If you want to know exactly how much your PPF account will be worth at maturity, a PPF calculator gives you the answer in seconds instead of forcing you to work through fifteen years of compounding by hand. Enter your yearly or monthly contribution, the tenure, and the applicable interest rate, and the calculator instantly shows your total investment, the interest earned, and the final maturity value, all of which is completely tax-free under the current rules.

This guide covers everything a PPF calculator alone cannot: the exact formula used behind the scenes, how the SBI PPF calculator and post office PPF calculator compare, the current interest rate, tax benefits under Section 80C, withdrawal and loan rules, and the mistakes that quietly cost investors lakhs of rupees over a 15-year tenure

What Is a Public Provident Fund (PPF)?

The Public Provident Fund is a government-backed, long-term savings scheme launched by the Ministry of Finance in 1968 and currently governed by the PPF Scheme, 2019. It is designed to encourage disciplined, long-term savings while offering a guaranteed, sovereign-backed return that does not fluctuate with the stock market.

PPF is open to any resident individual, either in their own name or on behalf of a minor child, and can be opened at a post office, the State Bank of India, or most other nationalised and select private banks. The account carries a mandatory lock-in of 15 years, though it can be extended indefinitely in blocks of five years once it matures.

Three features make PPF one of the most trusted instruments in Indian retail savings:

  • EEE tax status. Your contribution, the interest earned, and the maturity amount are all exempt from income tax, a rare combination among Indian savings products.
  • Sovereign guarantee. Because it is backed directly by the Government of India, PPF carries no credit or default risk, unlike a corporate fixed deposit.
  • Annual compounding on the lowest monthly balance. Interest is calculated every month on the lowest balance between the 5th and the last day of that month, then compounded and credited once a year.

PPF Calculator Formula Explained

A PPF calculator online uses a standard compound interest formula built around annual contributions:

M = P × [(1 + i)^n − 1] / i × (1 + i)

Where:

  • M = Maturity value
  • P = Annual investment amount
  • i = Annual rate of interest (in decimal form)
  • n = Number of years (typically 15)

The extra (1 + i) at the end accounts for the fact that most PPF calculators, including bank and post office tools, assume the deposit is made at the start of the financial year rather than the end, so that year’s contribution also earns a full year of interest.

Worked Example

Suppose you invest ₹1,00,000 every year for 15 years at the current PPF interest rate of 7.1% per annum, compounded annually.

ParticularsAmount
Annual investment₹1,00,000
Tenure15 years
Interest rate7.1% p.a.
Total amount invested₹15,00,000
Total interest earned (approx.)₹12,12,139
Maturity value (approx.)₹27,12,139

Notice that the interest earned actually exceeds your total contribution over 15 years. This is the compounding effect that a manual calculation is most likely to get wrong, since even a small rounding error in year one carries through all fifteen years.

How to Use the PPF Calculator

Using the PPF calculator on this page takes less than a minute:

  • Enter your investment amount. This can be a yearly lump sum or a monthly figure; the calculator converts monthly PPF calculator inputs into an annual equivalent automatically.
  • Choose your tenure. The default is 15 years, but you can extend this in 5-year blocks to see how a longer tenure changes your final corpus.
  • Check the interest rate. The calculator is pre-filled with the current government-notified rate, but you can adjust it to model a rate change in future quarters.
  • View your results. You will instantly see your total investment, total interest earned, and maturity value, along with a year-by-year growth table.

Because PPF interest compounds annually on a balance that itself changes with your monthly deposit timing, doing this by hand is genuinely error-prone. This is exactly why a PPF calculator online, rather than a rough spreadsheet estimate, gives you a more dependable number to plan around.

Current PPF Interest Rate 2026

<cite index=”4-1″>The PPF interest rate for the July-September 2026 quarter has been retained at 7.1% per annum, compounded annually, as announced by the Ministry of Finance on 30 June 2026</cite>. This rate has not changed since April 1, 2020, making it one of the longest stretches of stability in the scheme’s recent history.

QuarterPPF Interest Rate
April 2020 – June 2026 (unchanged)7.10% p.a.
July 2019 – March 20207.90% p.a.
July–Sept 2026 (current)7.10% p.a.

<cite index=”4-1″>The minimum annual deposit remains ₹500, while the maximum investment limit stays at ₹1.5 lakh per financial year</cite>. Because the government reviews small savings rates every quarter, it is worth rechecking the current rate before relying on a projection that spans several years.

A detail most PPF calculator tools skip: since interest is based on your lowest balance between the 5th and last day of each month, depositing before the 5th of any month, rather than later, ensures that month’s deposit earns interest for the entire month instead of losing it.

PPF Calculator: SBI vs Post Office vs Other Banks

A common point of confusion is whether an SBI PPF calculator, a post office PPF calculator, or a calculator from any other bank gives a different result. It does not, and here is why:

ParticularsSBI PPF CalculatorPost Office PPF CalculatorOther Bank PPF Calculators
Interest rate usedSame government-notified rateSame government-notified rateSame government-notified rate
FormulaIdentical compound interest formulaIdentical compound interest formulaIdentical compound interest formula

Online account managementAvailable via net banking/YONOLimited; largely branch-based, though India Post has been expanding paperless facilitiesVaries by bank
Loan and withdrawal rulesIdentical, set nationallyIdentical, set nationallyIdentical, set nationally

The PPF interest rate is fixed centrally by the Ministry of Finance and applies uniformly whether your account sits at SBI, a post office, or any other authorised bank. The only real differences between institutions are convenience factors, such as net banking access, branch density, and how easily you can link the account to online payments, not the return you actually earn. If you are deciding where to open an account, a post office branch near your home versus an SBI account you already operate through YONO is largely a matter of convenience rather than returns.

PPF Tax Benefits Under Section 80C

PPF remains one of the most tax-efficient instruments available to Indian residents under the old tax regime:

  • Deduction on contribution. <cite index=”35-1″>Investments up to ₹1.5 lakh per financial year qualify for deduction under Section 80C, subject to a combined annual limit across all Section 80C, 80CCC and 80CCD(1) investments together</cite>.
  • Tax-free interest. The interest credited to your PPF account every year is entirely exempt from income tax, with no separate reporting required beyond your return filing.
  • Tax-free maturity. The full maturity amount, including both principal and accumulated interest, is exempt from tax when withdrawn.
  • Section 123 transition. Following the Income Tax Act, 2025, this deduction is now available under Section 123, though the ₹1.5 lakh combined limit and the underlying benefit remain unchanged.

Because the 80C deduction is only available under the old tax regime, if you have opted for the new tax regime under the Income Tax Act, you will not be able to claim this deduction, even though the interest and maturity proceeds continue to be tax-exempt regardless of the regime you choose.

PPF Withdrawal Rules: Loans, Partial Withdrawal and Premature Closure

A PPF account is not entirely locked for all 15 years. The scheme provides three structured, stage-wise ways to access your money early, each governed by rules set nationally under the PPF Scheme, 2019.

Loan Against PPF (Years 3 to 6)

<cite index=”30-1″>A loan facility is available from the 3rd financial year up to the 6th financial year</cite> of your account. This lets you borrow against your balance without disturbing the compounding on your existing deposit, and is usually a better option than an early withdrawal if you need short-term liquidity.

Partial Withdrawal (From Year 7 Onward)

From the 7th financial year, you can make one partial withdrawal per year. The amount you can withdraw is generally capped at 50% of the balance at the end of the 4th preceding year, or the immediately preceding year, whichever is lower. You will need to submit Form C at your bank or post office to initiate this.

Premature Closure (After 5 Years, Specific Grounds Only)

Premature closure is permitted only after 5 completed financial years, and only for specific reasons such as life-threatening medical treatment of the account holder or dependents, or higher education expenses of the account holder or their children, supported by documentary proof. A premature closure typically reduces the applicable interest rate by 1% for the entire tenure the account was held, so it should be treated as a last resort rather than a routine option.

At Maturity (15 Years)

Once the account matures, you have three choices: withdraw the full amount tax-free, extend the account for another 5-year block with fresh contributions, or extend it without making further deposits while still earning interest on the existing balance.

PPF vs Other Popular Savings Options

If you are deciding how PPF fits alongside other instruments, here is how it compares on the factors that matter most:

InstrumentCurrent Rate (approx.)Lock-inTax TreatmentRisk
PPF7.1% p.a.15 yearsEEE (fully tax-free)Sovereign guarantee, zero risk
5-Year Post Office / Bank Tax-Saving FD6.9% to 7.5% p.a.5 yearsInterest taxableLow risk
National Savings Certificate (NSC)Around 7.7% p.a.5 yearsInterest taxable (reinvested portion eligible for 80C)Sovereign guarantee
Sukanya Samriddhi Yojana (for girl child)Around 8.2% p.a.Until beneficiary turns 21EEE (fully tax-free)Sovereign guarantee
Equity Mutual Fund SIPMarket-linked, no guaranteeNo fixed lock-in (barring ELSS)Capital gains tax on redemptionMarket risk

PPF sits firmly on the conservative end of this spectrum: lower liquidity than a bank FD but a materially better tax outcome, and a longer horizon than most instruments except Sukanya Samriddhi Yojana. If you also want to compare a market-linked option, our SIP Calculator shows how a growing monthly investment could perform against PPF’s fixed, tax-free return over the same period. For a side-by-side look at guaranteed-return options, our Fixed Deposit Calculator lets you compare a 5-year tax-saving FD against a 15-year PPF using your own numbers.

PPF Calculator Monthly Investment: Year-Wise Growth Table

Many investors search for a PPF calculator monthly view rather than an annual one, since salaried contributions are usually monthly. Here is how a monthly contribution of ₹12,500 (₹1,50,000 per year, the maximum permitted limit) grows at 7.1% per annum over a 15-year tenure:

YearAnnual Deposit (₹)Cumulative Investment (₹)Approx. Balance at Year End (₹)
11,50,0001,50,0001,60,650
31,50,0004,50,0005,17,395
51,50,0007,50,0009,07,914
71,50,00010,50,00013,35,847
101,50,00015,00,00020,72,326
121,50,00018,00,00026,29,004
151,50,00022,50,00036,67,724

Figures are indicative, based on a constant 7.1% assumed rate throughout the tenure, and will vary if the government revises the rate in future quarters. This is precisely why running your own numbers through the PPF calculator on this page, using the interest rate valid at the time, gives you a more reliable estimate than relying on a static table.

Common Mistakes to Avoid With PPF

  • Depositing after the 5th of the month. You lose an entire month of interest on that deposit if it is credited after the 5th, since the lowest balance rule looks at the 5th-to-month-end window.
  • Assuming any bank offers a higher PPF rate. The rate is identical everywhere; do not switch accounts chasing a better return that does not exist.
  • Forgetting Form H at maturity. If you want to extend your account with fresh contributions after 15 years, you must submit Form H within one year of maturity, or the account defaults to an extension without further deposits.
  • Treating premature closure as a routine option. The 1% interest penalty and restricted grounds mean PPF should be planned as a genuinely long-term commitment from day one, not a flexible short-term parking spot.
  • Ignoring the ₹1.5 lakh combined 80C limit. If you already claim 80C benefits through EPF, ELSS, or life insurance, additional PPF contributions beyond the combined ₹1.5 lakh ceiling do not bring any extra tax deduction, even though they still earn tax-free interest.

Why Use an Online PPF Calculator

Manually projecting a 15-year PPF corpus means tracking annual compounding, the timing of your deposits, and the current government-notified rate, and a single arithmetic slip early in the tenure compounds into a materially wrong final number. An online PPF calculator gives you:

  • Instant, accurate maturity projections using the correct compound interest formula, without manual calculation errors.
  • The ability to compare tenures and contribution amounts side by side before committing to a fixed monthly or annual deposit.
  • A realistic starting point for broader retirement planning, since PPF often works alongside other long-term instruments rather than in isolation.

If PPF is one part of a larger retirement or long-term savings plan, it helps to look at your full financial picture together. Our Gratuity Calculator can help you estimate a lump-sum payout you may receive at retirement, which you could then route into a PPF account for a further tax-free return. If you are weighing PPF against a shorter, guaranteed-return option, the Fixed Deposit Calculator shows how the same amount would grow over 5 years instead of 15. For a deeper look at how compounding itself works across any principal and rate, our Compound Interest Calculator is a useful companion tool. And if you are managing a loan alongside your long-term PPF contributions, our EMI Calculator can help you balance monthly obligations against your savings goals. Freelancers and small business owners investing surplus income into PPF may also find our GST Calculator useful for related compliance work.

Frequently Asked Questions

The PPF interest rate for the July-September 2026 quarter is 7.1% per annum, compounded annually. This rate has remained unchanged since April 1, 2020, though the government reviews and can revise small savings rates every quarter.

PPF maturity is calculated using the compound interest formula M = P × [(1 + i)^n − 1] / i × (1 + i), where P is your annual investment, i is the annual interest rate, and n is the number of years. Interest is compounded annually but calculated monthly on the lowest balance between the 5th and last day of each month.

No. Both use the same government-notified interest rate and the identical compound interest formula. The only differences are around account convenience, such as online banking access, not the actual return you earn.

No. Both use the same government-notified interest rate and the identical compound interest formula. The only differences are around account convenience, such as online banking access, not the actual return you earn.

You can invest a minimum of ₹500 and a maximum of ₹1.5 lakh in a PPF account per financial year. Deposits can be made as a lump sum or in instalments, including monthly contributions.

Yes, in a structured way. A loan facility is available from the 3rd to the 6th financial year. Partial withdrawals are permitted from the 7th financial year onward, subject to a cap. Premature closure of the account is allowed only after 5 years, and only for specific reasons such as medical treatment or higher education.

No. PPF falls under the Exempt-Exempt-Exempt (EEE) category, meaning your contribution qualifies for a Section 80C deduction (up to ₹1.5 lakh, old tax regime only), the interest earned is fully tax-free, and the maturity amount is also completely exempt from tax.

Yes. You can extend your account indefinitely in blocks of 5 years. If you want to continue making contributions during the extended block, you must submit Form H within one year of the original maturity date; otherwise, the account is extended without further deposits by default.

PPF generally offers a better tax-adjusted return than a taxable fixed deposit because of its EEE status, but it comes with a much longer 15-year lock-in compared to an FD’s flexible tenures. FDs suit shorter-term goals and liquidity needs, while PPF suits long-term, retirement-oriented savings.

No, non-resident Indians cannot open a new PPF account. However, if an NRI opened a PPF account while they were still a resident Indian, they can continue operating that account until its original 15-year maturity, subject to prevailing rules.

Conclusion

PPF remains one of the few instruments in India that combines a government guarantee, a genuinely tax-free return, and disciplined long-term compounding, provided you understand exactly how the maturity value builds up over 15 years. Use the PPF calculator above to test different contribution amounts and tenures against the current 7.1% rate, and revisit your numbers each time the government announces a new quarterly rate, so your retirement or long-term savings plan is always built on an accurate, up-to-date projection rather than a rough guess.
