PPF Calculator India - What Your Money Actually Does Over 15 Years
Most people open a Public Provident Fund (PPF) account for the Section 80C tax break and then forget about it. That's not wrong - the ₹46,800 tax saving at 30% bracket is real money. But the bigger story is the compounding. As India's most trusted government-backed savings scheme, PPF offers 7.1% with full EEE tax exemption - quietly making it one of the most powerful risk-free wealth-building instruments available.
Here's a number that surprises most people: invest ₹1.5 Lakh per year from age 30 to 45 - that's ₹22.5 Lakh invested - and your PPF maturity amount is approximately ₹40.68 Lakh. You've more than doubled your money tax-free, with zero market risk and full government backing. No equity fund guarantees that. PPF doesn't need to beat the Sensex. It just needs to reliably, predictably compound - and it does.
How This PPF Calculator Works
The calculator uses the official PPF interest logic: interest is computed on the lowest balance between the 5th and last day of each month, then credited annually on March 31st. For yearly investments (assumed deposited before April 5th), the full year's deposit earns a full year of interest. For monthly mode, each monthly deposit earns interest from the month of deposit through March.
PPF Calculator India - PPF vs FD vs RD vs ELSS: The Full Picture
PPF's 7.1% doesn't sound impressive next to ELSS's potential 14% or even NPS equity's 12%. But returns alone don't tell the story - tax treatment, risk and liquidity together determine what you actually walk away with. Here's the comparison table every Indian investor needs:
| Factor | PPF | Fixed Deposit | Recurring Deposit | ELSS Mutual Fund |
|---|---|---|---|---|
| Returns | 7.1% (government-set) | 6.5–8.5% (bank-specific) | 6–7.5% | 10–14% (historical, variable) |
| Tax on Returns | 100% tax-free (EEE) | Fully taxable as income | Fully taxable as income | LTCG 10% above ₹1.25L/yr |
| Section 80C | Yes - up to ₹1.5L | 5-yr FD only | No | Yes - up to ₹1.5L |
| Effective Post-Tax Return (30% slab) | 7.1% (tax-free = full return) | ~4.9–5.9% (after 30% tax) | ~4.2–5.2% | ~10–13% (after LTCG) |
| Risk | Zero - government-backed | Low (DICGC cover ₹5L) | Low | Medium–High (equity market) |
| Lock-in | 15 years (partial from yr 7) | 1–10 years (varies) | Typically 1–3 years | 3 years (shortest 80C lock-in) |
| Best For | Long-term, tax-free, risk-free wealth building | Short-term guaranteed returns | Disciplined monthly saving | Long-term high-growth with some risk tolerance |
Notice the effective post-tax return column. A 30% taxpayer earning 7.5% FD interest actually keeps only about 5.25% after tax. PPF's 7.1% is tax-free - making it effectively better than an FD paying up to ~10.1% for the same taxpayer. That's not a small difference.

PPF Calculator India - The April 5th Rule: How Much Are You Leaving Behind?
This is the single most important tactical tip in PPF investing - and most people get it wrong every year. Here's how it works and why it matters more than you think.
The Rule in Plain English
PPF interest is computed on the minimum balance between the 5th and last day of each month. This means: whatever is in your account on the 5th of a month is the balance that earns interest for that month. Anything deposited after the 5th earns zero interest for that month - it starts earning only from the next month.
| Deposit Timing | Months Earning Interest (Year 1) | Impact Over 15 Years | Verdict |
|---|---|---|---|
| April 1–5 (Best) | 12 months full year | Maximum corpus ~₹40.68L | Optimal |
| April 6–30 | 11 months (April lost) | ~₹22,000–30,000 less over 15 yrs | Avoid if possible |
| May 1–5 | 11 months (no change from Apr 6) | Same cost as April after 5th | Suboptimal |
| Monthly SIP by 5th | 12 months (per deposit, from month of deposit) | ~₹22K less vs April lumpsum over 15 yrs | Good if lumpsum not possible |
| Monthly SIP after 5th | Each deposit loses 1 month | ~₹45K–₹60K less vs April lumpsum | Worst outcome |
The bottom line: if you can invest a lumpsum - do it between April 1st and April 5th. If you invest via monthly SIP, set standing instructions to debit before the 5th of each month. If your bank SIP date is the 10th or 15th - change it. That one admin task is worth ₹22,000–₹60,000 added to your PPF maturity amount, tax-free.
PPF Calculator India - What Happens After 15 Years? The Extension Power Table
Here's what almost nobody tells you about PPF: the best years often come after maturity. At 15 years, your corpus is fully matured - but you don't have to withdraw. Extending without any fresh contributions is one of the most underrated moves in Indian personal finance.
Why? Because you've already done the hard part. Your ₹40.68 Lakh corpus is now compounding at 7.1% with zero effort, zero risk and zero tax - on a larger base. The absolute interest earned each year now exceeds what you were contributing annually in the early years.
| After 15 Years | Starting Corpus | Extended +5 Yrs (₹1.5L/yr) | Extended +5 Yrs (No Contrib) | Extended +10 Yrs (₹1.5L/yr) | Extended +10 Yrs (No Contrib) | Extended +15 Yrs (No Contrib) |
|---|---|---|---|---|---|---|
| Max Invest ₹1.5L/yr | ₹40.68L | ₹66.58L | ₹57.33L | ₹1.03 Cr | ₹80.78L | ₹1.14 Cr |
You can set the duration slider all the way to 50 years in this PPF calculator India to see the full compounding trajectory - invested vs gains in the chart and a complete year-by-year schedule in the Schedule tab. For a complete retirement picture combining PPF with other instruments, read our retirement planning India guide, then pair this with our NPS Calculator and EPF Calculator to see how your full corpus stacks up across all three.
PPF vs NPS vs ELSS: Which 80C Investment Belongs in Your Portfolio?
PPF, NPS, and ELSS all qualify under Section 80C (old regime) up to ₹1.5 lakh, but they serve completely different purposes. Treating them as interchangeable alternatives misses the point - they are designed to be complementary layers.
| Factor | PPF | NPS | ELSS |
|---|---|---|---|
| Return type | Government-declared, fixed (7.1% Q1 FY27) | Market-linked equity + debt mix | Market-linked, equity-heavy |
| Historical returns | 7-8% nominal | 10-13% long-term | 12-15% long-term |
| Tax status | EEE (fully exempt) | Partial EEE (60% lump sum exempt; annuity taxable) | 12.5% LTCG on gains above ₹1.25L |
| Lock-in | 15 years | Till age 60 | 3 years (shortest) |
| Risk | Zero (sovereign guarantee) | Low-medium (diversified) | High (full equity) |
| Extra deduction | None beyond 80C | +₹50,000 under 80CCD(1B) | None beyond 80C |
| New regime benefit | None | 80CCD(2) employer contribution only | None |
The Three-Layer Approach Most Financial Planners Recommend
Layer 1 - PPF (Safety anchor): Max ₹1.5L/year for EEE tax-free compounding. The government-backed floor of your 80C allocation. Non-negotiable for conservative savers and anyone in the 30% slab where the EEE benefit is most powerful.
Layer 2 - NPS (Retirement booster): The additional ₹50,000 deduction under 80CCD(1B) is available only through NPS and only under the old regime. For a 30% slab taxpayer, this alone saves ₹15,600/year in tax at no additional investment beyond the deduction ceiling. Use the NPS corpus and pension projection to see how this extra deduction compounds into retirement.
Layer 3 - ELSS (Growth engine): If your 80C is not fully used by EPF contributions, PPF, and NPS, ELSS fills the remaining space with equity-linked growth. The 3-year lock-in is the shortest among all 80C instruments. Post-lock-in, gains above ₹1.25L/year attract 12.5% LTCG, still lower than most slab rates.
Is PPF Enough for Retirement by Itself?
At 7.1% and ₹1.5L/year for 25 years: approximately ₹1.03 crore corpus. Inflation-adjusted real return at 6% CPI: approximately 1.04%, barely positive. PPF alone is not enough for retirement for most urban Indians, but it is an essential low-risk layer within a diversified retirement plan. Pair it with EPF (mandatory), NPS (optional top-up), and equity SIP for a complete picture. For a deep dive into how NPS, EPF, and PPF compare across returns, tax treatment, lock-in, and withdrawal rules with full worked examples for each life stage, the complete comparison covers every decision point between these three instruments.
