How to Calculate Return on Investment (ROI)
Return on Investment (ROI) is a standard performance metric used to evaluate the efficiency and profitability of an investment or compare the relative returns of multiple commercial projects, marketing campaigns, or capital expenditures.
Simple ROI measures raw holding period return without adjusting for holding duration, inflation, tax liabilities, or capital opportunity cost. Do not rely solely on simple ROI for multi-year capital allocation decisions.
Formula: ROI (%) = (Net Return / Amount Invested) * 100. Directly expresses net gain as a percentage proportion of initial capital risked.
Standardizes comparison across unequal capital scales—allowing you to compare a $5,000 marketing pilot against a $50,000 equipment upgrade.
Worked ROI Examples
Example 1 (Profitable Marketing Campaign):
• Amount Invested: $10,000 | Net Return (Profit): $2,500
• ROI: ($2,500 / $10,000) * 100 = 25.00%
Example 2 (Unprofitable Equipment Trial):
• Amount Invested: $10,000 | Net Return (Loss): -$1,500
• ROI: (-$1,500 / $10,000) * 100 = -15.00%

Frequently Asked Questions
What is the standard formula for Return on Investment (ROI)?
Simple Return on Investment is calculated as: ROI (%) = (Net Return / Investment Cost) * 100. For example, if you invest $10,000 and realize a net profit of $2,500, the ROI is ($2,500 / $10,000) * 100 = 25%.
Can Return on Investment (ROI) be negative?
Yes. If the total revenue returned from an investment is less than the capital invested, net return is negative and the resulting ROI is negative, indicating an absolute financial loss on the venture.
Does simple ROI take holding time into consideration?
No. Simple ROI measures cumulative percentage gain or loss regardless of whether the investment took 6 months or 6 years to mature. For multi-year annualized performance comparisons, use CAGR (Compound Annual Growth Rate).
What is the difference between ROI and CAGR?
ROI measures total percentage efficiency over the entire holding period: (Net Profit / Cost) * 100. CAGR annualizes the compound growth rate year-over-year: [(Final Value / Initial Value)^(1/t) - 1] * 100.
What expenditures should be included in the initial investment cost?
A thorough ROI calculation should include all acquisition expenses, setup fees, software subscriptions, shipping, maintenance, and advertising costs necessary to generate the returns.
