Advanced options
- PPF interest is computed month by month on the lowest balance between the 5th and the end of each month, and credited once a year — deposit by the 5th so the money counts from that month.
- Worked example from the guide: $150,000 a year at 7.1% for 15 years → maturity $4,068,209.22 on $2,250,000 invested — $1,818,209.22 of interest.
- PPF matures after 15 financial years and can be extended in 5-year blocks, with or without fresh deposits; the rate (currently 7.1% p.a.) is set by the government and revised periodically.

Withdrawals and loans
From the 7th year you can withdraw part of your PPF balance, and in years 3 to 6 you can borrow against it — check the exact scheme limits for your account.
One withdrawal is allowed per financial year once five years have passed from the end of the year in which the account was opened. Any outstanding loan must be repaid before you withdraw.
A loan is available from the 3rd to the 6th financial year, up to 25% of the balance at the end of the 2nd preceding year — one loan a year, and a fresh loan only once the earlier one is repaid in full.

PPF in plain words: the 15-year account, the cap, and the extensions
PPF stands for Public Provident Fund, a long-term savings scheme with a government-set interest rate and fully tax-free returns. An account runs for 15 financial years. You are not forced to withdraw at 15: the account can be extended in blocks of 5 years, with fresh deposits or without them, and the balance keeps earning interest either way.
There is a yearly cap and a yearly floor. The maximum deposit is $150,000 per financial year, across all your PPF accounts combined, and the minimum to keep an account active is $500 a year. Deposits above the cap earn no interest and do not qualify for the tax deduction, so the calculator blocks any amount over the cap. Amounts on this page are shown in $ like the rest of the page; the scheme itself is rupee-denominated.
The interest rate is set by the government and revised periodically, usually every quarter. The rate history on this page shows 7.1% a year applying since 1 April 2020, and the calculator rate field is editable so you can model any rate. Treat long projections as estimates: if the rate changes, re-run the projection at the new rate.
| Yearly deposit | Rate | Tenure | Maturity value | Total interest |
|---|---|---|---|---|
| $150,000 | 7.1% | 15 years | $4,068,209.22 | $1,818,209.22 |
| $150,000 | 7.1% | 20 years (one extension) | $6,658,288.17 | $3,658,288.17 |
Both rows use the figures already worked on this page, at the stated 7.1% rate held constant. The extension row is the reward for patience: five more years of deposits and compounding add $2,590,078.95 to the maturity value. One timing habit is worth more than any rate chase: deposit by the 5th of the month, because interest for a month is computed on the lowest balance between the 5th and the end of that month, and a late deposit loses a month of growth.
⚙️How PPF maturity is calculated
PPF interest is worked out month by month: for every month, interest is computed on the lowest balance between the close of the 5th and the end of the month (PPF Scheme, 2019, para 7), and the twelve monthly amounts are credited together on 31 March. With a fixed yearly deposit P made on 1 April, rate i and n years, that monthly rule adds up to the familiar closed form:
FV = P × (((1+i)ⁿ − 1) ÷ i) × (1+i) — yearly deposit made on 1 April · interest = FV − invested
Worked example: $150,000 per year at 7.1% for 15 years → maturity value $4,068,209.22, total invested $2,250,000, total interest $1,818,209.22. The same total saved monthly — $12,500 a month paid in by the 5th — matures to $3,944,599.22, because each instalment starts earning from its deposit month; pay after the 5th instead and it falls to $3,922,124.68. The calculator assumes the rate stays constant — in reality the government revises it, usually every quarter, so treat long projections as estimates.
PPF interest is credited once a year (on 31 March) but computed monthly on the lowest balance between the 5th and the end of each month. That is why deposits made before the 5th of a month earn interest for that month, and late deposits lose a month of growth. This calculator runs exactly that monthly rule — choose a monthly deposit, or a deposit day after the 5th, and you can see the interest the timing costs.
The rate itself is set by the government and revised periodically (currently 7.1% p.a. — the field above is editable so you can model any rate).

Rates as notified by the Ministry of Finance (Department of Economic Affairs) and published in the National Savings Institute rate history — checked October 2026. The 7.1% rate has applied since 1 April 2020 and was confirmed unchanged for the October–December 2026 quarter (DEA office memorandum, 30 September 2026).
PPF matures after 15 financial years. You are not forced to withdraw: the account can be extended in blocks of 5 years, with or without fresh deposits. Extending with deposits keeps the $150,000.0 yearly cap and the 80C deduction; extending without deposits still earns interest on the balance, and you may withdraw partially once per year.
The tenure dropdown above models 15–50 years, so you can compare “withdraw at 15” against one, two or three extensions. Example: $150,000/year at 7.1% grows from $4,068,209.22 at 15 years to $6,658,288.17 at 20 years — compounding rewards patience.
PPF enjoys EEE (exempt-exempt-exempt) status: deposits qualify for deduction under Section 80C (up to ₹1,50,000), the interest earned is tax-free, and the maturity amount is tax-free. Few instruments combine a sovereign guarantee with fully tax-free returns — which is why PPF remains the default long-term debt anchor for many Indian savers, even at modest rates.
Note: 80C deductions apply under the old tax regime; confirm your regime’s rules before counting the benefit. This is general information, not tax advice.
The 5th-to-5th rule: why deposit timing matters
PPF interest is not calculated on the month-end balance. It is calculated on the lowest balance between the close of the 5th day of the month and the end of the month, which means a deposit made on the 4th earns interest for that month, while the same deposit made on the 6th does not. The rule is small, it is easy to miss, and over 15 years of monthly deposits it is worth real money.
The habit it rewards is simple: deposit by the 5th. A depositor who puts money in on the 3rd of every month earns a full extra month of interest on every deposit compared with a depositor who pays on the 10th, and the difference compounds across 180 deposits. The rule does not change the rate or the cap; it changes which deposits the rate applies to, and that is enough to separate a good PPF habit from a careless one.
Extension blocks: 15 years, then 5 at a time
A PPF account matures after 15 years, but maturity is not the end of the story. The account can be extended in blocks of 5 years, indefinitely, with or without fresh contributions, and the choice matters: extending with contributions keeps the tax benefit on new deposits and keeps the account growing, while extending without contributions lets the existing balance keep earning interest without new money going in.
PPF in brief. Rates are revised quarterly; 7.1% applied for October to December 2026. The annual deposit cap is ₹1.5 lakh.
| Feature | Rule |
|---|---|
| Term | 15 years, then 5-year extensions |
| Annual deposit cap | ₹1.5 lakh |
| Interest basis | Lowest balance, 5th to month-end |
| Rate, Oct-Dec 2026 | 7.1% per annum |
Partial withdrawals are available from the 7th year, and loans against the balance from the 3rd year, but both reduce the balance that earns interest, and both are governed by the lowest-balance rule in the months they are taken. The extension decision, the withdrawal decision, and the deposit-timing habit are the three levers a PPF holder actually controls; the rate itself is set by the government and revised quarterly.
Frequently asked questions
How is PPF maturity calculated?
Interest is computed for each month on the lowest balance between the close of the 5th and the end of the month, then credited on 31 March — the calculator runs this monthly rule directly. For a yearly deposit made at the start of the year it adds up to FV = P × (((1+i)ⁿ − 1) ÷ i) × (1+i): $150,000/year at 7.1% for 15 years matures to $4,068,209.22 ($2,250,000 invested + $1,818,209.22 interest).
What is the maximum I can deposit in PPF?
$150,000 per financial year — across all your PPF accounts combined. Deposits above the cap earn no interest and are not eligible for 80C deduction, so the calculator above blocks any amount over $150,000.0 with an error message. The minimum to keep an account active is $500 per year.
Can I change the interest rate in the calculator?
Yes — the rate field is fully editable. It defaults to 7.1% p.a., but the government revises the PPF rate periodically (usually every quarter), so long projections should be re-run with the current rate. Editing the rate instantly re-computes maturity, interest and the full year-wise table.
What happens to my PPF after 15 years?
You can withdraw the full maturity amount tax-free, or extend in 5-year blocks — with fresh deposits (keeping the $150,000.0 cap and 80C benefit) or without (the balance keeps earning interest, with one partial withdrawal allowed per year). The tenure dropdown models up to 50 years so you can compare extension scenarios.
Is PPF interest taxable?
No. PPF has EEE status: deposits get 80C deduction, interest is tax-free, and maturity proceeds are tax-free. This applies under the old tax regime’s 80C framework — confirm the rules for your chosen regime. General information only, not tax advice.
PPF vs FD vs SIP — which grows more?
It depends on rate, tax and risk. PPF offers sovereign-guaranteed, tax-free ~7.1%; bank FDs pay similar pre-tax rates but interest is taxable; equity SIPs have historically returned more over 15+ years but with market risk and LTCG tax. Compare directly with the FD Calculator and SIP Calculator — PPF usually wins for the safe, tax-free debt portion of a portfolio.
What is a PPF account, and how long does it last?
PPF stands for Public Provident Fund, a long-term savings scheme with a government-set interest rate and fully tax-free returns. An account runs for 15 financial years, and at maturity you can withdraw the full amount tax-free or extend the account in 5-year blocks, with fresh deposits or without them. Extending without deposits still earns interest on the balance, with one partial withdrawal allowed per year.
What is the PPF deposit limit?
The maximum deposit is $150,000 per financial year, across all your PPF accounts combined, and the minimum to keep an account active is $500 a year. Deposits above the cap earn no interest and are not eligible for the tax deduction, so the calculator on this page blocks any amount over $150,000. Amounts here are shown in $ like the rest of the page; the scheme itself is rupee-denominated.
Why should I deposit into PPF before the 5th of the month?
Because interest is calculated on the lowest balance between the close of the 5th and the end of the month. A deposit made by the 5th earns interest that month; one made after does not, and the difference compounds over 15 years.
What happens when my PPF matures after 15 years?
You can extend in blocks of 5 years, with or without fresh contributions. Extending with contributions keeps the tax benefit on new deposits; extending without lets the existing balance keep earning interest.
What is the PPF deposit limit?
₹1.5 lakh per financial year. The interest rate is set by the government and revised quarterly; it was 7.1% per annum for October to December 2026.
