The PPF maturity amount calculator shows exactly how much your Public Provident Fund account will grow by the end of 15 years. Enter your yearly deposit, and the tool does all the maths for you — no spreadsheet needed.
A PPF maturity amount calculator is an online tool that computes the total corpus you will receive at the end of your 15-year PPF tenure, based on your annual deposit and the current interest rate.
PPF — Public Provident Fund — is a government-backed savings scheme. You deposit money every year, earn compound interest, and get the full amount tax-free at maturity. The Income Tax Department’s PPF page confirms that deposits qualify for deduction under Section 80C up to ₹1.5 lakh per year.
Doing this calculation manually is painful — 15 years of compounding is not simple arithmetic. That is exactly why a PPF maturity amount calculator exists. It saves you time and shows the full picture in under ten seconds.
The government uses a specific formula to calculate PPF interest every month but credits it annually. Here is the formula:
📐 Formula: F = P × [((1 + i)^n − 1) / i] × (1 + i)
Where:
F = Maturity amount
P = Annual deposit amount
i = Annual interest rate (currently 7.1% = 0.071)
n = Number of years (minimum 15)
The (1 + i) multiplier at the end is because PPF deposits made at the beginning of the financial year (before 5th April) earn interest for the full year. Deposit late and you lose one month’s interest. Small habit, big difference over 15 years.
The current PPF interest rate is 7.1% per annum, set by the Ministry of Finance. You can check the latest rate on the RBI’s small savings rates page. Rates are reviewed quarterly but have been stable at 7.1% since April 2020.
Below are three ready-made scenarios from the PPF maturity amount calculator at 7.1% for 15 years. These are the numbers most Indian families ask about.
| Yearly Deposit | Total Invested | Interest Earned | Maturity Amount |
|---|---|---|---|
| ₹50,000 | ₹7,50,000 | ₹6,06,000 | ₹13,56,070 |
| ₹1,00,000 | ₹15,00,000 | ₹12,12,000 | ₹27,12,139 |
| ₹1,50,000 | ₹22,50,000 | ₹18,18,209 | ₹40,68,209 |
Notice the pattern. You invest ₹22.5 lakh and walk away with ₹40.68 lakh. That is ₹18+ lakh in free interest — all tax-free. No mutual fund gives you that kind of certainty with zero tax on gains.
Also note: if you deposit ₹1.5 lakh every year, you save ₹46,800 in taxes annually (at 31.2% tax slab). Over 15 years, that is almost ₹7 lakh in tax savings on top of the maturity amount. The PPF maturity amount calculator does not show this — but it is real money back in your pocket.
Here is how a ₹1,50,000 per year deposit grows over 15 years at 7.1%. This is the opening balance at the start of each year.
| Year | Deposit | Interest | Closing Balance |
|---|---|---|---|
| 1 | ₹1,50,000 | ₹10,650 | ₹1,60,650 |
| 3 | ₹1,50,000 | ₹34,119 | ₹5,14,660 |
| 5 | ₹1,50,000 | ₹59,773 | ₹9,00,978 |
| 10 | ₹1,50,000 | ₹1,34,207 | ₹20,27,424 |
| 15 | ₹1,50,000 | ₹2,20,604 | ₹40,68,209 |
See how the interest in Year 15 is almost 15× the interest in Year 1. That is compounding doing its job. The longer you stay, the harder your money works. This is why extending your PPF beyond 15 years — in 5-year blocks — is almost always a good idea.
The PPF maturity amount calculator gives you a number — but that number can shift based on a few real-world factors. Know these before you plan.
Small changes in habits lead to big changes in the final number. Here are the ones that actually matter.
Not just before the 5th — on April 1st. This earns you interest for the entire financial year. Over 15 years, this one habit adds close to ₹1–1.5 lakh extra to your corpus compared to depositing in October or later.
The tax deduction under Section 80C goes up to ₹1.5 lakh. Your PPF deposit fills this limit and earns compounding interest. It is one of the few investments where you get a tax break on the way in and the money is tax-free on the way out. If your salary is ₹8–15 lakh, this one move reduces your tax bill meaningfully. Pair it with a tax saving calculator to see the combined impact.
Many people close their PPF account at 15 years and spend the corpus. But if you extend by 5 more years with fresh deposits, the compounding acceleration is remarkable. Use our PPF extension calculator to see the extended maturity amount.
Parents can open a PPF account for a minor child. The deposits count under the parent’s ₹1.5 lakh limit — but the child gets a separate account that matures when they are 18–20 years old. Good for education planning. Check the education planning calculator to match the corpus to future fees.
Tax calculations are indicative. Consult a CA for your situation.
A: The PPF maturity amount calculator shows three numbers: your total investment over 15 years, the total interest earned through compounding, and the final maturity corpus. For a ₹1.5 lakh/year deposit at 7.1%, the maturity amount is approximately ₹40.68 lakh. All three figures are tax-free under the EEE (Exempt-Exempt-Exempt) status of PPF.
A: The PPF maturity amount calculator is highly accurate when the interest rate stays constant. It uses the official compounding formula prescribed by the Ministry of Finance. The only variable is future interest rate changes — the government reviews rates quarterly. If the rate changes, your actual maturity amount will differ slightly from the calculator’s output.
A: Yes. Most PPF maturity amount calculators let you change the tenure from 15 to 20 or 25 years. After the 15-year lock-in, you can extend in 5-year blocks. You can choose to keep depositing (active extension) or just let the existing balance compound without fresh deposits (passive extension). Both options are available in a good PPF calculator.
A: Yes. PPF enjoys EEE tax status. The deposit qualifies for Section 80C deduction (up to ₹1.5 lakh/year), the annual interest is tax-free, and the maturity amount is completely tax-free. This is different from FDs or NSC where the interest is taxable. The PPF maturity amount calculator does not deduct any tax from the final figure — because there is none to deduct.
A: You can open a PPF account at any nationalised bank (SBI, Bank of Baroda, PNB), select private banks (HDFC, ICICI, Axis), or at the post office. All accounts earn the same government-set interest rate — currently 7.1%. The calculator results apply equally to all. Online PPF accounts at SBI or HDFC let you deposit digitally before the 5th of April for maximum interest.
