NSC vs PPF: How ₹1.5L a Year Grows Over 5 Years vs 15

If you're the kind of saver who breaks into a cold sweat when the Sensex drops 800 points in a day, you've probably parked your money in something "safe" — a bank FD, maybe a recurring deposit, and if you've done your homework, either the National Savings Certificate (NSC) or the Public Provident Fund (PPF). Both are backed by the Government of India. Both give you Section 80C deductions. And both feel like the financial equivalent of a warm blanket.

But here's the part most people get wrong: they treat NSC and PPF as interchangeable. They aren't. One locks your money for 5 years and taxes the interest you earn. The other locks it for 15 years but hands you every rupee completely tax-free at maturity. Invest the same ₹1.5 lakh a year in each, and after a decade and a half you could be looking at a difference of several lakhs — not because one "beats" the other on paper, but because of how compounding and taxation quietly stack the deck.

In this NSC vs PPF comparison, I'll walk you through the exact maturity maths for a ₹1.5 lakh annual investment — over 5 years for NSC and 15 years for PPF — factor in the small savings rate reset expected in the Oct–Dec 2026 quarter, and show you which one actually deserves a place in your portfolio. No jargon dumps. Just the numbers, the tax logic, and a clear verdict.

Key Takeaways

• PPF interest is fully tax-free (EEE); NSC interest is taxable — this single fact changes your effective return dramatically, especially in the 30% tax bracket.
• NSC has a 5-year lock-in; PPF locks for 15 years but allows partial withdrawals from year 7 and loans from year 3.
• Both currently pay well: NSC ~7.7% (compounded annually), PPF ~7.1% — but the post-tax winner is almost always PPF.
• NSC interest (except the final year) qualifies for a fresh 80C deduction because it's deemed reinvested — a benefit many savers miss.
• The Oct–Dec 2026 rate reset could nudge these rates down if the RBI continues easing — lock in NSC certificates before a downward revision if you're going that route.
• For a 15-year goal, PPF's tax-free compounding is hard to beat for a risk-averse saver; NSC suits shorter 5-year horizons.

What exactly are NSC and PPF — and why do savers confuse them?

Both are part of India's small savings schemes, sold through post offices and most public and private sector banks. The government resets their interest rates every quarter. That's where the similarity ends.

The National Savings Certificate (NSC) is a fixed-term instrument with a 5-year lock-in. You buy a certificate for a lump sum — say ₹1.5 lakh — and it earns a fixed rate (currently around 7.7% per annum, compounded annually) for those 5 years. The interest accrues but is paid out only at maturity. There's no upper limit on how much you can invest, though only ₹1.5 lakh qualifies for 80C.

The Public Provident Fund (PPF) is a 15-year scheme (extendable in blocks of 5 years). It currently pays around 7.1% per annum, compounded annually. You can invest between ₹500 and ₹1.5 lakh per financial year. The big draw: PPF enjoys EEE status — Exempt on contribution, Exempt on interest, Exempt on maturity. Not a single rupee is taxed.

The tax difference that changes everything

NSC is technically EET-ish in practice: your investment gets 80C, but the interest is taxable in the year it accrues (though for the first four years it's deemed reinvested and qualifies for a fresh 80C deduction). At maturity, the full interest is taxed as "income from other sources" at your slab rate.

If you're in the 30% bracket, a headline 7.7% NSC return quietly becomes roughly 5.4% post-tax. PPF's 7.1% stays 7.1% — because it's tax-free. Suddenly the "lower" rate looks a lot better.

NSC vs PPF comparison: ₹1.5 lakh a year, the exact maturity maths

Let's do real numbers. I'll use current indicative rates and hold them constant for clarity, then adjust for the 2026 reset scenario afterward.

Scenario A: NSC — ₹1.5 lakh invested once, matured after 5 years

NSC compounds annually. A single ₹1,50,000 certificate at 7.7% for 5 years:

• Formula: Maturity = P × (1 + r)^n = 1,50,000 × (1.077)^5
• (1.077)^5 ≈ 1.4490
• Maturity ≈ ₹2,17,350
• Interest earned ≈ ₹67,350

Now the tax bite. If Meera is in the 30% slab, her interest of ₹67,350 is taxable. Roughly ₹21,000 goes to tax (plus cess), leaving her net gain around ₹46,350. Her effective post-tax corpus: about ₹1,96,350.

But suppose she buys a fresh ₹1.5 lakh NSC every year for 5 years (a common "ladder" approach). By year 5 she'd have five certificates maturing in sequence, having invested ₹7.5 lakh total. The combined maturity value (pre-tax) works out to roughly ₹9.05 lakh — but each year's interest is taxable along the way.

Scenario B: PPF — ₹1.5 lakh every year for 15 years

This is where compounding earns its reputation. Assume Meera deposits ₹1,50,000 at the start of each financial year (before 5th April to maximise interest) at 7.1%, for 15 years.

The maturity value of an annual deposit annuity:

• Formula (deposit at start of year): M = P × [((1+r)^n − 1) / r] × (1+r)
• P = 1,50,000; r = 0.071; n = 15
• (1.071)^15 ≈ 2.8065
• [(2.8065 − 1) / 0.071] ≈ 25.443
• × (1.071) ≈ 27.25
• Maturity ≈ 1,50,000 × 27.25 ≈ ₹40,87,000

Total invested: ₹22.5 lakh (₹1.5L × 15). Interest earned: roughly ₹18.37 lakh — and every single rupee of it is tax-free. In the 30% bracket, replicating this in a taxable instrument would need a pre-tax return of over 10% just to match. That's the quiet magic of EEE.

How does the Oct–Dec 2026 rate reset affect the numbers?

Small savings rates are notionally linked to government bond yields and reviewed quarterly. With the RBI in an easing cycle through 2025-26, there's a real possibility that the Oct–Dec 2026 quarter sees a modest downward revision — say NSC to ~7.4% and PPF to ~6.9%.

Here's what that does to a fresh 15-year PPF at 6.9% instead of 7.1%:

• (1.069)^15 ≈ 2.727
• [(2.727 − 1) / 0.069] ≈ 25.03 × 1.069 ≈ 26.76
• Maturity ≈ 1,50,000 × 26.76 ≈ ₹40.14 lakh

A 0.2% rate cut trims roughly ₹73,000 off a 15-year PPF corpus. For NSC at 7.4% vs 7.7%, a single ₹1.5L certificate matures at about ₹2.14 lakh instead of ₹2.17 lakh — a smaller absolute difference because of the shorter term.

Pro tip: PPF interest is credited on your balance at the rate prevailing each quarter — so a future rate cut affects all your accumulated corpus, not just new deposits. NSC, by contrast, locks the rate at the time of purchase for the full 5 years. If you believe rates are heading down and NSC suits your goal, buying before the Oct–Dec 2026 reset locks in the higher 7.7%. That's a rare case where timing genuinely matters.

Side-by-side: NSC vs PPF vs a taxable FD on ₹1.5 lakh/year

To put it all in context, here's how the same annual investment stacks up. I've assumed a 5-year comparison for fairness on lock-in, and a 30% tax slab.

Criteria	NSC	PPF	5-Year Tax-Saver FD
Current rate (indicative)	~7.7%	~7.1%	~7.0%
Lock-in	5 years	15 years	5 years
80C deduction	Yes (₹1.5L)	Yes (₹1.5L)	Yes (₹1.5L)
Interest taxed?	Yes, at slab	No (tax-free)	Yes, at slab
Effective post-tax return (30% slab)	~5.4%	~7.1%	~4.9%
Partial withdrawal	No	From year 7	No
Best for	5-year goals, laddering	Long-term, tax-free wealth	Convenience via bank

The verdict is clear: for anyone in the 20% or 30% tax bracket with a long horizon, PPF's tax-free status makes it the superior wealth-builder, even at a lower headline rate. NSC shines only when your goal is genuinely 5 years away and you want a fixed, locked rate. You can sanity-check FD outcomes on our FD Calculator and compare against a recurring deposit using the RD Calculator.

How to open NSC and PPF accounts: a step-by-step walkthrough

Opening a PPF account

1. Choose a provider — SBI, HDFC, ICICI, or your nearest post office all offer PPF. Banks with net-banking integration make annual deposits effortless.
2. Fill Form A (account opening) with your PAN, Aadhaar, address proof and a passport photo.
3. Make an initial deposit (minimum ₹500). You can deposit up to ₹1.5 lakh per FY in lump sum or up to 12 instalments.
4. Deposit before the 5th of the month — PPF interest is calculated on the lowest balance between the 5th and month-end. Depositing your full ₹1.5L before 5th April each year maximises interest.
5. Set a standing instruction or a recurring reminder so you never miss a year (a lapsed account needs a ₹50 penalty + minimum deposit to revive).

Buying NSC

1. Visit any post office or a bank authorised to sell NSC.
2. Submit KYC (PAN mandatory for investments above ₹50,000), Aadhaar and a photo.
3. Pay the amount by cheque or cash (electronic certificates are now standard, held in your post office savings account).
4. Retain the certificate details — you'll need them at maturity in 5 years.
5. Every year, claim the accrued NSC interest as a fresh 80C deduction (except the final year's interest), and also declare it as taxable income. This nets off nicely if you're within the ₹1.5L 80C limit.

Common mistake: Savers forget to declare NSC accrued interest annually and then get hit with a large taxable amount all at once in year 5 — pushing them into a higher slab. Declare it year by year and claim the reinvestment 80C benefit. It's cleaner and tax-efficient.

Which one should you actually choose?

Match the instrument to your goal, not the other way round:

• Goal 5 years away (child's school admission, car down-payment, a planned home renovation): NSC or a laddered set of NSCs works well. Consider our FD laddering guide — the same logic applies to NSC certificates.
• Goal 10–15+ years away (retirement corpus, child's higher education): PPF, no contest. The tax-free compounding compounds harder every passing year.
• You've maxed 80C already: NSC still works as a safe parking spot (though interest is taxed); PPF's ₹1.5L cap means you can't over-contribute anyway.
• You want equity-linked growth too: don't put everything in fixed-income. Read why staying invested in SIPs beats panic and model a blended plan with our SIP Calculator.

Personally, for most salaried readers I recommend PPF as the backbone of the fixed-income allocation, topped up with NSC only when a specific 5-year goal exists. If you're a government employee weighing pension options too, the UPS vs NPS comparison for 2026 is worth a read alongside this.

Don't forget inflation and the bigger picture

A 7.1% tax-free return sounds great — until you remember inflation. If CPI averages 5%, your real return is closer to 2%. That's still positive and safe, but it won't build serious wealth alone. Run your maturity figures through our Inflation Calculator to see the purchasing power of that ₹40 lakh in 15 years.

This is why the risk-averse saver's ideal portfolio isn't 100% PPF and NSC. It's a core of these safe instruments for capital protection, plus a growth sleeve of equity SIPs for beating inflation. Use the Goal Planner Calculator to figure out how much of each you need for a target corpus. And to check whether your overall tax planning is optimal under the new vs old regime, our Income Tax Calculator is a quick way to decide if 80C deductions even help you (under the default new regime, 80C is unavailable — a crucial point covered below).

Frequently Asked Questions

Is NSC or PPF better for tax saving in FY 2025-26?

Both offer ₹1.5 lakh under Section 80C, but only under the old tax regime. Under the new (default) regime, neither gives a deduction. If you still opt for the old regime and have a long horizon, PPF is better because its interest is fully tax-free, whereas NSC interest is taxed at your slab.

Can I invest more than ₹1.5 lakh in NSC?

Yes — NSC has no upper investment limit, but only ₹1.5 lakh qualifies for the 80C deduction in a financial year. PPF, by contrast, has a hard cap of ₹1.5 lakh per FY; deposits beyond that earn no interest and are refunded.

What happens to PPF if I miss a year's deposit?

The account becomes dormant. To revive it, you pay a ₹50 penalty for each missed year plus the ₹500 minimum deposit for those years. The balance keeps earning interest even while dormant, so it's not the end of the world — but avoid lapses to keep 80C eligibility intact.

Is NSC interest really eligible for a fresh 80C deduction?

Yes. Because NSC interest is deemed reinvested for the first four years, you can claim that accrued interest as a fresh 80C deduction (within the overall ₹1.5 lakh limit) in each of those years. Only the fifth (final) year's interest doesn't get reinvested and is simply taxable.

Can I withdraw from PPF before 15 years?

Partial withdrawals are allowed from the 7th financial year, up to 50% of the balance at the end of the 4th preceding year. Loans against PPF are available between years 3 and 6. Premature closure is permitted only in specific cases like serious illness or higher education, with a 1% interest penalty.

Will the Oct–Dec 2026 rate reset affect my existing NSC?

No. NSC locks the interest rate at the time of purchase for the entire 5-year term. Rate resets only affect certificates bought after the revision date. PPF, however, applies the revised rate to your entire balance from the new quarter onwards.

Final verdict on the NSC vs PPF comparison

Strip away the marketing and the numbers tell a simple story. For a risk-averse saver putting in ₹1.5 lakh a year, this NSC vs PPF comparison comes down to two questions: How long is your goal? and What's your tax bracket?

If your money must be available in 5 years, NSC's fixed, locked rate and shorter horizon make sense — buy it before any downward rate reset. But if you're building a corpus for 15 years or more, PPF's tax-free compounding turns ₹22.5 lakh of deposits into roughly ₹40 lakh of tax-free wealth. In the 30% bracket, nothing else in the "safe" category comes close on a post-tax basis.

My advice: make PPF the foundation of your fixed-income allocation, use NSC surgically for genuine 5-year goals, and don't let either replace an equity SIP for beating inflation. Run your exact figures through our PPF Calculator and Goal Planner before the 2026 reset, and if you'd like to understand more about who we are or send a question, visit our about page or get in touch.
