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.
Questions people ask
Short answers on PPF Calculator. Tap a question to open it.
01What is the PPF and how does it work?
A 15-year government-backed savings scheme. You can deposit between ₹500 and ₹1,50,000 a year, interest is credited annually at the notified rate, and the whole balance is paid out on maturity. The term can be extended in blocks of five years.
02Is PPF completely tax free?
Yes. It falls in the exempt-exempt-exempt category — the deposit qualifies under section 80C, the interest is exempt, and the maturity proceeds are exempt. The 80C deduction is available only under the old regime, but the interest and maturity exemption applies regardless of regime.
03When should I deposit to maximise interest?
Interest is calculated on the lowest balance between the 5th and the last day of each month. Depositing on or before the 5th of the month — and ideally the full year's contribution by 5 April — earns the most interest.
04Can I withdraw from PPF before 15 years?
A partial withdrawal is allowed from the seventh year, limited to 50% of the balance at the end of the fourth preceding year. A loan is available between the third and sixth years. Premature closure is permitted only on specified grounds after five years.
05Can I open a PPF account for my child?
Yes, as a guardian, but the combined deposit across your own and the minor's account cannot exceed ₹1,50,000 a year. There is no separate limit for the child.
06What is the current PPF interest rate?
The PPF interest rate is set by the Ministry of Finance each quarter. As of Q1 FY 2025-26, the rate is 7.1% per annum, compounded annually. Despite quarterly reviews, the PPF rate has remained at 7.1% since April 2020. Interest is calculated on the minimum balance between the 5th and last day of each month.
07What is the maximum and minimum contribution to PPF per year?
Minimum annual contribution is Rs 500 per year (failure to contribute causes account to become dormant, revivable on Rs 50 penalty per year). Maximum contribution is Rs 1,50,000 per financial year. Contributions above Rs 1.5 lakh earn no interest on the excess and are returned without interest.
08Can I extend my PPF account after the 15-year maturity?
Yes. PPF can be extended in blocks of 5 years after the initial 15-year maturity. Extensions can be with or without fresh contributions. If extended with contributions, the entire corpus continues earning interest and one withdrawal per year is allowed. Extensions must be applied for within one year of maturity.
09Can a Hindu Undivided Family (HUF) open a PPF account?
No. HUFs are not permitted to open PPF accounts. Only individuals (including minors through guardians) can open PPF accounts. Each individual can have only one PPF account (plus one for a minor child as guardian). NRIs cannot open new PPF accounts but can continue existing ones until maturity.
