Historical benchmark

$10,000 invested in IWM at inception (2000) with dividends reinvested through end of 2024 would be worth approximately $62,543 nominal ($33,211 in 2000 dollars). Annualized nominal: 7.61%; real: 4.92%. Small-caps diverge meaningfully from S&P 500 — this proxy is directional only.

Methodology note

How small-caps differ from the headline index

Small-cap indexes like the Russell 2000 hold companies a fraction of the size of S&P 500 members, with higher volatility, more leverage sensitivity, and long stretches of divergence from large caps — which makes the S&P proxy series here an imperfect stand-in, as flagged in the methodology note. Academic research (Fama-French) found a long-run small-cap return premium, but it has been weak since the 1980s. Size the position accordingly.

What 0.19% costs over 30 years

Expense ratios compound against you exactly the way returns compound for you. On a $10,000 position growing at a 10% gross return for 30 years, IWM's 0.19% fee quietly consumes about $8,819 of the final balance. The cheapest fund in the same category, VB at 0.05%, would cost about $2,364 — a difference of $6,455 for holding what is often a near-identical basket.

How this calculator works

For each start year, we apply the year-by-year total return of the Russell 2000 (small-cap; S&P 500 is imperfect proxy) to the entered starting amount, compounding annually with dividends reinvested at year-end. This mirrors what an actual buy-and-hold IWM holder would have experienced, before fees and taxes. Expense ratio is intentionally excluded from the historical result to keep the underlying series comparable across ETFs; for a full lifetime fee estimate at 0.19%, use the projection tab in our fund fee analyzer.
