We map PPF, ELSS, NPS and insurance to save the most tax — and file your ITR right.
Disclaimer: Indicative estimate assuming a full deposit at the start of each year and annual compounding at a constant rate. Actual PPF interest is credited yearly on the lowest balance between the 5th and month-end, and the rate is revised quarterly by the Government.
Why PPF is a tax-free compounding machine
The Public Provident Fund is a Government-backed small-savings scheme with a 15-year lock-in. It carries the rare EEE status — your deposit is deductible under Section 80C, the interest each year is exempt, and the entire maturity amount is tax-free. At today's rate, a maxed-out account compounds into a substantial, completely tax-free corpus.
How PPF maturity is calculated
PPF interest is compounded once a year. Each year the calculator adds your deposit to the running balance, then applies the annual interest rate on the total. The formula for every year is simply:
| Balance after year | (Balance + Deposit) × (1 + r) |
| Interest this year | (Balance + Deposit) × r |
| Total invested | Deposit × Years |
| Total interest | Maturity − Invested |
| Yearly deposit | ₹1,50,000 |
| Total invested (15 yrs) | ₹22,50,000 |
| Interest earned | ≈ ₹18,18,209 |
| Maturity value | ≈ ₹40,68,209 |
What a maxed-out account becomes
Depositing the full ₹1,50,000 every year at 7.1% and extending the account shows the power of long compounding. Each 5-year extension dramatically increases the tax-free corpus:
Key terms explained
EEE tax status
PPF is Exempt-Exempt-Exempt: the deposit is deductible u/s 80C, the annual interest is exempt, and the final maturity amount is fully tax-free. Very few instruments in India enjoy this triple exemption.
Annual compounding
Interest is calculated and added once a year. Because each year's interest itself earns interest in future years, the balance grows faster the longer you stay invested — the classic compounding curve.
15-year lock-in & extension
A PPF account matures after 15 financial years. You can then extend it in blocks of 5 years, any number of times, either with fresh deposits or by just letting the balance keep earning interest.
₹1.5 lakh limit
The most you can deposit in a PPF account in one financial year is ₹1,50,000, and the minimum is ₹500. This same ₹1.5L is your total 80C ceiling shared with ELSS, EPF, life insurance and more.
