Calculation Assumptions

Results can differ across apps when compounding or contribution timing assumptions change.

  • Investment growth compounds annually at the entered expected return rate for the full time horizon.
  • Depreciation is modeled as a constant annual percentage decline based on the selected category.
  • Opportunity cost is the future value of the investment minus the original purchase price; taxes and inflation are not modeled.
