How this is calculated

  1. 1

    Grow the starting amount

    FV = P × (1 + i)ⁿ

    FV = $10,000.00 × (1 + 0.005833)^240

    = $40,387.39

  2. 2

    Grow the regular contributions

    FV = C × ((1 + i)ⁿ − 1) ÷ i

    FV = $500.00 × ((1 + 0.005833)^240 − 1) ÷ 0.005833

    = $260,463.33

  3. 3

    Add both together

    total = FV(principal) + FV(contributions)

    total = $40,387.39 + $260,463.33

    = $300,850.72

  • Returns are assumed constant. Real markets vary, and this ignores tax, fees and inflation.

How to use this dividend reinvestment calculator

  1. Fill in your values. Every field starts with a sensible default, so you can change one number at a time and watch what it does to the result.
