See what steady monthly investing becomes — a DCA calculator
A dollar-cost averaging (DCA) calculator shows what you'd have if you invested a fixed amount every month. Enter your monthly contribution, annual return, and period to instantly see the estimated final amount — and add an initial investment too.
Instead of a single lump sum, you invest in equal pieces over time, so you buy at an average price as prices rise and fall. This calculator shows how it grows with monthly compounding.
Principal and gains, shown separately
Results split into 'final amount', 'total invested', and 'total gain (return)'. Seeing the money you actually put in versus the part that grew from returns makes it clear how compounding builds up over time.
The longer the period, the bigger the share that gains take over principal. Try 10, 20, and 30 years to compare.
How to use it
Great for planning like 'what if I save $300 a month for 20 years?' or 'assuming 7% a year, how big is my retirement fund?' Nudge the monthly amount or the return to find the mix that hits your goal.
The annual return is an assumption, not a guarantee. Real returns vary and can be negative, so use the result as a planning reference.
