What does the PPF Calculator do?
PPF Calculator works out the maturity from the Annual Investment, PPF Rate, and Tenure, following standard Regional conventions — the page defaults produce a maturity of ₹40,68,209.22.
- Inputs: Annual Investment, PPF Rate, and Tenure.
- Output: the maturity, plus the intermediate steps behind it.
- Method: the standard Regional formula, evaluated entirely in your browser.
Quick answer
With the default inputs (annual investment of 150,000, ppf rate of 7.1, tenure of 15), ppf calculator returns a maturity of ₹40,68,209.22. Assumptions and limits are summarized below.
How does the PPF Calculator work?
PPF Calculator computes the maturity directly from your inputs — the Annual Investment, PPF Rate, and Tenure feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
What This Calculator Really Does
The Public Provident Fund is India's long-term savings scheme: a 15-year lock-in, contributions from ₹500 up to ₹1.5 lakh per year, and a rate the government notifies quarterly. This calculator projects the maturity value by compounding each yearly contribution from the year it is made to the end of year 15.
The projection is exact for whatever rate you enter — but the rate itself is not fixed for the whole tenure. It resets quarterly with government notification, so the honest reading is "at today's rate, held constant," which is why the assumptions section matters.

Quick answer: ₹1,50,000 deposited every year for 15 years at 7.1% matures to roughly ₹40.7 lakh — ₹22.5 lakh contributed, about ₹18.2 lakh in interest.
The Formula, Explained Plainly
FV = A × [((1 + r)ⁿ − 1) ÷ r] × (1 + r)
- A — the annual deposit (₹500 to ₹1,50,000 per financial year).
- r — the annual rate as a decimal (7.1% → 0.071).
- n — the number of years of deposits (up to 15).
This is the same annuity-due structure as a SIP at yearly frequency: each deposit earns from the start of its year — the convention that matches deposits made in the first days of the financial year. Deposits made late in the year earn correspondingly less.
How to Use It — In Order
- Enter the yearly deposit — up to the ₹1.5 lakh annual ceiling.
- Enter the current rate — the quarterly-notified figure; the tool holds it constant and says so.
- Set the tenure — 15 years for the base account; extensions in 5-year blocks change the projection horizon.
- Read invested vs interest — the maturity split the tool shows.
- Compare deposit timing — the same annual sum deposited in April earns more than one deposited in March.
- Model an extension — with or without fresh contributions, the fifth-year block compounds on the full balance.
Worked Example, Verified by Hand
₹1,50,000 every year, 7.1%, 15 years:
- (1.071)¹⁵ = 2.79776 (compounded year by year: 1.071² = 1.14704, ¹⁴ = 1.73107 × 1.14704 × 1.071).
- (2.79776 − 1) ÷ 0.071 = 25.3200.
- × 1.071 = 27.1177 (annuity-due factor).
- × 1,50,000 = ≈ ₹40,67,655 maturity value.
- Invested: 1,50,000 × 15 = ₹22,50,000 → interest ≈ ₹18,17,655.
Extending five more years with no new deposits compounds ₹40.68 lakh at 7.1% → about ₹57.3 lakh by year 20 — the extension's entire value is compounding on what exists.
Common Mistakes to Avoid
- Assuming today's rate holds for 15 years — it is notified quarterly; projections are conditional on the rate you enter.
- Missing the deposit-timing effect — April deposits earn a full year's interest; March deposits almost none for that year.
- Exceeding the ₹1.5 lakh annual ceiling — excess deposits earn nothing; split surplus into other instruments.
- Comparing PPF to equity returns on nominal figures — PPF is sovereign-backed and tax-free at maturity; risk classes differ.
- Ignoring partial-withdrawal rules — years 7 to 15 allow limited withdrawals; modeling the full balance to maturity overstates liquidity.
Limitations
- Constant-rate projection — the government resets the rate quarterly; realized maturity varies with the path.
- Annual-frequency model — monthly deposit staggering within the year is approximated, not simulated.
- Not tax advice — the EEE treatment summary is general; confirm current rules with a professional.
Expected Accuracy
The annuity-due compounding is exact at full floating-point precision and matches a hand calculation to the rupee for the same rate and schedule. Rate-path uncertainty is an assumption issue, not arithmetic one.
Privacy — Your Data Never Leaves This Device
Deposit amounts stay in your browser: no account, no upload, no tracking — the tool works offline too.

Bottom Line
Same annuity-due math as a SIP, at yearly frequency and a notified rate: deposit early in the year, respect the ceiling, and treat the rate as today's snapshot — not a 15-year promise.

Frequently Asked Questions
How is PPF maturity value calculated?
Each year's deposit compounds at the notified rate until the end of year 15: FV = A × [((1 + r)ⁿ − 1) ÷ r] × (1 + r) for deposits A made at the start of each year.
What will ₹1.5 lakh per year in PPF grow to?
At 7.1% held constant for 15 years: about ₹40.68 lakh — ₹22.5 lakh deposited and roughly ₹18.18 lakh interest.
What is the current PPF interest rate?
The Ministry of Finance notifies it quarterly. Enter the prevailing notified rate in the calculator; do not assume it persists for the full 15 years.
When should I deposit to earn the most interest?
Early in the financial year — ideally April. Deposits made before the fifth day of the month earn interest for that month under the scheme's interest rules.
Can I extend PPF after 15 years?
Yes, in 5-year blocks, with or without fresh contributions. The calculator's tenure field lets you model the extended horizon.
Is PPF interest taxable?
Currently exempt — deposits qualify for Section 80C deduction and maturity proceeds are tax-free under the prevailing EEE treatment. Confirm current rules at withdrawal time.
Is this calculator free and private?
Yes — it runs entirely in your browser, stores nothing, and works offline after the first visit.
What does the PPF Calculator calculate?
PPF Calculator turns the values you enter into a verified output — the formula, every intermediate step, and the assumptions sit beside the result instead of hidden behind it. Because the page doubles as documentation: PPF Calculator puts the formula, a worked example, and the assumptions right beside the calculator.
How is the maturity calculated?
The first steps are ppf compounds annually with tax-free interest, then annual investment = ₹1,50,000. PPF Calculator substitutes the Annual Investment, PPF Rate, and Tenure into the formula, evaluates it in the order shown in the steps panel, and reports the maturity rounded for readability.
What do I need to use the PPF Calculator?
The Annual Investment, PPF Rate, and Tenure it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the maturity instantly.
What does the result from the PPF Calculator mean?
The main number the ppf calculator returns is the maturity for your exact inputs, and the supporting figures and step list give it context. Treat the maturity as a planning figure rather than a binding quote, and confirm important decisions with the relevant professional.
When is the PPF Calculator most useful?
Typical uses for PPF Calculator include planning and budgeting, comparing scenarios side by side, and double-checking the maturity — anywhere the figure needs to be defensible rather than guessed. Run PPF Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the output is, which a single run never shows.
