# Low-Cost US Broad-Market ETFs
**Query:** Low-cost US-listed ETFs tracking the S&P 500 or total US market, compared by expense ratio
**Data as of:** 2026-10-02

Broad US index ETFs (S&P 500 or total US market) with expense ratios at or below 0.20%, sorted cheapest first. The core S&P 500 and total-market trackers cluster tightly at 0.02-0.03% and deliver near-identical returns, so cost and scale are the main differentiators.

### Low-Cost Broad US Market & S&P 500 ETFs

| Symbol | Security Name | Tracking Approach | Expense Ratio | AUM ($B) | 1M Return | 6M Return | 1Y Return | Top Holdings | Comments |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| BBUS | JPMorgan BetaBuilders U.S. Equity ETF | US large/mid-cap (top 85%) | 0.02% | 8.38 | 0.97% | 18.20% | 15.98% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Cheapest broad-market tracker on the list and the pure fee-leader — an S&P-linked, free-float market-cap index targeting the top 85% of US market cap. The trade-off is scale: it is far smaller than the Vanguard/iShares giants, so spreads and depth are thinner, which matters most for large or frequent trades. |
| VTI | Vanguard Total Stock Market ETF | Total US market (all-cap) | 0.03% | 2,309 | 0.55% | 17.38% | 16.09% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | The definitive single-ticker 'own the whole US market' fund (CRSP Total Market, ~100% of investable US equity), with unmatched scale and tiny cash drag. Its added small-cap tail is the key structural difference vs an S&P 500 fund — a modest diversifier, though large-caps still dominate returns. |
| VOO | Vanguard S&P 500 ETF | S&P 500 (large-cap) | 0.03% | 1,702 | 0.85% | 17.98% | 16.45% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Vanguard's S&P 500 flagship: essentially the same portfolio as IVV and SPY but with the lowest-cost, most tax-efficient structure among the three giants. For long-term holders it is the default core large-cap sleeve; tracking is near perfect. |
| IVV | iShares Core S&P 500 ETF | S&P 500 (large-cap) | 0.03% | 854.917 | 0.85% | 17.98% | 16.43% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | iShares' equivalent of the S&P 500 at the same rock-bottom fee, with deep liquidity that makes it a favorite intraday trading vehicle as well as a core holding. Functionally interchangeable with VOO — choose on platform/commission, not cost. |
| ITOT | iShares Core S&P Total U.S. Stock Market ETF | Total US market (all-cap) | 0.03% | 93.4203 | 0.60% | 17.51% | 16.15% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Total-US-market exposure (all NYSE/Nasdaq/Cboe listings) at S&P-500 pricing. Its all-cap index is broader than an S&P 500 fund and slightly more diversified, at the cost of a modest small-cap drag in mega-cap-led rallies. |
| VV | Vanguard Large-Cap ETF | US large-cap (top ~85% CRSP) | 0.03% | 74.7407 | 1.03% | 18.41% | 16.15% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Tracks the CRSP US Large Cap index (top ~85% of investable cap) — a wider definition than the S&P 500 that sweeps in more mid-cap names and recently-promoted large caps, giving a slightly less concentrated, less committee-driven large-cap blend. |
| SCHX | Schwab U.S. Large-Cap ETF | US large-cap (DJ 1-750) | 0.03% | 72.6327 | 0.87% | 17.87% | 15.96% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Dow Jones US Large-Cap Total Stock Market index (roughly the top 750 names) — a broader large-cap proxy than the S&P 500 with less index-committee turnover. Funded by Schwab's low-cost platform, a solid core holding for cost-sensitive buy-and-hold investors. |
| SCHB | Schwab U.S. Broad Market ETF | Total US market (all-cap) | 0.03% | 43.3097 | 0.61% | 17.52% | 16.06% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Schwab's total-market entrant (top 2,500 names). Same headline fee as the giants; the gap is AUM and trading depth, not construction. Good for small recurring investments where commission-free trading dominates total cost. |
| SPTM | State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF | S&P 1500 Composite (all-cap) | 0.03% | 13.6403 | 0.61% | 17.25% | 16.24% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | S&P 1500 Composite — S&P 500 plus MidCap 400 and SmallCap 600 — is the widest S&P-family coverage here, blending large-cap leadership with a genuine mid/small tail. A neat one-fund all-cap core if you want indices from a single provider. |
| SCHK | Schwab 1000 Index ETF | US large-cap (Schwab 1000) | 0.03% | 5.6918 | 0.68% | 17.74% | 16.12% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Schwab 1000 Index (largest 1,000 US names) sits between an S&P 500 and a total-market fund — more diversified than the S&P 500 but still overwhelmingly large-cap. Small AUM means wider spreads; best used as a low-cost core with periodic, not tactical, flow. |
| PBUS | Invesco MSCI USA ETF | Total US, large/mid (MSCI USA) | 0.04% | 11.4104 | 0.91% | 18.05% | 15.98% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | MSCI USA large/mid-cap exposure — a broader large/mid blend than the S&P 500, with MSCI's float methodology rather than S&P's committee screens. Slightly higher fee than the giants, so it competes on construction rather than price. |
| VTHR | Vanguard Russell 3000 ETF | Total US market (all-cap) | 0.06% | 6.1161 | 0.54% | 17.28% | 15.87% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Russell 3000 (top 3,000 names, ~98% of US market) is the classic broad-market benchmark, and this is the ETF share class of Vanguard's index-tracking approach. Larger AUM alternative (IWV) tracks the same index but costs more. |
| DFUS | Dimensional U.S. Equity Market ETF | Total US market (all-cap) | 0.09% | 20.8757 | 0.83% | 17.83% | 16.51% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Dimensional's index-tracking all-cap fund sits inside an active-manager family known for factor tilts elsewhere, but this vehicle stays market-like. Its higher fee versus the fee-leaders is the cost of the Dimensional platform and its distribution model. |
| SPY | State Street SPDR S&P 500 ETF Trust | S&P 500 (large-cap) | 0.09% | 783.7964 | 0.84% | 17.95% | 16.38% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | The original and most-traded S&P 500 vehicle — an unit investment trust, so dividends sit in cash until payout and cannot be internally reinvested, creating a small structural cash drag. The price of that structure and its unmatched liquidity is roughly triple the fee of VOO/IVV. |
| IWB | iShares Russell 1000 ETF | US large-cap (Russell 1000) | 0.15% | 48.871 | 0.67% | 17.30% | 15.67% | NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO, GOOG, META, MU, TSLA | Russell 1000 large-cap exposure, fully market-cap weighted, but priced at the high end of this group — hard to justify over cheaper large-cap options unless you specifically want the Russell 1000 construction and its deeper liquidity in size. |

### Takeaway

## The cost floor is real, and it has stopped falling

At the sharp end of broad US index ETFs, the fee race is effectively over: **JPMorgan's BBUS at 0.02%** and a wall of 0.03% funds (**VTI, VOO, IVV, ITOT, VV, SCHX, SCHB, SPTM, SCHK**) now sit within a single basis point of each other. For a long-term core holding, the difference between 0.02% and 0.03% is roughly $1 per $10,000 invested per year — noise. The decisions that actually matter are **index construction**, **scale**, and **structure**.

### S&P 500 vs total US market: a small but persistent spread
- **S&P 500 funds (SPY, IVV, VOO)** hold ~500 US mega/large caps chosen by S&P's committee. They are the most concentrated, most mega-cap-heavy version of the US market.
- **Total-market funds (VTI, ITOT, SCHB, VTHR)** hold essentially the entire investable US market — thousands of names. The extra small/mid-cap tail is a genuine diversifier, but with the index still ~80%+ large-cap, the return difference versus an S&P 500 fund is usually under a percentage point either way.
- **Hybrids (VV, SCHX, SCHK, SPTM, PBUS, BBUS, IWB)** track wide large-cap or all-cap indices (CRSP US Large Cap, Dow Jones 1-750, S&P 1500, Russell 1000/3000). They land between the two poles and often tilt a touch less concentrated than the S&P 500.

### Scale and liquidity
AUM here spans three orders of magnitude — from ~$5.7B (SCHK) to over $2.3T (VTI), with VOO and IVV each in the high hundreds of billions. Bigger funds generally mean tighter spreads, deeper secondary liquidity, and lower operational drag, which matters most for large or frequent trades. Small funds like SCHK, VTHR and SPTM are perfectly fine for periodic dollar-cost-averaging but can cost more than the headline fee in spread if traded aggressively.

### Structure quirks
- **SPY** is the oldest and most liquid, but it is a unit investment trust: dividends accumulate in cash and cannot be reinvested between payouts, adding a small drag — one reason it charges ~0.0945%, more than triple the 0.03% leaders. Its edge is intraday liquidity, not cost.
- **VOO/IVV** use standard ETF structures with the same index as SPY at one-third the cost, making them the better buy-and-hold choices.
- **DFUS** (0.09%) and **IWB** (0.15%) are the priciest here and only make sense if you specifically want Dimensional's platform or the Russell 1000.

**Bottom line:** for a cost-first core, VOO (S&P 500) or VTI (total market) at 0.03% remain the benchmark choices; BBUS undercuts them by a basis point but at a fraction of the scale. SPY and IWB are the expensive legacies in an otherwise commoditized lineup.
