PPF Calculator

By Varun M

Enter your annual PPF contribution and tenure to see your maturity value at the current 7.1% rate — pre-filled, but editable, since PPF's rate is revised every quarter and can change over a 15-year account life.

Annual contribution (₹) Capped at ₹1,50,000/year — the statutory maximum. Anything above earns no interest and gets no tax benefit. Annual interest rate (%) Pre-filled with the current Jul–Sep 2026 rate. Government-revised every quarter — edit this if you're modelling a longer period where it may change. Tenure (years) Minimum lock-in is 15 years, extendable after that in blocks of 5.

Enter a valid contribution, rate, and tenure (at least 1 year) to see your maturity value.

How to use this calculator

Enter how much you plan to contribute each year (up to the ₹1,50,000 statutory maximum), the interest rate, and your tenure. The rate is pre-filled with the current government rate but is fully editable — useful since PPF accounts run for 15+ years and the rate is revised every quarter, so it won't stay 7.1% for your entire tenure.

The formula, explained

PPF interest compounds annually, credited at the end of each financial year. This calculator assumes your full annual contribution is deposited at the start of the year (by 5 April) — the maximum-interest scenario, since PPF interest is calculated monthly on the lowest balance between the 5th and the last day of each month. Depositing after the 5th means that month's contribution doesn't start earning interest until the following month, so contributing in smaller instalments later in the year, or after the 5th, will earn somewhat less than shown here.

Worked example

₹1,50,000/year (the maximum), at 7.1%, over the standard 15-year tenure:

Total invested: ₹22,50,000
Maturity value: ₹40,68,209
Total interest earned: ₹18,18,209 — more than 80% of what you invested

Key rules

Minimum ₹500, maximum ₹1,50,000 per financial year. Contributions above ₹1,50,000 earn no interest and get no tax benefit.
15-year minimum lock-in, extendable indefinitely thereafter in blocks of 5 years.
Interest rate is set by the Ministry of Finance every quarter (January, April, July, October) — it is not fixed for the life of your account.
PPF falls under the EEE (Exempt-Exempt-Exempt) tax category: contributions, interest, and maturity proceeds are all tax-free under the old regime's Section 80C rules (Income-tax Act, 1961 — renumbered Section 123 under the Income-tax Act, 2025 from Tax Year 2026-27; Section 80C still applies for AY 2026-27 filings).

PPF vs. SIP

PPF gives you a government-guaranteed, tax-free return with no market risk, but a 15-year lock-in and a ₹1,50,000/year ceiling. A SIP into a mutual fund carries market risk and no guaranteed return, but has historically offered higher long-run growth with no fixed investment cap. They're not mutually exclusive — many people use PPF for a guaranteed core and SIPs for additional growth.

FAQ

7.1% per annum, compounded annually, for the July–September 2026 quarter — unchanged since 1 April 2020. The Ministry of Finance revises this rate every quarter (January, April, July, October), so check for updates rather than assuming it stays the same.

Minimum ₹500, maximum ₹1,50,000 per financial year. You can deposit more than ₹1,50,000, but the excess earns no interest and gets no tax benefit under Section 80C.

PPF interest is calculated monthly on the lowest balance between the 5th and the last day of that month. If you deposit after the 5th, that amount doesn't start earning interest until the following month. Depositing your full annual contribution by 5 April each year maximises your interest for the year.

Partial withdrawal is allowed from the 7th financial year onwards, subject to specific limits. Premature closure is allowed only in limited cases (e.g. medical emergencies, higher education), also with conditions and often a reduced interest rate. This calculator shows the maturity value assuming no withdrawals.

No — PPF is an EEE (Exempt-Exempt-Exempt) investment: your contribution is deductible under Section 80C (old regime only), the interest earned is tax-free, and the maturity amount is tax-free too.

You can withdraw the full maturity amount, or extend the account in blocks of 5 years — either continuing to contribute, or keeping it open without further contributions while it continues earning interest on the existing balance.

This is an indicative estimate. It assumes your full annual contribution is deposited by 5 April each year (the maximum-interest scenario) — later or split deposits earn somewhat less. PPF's interest rate is revised every quarter and will not stay fixed for a full 15-year tenure; the rate field is editable for exactly this reason. Confirm your account's exact interest and maturity value with your bank or post office before making financial decisions.
