How do I calculate the maturity value of a PPF account?

Enter your yearly deposit, the interest rate (7.1% p.a. by default, the current government rate) and the tenure into AnyTool PPF Calculator, and it instantly shows the maturity value, the total you deposited and the total tax-free interest earned. A Public Provident Fund compounds annually, so for a constant yearly deposit it uses M = A × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), with each deposit placed at the start of the year. You can keep the 15-year lock-in or extend in 5-year blocks to 20 or 25 years, with or without fresh deposits. A pure-SVG growth chart and a year-by-year table show your deposits versus interest, and everything is calculated in your browser, so nothing is uploaded.

  • M = A × [((1 + i)ⁿ − 1) ÷ i] × (1 + i); interest compounded annually
  • Editable rate (7.1% default), 15-year lock-in with 5-year extensions to 20 / 25 years
  • Maturity value, total invested and tax-free interest, with a growth chart
  • Tax-free at every stage (EEE): 80C deduction, interest and maturity exempt

What is

PPF (Public Provident Fund)

A Public Provident Fund (PPF) is a long-term, government-backed savings scheme in India with a 15-year lock-in. You may deposit between ₹500 and ₹1,50,000 per financial year; interest is compounded annually (currently 7.1% p.a., a rate the government revises every quarter) and credited on 31 March, calculated on the lowest balance between the 5th and the last day of each month. PPF enjoys Exempt-Exempt-Exempt (EEE) tax status — deposits qualify under Section 80C, and the interest and maturity are tax-free. After maturity the account can be extended in blocks of five years, with or without further contributions.

Frequently Asked Questions

The PPF rate is 7.1% per year, compounded annually and credited on 31 March, calculated on the lowest balance between the 5th and the end of each month.

The Public Provident Fund rate is 7.1% per annum as of the recent quarters, set by the Ministry of Finance, which reviews it every quarter, so it can change over a 15-year tenure. Interest compounds annually and is credited at the end of the financial year, but it is computed each month on the lowest balance between the 5th and the last day of that month — which is why depositing before the 5th earns the most. AnyTool PPF Calculator lets you edit the rate for whichever quarter you are in and uses the standard deposit-at-start-of-year approximation, the same one mainstream calculators use, so its figures match theirs.

You must deposit at least ₹500 and at most ₹1,50,000 in a PPF account per financial year to keep it active and earning interest.

A PPF account requires a minimum deposit of ₹500 in a financial year to stay active — miss it and the account becomes dormant until you revive it with a small penalty. The maximum that earns interest is ₹1,50,000 per financial year; anything above that is treated as irregular and earns nothing. The same ₹1,50,000 cap qualifies for a Section 80C tax deduction. AnyTool warns you if your yearly deposit falls outside the ₹500–₹1,50,000 band but still computes the figure so you can explore what-if scenarios.

Yes — after the 15-year maturity you can extend the account in blocks of five years, any number of times, with or without making fresh deposits.

When a PPF matures at the end of 15 years you have three choices: withdraw the full amount, leave it to keep earning interest without new deposits, or extend it in a fresh five-year block and continue depositing up to ₹1,50,000 a year with the same tax benefits. Extension blocks can be repeated indefinitely, but if you want to keep depositing you must opt in within one year of maturity. AnyTool lets you model 15, 20 or 25 years and toggle whether you keep depositing during the extension, so you can see exactly how much an extra block adds.

No — PPF is tax-free at every stage (EEE), so deposits, interest and maturity are all exempt; and nothing is uploaded, every calculation runs in your browser.

PPF has Exempt-Exempt-Exempt (EEE) tax status: the yearly deposit is deductible up to ₹1,50,000 under Section 80C, the interest credited each year is tax-free, and the maturity proceeds are exempt when withdrawn — one of the few investments taxed at none of the three stages. This calculator assumes a constant rate and a deposit at the start of each year, so it is a close planning estimate rather than your exact passbook figure. AnyTool PPF Calculator runs entirely in your browser, so your deposit and rate are never sent to a server and the page works offline.

Detailed Explanation

Methodology

How the PPF Calculator Works

AnyTool PPF Calculator projects a Public Provident Fund account in the browser. PPF interest is compounded annually, so for a constant yearly deposit the maturity is the future value of an annuity-due, M = A × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), where A is the yearly deposit, i is the annual rate as a decimal and n is the number of years, with each deposit placed at the start of the year so it earns a full year of interest. Rather than only evaluate the closed form, the calculator builds the schedule one year at a time — adding the deposit to the opening balance, crediting a year of interest and carrying the closing balance forward — so a 5-year extension block, with or without fresh deposits, still computes correctly. The default rate is 7.1% (the current government rate) but is fully editable, and the 0% case degrades cleanly to simply the money deposited. All arithmetic is pure client-side JavaScript in a reusable PPF engine.

  • M = A × [((1 + i)ⁿ − 1) ÷ i] × (1 + i); interest compounded annually
  • Deposit placed at the start of each year (annuity-due / deposit-at-start)
  • Schedule built year by year so extensions with or without deposits work
  • Editable rate (7.1% default); 0% rate returns just the money deposited
  • All math is client-side JavaScript in a reusable engine — no server round-trip
Use Cases

PPF Rules: Limits, Lock-in, Extensions and EEE Tax

A PPF account requires a deposit of ₹500 to ₹1,50,000 per financial year — below ₹500 the account goes dormant, above ₹1,50,000 the excess earns nothing — and the same ₹1,50,000 is deductible under Section 80C. The lock-in is 15 years from the end of the financial year in which the account was opened. At maturity you can withdraw, hold without new deposits, or extend in blocks of five years (to 20, 25 years and beyond), continuing to deposit up to ₹1,50,000 a year if you opt in within a year of maturity. PPF carries the rare Exempt-Exempt-Exempt (EEE) status: deposits, the annual interest and the maturity proceeds are all tax-free. AnyTool models 15, 20 or 25 years, toggles whether you keep depositing during an extension, and warns when a deposit falls outside the ₹500–₹1,50,000 band while still computing the figure.

  • Yearly deposit limit: ₹500 minimum to ₹1,50,000 maximum, deductible under 80C
  • 15-year lock-in, then extendable in 5-year blocks any number of times
  • Extension can continue deposits (opt in within a year) or just compound
  • EEE tax status: deposit, interest and maturity are all tax-free
  • Out-of-range deposits are flagged but still computed for what-if scenarios
Limitations

A Constant-Rate Estimate, Not the Exact Passbook Figure

The government sets the PPF rate and revises it every quarter, so over a 15-plus-year tenure the rate will almost certainly change; this calculator assumes the single rate you enter stays constant and that you deposit the same amount at the start of each year. The official rule credits interest on the lowest balance between the 5th and the last day of each month, so depositing before the 5th earns the most and a mid-month or month-end deposit earns slightly less than a start-of-year model shows. Like every mainstream PPF calculator, AnyTool uses the deposit-at-start approximation, which matches their published maturity figures, so treat the result as a close planning estimate rather than the exact passbook number.

  • Government revises the PPF rate quarterly — the constant-rate input is a simplification
  • Official interest uses the lowest balance between the 5th and month-end
  • Depositing before the 5th of the month maximises interest
  • Deposit-at-start approximation matches mainstream calculators’ published figures
  • A close planning estimate, not your exact passbook figure
Privacy & Security

Privacy and Offline Use

Because all computation runs in the browser, your yearly deposit, the rate and the tenure are never sent to a server, there is no account or tracking, and the page works offline after first load. The currency selector (₹ default, then $, € and £) only changes how numbers are displayed; the engine itself is currency-agnostic and works in plain numbers, even though PPF is an India-only scheme. The PPF Calculator shares the same privacy-first, client-side approach as the rest of the calculator category, so its behaviour is consistent across the SIP, compound-interest and FD/RD tools.
