Stocks vs ETFs: Which Wins Over 10, 20 and 30 Years?

What does the ETF winning by $3,210.00 mean?

It means that, over 20 years, the same $10,000.00 grows to $66,908.99 in the ETF and to $63,698.99 in the 10-stock portfolio — a $3,210.00 gap, on identical gross returns of about 10% a year. The gap is not the return: the stock portfolio actually aims higher, 10.20% gross against the ETF's 10.00%. The gap is the fee drag. The stock portfolio pays 0.50% a year in trading costs — commissions, spreads, turnover — which takes $6,065.09 off the $69,764.08 it would have reached for free. The ETF pays 0.03% — $3 a year per $10,000.00 — which takes only $366.01 off its $67,275.00. The net returns are 9.70% against 9.97%, and 0.27 points a year, compounded for 20 years, is $3,210.00.

Three things to check before you trust the number

The fee drag grows with time, not with the fee. At 10 years the gap is only $628.11; at 30 years it is $12,304.27 — the same 0.47-point fee difference, compounding for a decade longer. A 0.50% trading cost sounds small against a 10.2% return, but over 20 years it takes $6,065.09 off a $10,000.00 investment — about 8.7% of the gross value. Raise the trading costs to 1.00% a year and the gap jumps to $8,771.97; raise the ETF expense to 0.10% and it shrinks to $2,363.33. The fee is the lever, and time is the multiplier.

The stock portfolio has to earn its fee back. Your 10 stocks start 0.47 points a year behind the ETF, so they need a gross return of 10.47% a year just to tie — and at 12% gross they win by $21,296.85 over 20 years. That is the whole stock-picking question in one number: can you beat the market by half a point a year, every year, for 20 years? Over the past 15 years the S&P 500 beat about 90% of managed large-cap funds, which is the honest base rate for the attempt. If the answer is no, the ETF wins by default — and if the answer is yes, the calculator says exactly how much the win is worth.

Ten stocks is a concentration bet, not a market bet. One bad pick in a 10-stock portfolio is 10% of the money; one bad pick in the 500-stock ETF is 0.2%. In a 2008-style year the market fell 37% — the site's own stocks-vs-bonds page works that year out — and a 10-stock portfolio can fall further than the market if one of its ten is the one that falls hardest. The model does not price that risk: both sides compound at a smooth yearly rate, with no down years at all. The ETF's case is not just the fee — it is that the fee buys 500 stocks of diversification, and the stock portfolio's case has to be worth giving that up.

Worked example

On the defaults: $10,000 over 20 years, stocks at 10.2% gross minus 0.50% trading costs, the ETF at 10.0% gross minus 0.03% expenses.

1. Stock net return: 10.2% − 0.50% is 9.70%.
2. ETF net return: 10.0% − 0.03% is 9.97%.
3. Stock future value: $10,000 × 1.0970^20 is $63,698.99.
4. ETF future value: $10,000 × 1.0997^20 is $66,908.99.
5. The fee drag: $69,764.08 − $63,698.99 is $6,065.09 on the stocks; $67,275.00 − $66,908.99 is $366.01 on the ETF.
6. The difference: $66,908.99 − $63,698.99 is $3,210.00 — the ETF wins.

And the other way: the stock portfolio needs 10.47% a year gross to tie the ETF, the ETF expense would have to rise to 0.30% a year to tie the stocks, and the ETF passes $50,000 in 17 years.

What the defaults assume

The defaults are $10,000 invested once, 20 years, a 10-stock portfolio at 10.2% gross a year minus 0.50% trading costs, and a 500-stock ETF at 10.0% gross a year minus a 0.03% expense ratio. The stock gross return of 10.2% is the site's own figure — the stocks-vs-bonds page turns $10,000 into $69,764 in 20 years at 10.2% — and the ETF gross return of 10.0% is the S&P 500 long-run average of about 10% a year since 1957 (Fidelity: 20-year average 11%, 30-year 10.4% through December 2025). The 0.03% ETF expense is VOO's published ratio — $3 a year per $10,000 invested. The 0.50% stock trading-cost drag is the model's own illustrative assumption — commissions, spreads and turnover on a portfolio that trades — not a measured average, and the page says so. The model compounds once a year at a smooth rate: no down years, no dividends taken out, no tax, no extra contributions, and no rebalancing. The past decade ran far above the long-run average — VOO averaged 15.4% a year over the 10 years to August 2026 — and the next decade may not repeat it. The reverses are checked at 0.01 points either side, because a 0.01-point change in a yearly return moves a 20-year future value by about $130 and shows the tie clearly. The holdings count does not change the future value in this model — it is shown because one bad pick is 10% of a 10-stock portfolio and 0.2% of the ETF, and that is the diversification gap the fee buys.

These notes repeat in every explainer section because this page is built to be read start to finish: the fee drag grows with time, not with the fee; the stock portfolio has to earn its fee back; and ten stocks is a concentration bet, not a market bet.

Who uses this

• An investor choosing between picking stocks and buying the index — $10,000.00 over 20 years is $63,698.99 picked and $66,908.99 indexed: the $3,210.00 gap is the price of picking.
• A saver checking what fees really cost — 0.50% a year costs $6,065.09 over 20 years while 0.03% costs $366.01: the fee drag, priced.
• A stock picker testing the hurdle — 10.47% a year gross ties the ETF: the return the picks have to beat, every year, for 20 years.
• A student learning compound fees — one worked example from gross return to net return to future value to fee drag, and the branches that show how the years, the returns and the fees each move the winner.

Accuracy & limitations

Figures are the model's own future values on the numbers you type, computed from unrounded values: each net return is the gross return minus the annual fee, each future value is the amount times one plus the net return to the power of the years, the fee drag is the gross future value minus the net future value, and the difference is the ETF value minus the stock value. The displayed figures are rounded to 2dp. The returns are illustrative assumptions, not forecasts: the S&P 500 has averaged about 10% a year over many decades, the past 10 years averaged 15.4% for VOO, and any single 20-year period can land well above or below the average. The model compounds once a year at a smooth rate — it has no down years, no sequence-of-returns risk, no dividends taken out, no tax, no extra contributions and no rebalancing. The 0.50% stock trading-cost drag is the model's illustrative assumption, not a measured average. The ETF expense of 0.03% is VOO's published ratio as of October 2026; other ETFs charge more. The holdings count does not change the future value — it is shown to frame the diversification gap. This page is a calculation tool, not financial advice, and not an investment recommendation.
