PPF Calculator – See Exactly How Much Your Tax-Free PPF Will Be Worth After 15 Years

The Boring Investment That Actually Beats Most “Exciting” Options

PPF doesn’t make headlines. It doesn’t trend on Twitter. No YouTuber is making viral videos about it.

And yet, for a huge number of Indians – especially those in higher tax brackets – PPF is quietly one of the smartest financial decisions they can make. Tax-free returns. Government-backed safety. A forced saving mechanism that actually works. And returns that, once you factor in the tax advantage, beat most debt instruments comfortably.

This calculator shows you exactly what your PPF account will be worth at maturity – year by year, contribution by contribution – so you can see the full picture before you decide how much to put in.

How PPF Actually Works – The Basics

PPF (Public Provident Fund) is a savings scheme run by the Indian government. Here’s what makes it different from most other investments:

Tenure: 15 years. That’s the minimum lock-in period. You can extend it in blocks of 5 years after that, but you can’t close it before 15 years (with very limited exceptions).

Contribution: You can put in anywhere from ₹500 to ₹1,50,000 per year. You can make contributions in one lump sum or in instalments – monthly, quarterly, whatever works for you.

Interest Rate: Set by the government every quarter. Currently around 7.1% per annum, compounded annually. This rate has historically stayed in the 7-8% range, though it can change.

Tax Treatment: This is the big one. PPF is one of the very few investments in India that is completely tax-free at every stage – contributions get a deduction under Section 80C, the interest earned is tax-free, and the maturity amount is tax-free. No other common investment offers this triple tax exemption.

Safety: PPF is backed by the Government of India. It’s as safe as it gets in the Indian financial system.

How to Use the Calculator

Step 1 – Enter your annual contribution. How much are you planning to put into PPF each year? The maximum is ₹1,50,000. If you’re already maxing out Section 80C with other investments (like ELSS or life insurance premiums), you might want to put less here.

Step 2 – Set the expected interest rate. The current rate is 7.1%, but the government reviews it quarterly. For planning purposes, 7-7.5% is a reasonable assumption. The calculator uses compound interest to project your balance.

Step 3 – Choose your investment period. The minimum is 15 years. But if you’re young, you might want to see what happens at 20, 25, or even 30 years (with extensions).

The calculator shows you your year-by-year balance, total contributions, total interest earned, and your final maturity amount.

The Formula and a Worked Example

PPF uses annual compounding:

A = P × {(1 + r)^n – 1} / r

(This is the future value of annuity formula, since you’re making annual contributions)

Where:

• A – Maturity amount
• P – Annual contribution
• r – Annual interest rate as a decimal
• n – Number of years

Example:

You contribute ₹1,50,000 per year (the maximum) at 7.1% for 15 years.

r = 0.071 n = 15 P = 1,50,000

A = 1,50,000 × {(1.071)^15 – 1} / 0.071 A = 1,50,000 × {2.8102 – 1} / 0.071 A = 1,50,000 × 1.8102 / 0.071 A = 1,50,000 × 25.4958 A = ₹38,24,370

So you put in ₹22,50,000 over 15 years (₹1.5 lakhs × 15). You get back ₹38,24,370. The extra ₹15,74,370 is tax-free interest – money you earned without paying a single rupee of tax on it.

Now extend to 20 years (with a 5-year extension): A = 1,50,000 × {(1.071)^20 – 1} / 0.071 ≈ ₹59,00,000

Five extra years of contribution and compounding adds another ₹21 lakhs. Tax-free.

The Real Power: The Tax Advantage Explained

PPF’s true advantage becomes clear when you compare it to taxable investments earning similar returns.

Scenario: ₹1,50,000 invested annually for 15 years

In PPF (7.1%, tax-free):

• Total invested: ₹22,50,000
• Maturity amount: ₹38,24,370
• Tax paid on returns: ₹0
• Actual wealth created: ₹38,24,370

In a Bank FD (7.5%, fully taxable – 30% bracket):

• Total invested: ₹22,50,000
• Gross maturity amount: ₹39,80,000 (slightly higher rate)
• Tax on interest (₹17,30,000 interest × 30%): ₹5,19,000
• Actual wealth created: ₹34,61,000

PPF wins by ₹3,63,370 – despite having a slightly lower stated rate. The tax-free nature more than compensates for the lower return.

In an ELSS Fund (12% return, LTCG taxed at 12.5%):

• Gross maturity: approximately ₹68,00,000
• Tax on gains (₹45,50,000 gains, above ₹1.25 lakh threshold): approximately ₹5,66,000
• Actual wealth created: ₹62,34,000

ELSS wins on total returns because equity returns are significantly higher than PPF’s 7.1%. But PPF wins on certainty – ELSS returns are market-linked and could be much lower in any given period.

The smart move: Use BOTH. PPF for guaranteed, tax-free wealth building. ELSS or equity mutual funds for higher-growth wealth building. They serve different purposes in your portfolio.

Year-by-Year: How PPF Actually Grows

Let’s track a ₹1,50,000 annual contribution at 7.1% so you can see the compounding in action:

Year	Annual Contribution	Interest Earned That Year	Total Balance
1	₹1,50,000	₹10,650	₹1,60,650
3	₹1,50,000	₹23,500	₹5,14,000 (approx)
5	₹1,50,000	₹37,800	₹8,97,000 (approx)
10	₹1,50,000	₹77,400	₹21,58,000 (approx)
12	₹1,50,000	₹93,200	₹27,82,000 (approx)
15	₹1,50,000	₹1,13,500	₹38,24,370

Notice how the interest earned each year keeps growing – even though your contribution stays the same. In year 1, you earn ₹10,650 in interest. By year 15, you’re earning ₹1,13,500 in interest – more than 10x more. That’s compounding on your previous years’ interest, building on itself year after year.

Real Indian Scenarios

The Young Professional

Aisha, 25, opens a PPF account and puts in ₹1,50,000 every year (the maximum). She plans to keep it going for the full 15 years.

At 40 (maturity): ₹38,24,370 – completely tax-free.

She then extends for another 5 years, continuing to contribute ₹1,50,000 annually.

At 45: approximately ₹59,00,000 – still completely tax-free.

She extends again for 5 more years. At 50: approximately ₹90,00,000.

Aisha has built ₹90 lakhs in tax-free wealth by age 50 – from ₹37.5 lakhs of total contributions over 25 years. The remaining ₹52.5 lakhs is pure tax-free interest.

The Tax-Conscious Earner

Vikram is in the 30% tax bracket and earns ₹2 lakhs per month. Every rupee he puts into PPF saves him 30 paise in taxes (up to the ₹1.5 lakh annual limit under Section 80C).

By maxing out PPF at ₹1,50,000 per year, he saves ₹45,000 per year in taxes. Over 15 years, that’s ₹6,75,000 in tax savings alone – before even counting the tax-free interest.

The Late Starter

Mohan opens a PPF at age 45. He’s late, but not too late.

Contributing ₹1,50,000 per year for 15 years (until age 60):

• Total invested: ₹22,50,000
• Maturity amount: ₹38,24,370
• Tax-free interest: ₹15,74,370

₹38 lakhs of tax-free money at retirement age. It’s not as much as if he’d started at 25, but it’s still a meaningful, safe addition to his retirement corpus.

PPF Rules That Most People Don’t Know

Partial Withdrawal Is Possible

After 7 years (from year 8 onwards), you can withdraw up to 50% of your balance as of the end of the previous year. This is interest-free and tax-free. Useful if you need money for a specific goal but don’t want to close the account.

Loan Against PPF

From year 4 to year 6, you can take a loan against your PPF balance – up to 25% of the balance as of the end of the second year before the loan application. The interest rate is just 1% above the PPF rate. Much cheaper than a personal loan.

Joint Accounts Don’t Exist

PPF is strictly individual. You can’t open a joint PPF account. But you can open PPF accounts for your spouse and children (including minor children) – each gets their own ₹1.5 lakh annual limit.

Nomination Is Important

Always nominate someone on your PPF account. If something happens to you, the nominee can claim the balance without going through probate or legal hassle. Update nominations if your family situation changes.

Missing a Year Doesn’t Close the Account

If you don’t deposit the minimum ₹500 in any year, your account becomes “inactive” but doesn’t close. You can reactivate it by paying ₹500 plus a ₹50 penalty for each year it was inactive. But try not to let this happen – it disrupts compounding.

PPF vs Other Options – When Does PPF Win?

PPF Beats FDs When:

You’re in a tax bracket of 20% or above. The tax-free nature of PPF more than compensates for the slightly lower stated rate compared to some FDs.

PPF Loses to Equity Mutual Funds When:

Your time horizon is 10+ years and you can stomach market volatility. Equity funds have historically returned 12-15% versus PPF’s 7.1%. But PPF wins on certainty and zero tax.

PPF Is Perfect When:

• You want guaranteed, risk-free returns
• You want tax-free wealth building
• You want a forced saving mechanism (the 15-year lock-in prevents impulsive spending)
• You’re building a conservative retirement corpus alongside equity investments

Mistakes People Make with PPF

Opening It Too Late

PPF’s power comes from compounding over 15+ years. Opening it at 45 gives you decent returns. Opening it at 25 gives you life-changing returns. Every year you delay costs you significantly.

Not Maxing Out the ₹1.5 Lakh Limit

If you can afford it, always contribute the maximum ₹1.5 lakhs per year. The tax deduction alone saves you ₹30,000-45,000 depending on your bracket. And the tax-free compounding on the maximum amount is far more powerful than on a smaller amount.

Treating It as Your Only Investment

PPF at 7.1% won’t build serious wealth on its own. It’s a fantastic complement to equity investments – but not a replacement. Use PPF for the safe, tax-free portion of your portfolio. Use equity mutual funds for the growth portion.

Withdrawing Too Early

Yes, partial withdrawals are allowed after year 7. But every rupee you withdraw stops compounding. If you don’t genuinely need the money, leave it alone. The tax-free compounding is too valuable to interrupt.

Not Opening Accounts for Family Members

Each family member can have their own PPF account with their own ₹1.5 lakh limit. If you have a spouse and children, opening PPF accounts for all of them significantly multiplies the tax-free wealth building in your household.

Quick Tips for Getting the Most From PPF

Open it as early as possible – even with a small amount. You can start with just ₹500. The account is open, the clock is ticking, and you can increase contributions as your income grows.

Contribute before March 31 every year. Interest is calculated on the lowest balance between the 5th and last day of each month. If you contribute in April, you miss the interest for March. Contributing early in the financial year maximises your interest.

Put it on autopilot. Set up a standing instruction to transfer ₹12,500 per month (or whatever amount works for you) to your PPF account. This way you hit the ₹1.5 lakh target without thinking about it.

Combine with ELSS for maximum 80C benefit. Both PPF and ELSS qualify under Section 80C (total limit ₹1.5 lakhs). If you’re already maxing ELSS, you can still open PPF – the 80C limit is combined, but the PPF interest remains tax-free regardless.

Questions That Come Up A Lot

Can I open PPF online? Yes. Most major banks (SBI, HDFC, ICICI, etc.) allow you to open and manage PPF accounts entirely online. No need to visit a branch.

What happens after 15 years? You can either withdraw the entire amount (tax-free), or extend the account in 5-year blocks. If you extend, you can choose to continue contributing or just let the existing balance earn interest.

Is the 7.1% rate guaranteed for the full 15 years? No. The government reviews the PPF rate quarterly and can change it. Historically it’s stayed in the 7-8% range, but there’s no guarantee. For planning purposes, assume 7% to be conservative.

Can I have both PPF and EPF? Yes. EPF (Employee Provident Fund) is through your employer – it’s separate from PPF. Many Indians have both. They serve slightly different purposes but both contribute to retirement savings.

What if I need the money before 15 years? Partial withdrawals are allowed after year 7 (up to 50% of the balance). For emergencies before that, you can take a loan against the PPF balance from year 4. Complete premature closure is allowed only in very specific situations (like serious medical illness).

A Safe, Smart, Boring Investment That Actually Works

PPF won’t make you rich overnight. It won’t make for exciting dinner conversation. But over 15-25 years, it builds meaningful tax-free wealth with zero risk.

In a world full of “get rich quick” schemes and volatile market swings, there’s something genuinely valuable about an investment that just quietly does its job – year after year, tax-free, government-backed, and completely predictable.

Use this calculator to see exactly what your PPF will be worth. Then open an account if you haven’t already – or increase your contribution if you have.
