If a company invests $1,000 in a marketing campaign and gains an additional $1,200 in sales, the ROI would be calculated as ($1,200 - $1,000) / $1,000 = 0.2 or 20%. This indicates a 20% return on the initial investment.
During the meeting, the finance manager highlighted that the ROI for the recent project was exceptionally high, making it a worthwhile investment for the company.
