How to use the Dollar Cost Averaging Calculator

Model regular monthly investing and compare total deposits with an assumed compounded future balance.

Calculation formula

Projected balance = initial × (1 + r)^n + monthly contribution × [((1+r)^n − 1) ÷ r]; r = annual rate/12, deposits at month-end.

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations

Assumes smooth monthly compounding and constant returns. Market investments fluctuate; a constant rate is not a prediction.
