What Is PPF Calculator?
A PPF calculator is a financial tool that estimates the maturity amount of your Public Provident Fund investment based on your annual deposit, the prevailing interest rate, and the investment tenure. It shows you the total corpus you will accumulate, the total interest your deposits will earn, and how each year's deposit compounds over the remaining tenure so you can plan your long-term savings with clarity.
- • Compare annual deposits: Compare different annual deposit amounts before committing to a yearly investment plan
- • Extension planning: Understand how extending PPF tenure beyond 15 years affects your final corpus
- • Tax-savings comparison: Evaluate PPF alongside ELSS, EPF, and other Section 80C instruments
- • Compound learning: Learn how government-backed compounding builds a tax-free retirement corpus
Unlike market-linked investments where returns fluctuate, PPF offers a fixed interest rate set by the Government of India, making it one of the most predictable long-term savings vehicles available to Indian residents. The PPF calculator removes the need for manual compound-interest math and gives you an instant projection of your investment growth.
If you are comparing PPF with equity-linked tax-saving options, the ELSS Calculator shows how market-linked returns compare against PPF's fixed rate.
How PPF Calculator Works
The PPF calculator uses the standard compound interest formula for annual investments made at the beginning of each financial year. It applies your annual deposit amount, the prevailing interest rate, and the investment tenure to project the total maturity value.
- P (Annual Deposit): Amount you deposit each financial year — can range from ₹500 to ₹1,50,000
- r (Interest Rate): Annual PPF rate set by the government, currently 7.1% per annum
- n (Tenure): Number of years the PPF account remains active, minimum 15 years for standard accounts
The (1 + r) factor at the end adjusts for deposits made at the start of each year, which is the standard strategy for investors who deposit before April 5 to earn interest for the full financial year.
Maximum Annual Contribution at Current Rate
You deposit ₹1,50,000 each year for 15 years at 7.1% interest, with contributions at the start of each financial year.
1. Rate as decimal: 7.1% = 0.071 2. Compute (1 + 0.071)^15 = 2.798 3. Subtract 1: 2.798 - 1 = 1.798 4. Divide by rate: 1.798 / 0.071 = 25.32 5. Multiply by (1 + rate): 25.32 × 1.071 = 27.12 6. Multiply by annual deposit: 1,50,000 × 27.12 = ₹40,68,000
After 15 years your ₹22,50,000 in total deposits grows to approximately ₹40,68,000 — with ₹18,18,000 in tax-free interest.
The maturity amount of ₹40,68,000 is the total value of your PPF account including principal and compounded interest. The total interest of ₹18,18,000 is entirely tax-free.
The official India Post PPF scheme page confirms that the PPF account matures after 15 financial years from the end of the year in which it was opened and can be extended indefinitely in blocks of 5 years with or without further contributions.
For salaried employees who already contribute to the Employee Provident Fund through payroll, the EPF Calculator helps compare total retirement savings including the employer match.
Key Concepts Explained
Understanding these four concepts helps you make better decisions about your PPF investment strategy.
Annual Compounding on Monthly Balances
PPF interest is calculated every month on the lowest balance in your account between the 5th and last day of that month. The interest is credited only once at the end of the financial year. Depositing before the 5th of April locks in your full year's deposit for maximum monthly interest calculation throughout the year.
EEE Tax Status Triple Exemption
PPF enjoys Exempt-Exempt-Exempt tax treatment under Section 80C of the Income Tax Act. Your deposits up to ₹1,50,000 per year are deductible from taxable income, the interest earned each year is not taxed, and the entire maturity amount is completely exempt from income tax. No other popular instrument offers this full triple exemption.
15-Year Lock-In with 5-Year Extensions
The standard PPF tenure is 15 years counted from the end of the financial year in which you opened the account. After maturity, you can extend the account indefinitely in 5-year blocks with or without making additional contributions. Extending with fresh deposits continues the Section 80C tax benefit.
Partial Withdrawal and Loan Provisions
From the 7th financial year onward, you can make one partial withdrawal per year up to 50% of the balance at the end of the 4th preceding year. Between the 3rd and 6th financial year, you can take a loan of up to 25% of the balance at 1% above the prevailing PPF rate.
To see how PPF's tax-free 7.1% compares against a taxable fixed deposit at a similar rate, the Fixed Deposit Calculator shows post-tax returns at your income slab.
How to Use This Calculator
Follow these steps to project your PPF corpus using the calculator.
- 1 Enter annual deposit: Input your planned annual deposit amount between ₹500 and ₹1,50,000.
- 2 Set interest rate: The current government rate of 7.1% is pre-filled. Adjust it for what-if scenarios or if the government revises rates.
- 3 Choose tenure: The standard PPF term is 15 years. Adjust up to 50 years to see extended period projections.
- 4 Review results: Check the maturity amount, total investment, and total interest in the results panel, then scroll to the year-wise breakdown table to see each year's opening balance, deposit, interest, and closing balance.
- 5 Compare scenarios: Adjust any input to compare different deposit amounts, tenures, or assumed interest rates side by side.
For a practical scenario, enter ₹1,00,000 as the annual deposit, keep 7.1% as the rate, and set tenure to 15 years. The calculator will show a maturity amount of approximately ₹27,12,000, with ₹15,00,000 in total deposits and ₹12,12,000 in tax-free interest.
For those considering mutual fund systematic investment plans alongside PPF, the SIP Calculator shows how monthly SIPs compound at market-linked rates for comparison.
Benefits of Using This Calculator
Using a PPF calculator helps you make informed decisions about your long-term savings strategy.
- • Plan 80C allocation: See exactly how much corpus a given annual deposit builds before the financial year ends, so you can decide your Section 80C contribution.
- • After-tax comparison: Compare PPF against taxable fixed deposits at similar rates. PPF's 7.1% is effectively higher than an FD's post-tax return for most tax brackets.
- • Visualize compounding: The year-wise breakdown shows how later years contribute exponentially more interest than early years, illustrating the power of long-term compounding.
- • Evaluate extensions: Assess whether extending PPF beyond 15 years with continued contributions is better than directing the same money into mutual funds or other instruments.
- • Avoid excess deposits: Check that your annual deposit stays within the ₹1,50,000 ceiling. Any excess does not earn PPF interest or qualify for 80C deduction.
Investors weighing PPF against the National Pension System for retirement can use the NPS Calculator to compare projected annuity and lump-sum payouts.
Factors That Affect Your Results
Several factors influence the final maturity amount of your PPF investment.
Annual Deposit Amount
Higher annual deposits produce proportionally larger maturity amounts, but you cannot exceed the ₹1,50,000 government cap. Deposits below ₹500 cause the account to become dormant.
Interest Rate Changes
The government reviews PPF rates quarterly. A rate change during your tenure affects future compounding. The calculator uses a constant rate for simplicity; actual returns may differ if rates move.
Deposit Timing Each Year
Depositing before the 5th of April ensures the full amount earns interest for all 12 months. Late deposits reduce the effective monthly balance on which interest is calculated for that year.
Tenure and Extension Choices
Extending PPF beyond 15 years with continued contributions boosts the final corpus significantly because the existing balance keeps compounding while new deposits add to the base each year.
- • This calculator assumes deposits are made at the beginning of each financial year. If you deposit later, actual interest earned will be lower since PPF interest is calculated on the minimum monthly balance between the 5th and last day.
- • The current 7.1% rate is applied for the full projection period. In reality, the government can raise or lower the rate quarterly. For long projections, run scenarios at slightly lower rates for a conservative estimate.
- • This calculator does not account for partial withdrawals or loans taken against your PPF balance, which would reduce the compounding base and lower the final maturity amount.
- • The year-wise breakdown shown in the results is an estimate based on the constant-rate assumption. Actual year-end balances depend on exact deposit timing and any rate changes during the period.
The Income Tax Department of India confirms that contributions up to ₹1,50,000 per financial year qualify for deduction under Section 80C, while the interest accrued and the maturity amount are entirely exempt from tax under the Exempt-Exempt-Exempt (EEE) category.

Frequently Asked Questions
Q: How is PPF interest calculated?
A: PPF interest is calculated every month on the lowest balance in your account between the 5th and last day of that month. The monthly interest is then compounded and credited to your account at the end of the financial year on March 31.
Q: What is the current PPF interest rate?
A: The current PPF interest rate is 7.1% per annum, unchanged since April 1, 2020. The rate is reviewed and set quarterly by the Ministry of Finance, Government of India, for all small savings schemes.
Q: Can I withdraw money from PPF before 15 years?
A: Yes, partial withdrawals are allowed from the 7th financial year onward. You can withdraw up to 50% of the balance at the end of the 4th preceding year, once per financial year. Complete account closure before 15 years is allowed only in special circumstances like medical emergencies or higher education, with a 1% interest penalty.
Q: Is PPF interest taxable?
A: No. PPF interest is completely tax-free under the Exempt-Exempt-Exempt (EEE) category. Your deposits qualify for Section 80C deduction, the interest earned each year is not taxable, and the entire maturity amount is exempt from income tax.
Q: What is the maximum amount I can invest in PPF per year?
A: The maximum deposit in a PPF account is ₹1,50,000 per financial year. The minimum required to keep the account active is ₹500 per year. Deposits above ₹1,50,000 do not earn PPF interest and are not eligible for Section 80C deduction.
Q: Can I extend my PPF account after 15 years?
A: Yes, you can extend your PPF account indefinitely in blocks of 5 years after the initial 15-year maturity. You can choose to extend with or without making additional contributions. Extending with contributions keeps the Section 80C tax benefit active for each extended block.
