Dollar Cost Averaging Calculator
Estimate the future value of a dollar-cost-averaging (DCA) strategy where you invest a fixed monthly amount over a chosen period, given an assumed average annual return and a volatility multiplier. Use it to project the outcome of regular index-fund contributions or to compare DCA against a lump-sum alternative.
