What If Scenario
What If You Invested $100/Month for 20 Years?
$100 a month does not sound like much. Invested consistently for 20 years, that $24,000 in contributions had a long time to compound, and the earliest dollars did most of the work.

Based on price data through 2026-06-01. Price return only (no dividends).
About this calculation
$100/month = $1,200/year. We calculated annual lump-sum purchases at start-of-year prices for each year from 2005-2024, then computed cumulative returns through today. Real DCA (monthly) returns would differ slightly.
Returns are based on price appreciation only (no dividends reinvested). Past performance does not guarantee future results. Not financial advice.
