What this tool does

Calculate roi from your own entered figures. ROI ignores the time value of money, taxes and fees; the annualised figure assumes the gain accrued evenly (geometric).

How to use the ROI Calculator

  1. Enter or select initial cost / amount invested.
  2. Enter or select final value / amount returned.
  3. Enter or select holding period (years).
  4. Read the calculated result; change any measurement to compare alternatives.

Formula

ROI = (final − cost)/cost × 100; annualised return = (final/cost)^(1/years) − 1
cost
Initial cost / amount invested
final
Final value / amount returned
years
Holding period (years)

ROI ignores the time value of money, taxes and fees; the annualised figure assumes the gain accrued evenly (geometric).
