PPF Calculator 2026: Public Provident Fund Maturity at 7.1%
By Pratik Bajoria, Chartered Accountant & NISM-certified Research Analyst · Updated 3 October 2026 · Rate as of 1 October 2026
The Public Provident Fund (PPF) is a 15-year, government-backed savings scheme run through post offices and banks. This PPF calculator projects your maturity value from a yearly deposit, the interest rate and the number of years — including extensions beyond 15 years. The current PPF rate is 7.1% a year for 1 October – 31 December 2026, unchanged by the Ministry of Finance in its 30 September 2026 review (see the National Savings Institute rate table).

PPF formula (how the calculator works)
PPF interest compounds once a year. With the full deposit made by 5 April each year:
Balance(year t) = [Balance(t−1) + Deposit] × (1 + r)
Summed over 15 years this equals the annuity-due formula F = P × [((1 + r)^n − 1) ÷ r] × (1 + r). Example: P = ₹1,50,000, r = 0.071, n = 15 gives about ₹40,68,209. Deposits made after 5 April lose a month's interest on that amount, so real balances can be slightly lower.

What if the PPF rate changes?
The rate is reset quarterly. ₹1.5 lakh a year for 15 years at different average rates:
| Average rate | Maturity | Interest earned |
|---|---|---|
| 6.5% | ₹38,63,102 | ₹16,13,102 |
| 7.1% | ₹40,68,209 | ₹18,18,209 |
| 7.6% | ₹42,48,290 | ₹19,98,290 |
| 8% | ₹43,98,642 | ₹21,48,642 |
The PPF rate was 8.0% as recently as October 2018 – June 2019 and has been 7.1% since 1 April 2020; future rates are unknown.
PPF extension: with or without deposits
Within one year of maturity you can submit the extension form (Form 4) to continue with deposits for 5 more years; if you do nothing, the account continues without deposits and keeps earning interest. With deposits, the 20-year balance is about ₹66,58,288; without, about ₹57,32,587. During an extension with deposits you can withdraw up to 60% of the balance at the start of the block; without deposits, one withdrawal of any amount a year.
Where PPF fits in your plan
- Debt anchor for long goals: pair PPF with equity SIPs (SIP calculator, step-up SIP calculator).
- For a daughter's education or marriage, compare with Sukanya Samriddhi (8.2%).
- For retirement, salaried investors already build EPF; see also NPS.
- PPF is not an emergency fund — partial withdrawals start only in year 7. Keep 6 months of expenses liquid (emergency fund guide).
Frequently asked questions
What is the PPF interest rate for October–December 2026?
7.1% a year, compounded annually. The Ministry of Finance kept small savings rates unchanged for Q3 FY 2026-27 (1 October – 31 December 2026) in its Office Memorandum dated 30 September 2026. The rate is reviewed every quarter, so a long-term PPF projection is an estimate, not a guarantee of the rate.
How much will I get if I invest ₹1.5 lakh a year in PPF for 15 years?
At 7.1% for all 15 years, ₹1,50,000 deposited by 5 April every year grows to about ₹40,68,209 — ₹22,50,000 deposited plus about ₹18,18,209 of tax-free interest.
What is the PPF maturity amount after extending for 5 or 10 years?
If you keep depositing ₹1.5 lakh a year at 7.1%, the balance is about ₹66,58,288 after 20 years and ₹1,03,08,015 after 25 years. If you extend without fresh deposits after year 15, the ₹40,68,209 keeps earning interest and reaches about ₹57,32,587 at year 20.
Why should I deposit in PPF before 5 April?
PPF interest for a month is calculated on the lowest balance between the 5th and the last day of that month. A deposit made on or before the 5th earns interest for that month; one made later misses it. Depositing the full yearly amount by 5 April earns interest for all 12 months of the financial year.
Is PPF interest tax-free in 2026-27?
Yes. PPF interest and maturity are exempt from tax. Deposits up to ₹1.5 lakh a year qualify for a deduction under the old tax regime (Section 80C of the 1961 Act, now carried into the Income-tax Act, 2025); the new regime does not give this deduction, but the interest stays tax-free.
When can I withdraw money from PPF?
Partial withdrawal is allowed once a year from the 7th financial year (after 5 complete years), up to 50% of the balance at the end of the 4th preceding year or the immediately preceding year, whichever is lower. Loans are available from the 3rd to the 6th financial year. Premature closure after 5 years is allowed only for specified reasons such as serious illness or higher education, with an interest penalty.
PPF vs SIP: which is better?
They do different jobs. PPF gives a government-backed, tax-free 7.1% (current rate) with a 15-year lock-in; an equity SIP has no fixed return and no lock-in but can compound faster over long periods with volatility. ₹12,500 a month for 15 years is ₹40,68,209 in PPF at 7.1% versus about ₹52,24,053 in a SIP if it earned an assumed 10% a year — an illustration, not a forecast. Many families hold both.
