify for tax deduction.
- Interest earned is not taxed.
- The maturity amount is also tax-free.
This makes PPF one of the safest and most tax-efficient investment options.
How to Open a PPF Account
You can open a PPF account online or offline using:
- Aadhaar, Voter ID, or Driving License

- Address proof
