Understanding This Calculator

ROI Formula

Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment.

ROI = ((Current Value - Cost) / Cost) × 100

  • Current Value: What the investment is worth now
  • Cost: Original purchase price

Example 1

Buy stock for $1,000, sell for $1,200.

  • Profit: 1200 - 1000 = 200
  • ROI: (200 / 1000) × 100 = 20%

Example 2

Buy equipment for $5,000, sell for $3,000.

  • Loss: 3000 - 5000 = -2000
  • ROI: (-2000 / 5000) × 100 = -40%

How to Use

  • Enter what you paid.
  • Enter what it's worth now.
