From the lesson Return on Investment (ROI)
Work through each step on paper or on screen. Use a real business, a project of your own or a friend’s idea. Keep this page for your portfolio.
1Choose a campaign and list every cost.
2Estimate the revenue it produced.
3Calculate ROI with the ROI calculator.
Worked example to compare with: Two campaigns, counted honestly
- Campaign A: ad spend $800 plus $200 for design is a $1,000 cost. It produced $1,500 in sales. ROI is ($1,500 − $1,000) ÷ $1,000 × 100 = 50%.
- Campaign B: ad spend $1,000, a $150 tool and five hours of work valued at $30 an hour ($150) is a $1,300 cost. It produced $3,000. ROI is ($3,000 − $1,300) ÷ $1,300 × 100, about 131%.
- Result: B is clearly better, even after counting the tool and the labor.
- Check: if you leave out labor and tools, B looks like 200% and flatters the result. Count every cost.
