PPF Calculator India (2025-26)

What is PPF (Public Provident Fund)?

The Public Provident Fund (PPF) is a government-backed long-term savings scheme introduced in 1968 by the National Savings Institute of the Ministry of Finance. It is one of the most popular and trusted investment instruments in India, particularly among risk-averse investors who prioritize capital safety and guaranteed returns.

PPF offers a unique combination of safety (sovereign guarantee by the Government of India), attractive returns (currently 7.1% p.a., compounded annually), and complete tax exemption under the EEE (Exempt-Exempt-Exempt) framework. This triple exemption means your contribution qualifies for Section 80C deduction (up to ₹1.5 lakh), the interest earned is tax-free, and the maturity amount is entirely exempt from income tax.

PPF Interest Rate History

PPF interest rates are set by the Government of India every quarter. Over the past decade, PPF rates have gradually declined from 8.7% (2013-14) to the current 7.1%. Despite the reduction, PPF remains highly competitive when compared on a post-tax basis, especially for investors in the 30% tax bracket where the effective post-tax yield exceeds 10%.

How PPF Interest is Calculated

PPF interest calculation follows a specific methodology that is crucial to understand for maximizing returns:

1. Monthly Minimum Balance Method: Interest is calculated on the lowest balance between the 5th and the last day of each month. This means if you deposit ₹1,50,000 on April 3rd, you earn interest on that amount for the entire month. But if you deposit on April 6th, you earn zero interest for April.
2. Annual Compounding: While calculated monthly, PPF interest is compounded and credited annually on March 31st. This means the interest earned in Year 1 gets added to your principal, and you earn interest on the total amount in Year 2.
3. Pro Tip: To maximize returns, make your entire PPF deposit as a lump sum before April 5th each year. This ensures all 12 months of interest on the full amount, maximizing the compounding effect over 15+ years.

PPF Maturity Example — ₹1.5L/Year for 15 Years

If you invest the maximum allowed amount of ₹1,50,000 per year at the current rate of 7.1% p.a. for the standard 15-year tenure:

• Total Amount Invested: ₹22,50,000 (₹1.5L × 15 years)
• Total Interest Earned: ₹18,18,209 (tax-free)
• Maturity Amount: ₹40,68,209
• Effective Wealth Gain: 80.8% over your total investment
• Total Tax Saved (80C at 30% slab): ₹7,02,000 over 15 years

Power of Extension: If you extend for another 5 years (total 20 years) with continued deposits of ₹1.5L/year, the maturity amount jumps to approximately ₹66.58 Lakhs. The compounding effect accelerates dramatically in the later years — Year 16 onwards, the interest earned per year exceeds your annual deposit.

PPF vs Other Tax-Saving Investments (Section 80C)

PPF Withdrawal Rules

Understanding PPF withdrawal rules is essential for financial planning:

• Complete Withdrawal: Only allowed after 15 years (maturity). The entire balance including principal and interest can be withdrawn tax-free.
• Partial Withdrawal: Allowed from the 7th financial year onwards. Maximum withdrawable amount is the lesser of: (a) 50% of the balance at the end of the 4th preceding year, or (b) 50% of the balance at the end of the immediately preceding year.
• Premature Closure: Allowed after 5 years only under specific circumstances — serious illness of the account holder, their spouse, or dependent children, or for higher education purposes. A penalty of 1% reduction in interest rate applies.
• Loan Facility: Available from the 3rd to 6th financial year. Maximum loan is 25% of the balance at the end of the 2nd preceding year. Interest rate is PPF rate + 1%.

Who Should Invest in PPF?

PPF is ideal for:

• Risk-averse investors who want guaranteed returns with zero risk to capital
• Salaried employees looking to maximize Section 80C deductions under the old tax regime
• Long-term retirement planners who want a disciplined, inflation-beating savings vehicle
• Parents who want to create a corpus for children's education or marriage (PPF can be opened in a minor child's name)
• Senior citizens who don't want market-linked risk and prefer sovereign guarantee

Not Ideal For: PPF is not suitable if you need liquidity within 7 years, are optimizing for maximum growth (equity ELSS funds have historically returned 12-15%), or are already in the new tax regime where 80C deductions are not available.
