Assumes a constant 7.1% annual rate, compounded yearly, with the full deposit made at the start of each year. The yearly deposit is capped at the ₹1.5 lakh statutory limit. PPF's official rate is revised quarterly by the government — verify before relying on this.

How it works
The Public Provident Fund (PPF) is a government-backed long-term savings account open to any resident Indian. You deposit between ₹500 and ₹1.5 lakh per financial year, the balance earns a government-notified rate compounded annually, and the account matures after 15 years — extendable indefinitely in 5-year blocks, with or without fresh deposits.
This calculator projects the maturity value assuming the full deposit is made at the start of each year, compounding yearly at a constant rate. It defaults to 7.1% — the notified PPF rate as of the Apr–Jun 2026 quarter, revised quarterly by the government — with the rate and the tenure (15 to 30 years) both editable.
PPF is EEE: the deposit qualifies for Section 80C, and interest and maturity proceeds are entirely tax-free. That makes its effective pre-tax yield considerably higher than the headline rate for anyone in the top tax slabs, which is why it remains the default debt allocation for many Indian households.
M = A × [(1+r)^n − 1]/r × (1+r)A is the yearly deposit, r the annual rate as a decimal, n the number of years. The (1+r) multiplier reflects deposits made at the start of each year (an annuity-due), which is how this calculator models it.
Frequently asked questions
Is PPF interest taxable?
No. PPF enjoys exempt-exempt-exempt (EEE) status: deposits up to ₹1.5 lakh a year qualify for deduction under Section 80C, the annual interest is completely tax-free, and the maturity amount is tax-free too. PPF interest also does not need to be reported as taxable income, though it appears as exempt income in the return.
What is the current PPF interest rate?
The PPF rate is notified by the government every quarter. As of the Apr–Jun 2026 quarter it was 7.1% per year, compounded annually — the default this calculator uses, editable via the rate slider. Interest is calculated monthly on the lowest balance between the 5th and the end of the month, and credited once a year.
Can I withdraw from PPF before 15 years?
Partially. From the 7th financial year, one partial withdrawal per year is allowed, capped at 50% of the balance at the end of the 4th preceding year or the preceding year, whichever is lower. Loans against the balance are available from the 3rd to the 6th year. Full premature closure is permitted after 5 years only for specific reasons (serious illness, higher education, change of residency status) with a 1% interest penalty.
What happens to PPF after 15 years?
You have three options at maturity: withdraw the full balance tax-free; extend the account in 5-year blocks with fresh deposits (requires a form within one year of maturity); or extend without deposits, in which case the balance simply keeps earning interest and one withdrawal a year is allowed. Extensions can be repeated indefinitely — this calculator's tenure slider goes up to 30 years to model that.
What are the minimum and maximum PPF deposits?
The minimum is ₹500 per financial year and the maximum ₹1.5 lakh per financial year, the cap this calculator enforces. Deposits above the cap earn no interest and no 80C benefit. Failing to deposit the minimum marks the account discontinued; it can be revived with a ₹50 fee per defaulted year plus the ₹500 arrears.
Is depositing before the 5th of the month better?
Yes. PPF interest for a month is computed on the lowest balance between the 5th and the last day of the month, so a deposit made after the 5th earns nothing for that month. Depositing the full year's amount before April 5th maximises interest — which is also the assumption (deposit at the start of the year) this calculator uses.
