A projection at today's rate, not financial advice.
This tool projects your PPF maturity at today's rate held constant — it is not financial advice. The PPF rate is reviewed every quarter by the Ministry of Finance, so the real maturity moves if the rate moves. The projection assumes one deposit a year, made by 5 April so it earns interest for the full year.

What does a PPF calculator do?
The Public Provident Fund is a government-backed savings scheme with a 15-year lock-in: you deposit up to ₹1,50,000 a year, the balance earns interest that is reviewed every quarter — 7.1% a year since April 2020 — and the whole maturity amount is tax-free. This calculator works out what that adds up to: the maturity value, the total you deposit, the tax-free interest you earn, and the balance year by year, so you can see exactly how compounding builds the corpus — and what five more years are worth.
01 / FIFTEEN YEARS
A lock-in with a payoff
Fifteen years is a long time to leave money alone — and that is the point. The balance compounds for a decade and a half, and the interest in the later years is earned on a balance several times the yearly deposit. Extending in 5-year blocks adds even more.
02 / THE 5 APRIL RULE
Deposit early, earn the full year
PPF interest is worked out on the minimum balance between the 5th and the last day of each month. A deposit made by 5 April earns interest for the whole year; a deposit made on 10 April misses April's interest on that money — and that gap compounds for 15 years.
03 / TAX-FREE END TO END
EEE status
PPF is one of the few investments that is tax-free at every stage: the deposit is deductible under Section 80C (old regime), the interest each year is exempt, and the maturity amount is fully tax-free. The interest figure on this page is money you keep in full.
How it works
From one deposit to a maturity value
Enter the yearly deposit first — the rate and tenure are
already filled in with the current figures — then read the
maturity, the breakup and the year-by-year table.
01
Enter your yearly deposit
How much you will put in each financial year — from ₹500 to ₹1,50,000, in multiples of ₹50. The maximum deposit gives the maximum maturity.
02
Check the rate and the tenure
The rate is pre-filled at the current 7.1%. Pick 15 years, or 20, 25 or 30 years if you plan to extend in 5-year blocks after maturity.
03
Read the maturity and the breakup
The answer appears as you type — maturity value, total deposited and total interest — with the step-by-step working underneath so you can check every number.
04
Scroll the year-by-year table
Each row shows the opening balance, the deposit, the interest and the closing balance for that year, so you can see compounding build the corpus.
The calculation, explained
How PPF maturity is calculated
One deposit a year, made by 5 April, earns interest for the full year. Each year's interest is (opening balance + deposit) × rate ÷ 100, rounded to the nearest rupee, and added to the balance. Maturity = total deposited + total interest. The closed form is M = P × [((1 + r)^n − 1) ÷ r] × (1 + r), where P is the yearly deposit, r the rate and n the years.
The PPF formula
M = P × [((1 + r)^n − 1) ÷ r] × (1 + r) · Interest each year = (opening balance + deposit) × rate ÷ 100, rounded to the rupee · Maturity = total deposited + total interest
1. First year: deposit earns a full year
1,50,000 × 7.1 ÷ 100 = 10,650Deposit by 5 April and the whole deposit earns interest for the year. Closing balance: 1,60,650.
2. Fifteen years of compounding
22,50,000 deposited · 18,18,208 interestEach year's interest is added to the balance, so the next year's interest is earned on a bigger sum.
3. Maturity after 15 years
22,50,000 + 18,18,208 = 40,68,208Withdraw the full amount tax-free, or extend in 5-year blocks.
Deposit by 5 April to earn a full year's interest
PPF interest is worked out on the minimum balance between the 5th and the last day of each month. A deposit made by 5 April earns interest for the whole year; a deposit made on 10 April misses April's interest on that money. Across 15 years, depositing early every year is worth thousands.

7.1% · 15 YEARS
₹1,50,000 a year for 15 years grows to ₹40,68,208
15 × ₹1,50,000 = ₹22,50,000 deposited; the interest adds ₹18,18,208, so the maturity is ₹40,68,208 — your money grows 1.81 times, all of it tax-free.
₹1,50,000 a year × 15 years @ 7.1% → ₹40,68,208 (interest ₹18,18,208)
7.1% · 15 YEARS
₹1,00,000 a year for 15 years grows to ₹27,12,139
15 × ₹1,00,000 = ₹15,00,000 deposited; the interest adds ₹12,12,139, so the maturity is ₹27,12,139. Two-thirds of the final amount is your own money, one-third is interest.
₹1,00,000 a year × 15 years @ 7.1% → ₹27,12,139 (interest ₹12,12,139)
7.1% · 20 YEARS
One 5-year extension lifts the same ₹1,50,000 a year to ₹66,58,287
20 × ₹1,50,000 = ₹30,00,000 deposited; the interest adds ₹36,58,287. Five extra years nearly double the interest — from ₹18,18,208 to ₹36,58,287 — because the bigger balance compounds.
₹1,50,000 a year × 20 years @ 7.1% → ₹66,58,287 (interest ₹36,58,287)
7.1% · 15 YEARS
₹50,000 a year for 15 years grows to ₹13,56,070
15 × ₹50,000 = ₹7,50,000 deposited; the interest adds ₹6,06,070, so the maturity is ₹13,56,070. Even a modest yearly deposit nearly doubles over the lock-in.
₹50,000 a year × 15 years @ 7.1% → ₹13,56,070 (interest ₹6,06,070)

Common mistakes
Four ways to get PPF wrong
The formula is short, but four readings trip people up.
Each one can cost thousands over fifteen years.
01 / DEPOSITING LATE
Depositing after the 5th
Interest is calculated on the minimum balance between the 5th and the last day of the month. A deposit on 10 April misses April's interest on that money — and that gap compounds for 15 years.
02 / COUNTING 16 DEPOSITS
Assuming 16 deposits in 15 years
Maturity is counted from the end of the financial year you open the account, so you may make a 16th deposit in the opening year. The standard 15-year figure assumes 15 deposits — the FAQ explains the difference.
03 / FREEZING THE RATE
Treating 7.1% as fixed for 15 years
The rate is reviewed every quarter and can change. This page projects at today's rate held constant; the real maturity moves if the rate moves. Try 8% or 6% in the rate box to see the difference.
04 / OVER THE CAP
Depositing more than ₹1,50,000 a year
Anything above the cap earns no interest and gets no Section 80C deduction. Put the extra into another instrument instead of letting it sit idle in the PPF account.
Your questions, answered
PPF calculator FAQs
What is PPF?
The Public Provident Fund is a government-backed, long-term savings scheme, introduced in 1968 and now governed by the Public Provident Fund Scheme, 2019. You deposit up to ₹1,50,000 a year, the balance earns interest set by the government, and after a 15-year lock-in you withdraw the whole amount tax-free. You can open an account at a post office or an authorised bank.
What is the current PPF interest rate?
7.1% a year, compounded annually. The rate is set every quarter by the Ministry of Finance (Department of Economic Affairs) and has been unchanged since April 2020. The latest notification — Office Memorandum F.No.1/4/2019-NS, dated 30 September 2026 — keeps 7.1% for 1 October to 31 December 2026. The next review is due around 31 December 2026.
How is the PPF maturity amount calculated?
One deposit a year, made by 5 April, earns interest for the full year. Each year's interest is (opening balance + deposit) × rate ÷ 100, rounded to the nearest rupee, and added to the balance. Over 15 years at 7.1%, ₹1,50,000 a year becomes ₹40,68,208: ₹22,50,000 deposited plus ₹18,18,208 of interest. The closed form is M = P × [((1 + r)^n − 1) ÷ r] × (1 + r).
What are the minimum and maximum PPF deposits?
At least ₹500 a year to keep the account active, and at most ₹1,50,000 a year, in multiples of ₹50. The ₹1,50,000 cap covers your own account plus any account you hold as a guardian for a minor. Anything deposited above the cap earns no interest and gets no Section 80C deduction.
Can I extend my PPF account after 15 years?
Yes — in blocks of 5 years each, as many times as you like, with or without making further deposits. To keep depositing after maturity, apply in Form 4 within one year of maturity. If you extend without deposits, the balance keeps earning interest and you may withdraw any amount once a year.
When can I withdraw from my PPF account?
Partial withdrawals open from the 7th financial year: once a year, up to 50% of the lower of the balance at the end of the 4th year before the withdrawal year or the balance at the end of the preceding year — and the amount is tax-free. After 15 years you may withdraw the full maturity amount. Premature closure is allowed only in specific cases, such as serious illness or a child's higher education, after 5 years.
Can I take a loan against my PPF balance?
Yes, between the 3rd and 6th financial years: up to 25% of the balance at the end of the 2nd year immediately preceding the year you apply, repayable within 36 months, at 1% above the prevailing PPF rate. Only one loan a year, and no fresh loan until the earlier one is fully repaid. Once partial withdrawals open in year 7, the loan facility ends.
Is PPF tax-free?
Yes — PPF has EEE status: Exempt-Exempt-Exempt. The deposit is deductible under Section 80C (up to ₹1,50,000 a year, under the old tax regime only), the interest earned each year is exempt, and the maturity amount is fully tax-free under Section 10(11) in both tax regimes.
Does this calculator send my numbers anywhere?
No. Every calculation runs entirely on this page — nothing is sent to a server, nothing is stored, and reloading the page clears your recent checks.
About the method
This page uses the standard PPF formula: one deposit a year,
made by 5 April so it earns interest for the full year;
each year's interest is (opening balance + deposit) × rate
÷ 100, rounded to the nearest rupee, and added to the
balance; maturity = total deposited + total interest. The
closed form is M = P × [((1 + r)^n − 1) ÷ r] × (1 + r).
The model assumes 15 yearly deposits for a 15-year tenure —
the same convention as the standard PPF calculators. Because
maturity is counted from the end of the financial year you
open the account, you may be able to make a 16th deposit in
the opening year; at the maximum deposit that would lift the
15-year maturity from ₹40,68,208 to ₹45,17,701.
Rate checked 11 November 2026: 7.1% a year for 1 October to
31 December 2026, per the Ministry of Finance (Department
of Economic Affairs) Office Memorandum F.No.1/4/2019-NS,
dated 30 September 2026, keeping small savings rates
unchanged for the third quarter of FY 2026-27. The deposit
limits, tenure, loan and withdrawal rules are from the
Public Provident Fund Scheme, 2019 (G.S.R. 915(E), 12
December 2019). Cross-checked against the ranking PPF
calculators: ₹1,50,000 a year for 15 years at 7.1% gives
₹40,68,208 on
calcsolver.in,
and ₹1,00,000 a year for 15 years gives ₹27,12,139 on
onlycalculators.com.
Spreading the same yearly deposit across monthly
instalments earns less, because later instalments miss
months of interest — this calculator models the yearly lump
sum made by 5 April, and says so on the page.
