Compare lump sum vs dollar-cost averaging strategies with historical backtest simulation and volatility impact charts.
A historical comparison shows how an immediate investment and a staged dollar-cost averaging plan would have moved through the same market window. Enter the capital, dates, and contribution cadence available in the calculator, then compare ending values and the volatility-impact charts. The common mistake is treating the winning backtest as a forecast. It represents one realized price path, and the DCA result is especially sensitive to installment dates and the treatment of cash waiting to be invested.
The lump-sum scenario puts the allocated capital into the investment at the beginning of the comparison period. The DCA scenario spreads that capital across multiple purchase dates. Historical prices determine how many units each purchase obtains, so installments made after declines buy more units than equal installments made at higher prices.
The backtest compares how the two timing patterns respond to the selected historical price path. Volatility-impact charts help reveal whether staged purchases softened or merely delayed exposure to price movements. Ending value alone does not show the full experience because two strategies can finish near each other after taking noticeably different routes.
No. It was better by that measure for the selected asset, dates, and schedule. Another starting date or price sequence can reverse the result. The comparison is most useful for understanding timing exposure and historical tradeoffs, not for proving which approach will outperform in the future.
Do not assume they are. Treat an item as included only when the calculator's inputs or results explicitly identify it. These details can materially affect the comparison, particularly when DCA leaves part of the planned investment in cash for an extended period or when frequent purchases incur costs.
