PPF Calculator Guide: Maturity Value After 15, 20 & 30 Years (7.1% Rate)

Public Provident Fund is the closest thing India's tax system offers to a guaranteed, government-backed, fully tax-free long-term investment — and it's also one of the most misunderstood, because the rules around extensions, partial withdrawals, and (as of a 2024 amendment) minor accounts have changed enough that older guides now give incorrect advice. This guide covers the exact maturity math at every contribution level and every rule that actually matters for planning your account, not just the headline 7.1% rate.

This is a companion deep-dive to the broader India personal finance guide on this site. If you're deciding between PPF and market-linked options for your Section 80C allocation, see the comparison section below, model the equity side with the SIP calculator, and check our 10-year Nifty SIP returns data for the market-linked side of that comparison. If PPF is one part of a broader regime decision, the income tax calculator shows how it fits into your overall tax picture.

Current PPF Interest Rate: 7.1% Since April 2020

The Finance Ministry confirmed the PPF rate remains 7.1% per annum for the July–September 2026 quarter, unchanged from the previous quarter — this is now the longest stable run for the PPF rate in recent history, holding steady since April 2020. Interest is compounded annually and calculated on the lowest balance between the 5th and last day of each month, which is why contributing before the 5th of the month maximizes interest for that month's deposit.

PPF and other small savings scheme rates aren't set arbitrarily — they follow a formula recommended by the Shyamala Gopinath Committee (2011), linking each scheme's rate to the average yield on comparable-maturity government securities (G-Secs) over the preceding three months, with PPF specifically carrying a 25 basis point spread over its reference G-Sec yield. This means the rate can, in principle, move each quarter, even though it has held flat for six years — a useful piece of context when a maturity projection spans 15–30 years and assumes a constant rate throughout.

PPF Maturity Value at ₹1.5 Lakh/Year (Maximum Contribution)

Contributing the maximum ₹1.5 lakh per year — the same amount that exhausts your full Section 80C limit — produces the following maturity corpus at 7.1%:

The 20-year row is highlighted because it's the most common real-world horizon — investors who start a PPF account in their late 20s or early 30s and extend once tend to land here around typical retirement-planning ages. Notice that interest earned exceeds total contribution by the 20-year mark and grows to more than double your contribution by 30 years — the power of compounding at a fixed, guaranteed rate becomes dramatic only in PPF's later years, which is exactly why extending rather than withdrawing at the 15-year mark is usually the higher-value choice for anyone who doesn't need the money immediately.

PPF Maturity at Other Contribution Levels

Not every investor maxes out the ₹1.5 lakh annual limit — here's how the 15-year maturity value scales at other common contribution amounts:

The maturity value scales almost linearly with contribution amount at a fixed tenure, since every contribution level compounds at the same 7.1% rate over the same 15 years — the maximum-contribution row is highlighted simply because it's the reference point every other row can be compared against proportionally. If ₹1.5 lakh/year isn't feasible, contributing what you can consistently still captures the same guaranteed rate; PPF has no minimum-contribution penalty beyond the ₹500/year floor required to keep the account active.

What Happens at 15-Year Maturity: Three Choices

When a PPF account reaches its 15-year maturity, the account holder has three options, and the choice materially affects future flexibility:

• Withdraw everything and close the account. The full maturity value, fully tax-free, is available with no further obligations.
• Extend in a 5-year block WITH continued contributions. You keep contributing (up to ₹1.5L/year) and keep earning 7.1% on the growing balance. Withdrawal during this extension period is capped at 60% of the balance at the time of extension, limited to one withdrawal per year.
• Extend in a 5-year block WITHOUT further contributions. The existing balance keeps earning 7.1% with no new deposits required. This option allows unlimited withdrawal amount, one withdrawal per year — meaningfully more flexible than the with-contribution extension.

Loans and Partial Withdrawals Before Maturity

PPF isn't fully locked for the entire 15 years — two mechanisms provide access to funds before maturity, though both come with restrictions that make PPF unsuitable as an emergency fund on its own.

The partial withdrawal row is highlighted because it's the mechanism most account holders actually use for a genuine mid-tenure need (a child's education expense, a medical emergency, a down payment shortfall) rather than the loan facility, which carries an interest cost on top of forgoing the 7.1% that balance would otherwise be earning. Neither mechanism should be treated as a substitute for a proper emergency fund — PPF's tax-free compounding is most valuable when left untouched for its full tenure, and each withdrawal or loan interrupts that compounding on the amount removed.

Minor PPF Accounts: A Rule Change Most Parents Don't Know About

Many parents open a PPF account for a child assuming it earns the standard 7.1% rate from day one — a 2024 rule change means that's no longer automatically true.

• Only a natural or legal guardian who is an Indian citizen can open and operate a PPF account for a minor, until the child turns 18.
• Only one PPF account per minor is allowed, and it must be opened by either the mother or the father — not both separately.
• Grandparents cannot open a minor's PPF account unless they are the child's legal guardian.
• Since the October 2024 amendment, minor PPF accounts earn interest only at the Post Office Savings Account (POSA) rate — currently around 4% — until the child turns 18. The standard 7.1% PPF rate only applies after the account converts to the child's name at adulthood.
• Once the child turns 18, the account must be formally transferred into their own name, at which point it starts earning the regular PPF rate going forward.

NRI PPF Rules: What Changed in 2024

PPF eligibility and treatment for Non-Resident Indians tightened significantly in a 2024 amendment that many existing account holders may not be aware of.

• NRIs cannot open a new PPF account. PPF is available only to resident Indian citizens at the time of account opening.
• If a resident Indian PPF account holder later becomes an NRI, they can continue operating the existing account until its original maturity, but cannot extend it further beyond that maturity date.
• Since October 1, 2024, NRI-held PPF accounts no longer earn any interest — a major change from the previous treatment, where NRI accounts continued earning the standard rate until maturity.

If you hold a PPF account and are considering a move abroad, this is a genuinely important planning consideration: an account that stops earning interest the moment your residency status changes is a materially different asset than the same account held by a resident, and the maturity projections in this guide assume continuous resident status throughout the tenure.

PPF vs. ELSS vs. Tax-Saving FD: Which Section 80C Instrument Wins

PPF is one of several instruments competing for the same ₹1.5 lakh Section 80C limit, and the right choice depends heavily on your risk tolerance and time horizon.

The PPF row is highlighted because it's the only one of the three offering a genuinely guaranteed return with zero tax anywhere in the lifecycle — ELSS offers higher expected returns but with real market risk and a partial tax on gains, while tax-saving FD offers a similar guarantee to PPF but with fully taxable interest that erodes its real return, especially for taxpayers in the 30% bracket. See our FD vs. mutual funds comparison for a deeper look at that specific trade-off beyond just the tax-saving 5-year FD variant. A commonly recommended split for investors under 45 with a 5+ year horizon is roughly 60% ELSS / 40% PPF within the 80C limit — capturing growth potential while keeping a guaranteed, tax-free floor, and our SIP vs. lump sum guide covers how to actually invest the ELSS portion of that split. Investors closer to retirement, or those who specifically need PPF's status as an asset that cannot be attached by courts or creditors, often weight more heavily toward PPF despite the lower headline return.

How PPF Interest Actually Compounds: The Month-Level Detail

Most PPF maturity figures assume a single annual contribution at the start of the year, but real contribution patterns vary, and the exact timing changes your actual return meaningfully.

• Interest is calculated monthly, on the lowest balance between the 5th and the last day of the month — but credited to your account only once a year, at the end of the financial year.
• Contributing before the 5th of the month means that month's deposit earns interest for the full month. Contributing on the 6th or later means you lose that entire month's interest on the new deposit.
• A single lump-sum contribution on April 1st (the first working day of the financial year) earns a full year of interest on the entire amount — this is the single best-timed contribution pattern for maximizing returns, assuming you have the full ₹1.5 lakh available upfront rather than needing to save toward it monthly.
• Monthly contributions of ₹12,500 (totaling ₹1.5 lakh/year) earn slightly less than the lump-sum approach, because later months' contributions have fewer months remaining to earn interest within that financial year — the gap is usually a few hundred to low thousands of rupees per year, small in absolute terms but compounds noticeably over a 15+ year tenure.

PPF Interest Rate History: From 4.8% to 12% to Today's 7.1%

Today's 7.1% can look unimpressive against ELSS's 12-15% historical equity returns, but PPF's own rate history shows it hasn't always been a modest guaranteed return — understanding that history helps set realistic expectations for where the rate could move over a 15-30 year holding period.

The 1986-2000 "golden period" is highlighted because it's the historical high-water mark most long-time PPF investors remember — a sustained 12% guaranteed, tax-free rate for over a decade, nearly double today's rate. Since 2016, the rate has been reviewed quarterly against a formula tied to government security yields rather than set administratively, which is both why it moves less dramatically than in past decades and why the current 7.1% has proven unusually stable rather than a permanent floor — a future rate-cycle shift (in either direction) remains structurally possible under the same formula that's kept it flat since 2020.

PPF vs. Sukanya Samriddhi Yojana: Which for a Daughter's Future?

Parents saving specifically for a girl child often weigh PPF against Sukanya Samriddhi Yojana (SSY), a scheme designed exclusively for this purpose — and given the minor-account interest rate change covered above, this comparison matters more than it used to.

The maturity row is highlighted because SSY's structure is purpose-built around a girl's likely life milestones (higher education, marriage) in a way PPF's generic 15-year cycle isn't, and critically, SSY doesn't carry the reduced-rate restriction that now applies to minor PPF accounts — meaning for a girl child specifically, SSY's 8.2% throughout comfortably outperforms a minor PPF account's blended rate (4% until 18, then 7.1%) for the exact same tax treatment. For a son, PPF (opened as a minor account, later transferred to his name at 18) remains the closest equivalent government-backed option, since SSY isn't available. Many financial planners recommend SSY as the default choice for a daughter's long-term corpus specifically because of this rate gap, reserving PPF for goals SSY's structure doesn't fit (e.g., the parent's own retirement corpus, where the minor-account rate reduction doesn't apply at all).

PPF vs. NPS: Two Government-Backed Retirement Options Compared

Beyond the 80C-competing instruments above, PPF is also frequently compared against NPS (National Pension System) for long-term retirement planning specifically, since both are government-backed and both offer tax advantages — but they work very differently.

The tax deduction row is highlighted because it's the most actionable difference for someone still deciding where to direct new savings: NPS offers an additional ₹50,000 deduction entirely separate from the ₹1.5 lakh 80C limit that PPF, ELSS, and tax-saving FD all compete for — meaning a taxpayer already maxing out 80C elsewhere can add NPS contributions purely for this extra deduction without displacing their existing PPF or ELSS allocation. The trade-off is liquidity and structure: PPF matures in full after 15 years (extendable at your discretion), while NPS locks until age 60 and even then forces 40% into an annuity rather than releasing the full corpus.

How to Open a PPF Account: Where and What You Need

Opening a PPF account is straightforward, but a few practical details affect which option makes sense for you.

• Where to open: Any nationalized bank, most major private banks, and all post offices offer PPF accounts. Online account opening is available through most bank net-banking or mobile app platforms if you already hold a savings account there.
• Documents required: PAN card, Aadhaar card, a recent passport-size photograph, and address proof. For a minor's account, the guardian's KYC documents plus the child's birth certificate are required.
• Minimum to open: As little as ₹100–500 depending on the institution, though the practical minimum to keep the account active for the year is ₹500 in total annual contribution.
• One account per person: You cannot hold multiple PPF accounts in your own name (excluding a separate account you operate on behalf of a minor child). Attempting to open a second account in your own name is against the rules and can result in the second account being closed without interest once discovered.
• Transferring between institutions: A PPF account can be transferred from a post office to a bank or between banks without losing accumulated interest or resetting the maturity clock — useful if you relocate or prefer consolidating accounts with your primary bank.

Why PPF Matters More for the Self-Employed

Salaried employees usually have EPF (Employees' Provident Fund) as a mandatory, employer-linked retirement savings vehicle — self-employed professionals and freelancers don't, which makes PPF disproportionately important for this group as their primary guaranteed, tax-free long-term savings option.

• No employer match, but no employer dependency either. EPF requires an employer relationship; PPF can be opened and funded entirely independently, which is exactly what self-employed income needs.
• Irregular income compatibility. Because PPF only requires ₹500/year minimum with no fixed monthly obligation, it accommodates the income variability common to freelance and consulting work better than a fixed monthly EPF-style deduction would.
• Creditor protection matters more for business owners. PPF balances cannot be attached by courts or creditors even in bankruptcy proceedings — a meaningful protection for anyone running a business with personal liability exposure, in a way salaried employees with steady EPF contributions may weigh less heavily.
• Combine with NPS for the extra deduction. Self-employed individuals can also open an NPS account and claim the same 80CCD(1B) additional ₹50,000 deduction covered above, stacking with PPF's 80C allocation for a larger total tax-advantaged contribution than either instrument alone provides.

For a freelancer or business owner without access to EPF, a disciplined PPF contribution — even below the ₹1.5 lakh maximum — functions as the closest available substitute for the forced retirement savings a salaried job would otherwise provide automatically.

Common PPF Mistakes to Avoid

• Contributing after the 5th of the month, repeatedly. As covered above, this is a small but entirely avoidable interest loss that compounds over 15+ years.
• Opening a second PPF account. Only one account per person is permitted; a second account (excluding a minor's account you operate) violates the rules.
• Assuming a minor's account earns 7.1% before the child turns 18. As covered above, it earns the lower POSA rate until the child reaches adulthood — a fact many parents only discover at withdrawal time.
• Missing the ₹500 minimum annual contribution. An account that falls below this becomes "discontinued" and requires a penalty payment plus the missed contributions to reactivate — don't let a dormant account happen by accident.
• Treating PPF as an emergency fund. The partial withdrawal and loan mechanisms exist, but both interrupt compounding and come with restrictions — a separate liquid emergency fund is a better first line of defense before touching PPF.
• Not deciding on extension type before the maturity deadline. Failing to actively choose an extension option within a year of maturity can default the account into a specific treatment depending on your bank or post office's policy — confirm your account's default behavior before maturity approaches rather than assuming.

Worked Example: Starting a PPF Account at Different Ages

Because PPF's biggest gains come from compounding in the later years, the age at which you start — and whether you extend past the base 15-year tenure — matters more than most people intuit.

• Starting at 25, contributing ₹1.5L/year, extending twice to 25 years: matures at age 50 with a corpus of approximately ₹1.03 crore.
• Starting at 35, contributing ₹1.5L/year, taking the base 15-year term only: matures at age 50 with a corpus of approximately ₹40.68 lakh.
• Starting at 25 and extending three times to 30 years: matures at age 55 with a corpus of approximately ₹1.54 crore — more than triple the 15-year corpus for the same annual contribution, purely from extended compounding.

The ten-year head start in the first scenario more than doubles the eventual corpus compared to the second scenario, despite both investors contributing the same ₹1.5 lakh annually — a direct illustration of why starting a PPF account early, even with a smaller contribution than the maximum, tends to outperform starting later with the intention to "catch up" by maxing out from a later start date.

Will the PPF Rate Change? What Long-Term Investors Should Expect

Every maturity projection in this guide assumes 7.1% holds constant for the full tenure, which is a reasonable planning assumption but not a guarantee — it's worth understanding how much a rate change could actually move your outcome. Because the rate is reviewed quarterly against a G-Sec-linked formula rather than fixed for the scheme's lifetime, a sustained shift in government bond yields would eventually show up in the PPF rate too, as it has repeatedly over the scheme's history — from the 1986-2000 12% peak down to today's 7.1%.

In practice, a rate change doesn't retroactively affect interest already credited — it only changes the rate applied going forward from the quarter it takes effect. A long-tenure PPF investor holding through multiple decades should expect the rate to drift with the broader interest-rate cycle rather than assuming today's 7.1% is either a permanent floor or a permanent ceiling; the six-year stability since April 2020 is unusual by the scheme's own historical standards, not the norm.

Frequently Asked Questions

What is the current PPF interest rate in 2026?

7.1% per annum, unchanged since April 2020 and confirmed for the July–September 2026 quarter by the Finance Ministry. The rate is reviewed quarterly based on a formula linked to government security yields, though it has remained stable for six years.

How much will ₹1.5 lakh per year in PPF grow to in 15 years?

Approximately ₹40.68 lakh at the current 7.1% rate, against a total contribution of ₹22.5 lakh over 15 years — roughly ₹18.18 lakh in tax-free interest earned.

Can I withdraw my PPF money before 15 years?

Partial withdrawal is allowed from the 7th year onward, capped at 50% of the balance at the end of the 4th preceding year (or the immediately preceding year, whichever is lower), limited to one withdrawal per year. A loan against your PPF balance is separately available from the 3rd to 6th year.

Do minor PPF accounts earn the full 7.1% interest rate?

No, as of the October 2024 amendment, minor PPF accounts earn only the Post Office Savings Account rate (around 4%) until the child turns 18, after which the account transfers to their name and starts earning the standard 7.1% PPF rate.

Can NRIs open or continue a PPF account?

NRIs cannot open a new PPF account. A resident who later becomes an NRI can continue an existing account until its original maturity but cannot extend it further, and since October 1, 2024, NRI-held PPF accounts no longer earn any interest.

Is PPF or ELSS better for Section 80C tax saving?

It depends on risk tolerance and horizon. ELSS offers higher historical returns (12–15% CAGR) with market risk and a 3-year lock-in; PPF offers a guaranteed 7.1%, fully tax-free, with a 15-year lock-in. Many advisors recommend splitting the ₹1.5 lakh limit — roughly 60% ELSS, 40% PPF — for investors under 45 with a 5+ year horizon.

Can I have more than one PPF account?

No, only one PPF account is permitted per person (excluding a separate account operated on behalf of a minor child). Opening a second account in your own name violates the rules and can result in it being closed without interest once discovered.

What is the difference between PPF and NPS for retirement savings?

PPF offers a fixed, guaranteed 7.1% return with a 15-year lock-in and fully tax-free maturity. NPS offers market-linked returns (historically higher for the equity-heavy option) but locks until age 60 and forces 40% of the corpus into a taxable annuity at withdrawal. NPS also offers an additional ₹50,000 deduction under Section 80CCD(1B), separate from the ₹1.5 lakh 80C limit PPF competes for.
