PPF Calculator India – Public Provident Fund Maturity & Tax-Free Returns
Investing the maximum ₹1,50,000 per year at 7.1% interest rate for 15 years builds a tax-free corpus of approximately ₹40.68 lakh – of which ₹18.18 lakh is pure interest earned through the power of compounding. Extend the same investment for 25 years, and the corpus grows to ₹1.03 crore with ₹65.58 lakh in interest. The longer you stay, the more compounding works in your favour.
What is Public Provident Fund (PPF)?
The Public Provident Fund is a long-term savings scheme backed by the Government of India with a sovereign guarantee, making it one of the safest investment options available to Indian residents. Established under the Public Provident Fund Act, 1968, PPF is administered by the Ministry of Finance and available through designated banks (SBI, HDFC, ICICI, PNB, and others) as well as post offices across India.
PPF is specifically designed for individuals looking for a risk-free, tax-efficient investment with guaranteed returns. The scheme has a mandatory lock-in period of 15 years, which enforces long-term savings discipline – a critical factor for goals like retirement planning, children’s education funding, or building a debt-free emergency corpus.
Unlike market-linked instruments such as NPS or mutual funds, PPF offers a fixed interest rate that is reviewed and declared by the government every quarter under the Small Savings Scheme framework. This predictability makes PPF ideal for conservative investors and those in higher tax brackets who benefit most from the EEE (Exempt-Exempt-Exempt) tax advantage.
PPF Maturity Calculation Formula
The maturity value of your Public Provident Fund account depends on your annual contribution, the prevailing interest rate, and the total investment duration. The formula mirrors the future value of an annuity:
Annual deposit: ₹1,50,000 | Rate: 7.1% | Duration: 15 years
Maturity: ₹1,50,000 × ((1.071^15 − 1) ÷ 0.071) = ₹40,68,209
Total invested: ₹22,50,000 | Interest earned: ₹18,18,209
The “Deposit Before 5th” Rule
A critical detail most investors overlook: PPF interest is calculated on the lowest balance between the 5th and last day of each month. If you deposit your contribution after the 5th, you lose interest on that amount for the entire month. For maximum returns, always deposit on or before April 5th (for yearly lump sum) or before the 5th of each month (for monthly SIP contributions).
PPF Interest Rate History (2014–2026)
The PPF interest rate has gradually declined over the past decade as the government aligned small savings scheme rates with market yields. Here is the historical trend:
| Period | Interest Rate | Trend |
|---|---|---|
| Q4 FY 2025-26 | 7.1% | N/A |
| Q1 FY 2020-21 to present | 7.1% | Stable for 6 years |
| FY 2019-20 | 7.9% → 7.1% | ▼ Cut mid-year |
| FY 2018-19 | 8.0% → 7.6% | ▼ |
| FY 2017-18 | 7.8% → 7.6% | ▼ |
| FY 2016-17 | 8.1% | ▼ |
| FY 2015-16 | 8.7% | ▼ |
| FY 2014-15 | 8.7% | N/A |
Despite the rate reduction from 8.7% to 7.1%, PPF remains competitive because of its tax-free status. A 7.1% tax-free return is equivalent to approximately 10.1% pre-tax return for someone in the 30% tax bracket – significantly better than most taxable fixed deposits.
PPF Withdrawal and Loan Rules
Although PPF has a 15-year lock-in, the scheme provides partial liquidity options during the investment period:
| Facility | Available From | Maximum Amount | Interest Rate |
|---|---|---|---|
| Loan against PPF | 3rd to 6th year | 25% of balance at end of 2nd preceding year | PPF rate + 1% |
| Partial withdrawal | 7th year onwards | 50% of balance at end of 4th preceding year | N/A (your money) |
| Premature closure | After 5 years (special cases) | Full balance minus 1% interest penalty | Reduced by 1% |
| Account extension | After 15 years | Continue with/without deposits, 5-year blocks | Prevailing PPF rate |
Premature closure is permitted only for specific reasons: life-threatening illness of account holder or dependent, higher education of account holder or children, or change in residency status (becoming NRI).
PPF vs Other Investments: Real Returns Comparison
The true measure of any investment is the real (inflation-adjusted) return after taxes. Here is how PPF compares to other popular options in India for long-term wealth creation:
| Investment | Nominal Return | Post-Tax (30% slab) | Real Return (after 6% inflation) | Risk Level |
|---|---|---|---|---|
| PPF | 7.1% | 7.1% (tax-free) | +1.0% | Zero (sovereign guarantee) |
| Bank FD (5yr) | 7.0% | 4.9% | −1.1% | Very low |
| EPF | 8.25% | 8.25% (below ₹2.5L) | +2.1% | Zero |
| NPS (Equity) | 10-12% | 8-10% | +2 to +4% | Moderate-High |
| ELSS Mutual Funds | 12-15% | 10-13% (LTCG 12.5%) | +4 to +7% | High |
| Sukanya Samriddhi (SSY) | 8.2% | 8.2% (tax-free) | +2.1% | Zero |
Inflation reality check: At the current 7.1% PPF rate with 6% average inflation, your real return is approximately 1%. This means your PPF corpus doubles in purchasing power every ~72 years. For long-term goals like retirement, supplement PPF with equity exposure through SIP investments or NPS equity allocation to genuinely beat inflation.

PPF for Different Life Stages
- Young earners (22-30): Open a PPF account early to maximize the 15-year compounding runway. Even ₹500/month builds the savings habit. The Section 80C deduction provides immediate tax relief while building a sovereign-guaranteed safety net alongside riskier equity investments
- Mid-career (30-45): Max out the ₹1.5 lakh annual limit. PPF serves as the fixed-income anchor in your portfolio, complementing equity SIPs and EPF contributions. Consider opening a PPF account for your minor child for additional tax-free compounding
- Pre-retirement (45-55): If your PPF is maturing, extend it in 5-year blocks with continued contributions. The guaranteed tax-free returns provide stability as you gradually shift from equity to debt allocation. Compare with your retirement corpus requirements
- Parents: PPF for minors allows parents to build a long-term education fund with sovereign guarantee. However, the ₹1.5 lakh limit is combined across parent and minor accounts. For daughters specifically, consider the Sukanya Samriddhi Yojana which offers a higher 8.2% rate
Section 80C Tax Optimization with PPF
PPF contributions qualify for deduction under Section 80C of the Income Tax Act, up to ₹1.5 lakh per financial year. For taxpayers in the 30% bracket (plus cess), this translates to an effective tax saving of approximately ₹46,800 per year. Combined with the tax-free interest and maturity, PPF delivers a pre-tax equivalent return of over 10% for high-income earners.

PPF Calculator Questions Answered
What is the current PPF interest rate in India?
The current PPF interest rate is 7.1% per annum, effective since Q1 FY 2020-21. The rate is reviewed quarterly by the Government of India under the Small Savings Scheme framework. Interest is compounded annually but calculated on the monthly running balance between the 5th and last day of each month.
What is the maximum amount I can invest in PPF per year?
The maximum deposit limit for a Public Provident Fund account is ₹1,50,000 per financial year. The minimum annual deposit is ₹500. Deposits can be made in a lump sum or in up to 12 monthly instalments. Any amount deposited above ₹1.5 lakh will not earn interest and is not eligible for Section 80C tax deduction.
How is PPF maturity amount calculated in India?
PPF maturity is calculated using the compound interest formula: M = P × [((1+r)^n – 1) / r] where P is the annual deposit, r is the annual interest rate, and n is the number of years. Interest is computed monthly on the lowest balance between the 5th and last day of the month, but credited annually on March 31st. For maximum returns, deposit your contribution on or before the 5th of April each year.
Is PPF interest completely tax-free in India?
Yes, PPF enjoys EEE (Exempt-Exempt-Exempt) tax status in India. The investment qualifies for deduction under Section 80C (up to ₹1.5 lakh), the interest earned throughout the tenure is fully tax-exempt, and the entire maturity amount is tax-free. This makes PPF one of the most tax-efficient savings instruments available to Indian residents.
Can I withdraw money from PPF before 15 years?
Partial withdrawals from a PPF account are allowed from the 7th financial year onwards (after completing 6 years). The maximum withdrawal amount is 50% of the balance at the end of the 4th year or the preceding year, whichever is lower. Additionally, loans against PPF balance are available from the 3rd to 6th financial year at an interest rate of 1% above the PPF rate. Premature closure is allowed only in specific circumstances like serious illness, higher education, or change of residency status.
Can I extend my PPF account after 15 years?
Yes, after the mandatory 15-year lock-in period, you can extend your PPF account in blocks of 5 years indefinitely. Extension can be with or without fresh contributions. If you extend with contributions, you continue to earn interest and get Section 80C benefits. If you extend without contributions, the existing balance continues to earn interest at the prevailing rate. The extension request must be submitted within one year of maturity.
How does PPF compare to NPS and EPF for retirement planning?
PPF offers guaranteed 7.1% tax-free returns with sovereign guarantee, making it the safest option. NPS provides market-linked returns of 9-12% with higher growth potential but partial taxability and mandatory annuity purchase. EPF offers 8.25% with employer matching but is only available to salaried employees. For inflation-adjusted real returns, NPS equity allocation (4-6% real return) outperforms PPF (approximately 1% real return at 6% inflation). A balanced retirement strategy typically combines all three instruments.
Can NRIs invest in PPF in India?
NRIs cannot open new PPF accounts in India. However, PPF accounts opened before becoming an NRI can be maintained until maturity (15 years from the date of opening). After maturity, NRI accounts cannot be extended. The interest rate applicable is the same as for resident Indians. For NRI-specific investment options, consider NRE/NRO fixed deposits or NPS (NRI tier).
