Also known as: PPFcalculator, PPF maturity calculator,
Public Provident Fund calculator, PPF interest calculator
The Public Provident Fund (PPF) is a government-backed, tax-free savings scheme with a 15-year lock-in. Enter your yearly contribution to see how much your PPF account will be worth at maturity.
How to Use This PPF Calculator
- Enter the amount you invest per year (₹500 minimum to ₹1.5 lakh maximum).
- Check the current PPF interest rate (pre-filled, editable).
- Tap Calculate to see maturity value and total interest earned.
Formula
PPF grows by yearly compounding: each year's balance earns interest at the notified rate, and contributions up to ₹1.5 lakh per year qualify for Section 80C deduction.
Example: Investing ₹1,50,000 per year at 7.1% for 15 years grows to roughly ₹40.7 lakh — of which about ₹18.2 lakh is tax-free interest.
Frequently Asked Questions
▶ What is the PPF lock-in period?
PPF has a 15-year maturity. After that, you can extend the account in 5-year blocks with or without fresh contributions.
▶ Is PPF interest tax-free?
Yes — PPF enjoys EEE (exempt-exempt-exempt) status. The investment qualifies for 80C deduction, and both interest and maturity amount are completely tax-free.
▶ Can I withdraw from PPF before 15 years?
Partial withdrawals are allowed from the 7th year onward, subject to limits. Loans against PPF are available between the 3rd and 6th year.
▶ What is the minimum and maximum PPF investment?
You must invest at least ₹500 per year to keep the account active. The maximum eligible amount is ₹1.5 lakh per financial year.

Worked example with real numbers
₹1,50,000 invested every year for 15 years at 7.1%:
Because PPF interest is exempt, that ₹18.18 lakh is yours in full. An FD producing the same pre-tax amount would leave roughly ₹12.7 lakh after 30% tax.

Extending beyond 15 years
You can extend in five-year blocks indefinitely, with or without further contributions. Extending is where PPF gets genuinely powerful — a ₹1.5 lakh yearly contribution continued to 30 years grows to well over ₹1.5 crore, entirely tax-free.
The deposit-date trick worth knowing
PPF interest is calculated on the lowest balance between the 5th and the last day of each month. So a deposit made on the 6th earns nothing for that month.
- Depositing a lump sum before 5 April earns a full year's interest on it.
- Depositing monthly? Always do it before the 5th.
- Over 15 years, getting this right on a ₹1.5 lakh yearly contribution is worth roughly ₹80,000–1,00,000 in extra interest for no extra investment.
Rules, limits and tax treatment
- Minimum ₹500 a year, maximum ₹1,50,000 a year. Missing the minimum makes the account dormant, revivable with a small penalty.
- Tenure 15 years, extendable in 5-year blocks.
- Interest rate is declared quarterly by the government — currently 7.1%, and it has moved over the years.
- EEE status — contribution deductible (old regime), interest exempt, maturity exempt. Very few Indian products offer all three.
- Loan available between years 3 and 6, at a small spread over the PPF rate.
- Partial withdrawal permitted from year 7.
- Protection — the balance cannot be attached by a court decree for debt.
Important for the new regime: the 80C deduction on contributions is
not available under the new tax regime, which is now the default. The interest and maturity remain tax-free either way, so PPF is still attractive — but the upfront deduction may not apply to you. Check with our

Common mistakes
- Depositing after the 5th of the month and losing that month's interest.
- Assuming 7.1% is fixed for 15 years. It is revised quarterly.
- Exceeding ₹1.5 lakh in a year — the excess earns no interest and gets refunded.
- Opening multiple PPF accounts. One per person is the rule; extras get merged or closed.
- Counting the 80C deduction while filing under the new regime.
- Closing at 15 years out of habit, when extending compounds far better.
