SIP vs NPS: Which Gives More Pension?

Both SIP and NPS are designed for retirement. But they work very differently. SIP lets you accumulate a large corpus and decide how to use it. NPS forces 40% into an annuity and gives you tax benefits today. Here is the real comparison with actual numbers.

Scenario	SIP (12% CAGR)	SIP Post-Tax	NPS (10% CAGR)	Take-Home Pension
₹5K/month × 20yr	₹49.9L	₹45.3L	₹37.9L	SIP: ₹18.9K/mo \| NPS: ₹11.0K/mo
₹10K/month × 20yr	₹99.9L	₹90.6L	₹75.8L	SIP: ₹37.8K/mo \| NPS: ₹22.0K/mo
₹15K/month × 25yr	₹2.85 Cr	₹2.55 Cr	₹2.18 Cr	SIP: ₹1.06L/mo \| NPS: ₹60.6K/mo
₹25K/month × 30yr	₹8.76 Cr	₹7.75 Cr	₹6.30 Cr	SIP: ₹3.23L/mo \| NPS: ₹1.82L/mo

NPS: The Good, the Bad, and the Annuity

NPS is structured for pension, not corpus accumulation. At 60, you must:

Take 60% tax-free: This portion is yours to use as you wish — no tax.
Buy annuity with 40%: This 40% must go into an annuity that pays you a monthly pension. Annuity rates are currently 5-7%, meaning ₹40L annuity corpus = ≈₹2.4L/year = ₹20K/month.
Annuity income is taxed at your slab rate. In the 30% bracket, you lose 30% to tax.

The effective tax on NPS withdrawal is higher than SIP's LTCG tax (12.5%) because annuity income is slab-rate taxable.

SIP: Full Control, Same Goal

With SIP, you can replicate NPS's pension feature using a Systematic Withdrawal Plan (SWP):

Build corpus: ₹10K/month SIP for 25 years = ₹1.7 Cr (post-LTCG)
Start SWP: Withdraw 5% of ₹1.7 Cr = ₹85,000/year = ≈₹7,000/month. But the SIP calculator shows the remaining corpus continues growing at 8-10%, so you can sustainably withdraw much more.
Typical sustainable withdrawal: 5-6% of initial corpus, adjusted for inflation. On ₹1.7 Cr: ≈₹70K/month + inflation adjustment.
Tax on SWP: Only the capital gains portion is taxed (12.5% LTCG), not the entire withdrawal like NPS annuity.

When NPS Makes Sense

Employer match: If your employer contributes 10-14% of basic to NPS, that's free money. Max this before SIP.
Old regime tax optimization: 80CCD(1B) gives ₹50K extra deduction. If you're in 30% bracket old regime, this saves ₹15,600/year in tax.
Ultra-low cost: NPS fund management fee is 0.09% vs mutual fund expense ratio of 0.2-1.5%. Over 25 years, this 0.1-1.4% difference compounds significantly.
Discipline: NPS's lock-in until 60 prevents premature withdrawals — helpful if you lack investment discipline.

When SIP Wins

Higher returns: 100% equity option in SIP vs NPS's max 75% equity cap.
Flexibility: No lock-in, no forced annuity, no age restrictions.
Better tax outcome: 12.5% LTCG vs NPS annuity taxed at slab rate.
Estate planning: SIP corpus goes fully to your nominee. NPS: nominee gets the remaining corpus after annuity purchase.
New regime: NPS's main tax benefit (80CCD deductions) doesn't apply in new regime. SIP is simply better.

The Verdict: Both, in the Right Order

Optimal retirement strategy:

First: Contribute enough to get full employer NPS match (free money).
Second: If on old regime, max out 80CCD(1B) ₹50K in NPS.
Third: Everything else goes into SIP (equity mutual funds).
At retirement: Use SIP corpus for flexible SWP. Use NPS 60% lump sum for big expenses and 40% annuity as base pension.

Use the SIP calculator to model your target corpus, then decide how much to allocate to NPS for the tax benefit and how much to SIP for growth.

Frequently Asked Questions

Which gives more monthly pension: SIP or NPS?

For the same investment, SIP generally gives higher total corpus, but NPS gives a structured pension. ₹10K/month for 25 years: SIP post-tax ≈₹1.7 Cr → withdraw all and use SWP of 5% = ₹70K/month pension. NPS ≈₹1.2 Cr (lower due to debt allocation) → 60% tax-free lump sum + 40% annuity gives ≈₹25K/month pension. SIP wins on flexibility and total return.

Can I use SIP instead of NPS for retirement?

Yes. Many investors use SIP as their primary retirement vehicle and skip NPS entirely. SIP offers: no lock-in (you can withdraw anytime), full control over allocation, higher historical returns, and simpler tax treatment. NPS advantages: extra ₹50K 80CCD(1B) deduction (old regime), employer contribution up to 14% of basic, ultra-low fund management fee of 0.09%.

Is NPS tax-free at withdrawal?

Partially. 60% of NPS corpus can be withdrawn tax-free at age 60. The remaining 40% must buy an annuity — annuity income is fully taxable as per your income tax slab. This is worse than SIP where LTCG above ₹1.25L is taxed at 12.5% (not your slab rate). For someone in 30% bracket, NPS annuity income loses 30% to tax.

What is the best strategy: NPS + SIP both?

Yes. Max out NPS employer contribution (free money from your employer), use the 80CCD(1B) ₹50K deduction if on old regime, then do the rest in SIP. Example: ₹50K/year in NPS for tax benefit + ₹1.1L/year in SIP for growth. This gives you the tax benefit AND the flexibility.

Does NPS outperform SIP in the new tax regime?

No. Under the new tax regime, NPS loses its main advantage: 80CCD(1) and 80CCD(1B) deductions are only available in the old regime. Only employer's 80CCD(2) contribution (up to 14% of basic) is available in both regimes. For new regime taxpayers, SIP is almost always better than NPS for wealth creation.
