Return on Investment (ROI)
Return on Investment (ROI) measures the profitability of an investment relative to its cost. In marketing, ROI calculates the net profit generated from marketing activities divided by the total marketing investment, expressed as a percentage.

Formula
ROI = ((Revenue - Cost) ÷ Cost) × 100Where:
Revenue=Total revenue generated from the marketing investmentCost=Total cost of the marketing investment (including ad spend, tools, labor, etc.)Example
Scenario
Your marketing campaign generated $100,000 in revenue. Total costs including ad spend ($20,000), tools ($2,000), and labor ($8,000) were $30,000.
Calculation
ROI = (($100,000 - $30,000) ÷ $30,000) × 100 = 233%Result
Your ROI is 233%, meaning you earned $2.33 in profit for every $1 invested.

Marketing ROI vs. Overall Business ROI
While the formula is the same, marketing ROI specifically measures the return on marketing investments. This includes:
- Direct costs: Ad spend, agency fees, content creation
- Indirect costs: Marketing software, team salaries, overhead allocation
- Opportunity costs: What you could have earned with alternative investments
The challenge with marketing ROI is attribution - determining which revenue should be credited to which marketing activities, especially in multi-channel campaigns.
Frequently Asked Questions
What is a good marketing ROI?
A 5:1 ratio (500% ROI) is generally considered strong for marketing. However, benchmarks vary by industry, campaign type, and attribution model. Brand awareness campaigns may have lower direct ROI but contribute to long-term growth.
How is marketing ROI different from ROAS?
ROI measures net profit relative to total investment, while ROAS measures revenue relative to ad spend only. ROI is a more comprehensive measure because it accounts for all costs, not just advertising.
Why is marketing ROI hard to measure?
Marketing ROI is challenging because of multi-touch attribution, long sales cycles, brand effects that are hard to quantify, and difficulty separating marketing impact from other business factors.
