VT holds the whole world’s stock market in one fund. VTI plus VXUS rebuilds the same thing from two. Here is what the split really changes: cost, control over how much you keep at home, rebalancing, and the foreign tax credit in a taxable account.

They hold nearly the same stocks, so the choice is about convenience against control. VT (Vanguard Total World Stock ETF) tracks the FTSE Global All Cap Index: large, mid and small companies in developed and emerging markets, the US included. VTI covers the US market and VXUS (Vanguard Total International Stock ETF) covers everything outside it, so the two together rebuild VT in whatever proportions you choose.
Scope: US investors using these funds for the stock part of a retirement portfolio. Bonds, target-date funds and other issuers’ versions are covered elsewhere (three-fund portfolio, target-date fund check). Education, not tax or investment advice.
| Situation | VT tends to fit | VTI + VXUS tends to fit |
|---|---|---|
| All stock money is in an IRA, Roth or 401(k) | Yes: one fund, no rebalancing | Fine, but the tax edge disappears |
| Meaningful stock holdings in a taxable account | Loses the foreign tax credit | Yes: VXUS can pass the credit through |
| You want a fixed split, such as 70% US / 30% international | No: VT follows market weights | Yes: you set the weights |
| You tend to tinker when one region lags | Yes: nothing to adjust | Risk of chasing the recent winner |
| You want the lowest possible fee | Slightly higher (0.06%) | About 0.04% at VT’s weights |

The last decade favored US stocks, which is why VTI leads on 5 and 10 years. The past year went the other way: VXUS returned 18.49% against 15.33% for VTI, and 32.4% against 17.1% in calendar 2025 (Exent market data). In 2024 it was the reverse: 5.1% for VXUS against 23.8% for VTI. That is the diversification you buy: international stocks do not always zig when US stocks zag, but they often move by different amounts. Long-run context is in US vs international returns and international ETFs for retirement.
62.4% on Sep 30, 2026, followed by Japan at 6.0%, Taiwan 3.5%, the United Kingdom 3.1% and Canada 3.0% (VT fact sheet). That share is not fixed: VT weights countries by market value, so the US share rises when US stocks outperform and falls when they lag. With VTI and VXUS you decide the split yourself.
For reference, Vanguard’s own target-date funds hold 60% US and 40% international stocks, and Vanguard writes that 30% to 40% in international stocks has provided more than 95% of the benefit of full market-cap diversification (Vanguard). An investor who wants, say, 25% abroad can only get there with two funds. See international diversification.
In a taxable account it works with VXUS but not with VT. Foreign governments withhold tax on dividends paid to US funds. A fund can pass that tax through to you as a credit only if more than 50% of its assets at year end are stock or securities of foreign corporations (26 U.S.C. §853(a)). VXUS is entirely foreign; VT is about 38% foreign. Vanguard’s 2025 foreign tax credit table lists VXUS, with foreign tax paid equal to 7.11% of its ordinary dividends, and does not list VT (Vanguard 2025 foreign tax credit table).
The IRS lets you take passed-through foreign taxes as a credit or an itemized deduction, reported on your Form 1099-DIV, and the credit is usually the better choice; small amounts, up to $300 ($600 on a joint return), can generally be claimed without Form 1116 (IRS Publication 514). Inside an IRA or 401(k) there is no credit: the foreign tax still reduces the dividend, but nothing appears on your return to offset (Morningstar).
Exent calculation, illustrative: $300,000 of stocks in a taxable brokerage account, held either as VT or as VTI and VXUS at VT’s own weights. Inputs: expense ratios from Vanguard, VXUS’s trailing 12-month distribution yield of 2.34% (Exent market data, Sep 30, 2026) and Vanguard’s 2025 foreign-tax rate of 7.11% applied as if it repeated.
| All in VT | 62.4% VTI + 37.6% VXUS | |
|---|---|---|
| Amounts | $300,000 VT | $187,200 VTI + $112,800 VXUS |
| Yearly fund expenses | $300,000 × 0.06% = $180 | $187,200 × 0.03% + $112,800 × 0.05% = $56.16 + $56.40 ≈ $113 |
| VXUS dividends | — | $112,800 × 2.34% ≈ $2,640 |
| Foreign tax credit passed through | $0 (VT not eligible in 2025) | $2,640 × 7.11% ≈ $188 |
| Yearly advantage of the split | — | ($180 − $113) + $188 ≈ $255 |
About $255 a year on $300,000, or roughly 0.085% of the stock holding, before counting the time spent rebalancing. Two caveats keep it in proportion: the foreign tax passed through is also added to your dividend income (a gross-up), so the net benefit is a bit smaller than the credit, and the credit only returns tax that was already withheld abroad. The same $300,000 held in an IRA would keep only the $67 fee difference.
Yes, and that is the real cost of two funds. A fixed split drifts as markets move. Exent calculation, illustrative: 60% VTI and 40% VXUS bought at the end of September 2016 and never touched, growing at the funds’ 10-year NAV returns of 14.70% and 9.20% a year (Vanguard, Sep 30, 2026), ends at about 71% US and 29% international ten years later (60 × 1.147^10 ≈ 237 against 40 × 1.092^10 ≈ 97). Bringing it back means selling the winner, which in a taxable account can realize gains; directing new money and dividends to the lagging fund avoids most of that. VT does this inside the fund at no tax cost to you. Methods are in how to rebalance.
Behavior matters as much as arithmetic. Morningstar’s 2026 Mind the Gap study found the average fund dollar earned 1.2 percentage points a year less than the funds themselves over ten years, with wider gaps in more volatile funds (Morningstar). A second fund is a second thing to sell at the wrong time.
| Fund | Pros | Cons |
|---|---|---|
| VT | The whole world in one fund; about 10,000 stocks; market weights rebalance themselves; nothing to adjust in a downturn. | Higher fee (0.06%); no foreign tax credit pass-through; you cannot change the 62/38 split; US share drifts with markets. |
| VTI | Lowest fee (0.03%); about 100% of investable US companies; very tax-efficient in taxable accounts. | US only: needs an international fund for global diversification; trailing 1-year returns lagged VXUS. |
| VXUS | Low fee (0.05%); developed and emerging markets, large to small; passes through a foreign tax credit in taxable accounts. | Higher dividends create more taxable income; deepest 5-year drop of the three (−28.9%); currency moves add volatility. |
Expense ratios and holdings from the issuers (holdings as of Sep 30–Oct 23, 2026):
| ETF | Role | Expense ratio | Holdings | Note |
|---|---|---|---|---|
| ACWI (iShares) | Global, one fund | 0.32% | 2,195 | Large and mid caps only; much higher fee than VT |
| IXUS (iShares) | International, ex US | 0.07% | 4,580 | Close substitute for VXUS; see VXUS vs IXUS |
| VEU (Vanguard) | International, ex US | 0.04% | 3,810 | Skips small caps |
| ITOT (iShares) | US total market | 0.03% | 2,442 | Close substitute for VTI |
| SCHB (Schwab) | US broad market | 0.03% | 2,390 | Close substitute for VTI |
When all the stock money sits in retirement accounts and you would rather not manage it. Counterexample: a saver with $150,000 in a Roth IRA saves about $34 a year by splitting ((0.06% − 0.0375%) × $150,000 ≈ $34), gets no foreign tax credit, and takes on a rebalancing job and a temptation to overweight whichever region did better lately. For that saver VT does the job. The split earns its keep in taxable accounts and for people who deliberately want a different international share than the market’s. If you prefer iShares, see VXUS vs IXUS; for one fund that also holds bonds, see one-ETF retirement portfolios.
Over the 15 years to June 30, 2026, 90.49% of actively managed US large-cap funds underperformed the S&P 500 (S&P DJI, SPIVA); VT, or VTI plus VXUS, holds the global market for 0.04–0.06%. Market intel adds context for the split you chose; it does not pick your ETFs, tell you when to trade or guarantee better results.
They answer different questions. VT holds global stocks (62.4% US on Sep 30, 2026); VTI holds US stocks only. In a Roth IRA there is no foreign tax credit either way, so the choice is how much international exposure you want.
Almost. VT follows the FTSE Global All Cap Index at market weights; 62.4% VTI plus 37.6% VXUS rebuilds it at a slightly lower cost, about 0.0375% a year against 0.06%.
About 62/38 as of Sep 30, 2026, matching VT’s 62.4% US weight. The ratio moves with markets, so check VT’s fact sheet if you want to stay at market weight.
Generally not. A fund needs more than 50% of its assets in foreign stock to pass the credit through, VT is about 38% foreign, and it was not on Vanguard’s 2025 foreign tax credit list. VXUS was.
In a taxable account you can claim the credit for foreign tax withheld; in an IRA you cannot. Tax-sheltered growth still has value, so many investors place taxable bonds in IRAs first and international stocks in taxable.
For the stock part, yes: about 10,000 stocks worldwide for 0.06%. It holds no bonds, so unlike a target-date fund it does not get more conservative as you approach retirement.
Over the 10 years to Sep 30, 2026, VTI returned 14.70% a year and VT 12.32% (Vanguard NAV), because US stocks led. Over the past year VT did better, 16.32% against 15.33%.
