PPF Calculator — Public Provident Fund Returns
Calculate PPF maturity value, year-by-year growth, and tax savings instantly at India's current 7.1% rate.
Our free PPF Calculator helps Indian investors instantly compute their Public Provident Fund maturity amount, total interest earned, and annual Section 80C tax savings based on the current GOI rate of 7.1% p.a. Enter your monthly or annual investment, set your tenure from 15 to 50 years, and see a full year-by-year breakdown with an interactive growth chart. Unlike most calculators, iToolVerse also shows inflation-adjusted real returns and allows you to model post-maturity 5-year extension scenarios.

Section 80C tax saved every year
Your deductible PPF contribution is ₹1,50,000 per year (capped at the ₹1.5 lakh 80C limit). Here is the income tax you save annually at each slab — PPF is fully tax-free on interest and maturity too (EEE).

Lock-in, withdrawals & extension
PPF has a 15-year lock-in. Partial withdrawals are allowed from the start of year 7, capped at 50% of the balance at the end of the 4th preceding year. On your numbers, the indicative maximum withdrawal at the start of year 7 would be about ₹2,58,489.
After 15 years you can withdraw fully, keep the balance earning interest, or extend in 5-year blocks (with or without fresh deposits). Set the tenure above to 20, 25 or 30 years to model an extended account — most of the interest is earned in these later years.

Maturity value
₹40,68,209
Estimates are indicative and assume a constant annual interest rate compounded once a year on the year's full deposit. The actual PPF rate is revised quarterly by the Government of India, and real interest depends on your deposit timing within the year. The 80C tax savings and inflation figures are simplified estimates, not tax or investment advice.
What a monthly PPF deposit grows into
Estimated maturity value at the current 7.1% rate (annual compounding). ₹12,500 a month is the ₹1.5 lakh statutory maximum. Your own numbers may differ — use the calculator above to model them.

PPF calculator guide
What the Public Provident Fund actually does to your money, the rules that govern it, and how to read the maturity, interest and tax figures this calculator gives you.
What is the PPF?
The Public Provident Fund (PPF) is a government-backed, long-term savings scheme open to every Indian resident. You can deposit between ₹500 and ₹1,50,000 per financial year, the balance earns a government-set interest rate (currently 7.1% p.a., compounded annually), and the entire corpus matures tax-free after a 15-year lock-in. Because the principal, the interest and the maturity amount are all exempt from tax, PPF carries the coveted EEE (Exempt-Exempt-Exempt) status.
Why the later years matter most
PPF interest is credited once a year and then earns interest itself the following year. In the early years most of your balance is the money you put in; but as the account ages, the interest portion compounds and eventually overtakes your contributions. That crossover — visible in the year-by-year chart above — is exactly why extending a PPF account beyond 15 years is so powerful.
The rules that shape your corpus
Quarterly rate
The Government of India reviews the PPF rate every quarter. It has historically sat between ~7% and 8%. Edit the rate field to see how a future revision changes your maturity.
15-year lock-in
Your money is locked for 15 years (from the end of the financial year you open the account). A loan is available in years 3-6 and partial withdrawals from year 7.
₹1.5 lakh 80C limit
Contributions up to ₹1,50,000 a year are deductible under Section 80C — a limit shared with EPF, ELSS, life-insurance premiums and other instruments.
5-year extensions
After maturity you can extend the account in 5-year blocks, with or without fresh deposits, and keep earning tax-free interest indefinitely.
Monthly vs. yearly deposits
Most people think in monthly terms, but PPF interest is always computed on the annual balance. Switch to the Monthly tab and the calculator multiplies your figure by 12 to get the yearly contribution — so ₹12,500 a month maps to the ₹1,50,000 maximum. Depositing earlier in the financial year earns marginally more real interest, but the year-end maturity is the same under the standard annual model.
