The projection keeps one rate for every year. Actual PPF rates may change each quarter. The account office's statement, exact transaction dates and official rules control the final balance.
What Is a PPF Calculator?
A PPF calculator estimates how contributions and annual interest may build your Public Provident Fund balance. Enter a contribution, expected interest rate, payment timing and term. The tool separates the amount you deposit from the tax-free interest and shows a financial-year projection.
PPF is a long-term government small-savings scheme for resident individuals. The official annual deposit range is ₹500 to ₹1,50,000, in multiples of ₹50. A deposit may be made as a lump sum or through instalments. The ₹1.5 lakh ceiling includes eligible deposits in your own account and accounts opened by you for minors.
This calculator also models five-year extensions, an annual contribution increase capped at the statutory limit, the timing rule around the fifth day of each month, inflation and a simplified old-regime tax-benefit estimate.
How to Use This PPF Calculator
- Select annual lump sum or monthly instalments.
- Enter the yearly lump sum or monthly amount. Keep the total within ₹1.5 lakh for each financial year.
- Use 7.1% for the July–September 2026 quarter, or enter another planning rate.
- Select 15 years for the original term. Choose 20, 25 or 30 years to model five-year extensions with deposits.
- Select whether deposits reach the account on or before the fifth day or after it.
- Add an annual step-up if you want contributions to grow with income. The tool stops increases at ₹1.5 lakh a year.
- Include the potential old-regime deduction only if it fits your tax situation. Select a marginal rate.
- Enter expected inflation and select Calculate PPF.
For the standard maximum-contribution illustration, choose annual, ₹1,50,000, 7.1%, 15 years, on or before the fifth, and 0% step-up.
How PPF Interest Is Calculated
PPF interest is eligible for each calendar month on the lowest account balance between the close of the fifth day and the end of that month. Interest is credited at the end of the financial year. A deposit credited by the fifth normally earns interest for that month. A deposit after the fifth starts affecting the eligible balance from the following month, assuming there is no withdrawal.
Monthly interest = eligible monthly balance × annual rate ÷ 12
Year-end balance = opening balance + deposits + sum of monthly interest
The calculator follows this monthly-balance method and adds accumulated interest once at year end. It does not compound interest every month. For annual deposits, the payment is placed in April. For monthly mode, one equal payment is placed in each month.
Read the official Public Provident Fund Scheme, 2019 for the controlling deposit, interest, withdrawal and extension provisions.
Worked PPF Example
Assume you deposit ₹1,50,000 at the start of every financial year for 15 years. The expected rate stays at 7.1% and each payment reaches the account on or before April 5.
- Total contribution: ₹22,50,000
- Estimated tax-free interest: about ₹18,18,209
- Estimated maturity value: about ₹40,68,209
- Money multiple on contributions: about 1.81 times
The annual deposit earns a full year's interest in this illustration. If the same amount arrives after April 5, it misses April interest. Monthly instalments also produce a lower maturity than an equal annual contribution made at the financial year's start because later instalments earn for fewer months.
Latest PPF Interest Rate for 2026
The PPF rate is 7.1% per year for July 1 to September 30, 2026. The Ministry of Finance kept small-savings rates unchanged from the preceding quarter. The government reviews these rates quarterly, while PPF interest is credited annually.
The official Q2 FY 2026–27 small-savings notification confirms the unchanged rates. Do not treat 7.1% as guaranteed for every future year. A 15-year estimate needs an assumed rate, while actual credits use the rates notified from time to time.
PPF Deposit Limits and Account Term
The minimum annual deposit is ₹500 and the maximum is ₹1,50,000. Deposits must follow the scheme's multiples-of-₹50 rule. If the required minimum is not deposited for a year, the account becomes discontinued. It may be revived during the maturity period by paying the prescribed default fee and minimum arrears, subject to current rules.
A PPF account matures after 15 complete financial years from the end of the financial year in which it was opened. This calendar convention means the elapsed time from the opening date can exceed 15 years. The calculator uses 15 annual contribution-and-interest cycles for a clean projection and does not model an opening stub period.
The National Savings Institute PPF summary lists the current minimum, maximum, loan, withdrawal and extension features.
PPF Extension After 15 Years
At maturity, you may close the account, retain it without further deposits, or extend it with deposits in five-year blocks under the scheme conditions. An extension with deposits requires the prescribed option within one year of maturity. If you retain the matured account without deposits for more than a year, the rules do not let you switch back to extension with deposits.
This calculator's 20, 25 and 30-year options assume valid extensions with continued deposits. It applies the entered rate and contribution plan throughout. A real extension needs the applicable form, deadline and account-office confirmation.
Withdrawals during an extension with deposits are subject to a block-level limit. The calculator excludes withdrawals because their dates and amounts materially change future interest.
PPF Tax Benefits and EEE Treatment
PPF is commonly described as exempt-exempt-exempt. Eligible contributions qualify within the combined deduction limit commonly referenced under Section 80C when you use the old tax regime and meet its conditions. Interest credited to the account and eligible maturity proceeds are tax-exempt under the applicable provisions.
The tax-saving output multiplies each modelled contribution by your selected marginal rate. It assumes you have enough taxable income and unused deduction headroom. It excludes cess, surcharge, rebates, special-rate income and the effect of other eligible investments. If EPF, life-insurance premiums, home-loan principal or other items already use the limit, your extra saving from PPF may be lower or zero.
The new tax regime generally does not provide the same contribution deduction. Interest and eligible maturity treatment remain separate questions. Review current filing guidance and the official Income Tax Department deductions guide before claiming a benefit.
Annual Deposit Versus Monthly PPF Deposits
| Factor | Annual lump sum | Monthly instalments |
|---|---|---|
| Cash-flow need | Full amount available early | Spread across the year |
| Interest opportunity | Highest when deposited by April 5 | Later payments earn for fewer months |
| Payment discipline | One planned transaction | Regular standing instruction |
| Annual ceiling | Maximum ₹1.5 lakh | Combined maximum ₹1.5 lakh |
| Best fit | Bonus or ready lump sum | Monthly salary-based saving |
Depositing earlier improves the modelled return, but do not borrow at a high rate or drain emergency cash merely to deposit on April 5. Consistent contributions and adequate liquidity matter more than a small timing gain.
PPF Versus FD, RD and SIP
| Feature | PPF | FD or RD | Mutual-fund SIP |
|---|---|---|---|
| Return | Government-notified, reviewed quarterly | Contracted deposit rate | Market-linked |
| Standard horizon | 15 complete financial years | Chosen deposit tenure | Investor-selected |
| Tax on interest or gains | Eligible PPF interest is exempt | Interest generally taxable | Capital-gains rules apply |
| Liquidity | Restricted loans and withdrawals | Premature closure may be available | Redemption generally available, market value varies |
| Risk profile | Government small-savings scheme | Institution and coverage matter | Market risk |
PPF suits long-term debt allocation and tax-efficient compounding. It is not a complete retirement plan by itself because the annual contribution ceiling restricts scale and long-term goals often need growth assets, liquidity and insurance outside PPF.
Loans, Withdrawals and Premature Closure
The scheme provides a loan window in the early years and partial withdrawals later, subject to balance-based limits and account status. Premature closure is allowed only for specified grounds and after the required period. The scheme applies a one-percentage-point reduction to rates credited from opening or extension for an eligible premature closure.
This calculator assumes no loan, withdrawal, discontinuation or premature closure. Use the year-wise balance only as a planning reference. Ask the account office to calculate eligibility and final proceeds for an actual transaction.
Inflation and Real PPF Value
Maturity is a nominal rupee amount. Inflation reduces its purchasing power. The calculator divides each projected closing balance by (1 + inflation)year to show its value in today's money.
At 6% average inflation, the ₹40.68 lakh example after 15 years has purchasing power of roughly ₹16.97 lakh in today's rupees. This is not an account deduction. It helps you judge whether the maturity amount meets your future goal.
Limitations of This PPF Calculator
The tool assumes one interest rate for the full projection. Actual rates change through government notifications. It simplifies the opening year, uses equal monthly instalments in monthly mode and does not model transaction processing delays, rate changes within a year, exact rounding or irregular deposits.
The annual step-up is a savings plan, not a special PPF feature. Contributions stop increasing once the ₹1.5 lakh annual ceiling is reached. The tax-saving figure is illustrative and excludes your income composition, chosen regime, other deductions, cess, surcharge and law changes.
The calculator does not cover loans, partial withdrawals, discontinued accounts, excess deposits, minor-account aggregation, residency changes, premature closure, death claims or extension withdrawals. Use official records for any transaction.

Frequently Asked Questions
What is the PPF interest rate in July 2026?
The PPF rate is 7.1% per year for July 1 to September 30, 2026. The Ministry of Finance kept small-savings rates unchanged for the quarter.
What is the minimum and maximum PPF deposit?
The official annual minimum is ₹500 and the maximum is ₹1,50,000. The maximum includes eligible deposits in your own account and minor accounts covered by the scheme's aggregation rule.
Why should a PPF deposit be made by the fifth?
Monthly interest uses the lowest balance between the close of the fifth day and month-end. A deposit credited after the fifth normally starts earning from the following month.
How much will ₹1.5 lakh a year grow in 15 years?
At a constant 7.1% rate with each annual deposit made by April 5, ₹22.5 lakh of contributions grows to about ₹40.68 lakh. Future rate changes will alter the result.
Is PPF interest taxable?
Eligible PPF interest and maturity proceeds are tax-exempt under the applicable provisions. Contribution deductions depend on your tax regime, available limit and eligibility.
Does the new tax regime give a PPF contribution deduction?
The new tax regime generally does not allow the commonly referenced Section 80C contribution deduction. The calculator includes it only when you select the old-regime estimate.
Can a PPF account continue after 15 years?
Yes. Subject to scheme conditions, it may continue without deposits or be extended with deposits in five-year blocks. Extension with deposits requires the prescribed option within the allowed time.
Is a monthly PPF deposit worse than an annual deposit?
An equal annual amount deposited by April 5 earns for longer and produces a higher estimate. Monthly deposits may fit salary cash flow better and still support consistent saving.
How accurate is this PPF calculator?
It accurately applies the entered assumptions and monthly-balance timing model. Actual results differ when government rates, deposit dates, withdrawals, rounding or account status change.
