What 2008 actually was: into the crash
Starting a DCA in 2008 is the most-asked counterfactual in personal finance. You bought into a full-scale collapse for an entire year, then bought even cheaper through 2009. The recovery rewarded patience: those low-price purchases compounded for the next 15 years. This is the year DCA defenders point to when arguing against trying to time the market.
For a S&P 500 DCA buyer who started January 2008 with $500 a month, the schedule pulled in 223 purchases through 2026-07-24. Total invested: $111,500. Final value: $400,309. That works out to an annualized return of 12.41% per year on the irregular cashflow series.
The numbers above use adjusted closing prices (dividends reinvested, splits applied) and apply a T+1 policy: when the 1st of the month landed on a weekend or holiday, the trade executed at the next trading day's close. Bitcoin pages execute on the exact scheduled date because crypto trades 24/7.
