PPF Maturity Calculator

Enter your annual deposit, tenure and interest rate. The calculator assumes deposits made at the start of each year (annuity due), matching how PPF interest compounds when you deposit before 5 April.

Min ₹500 — Max ₹1,50,000 per year
Min 15 years. Extensions in 5-year blocks (up to 50)
Current rate: 7.1% (Q1 FY 2026-27)
Deposit before 5 April to maximise interest

PPF interest is calculated on the lowest balance between the 5th and the last day of each month. Depositing your full annual amount before 5 April earns you a full year of interest on the whole sum.

The formula

How PPF Interest Is Calculated

PPF interest is calculated on the minimum balance between the 5th and the last day of each month, compounded annually and credited to the account on 31 March each year. The calculator uses the future-value of an annuity-due formula:

Maturity = PMT × (((1 + r)n − 1) / r) × (1 + r)   where PMT = annual deposit, r = rate ÷ 100, n = number of years.

PPF Calculator — Frequently Asked Questions

Rate & returns
What is the PPF interest rate for 2025-26?
The PPF interest rate for Q1 FY 2026-27 (April–June 2026) is 7.1% per annum, compounded annually. This rate has remained unchanged since April 2020. The government reviews small-savings rates every quarter. Interest is calculated on the lowest balance between the 5th and the last day of each month, and credited at the end of the financial year (31 March).
How is PPF maturity amount calculated?
Maturity uses the future-value-of-annuity-due formula: Maturity = PMT × (((1 + r)^n − 1) / r) × (1 + r), where PMT is the annual deposit, r is the rate ÷ 100 and n is the number of years. This calculator assumes deposits are made at the start of each year, which is how you maximise interest by depositing before 5 April.
How much will I get if I invest ₹1.5 lakh a year for 15 years?
At a constant 7.1%, investing ₹1,50,000 a year for 15 years (deposits at start of year) gives a maturity of roughly ₹40.68 lakh — about ₹22.5 lakh invested and ₹18.18 lakh interest, entirely tax-free. Actual returns vary as the rate is revised each quarter.
When is PPF interest credited?
Interest is compounded annually and credited to your account on 31 March each financial year. It is calculated monthly on the lowest balance between the 5th and the last day of the month, so a deposit made after the 5th earns no interest for that month.
Deposits & limits
What is the minimum and maximum PPF deposit?
The minimum deposit is ₹500 per financial year (to keep the account active) and the maximum is ₹1,50,000 per financial year. Deposits above ₹1.5 lakh earn no interest and are not eligible for tax deduction. You can deposit in a lump sum or in instalments.
What happens if I miss the minimum ₹500 deposit?
The account becomes inactive. To revive it, deposit ₹500 for each missed year plus a ₹50 penalty per defaulted year. An inactive account cannot be used for loans or partial withdrawals until it is regularised.
Tax
Is PPF maturity amount taxable?
No. PPF follows the EEE (Exempt-Exempt-Exempt) model. The annual contribution is deductible under Section 80C (up to ₹1.5 lakh), the interest earned each year is fully tax-free, and the maturity amount (principal + interest) is completely exempt from income tax. PPF is one of the very few investments exempt at all three stages.
Does PPF qualify for Section 80C in the new tax regime?
The PPF deduction under Section 80C is available only under the old tax regime. Under the new (default) regime, most 80C deductions including PPF are not allowed, though the interest and maturity remain tax-free in both regimes. Choose the old regime if your 80C investments (PPF, ELSS, LIC, etc.) make it more beneficial.
Rules
What is the PPF lock-in period?
PPF has a mandatory 15-year lock-in from the end of the financial year in which the account is opened. After 15 years you can withdraw the full amount, or extend in blocks of 5 years — with or without further contribution.
When can I make a partial withdrawal from PPF?
Partial withdrawal is allowed from the 7th financial year onwards, once per year. You can withdraw up to 50% of the balance at the end of the 4th year preceding the withdrawal, or the balance at the end of the immediately preceding year, whichever is lower.
How do I extend PPF after 15 years?
You have two options: (1) Extension without contribution — the account keeps earning interest with no deposits, and one withdrawal a year is allowed; this is the default if you do nothing. (2) Extension with contribution — submit Form H within one year of maturity to keep depositing. Extensions run in 5-year blocks and can be repeated any number of times.
Eligibility
Can an NRI open a PPF account?
No. Non-Resident Indians cannot open a new PPF account. However, a resident who opened a PPF account and later became an NRI can continue it till maturity (15 years) but cannot extend it thereafter. On maturity the account must be closed and proceeds can be remitted abroad.
PPF vs ELSS — which is better for tax saving?
Both qualify for Section 80C up to ₹1.5 lakh. PPF gives guaranteed 7.1% tax-free returns, a 15-year lock-in and zero market risk — ideal for conservative investors. ELSS has the shortest lock-in (3 years) among 80C options and potential for higher returns (12–15% historically) but with market risk; LTCG above ₹1.25 lakh is taxed at 12.5%. Choose PPF for guaranteed risk-free growth; ELSS for potentially higher, market-linked returns.
Can I open a PPF account for my child?
Yes. A parent or legal guardian can open a PPF account on behalf of a minor. However, the combined deposit of the guardian's own account and the minor's account cannot exceed ₹1,50,000 in a financial year for 80C purposes.
