Calculation Overview

Visualize the power of systematic investing. Compare DCA stock purchases with lump-sum investing over long periods.

Mathematical Model & Formula

FV = PMT * [((1 + r/12)^(12t) - 1) / (r/12)]

Computes the standard ordinary annuity formula representing steady periodic contributions.

Variables Defined:
  • FV: Future portfolio value
  • PMT: Systematic monthly contribution

Worked Example Scenario

Scenario: Investing $300/month at 8% for 5 years.

  1. r = 0.08 / 12 = 0.006667
  2. Periods = 60
  3. Calculate annuity growth: $300 * [(1.006667^60 - 1) / 0.006667] ≈ $22,143

Result: Ending balance is $22,143.
