Frequently Asked Questions
Subtract the total investment cost from the final value to get net profit. Divide that profit by the investment cost, then multiply by 100. For example, a $10,000 investment that returns $12,500 produces $2,500 profit and a 25% ROI.
A negative ROI means the final value is lower than the amount invested. It shows the percentage of invested capital that was not recovered. Review whether every cost and return belongs to the same time period before comparing the result with another project.
ROI compares profit with the money invested. Profit margin compares profit with revenue. A project can have a healthy margin but a weak ROI when it requires a large upfront investment.
Only with care. A 20% return earned in one year is not directly comparable with 20% earned over five years. Use the same analysis period or calculate an annualized return when timing materially affects the decision.
Include the cash and directly attributable costs required to produce the return, such as purchase price, setup, implementation and campaign costs. Keep financing, taxes and overhead treatment consistent across every option you compare.
