SPUS vs VOO 2026: The Real Cost of Shariah Screening (2026)

The verdict, with the number that drives it

If you are a Muslim investor choosing between SPUS and VOO, the choice is not close: SPUS. VOO is the Vanguard S&P 500 ETF, and the S&P 500 is an unscreened index — it holds conventional banks, insurers, and companies carrying interest-bearing debt well above the Shariah ceiling. Owning VOO means owning a slice of riba-based finance, which fails the screen. SPUS — the SP Funds S&P 500 Sharia Industry Exclusions ETF — rebuilds that same large-cap US exposure with the non-compliant names removed.

For everyone else, the calculus flips entirely. VOO charges 0.03%. SPUS charges 0.45%. That 0.42-percentage-point gap is the entire story for a cost-focused investor with no compliance constraint: roughly $420 a year on a $100,000 balance, and it compounds. So the honest framing is not “which fund is better” — it is “does Shariah compliance matter to you, and is it worth 0.42% a year?”

Head-to-head: the numbers that actually differ

Figures: SP Funds (SPUS factsheet, verified 2026-06-23) and Vanguard (VOO profile). SPUS holdings and yield reprice — re-check the issuer factsheet before you rely on a specific number.

Why VOO fails the Shariah screen

VOO is a wrapper around the S&P 500. It owns whatever the index owns, in the same weights, with no religious or ethical filter. To judge it against Shariah, you run the AAOIFI Standard 21 two-stage screen — the standard most US halal funds and apps (Musaffa, Zoya, Wahed) anchor to.

Stage 1 — business activity

A company fails if more than 5% of its revenue comes from prohibited activities: conventional interest-based finance and insurance, alcohol, tobacco, gambling, pork, weapons, adult entertainment, or conventional media. The S&P 500 is roughly 13% financials — JPMorgan Chase, Bank of America, Wells Fargo, and the major insurers. Every one of those is a conventional, interest-based business. VOO holds all of them.

Stage 2 — financial ratios

Even among non-financial companies, AAOIFI sets hard limits:

• Interest-bearing debt must be at or below 30% of market cap.
• Cash plus interest-bearing securities at or below 30%.
• Impermissible (interest) income at or below 5% of total income.

Plenty of S&P 500 industrials, utilities, and consumer names carry debt loads that blow past 30% of market cap. VOO does not check — it holds them anyway. SPUS applies both stages and drops every failing name, which is why it lands at ~200 holdings instead of ~505. The math is simple: a fund with zero screening cannot be compliant, no matter how good its diversification or how low its fee.

What SPUS actually holds

SPUS is not some obscure, off-the-beaten-path fund. Its top holdings are the same mega-cap names anchoring VOO: NVIDIA (~13.3%), Apple (~11.5%), Microsoft (~7.2%), Alphabet (~5.4%), and Broadcom (~4.9%) as of the issuer’s factsheet. If you own VOO today, the largest positions you would carry over to SPUS are nearly identical at the very top.

The differences show up below the surface:

• No financials. The single biggest structural difference. VOO’s ~13% bank-and-insurer sleeve is gone in SPUS.
• Heavier tech tilt. Removing financials and over-leveraged names pushes SPUS toward technology and healthcare, which raises its concentration. Top-5 holdings are ~42% of SPUS versus ~30% of VOO.
• Fewer names. ~200 vs ~505. You still get broad large-cap exposure, but with a real concentration in the biggest tech companies.

That concentration cuts both ways. In a year mega-cap tech leads, SPUS can outrun VOO. In a year financials and value lead, SPUS lags. Compliance changes your sector exposure, not just your fee.

This is the part most investors underestimate. They treat SPUS as “VOO, but halal” — a clean one-for-one swap with a slightly higher fee. It is not. By cutting roughly 13% of the index in financials and trimming over-leveraged names elsewhere, SPUS becomes a meaningfully different bet on the US market: more growth, more technology, less value, and less of the dividend-heavy sectors. When you switch from VOO to SPUS you are not just paying for a screen; you are taking a position that the screened-out sectors will not lead. Most years that is fine. In a value-led or financials-led market it can cost you more than the 0.42% fee gap ever will — and that tracking difference, not the expense ratio, is the real variable to watch.

The real cost of screening, in dollars

“0.45% versus 0.03%” is abstract. Here is what the 0.42% gap costs over time on a $100,000 position, assuming both funds return 7% a year before fees:

These are illustrative, rounded figures — actual fee drag depends on your real returns and contributions. The point stands: the lifetime cost of Shariah screening on a six-figure balance is measured in five figures. For a Muslim investor, that cost buys compliance, which is not optional. For a non-Muslim investor with no compliance need, paying it for slightly different sector exposure makes little sense — VOO is the better default.

What most people miss: the yield and purification gap

The fee gets all the attention, but two quieter differences matter.

Yield. SPUS’s 30-day SEC yield is about 0.39% versus VOO’s ~1.00%. That is not a fluke — it is structural. SPUS screens out high-dividend financials and over-leveraged utilities, and tilts toward growth-oriented tech that reinvests rather than pays out. If you are building a portfolio that leans on dividend income, SPUS delivers materially less of it than VOO. For an accumulator reinvesting everything, the gap matters less; for a retiree drawing income, it matters more.

Purification. Even a compliant fund like SPUS holds companies that earn a small slice of incidental interest income (a tech company parking cash in an interest-bearing account, for example). AAOIFI requires you to purify that portion — calculate the share of your dividend attributable to impermissible income and donate it to charity (it is not tax-deductible). SP Funds publishes a quarterly purification calculator for SPUS so you do not have to estimate it. VOO has no such mechanism because it makes no compliance claim. This is a real, recurring task SPUS owners take on that VOO owners never think about.

SPUS vs HLAL: if you’re already committed to halal

If you have decided you need a Shariah-compliant US large-cap fund, the more useful comparison is not SPUS vs VOO — it is SPUS vs HLAL, the Wahed FTSE USA Shariah ETF.

SPUS is cheaper by 0.05%, larger, and more liquid. HLAL uses FTSE’s methodology and is screened by Yasaar Ltd. For most US Muslim investors the two are close substitutes; SPUS edges it on fee and assets. The deeper breakdown lives in the dedicated SPUS vs HLAL guide linked above.

Which wins for whom

1. Muslim investor, any account type: SPUS. VOO is not an option — it holds the financial sector and unscreened debt. SPUS is the closest compliant proxy for the S&P 500, and the 0.45% fee is the price of compliance.
2. Non-Muslim, cost-focused: VOO. At 0.03% it is one of the cheapest funds in existence, more diversified (~505 vs ~200), and yields more (~1.00% vs ~0.39%). There is no reason to pay 15× the fee for a compliance feature you do not need.
3. Retiree needing income: VOO yields meaningfully more. A halal investor in this seat should pair SPUS with a sukuk fund like SPSK (4.41% 30-day SEC yield) rather than reaching for yield inside SPUS.
4. Accumulator with a long runway: Either works on its own terms — SPUS if compliance matters, VOO if it does not. The fee drag compounds, so know which constraint you are actually optimizing for.

The decision lever

Strip away the comparison tables and one question decides this: does Shariah compliance bind your portfolio? If yes, the SPUS-vs-VOO debate is already settled — VOO is off the table and your real choice is SPUS vs HLAL. If no, VOO wins on cost, diversification, and yield, and there is no case for paying an extra 0.42% a year. Everything else — the concentration, the lower yield, the purification step — is downstream of that single binding constraint.

This is Shariah-compliance mechanics applied to public fund data, not a fatwa. Holdings and screens change — verify SPUS’s current factsheet via SP Funds, cross-check a name on Musaffa or Zoya, and consult a qualified scholar for a binding ruling on your specific situation.
