Year-by-Year Breakdown
| Year | Yearly Deposit | Interest Earned | Closing Balance |
|---|
Interest is calculated on the minimum balance between the 5th and last day of each month and credited on 31 March. This projection assumes the full yearly deposit is made on or before 5 April each year; depositing later in the year earns less. Tenure is 15 years, then extensions in 5-year blocks. Actual values may vary.
What is a PPF Calculator?
A PPF (Public Provident Fund) calculator estimates the maturity value of your PPF account. At the 7.1% p.a. rate for Oct–Dec 2026, depositing ₹1.5 lakh a year for 15 years grows to about ₹40.7 lakh. Enter your yearly contribution, the interest rate and the tenure, and the calculator shows the total interest earned and the final corpus, all of it tax-free under the EEE (Exempt-Exempt-Exempt) framework.
PPF interest is compounded annually, with the rate notified quarterly by the government. The 15-year mandatory lock-in (extendable in 5-year blocks) suits money you won't need for a long time. It is most useful to conservative investors and to people in higher tax brackets who want a guaranteed, tax-free return. If you are saving for a daughter under 10, Sukanya Samriddhi Yojana is the closest alternative: it is also tax-free and pays 8.2% for Oct–Dec 2026, and the Sukanya Samriddhi calculator shows what it grows to.
Worked Example: ₹1.5 Lakh a Year for 15 Years
Illustrative: you deposit the maximum ₹1,50,000 on or before 5 April every year for the full 15-year term, at the 7.1% rate. These are the calculator's default inputs, so the figures above should match.
| Tenure | Total Invested | Interest Earned | Maturity Value |
|---|---|---|---|
| 15 years | ₹22,50,000 | ₹18,18,209 | ₹40,68,209 |
| 20 years | ₹30,00,000 | ₹36,58,288 | ₹66,58,288 |
| 25 years | ₹37,50,000 | ₹65,58,015 | ₹1,03,08,015 |
Over 15 years you put in ₹22.5 lakh and get back about ₹40.7 lakh, all tax-free. Extending by one 5-year block adds about ₹26 lakh, and a second block takes it past ₹1 crore, because the interest is now earned on a much larger balance.
The decision this informs is what to do at maturity. If you don't need the money, extending with contributions is usually worth more than withdrawing. The figures assume 7.1% holds throughout, which it may not, since the rate is revised quarterly.
How to Use This PPF Calculator
- 1
Enter your yearly contribution
PPF allows ₹500 minimum and ₹1,50,000 maximum per year. Investing the full ₹1.5 lakh gets the maximum deduction under Section 123 (read with Schedule XV) of the Income-tax Act, 2025 (formerly Section 80C; old tax regime only).
- 2
Set the interest rate
The default 7.1% is the government-notified rate for Oct–Dec 2026; it is revised quarterly. Test with a 7–8% range to account for potential rate changes over the long horizon.
- 3
Choose your tenure
PPF has a 15-year lock-in. After maturity you can extend it in 5-year blocks (apply within one year of maturity), so the calculator accepts 15, 20, 25 years and so on. Each extension earns interest on a larger balance, which is why the worked example above passes ₹1 crore at 25 years.
- 4
Review year-by-year growth
The breakdown table shows your closing balance each year, which helps you plan a loan (from Year 3) or a partial withdrawal (from Year 7). The limits are explained under Loan & Withdrawal Facility below.
Why Choose PPF for Long-Term Savings?
EEE Tax Benefit
Contributions qualify for deduction under Section 123 / Schedule XV of the Income-tax Act, 2025 (formerly 80C; old tax regime only), interest is tax-free, and the entire maturity amount is exempt.
Government Guaranteed
PPF is backed by the Government of India, so there is no credit risk. Your principal and interest are fully safe regardless of market conditions or bank failures.
Loan & Withdrawal Facility
From Year 3, take a loan against your PPF balance. Partial withdrawals are allowed from Year 7 (up to 50% of the lower of the balance at the end of the 4th preceding year or the preceding year), so you can meet an emergency without closing the account.
Attachment-Proof
PPF balances cannot be attached by courts or creditors, which matters most to self-employed people and business owners.
