Worked accounting example
Investment A costs $5,000 and returns $6,000: net gain $1,000 and ROI 20%. Investment B costs $8,000 and returns $9,200: net gain $1,200 but ROI only 15%. Project A wins on ROI.
Accounting formulas and common mistakes
ROI = (proceeds − purchase cost) ÷ purchase cost × 100. The highest profit in dollars is not necessarily the highest percentage return. ROI alone ignores risk, duration and capital constraints.
All fictional amounts use US dollars for illustration only. Exercises are educational, not business, tax or investment advice.
Frequently asked questions
Does a bigger dollar profit always mean higher ROI?
No. An investment with more capital at risk can deliver a larger profit but a lower ROI percentage.
Does ROI tell me which stock to buy?
No. These fictional exercises teach arithmetic and do not assess investment risk or investment suitability.
