VOO vs VT: Should You Own Just the S&P 500 or the Whole World?
On the last trading day of 1989, Japan's Nikkei closed at 38,915. Japanese companies made up about 45% of the entire world's stock market, well ahead of America at 33%.
If you had asked a room full of professionals that night which single country to bet your retirement on, many would have said Japan. It then took the Nikkei 34 years, until February 2024, just to get back to that number.
Today the country everyone is sure about is America. That is the real question hiding inside VOO vs VT.
Here is the short answer. VOO owns about 500 of the largest US companies for 0.03% a year. VT owns more than 10,000 companies in over 47 countries for 0.06% a year, and about 62% of it is already American. VOO has won the last 15 years by a wide margin. VT is the choice for people who don't want their retirement to depend on guessing which country wins the next 15. And if you live outside the US, the way you buy either one can matter more than which one you pick.
The 30-second answer • VOO = the S&P 500. About 500 big US companies. Fee 0.03% a year. Best 10-year record of the two. • VT = the whole world's stock market. About 10,185 companies. Fee 0.06% a year. About 62% US, 38% everywhere else. • The real choice is not "America or the world". It is "100% America or about 62% America". • Both are excellent. The one you will actually hold through a crash is the right one for you. • Live outside the US? US-listed VOO and VT can cost you a 30% tax on dividends and expose your family to US estate tax. Ireland-listed versions of both ideas exist. |

VOO vs VT at a Glance
Both funds come from Vanguard, the company Jack Bogle founded to sell low-cost index funds. Both are ETFs you can buy through a broker like any share. That is where the similarity ends.
Here are the official numbers from Vanguard's own fact sheets, as of 30 September 2026.
VOO (Vanguard S&P 500 ETF) | VT (Vanguard Total World Stock ETF) | |
What it tracks | S&P 500 Index | FTSE Global All Cap Index |
Number of stocks | 505 | 10,185 |
Countries | 1 (United States) | 47+ developed and emerging |
Company sizes | Large only | Large, mid and small |
Expense ratio | 0.03% a year | 0.06% a year |
Cost on $10,000 | $3 a year | $6 a year |
Top 10 holdings | 40.6% of the fund | 23.5% of the fund |
US share | 100% | 62.4% |
Price/earnings ratio | 24.7x | 20.4x |
10-year return (a year) | 15.29% | 12.32% |
Fund size | About $1.73 trillion | About $101 billion |
Two numbers jump out. VOO is twice as expensive in percentage terms, but the gap is $3 a year on $10,000. Nobody's retirement is made or broken by $3.
The numbers that really matter are the ones further down: how many eggs sit in how few baskets, and how much you are paying for each dollar of company profits.
The Surprise: VT Is Already About 62% American
Most people picture VT as the "international" fund and VOO as the "American" fund. That picture is wrong.
VT simply buys the world's stock market in proportion to each company's size. Because American companies are worth so much, America ends up as 62.4% of VT. Japan is next at 6.0%. Every other country is smaller still.
So VT is not a bet against America. Its five largest holdings are NVIDIA, Apple, Microsoft, Alphabet and Amazon, the same giants at the top of VOO. The biggest chunk of your money in VT goes into the very same companies VOO owns.
What VT adds is the other 38%: Toyota and Sony in Japan, TSMC in Taiwan, Samsung in Korea, Nestlé in Switzerland, banks in Canada and Australia, plus thousands of smaller American companies VOO leaves out.
That changes the question completely. You are not choosing between America and the rest of the world. You are choosing between 100% America and roughly 62% America.
Why this matters If you already believe America will keep leading, VT still gives you a lot of America. If you are wrong, VT gives you a cushion. Seeing it this way takes much of the fear out of the decision. |
What You Really Own Inside VOO
"500 companies" sounds like the ultimate safety net. In 2026 it is less spread out than it sounds.
The S&P 500 weights each company by its market value. When a few companies grow enormous, they take over the index. Today the 10 largest holdings make up 40.6% of VOO. NVIDIA alone is 8.4%.
A decade ago the top 10 were roughly 19% of the index, according to S&P Dow Jones Indices data reported in the financial press. The index has become far more top-heavy.
VT spreads the same money more widely. Its top 10 are 23.5% of the fund, and NVIDIA is 4.6%. Technology is still the biggest sector in both, about 40% of VOO and about 34% of VT (Vanguard uses slightly different sector labels for each fund).
None of this means VOO is dangerous. Those top companies earn real, very large profits. It means a VOO owner is making a bigger bet on a small group of American technology giants than most people realise.

The Scoreboard: How VOO and VT Have Actually Performed
Let's look at the results honestly. Here are average yearly returns, dividends reinvested, from Vanguard's fact sheets to 30 September 2026.
Period | VOO | VT | Winner |
2026 so far (9 months) | 12.72% | 12.83% | VT, just |
1 year | 15.70% | 16.32% | VT |
3 years | 22.85% | 21.42% | VOO |
5 years | 13.75% | 11.34% | VOO |
10 years | 15.29% | 12.32% | VOO |
Over 10 years, the gap is large. Using those average returns, $10,000 in VOO would have grown to about $41,500. The same $10,000 in VT would have grown to about $32,000. That is roughly $9,500 more for the VOO owner.
But look at the top of the table. Over the last 12 months, and so far in 2026, the whole world has kept pace with America or edged ahead.
VT also bounced around a little less. Vanguard measures its three-year volatility (standard deviation) at 11.80%, against 12.43% for VOO.
The trap in this table Almost everyone who reads the 10-year column concludes "VOO is better". That is exactly how the people who piled into Japan in 1989 thought. The last 10 years tell you what happened, not what will happen. |
The Case for VOO: Just the S&P 500
The case for owning only the S&P 500 is strong, and it comes from two of the most respected names in investing.
Warren Buffett told his own trustee to use it
In his 2013 letter to Berkshire Hathaway shareholders, Buffett revealed the instructions in his will for the money he leaves his wife. 90% goes into a very low-cost S&P 500 index fund and 10% into short-term government bonds. He added: "I suggest Vanguard's."
He did not say "a world index fund". He said the S&P 500. You can read more in Why the World's Greatest Stock Picker Keeps Telling Ordinary People NOT to Pick Stocks.
Jack Bogle said you don't need international stocks
Bogle, the father of the index fund, held this view for decades. He told InvestmentNews that "you don't need to own international stock". His advice was that if you want some anyway, keep it to no more than 20%.
His reasoning: big American companies already sell all over the world. In S&P Dow Jones Indices' 2018 report, 42.9% of S&P 500 company sales came from outside the US. A 2025 UBS estimate put it at about 35%. When you buy Apple or Coca-Cola, you already earn money from customers in Kuala Lumpur, London and Lagos. (More of his thinking is in Jack Bogle's 10 Rules for Investors Who Are Tired of Losing Money.)
America has earned its place
The UBS Global Investment Returns Yearbook 2026 shows America grew from about 15% of the world's stock market in 1900 to about 62% today. The Yearbook's authors credit strong long-term returns and a huge volume of new listings. America has the world's deepest markets, strong shareholder rights and many of the world's most profitable companies.
It is cheaper and simpler
VOO costs half as much as VT in percentage terms. It is easier to understand. And over every 20-year period since 1926, the S&P 500 has never lost money (see Has the S&P 500 Ever Lost Money Over 20 Years?).
The Case for VT: The Whole World
The case for VT is not that America will fail. It is that nobody, including the experts, knows which country will lead next, and history shows the leader changes more often than people think.
The leader always looks permanent, until it isn't
In 1900, Britain was the world's biggest stock market at roughly a quarter of world value. Today it is about 3.7%. Japan went from about 45% of the world market in 1989 to about 6% today. America went the other way, from about 15% to about 62%.
Each of those shifts took decades. Each time, the investors living through it were sure the leader of their day would stay on top.
If you want the full story of what Japan's long wait would feel like for an S&P 500 owner, read What If the S&P 500 Does What Japan Did?
America has had its own lost decade
From January 2000 to December 2009, the S&P 500 returned about minus 0.95% a year, according to Dimensional. A $10,000 investment at the start of 2000 was worth about $9,089 ten years later.
Over that same decade, developed markets outside the US earned about 1.2% a year and emerging markets about 10.1% a year, according to a Minnesota state pension commission report. A world fund would have given you something while the S&P 500 gave you nothing.
The table then turned. In the 15 years to the end of 2025, the S&P 500 earned 14.06% a year against 6.64% for developed international stocks. Then in 2025 itself, it flipped again: international developed stocks returned 31.22% against 17.88% for the S&P 500.
Leadership comes in long waves. A world fund means you never have to guess when the wave turns.
Prices are not equal
You pay 24.7 times earnings for VOO and 20.4 times for VT as a whole. The non-US part is cheaper still. Envestnet reported that stocks outside the US recently traded at about a 32% discount to US stocks, far deeper than the 20-year average discount of 19%.
A higher price can be justified by faster growth. But history suggests a higher starting price has tended to mean lower returns over the following decade.
Many forecasters now lean towards the rest of the world
In its 2026 outlook, Vanguard forecast average US stock returns of only 4% to 5% a year over the next 5 to 10 years. It ranked non-US developed-market stocks among the best risk-reward choices for that period.
Vanguard is not alone. In Morningstar's yearly survey of big investment firms, most expected higher returns from non-US stocks than US stocks over the next decade.
Be careful with this one, though. Forecasters have been saying this for years while America kept winning. Treat forecasts as a reason to diversify, not as a promise.
Vanguard's own research on how much to hold abroad
In a 2019 study, Vanguard found that in every market it examined, portfolio swings were reduced most with 40% to 50% in international stocks. Most of the benefit had already arrived at about 20%.
VT gives you about 38% international automatically. That sits right inside the range Vanguard's research found most helpful.
Why "US Companies Sell Abroad" Isn't the Same as Owning Abroad
Bogle's revenue argument is the most common reason people give for skipping international stocks. It is half right.
Yes, Apple sells iPhones in Malaysia. But Apple's share price still rises and falls with the American stock market, American interest rates and American valuations. Morningstar analyst David Harrell made this point: revenue from abroad changes each company's business, but it does not give your portfolio the diversification of actually owning foreign companies.
When the S&P 500 lost a decade from 2000 to 2009, America's global companies did not rescue it. Owning Samsung, Nestlé and Toyota directly is a different thing from owning American companies that sell to their customers.
The Part Most VOO vs VT Articles Miss: Taxes If You Live Outside the US
Almost every VOO vs VT comparison online is written for Americans. If you live in Malaysia, Singapore, India, Indonesia or many other countries, two hidden costs can matter more than the difference between the funds themselves.
No. 1: The 30% dividend tax
VOO and VT are both US-registered funds. When they pay you a dividend, the US withholds tax before the money reaches you. For countries with no US tax treaty, the rate is 30%.
Malaysia is one of them. EY's ASEAN tax leader Amarjeet Singh told The Edge Malaysia that direct holders of US-domiciled ETFs face a 30% dividend withholding tax because Malaysia has no tax treaty with the US. Filling in a W-8BEN form does not lower it for Malaysians; it only confirms the 30%.
Funds based in Ireland work differently. Under the US-Ireland tax treaty, an Irish fund holding US shares pays 15% at the fund level, half the rate.
Here is a simple worked example. Say you hold $100,000 and it pays about 1% a year in dividends, which is $1,000. Through a US-listed fund you would keep about $700. Through an Ireland-domiciled fund holding the same US shares you would keep about $850. That is about $150 more every year, before it compounds.
Full details are in The 30% Dividend Tax You Didn't Know You Pay on US Stocks.
No. 2: The US estate tax at just $60,000
This is the one that keeps families up at night. If you are not a US citizen or resident and you die holding more than $60,000 of US assets, which includes US-listed ETFs like VOO and VT, the IRS says your estate generally has to file a US estate tax return. Rates on the taxable amount run from 18% up to 40%.
The Edge Malaysia's report also noted that non-resident investors in Irish-domiciled ETFs avoid this US estate tax exposure. We explain the whole trap in If You Live Outside America and Own VOO, Your Family Could Lose Up to 40% of It.
The Ireland-listed versions of each idea
You can get both strategies through Irish funds listed on the London Stock Exchange:
Strategy | US-listed fund | Ireland-listed version | Yearly fee |
Just the S&P 500 | VOO | VUAA (Vanguard) or CSPX (iShares) | 0.07% |
The whole world | VT | VWRA (Vanguard FTSE All-World) | 0.14% |
Two honest notes. First, the Irish versions charge a little more, but for many non-US investors the tax saving is larger than the fee gap. Second, VWRA holds about 4,000 large and mid-sized companies, not VT's 10,000-plus, because it leaves out small companies. The broad result is very similar.

If you live outside the US For many readers, the bigger decision is not "VOO or VT" but "US-listed or Ireland-listed". Tax rules differ by country and change over time, so check your own situation with a qualified tax adviser before you buy. |
The Behaviour Test: Which One Will You Actually Hold?
Here is something the return tables never show. The best fund on paper is useless if you sell it at the wrong moment.
Imagine owning only VOO from 2000 to 2009. Ten years of saving, and your money was worth less at the end. Many people gave up.
Now imagine owning VT through the 2010s. Every year you would have watched friends with the S&P 500 pull further ahead. Many people gave up on that too, often right before 2025, when the rest of the world finally had its big year.
Both funds will test you. VOO tests you when America has a bad decade. VT tests you when America has a great one and you own "only" 62% of it.
So ask yourself honestly: which kind of disappointment can you live with for ten years without selling? Your answer is worth more than any forecast. (If selling at the bottom has hurt you before, read Why Smart, Hard-Working People Sell at the Very Bottom.)
A Simple Way to Decide
Use this flowchart as a starting point. It is a way to organise your own thinking, not a recommendation.
VOO-style (just the S&P 500) may suit you if
You agree with Buffett and Bogle that America's global giants give you enough of the world.
You want the lowest possible cost and the simplest possible portfolio.
You can stay calm through a long stretch when the S&P 500 goes nowhere.
VT-style (the whole world) may suit you if
You don't want your retirement to depend on one country staying on top.
You want to own the world's market as it is, with no country bet at all.
You can stay calm watching America beat your fund in some years.
A middle path many people use
You don't have to choose 100% one way. Some investors hold mostly an S&P 500 fund plus a smaller slice of an international fund, staying under Bogle's 20% limit or nearer Vanguard's 40%. Others simply hold VT (or VWRA) and never think about it again.
What matters is picking a mix you understand, writing it down, and sticking to it. For more on keeping it simple, read How Many Index Funds Should You Own? Probably Fewer Than You Think and The Lazy 3-Fund Portfolio.
6 Mistakes to Avoid
No. 1: Owning VOO and VT together and thinking you've doubled your safety
VT already contains the companies in VOO. Holding both simply tilts you further towards America. That's fine if you mean it, but it is not extra diversification.
No. 2: Switching after a hot year
International stocks had a huge 2025. US stocks had a huge 2023 and 2024. Jumping to whichever won last year is how people buy high and sell low.
No. 3: Choosing only by the last 10 years
The 10-year column tells you who won the last race. In 1989, the 10-year column said Japan.
No. 4: Ignoring where the fund is registered
For non-US investors, a 30% versus 15% dividend tax and the $60,000 estate tax rule can outweigh the whole VOO vs VT difference.
No. 5: Paying high fees for "global" investing
A global unit trust charging 1.5% or more a year will very likely cost you far more than any choice between these two funds. See Unit Trust vs ETF in Malaysia: The Fees Your Agent Never Showed You and The "Tiny" 1% Fee That Can Quietly Steal a Quarter of Your Retirement.
No. 6: Waiting for the "perfect" answer
The cost of not investing at all, year after year, is bigger than the gap between VOO and VT. Both are among the best tools ever made for ordinary savers.
What to Do Tonight
Write down your answer to one question: "Do I want to bet on America, or own the world?" There is no wrong answer, only an honest one.
Check where you live for tax. If you are outside the US, look at the Ireland-listed versions (VUAA or CSPX, and VWRA) before buying VOO or VT.
Look at what you already own. If you already hold an S&P 500 fund, adding VT mostly adds more America. Decide your total US share on purpose.
Pick one fund or a fixed mix. Write the percentages on paper and keep it where you'll see it.
Set up a monthly amount and automate it. Then stop checking which fund "won" this week.
Frequently Asked Questions
Is VT better than VOO?
Neither is better in every period. VOO has returned more over the last 10 years (15.29% a year vs 12.32% to September 2026), while VT is more diversified, slightly less volatile and has kept pace in 2026. VT suits people who don't want to bet on one country; VOO suits people confident in America.
Is VT just VOO plus international stocks?
Roughly, yes. VT holds the big US companies found in VOO, plus thousands of smaller US companies and about 38% in stocks outside America. As of September 2026, the US made up 62.4% of VT, with Japan next at 6.0%.
Should I own both VOO and VT?
You can, but it is not extra diversification. VT already contains VOO's companies, so holding both simply raises your US share above about 62%. If you want more America than VT gives you, holding both is one way to do it; just choose the mix on purpose.
Why has VOO beaten VT for so long?
Mainly because large American technology companies grew profits and share prices far faster than the rest of the world after 2010, and the US dollar was strong. In the 2000s it was the other way round: the S&P 500 lost about 0.95% a year while emerging markets gained about 10% a year.
What is the difference in fees between VOO and VT?
VOO's expense ratio is 0.03% a year and VT's is 0.06%. On a $10,000 investment that is $3 a year versus $6 a year. Both are among the cheapest funds in the world, so the fee difference should rarely decide your choice.
What is the best VT alternative for investors outside the US?
Many non-US investors look at Vanguard FTSE All-World UCITS ETF (VWRA), listed in London and domiciled in Ireland, which charges 0.14% a year. For the S&P 500 side, VUAA and CSPX charge 0.07%. Irish funds pay 15% US dividend tax instead of 30% and avoid US estate tax exposure.
Does VT pay more dividends than VOO?
Usually, yes. VT's dividend yield has recently been around 1.5% a year, compared with around 1% for VOO, because companies outside the US tend to pay out more of their profits. Remember that non-US investors may lose 30% of those dividends to US withholding tax.
Is VOO diversified enough on its own?
VOO owns about 500 companies across every sector, which is far more diversified than picking stocks. But it holds only one country, and its top 10 holdings make up about 40% of the fund. Whether that is enough depends on how much you trust America to keep leading.
The Bottom Line
VOO and VT are both wonderful tools. Either one, bought cheaply and held for decades, puts you ahead of most professional money managers and far ahead of anyone chasing hot tips.
VOO is a confident bet on America, backed by Buffett's own will. VT is a humble bet on the whole world, backed by the history of Britain, Japan and America's own lost decade.
You don't need to know who wins the next 15 years. You only need a choice you understand, a plan you can stick to, and the patience to let compounding do the heavy lifting.
If you have been burned in the stock market before, that patience is the real edge. And it is one that nobody can take away from you.
