What is ROI (Return on Investment)?
A measure of profitability calculated as (Revenue - Cost) / Cost × 100. Shows how much return you get for each dollar invested.

Understanding ROI (Return on Investment)
Return on Investment (ROI) is a performance metric used to evaluate the efficiency or profitability of an investment. It measures the return generated relative to the investment's cost, expressed as a percentage. In marketing and sales, ROI helps determine which initiatives are worth pursuing and how to allocate resources for maximum impact.
ROI is calculated by dividing the net profit (or benefit) from an investment by the cost of that investment, then multiplying by 100 to get a percentage. For marketing campaigns, this might mean comparing revenue generated to campaign costs. For sales tools, it might mean comparing productivity gains to software costs.
While ROI is conceptually simple, accurate calculation requires careful attribution of both costs and benefits. Marketing ROI, in particular, can be challenging because results often involve multiple touchpoints and time delays. Despite these challenges, ROI analysis is essential for making data-driven resource allocation decisions.
Key Points About ROI (Return on Investment)
ROI = (Net Profit / Cost of Investment) × 100
Positive ROI means the investment generated more value than it cost
Marketing ROI requires careful attribution of revenue to campaigns
ROI should be compared across investments to optimize allocation
Consider both short-term and long-term ROI when evaluating initiatives
How to Use ROI (Return on Investment) in Your Business
Define Clear Metrics
Before launching any initiative, define how you'll measure ROI. What counts as revenue or value generated? What costs will you include? What timeframe will you use? Clear upfront definitions prevent confusion and enable accurate analysis.
Track All Costs
Include direct costs (ad spend, tools) and indirect costs (personnel time, overhead allocation). Underestimating costs inflates ROI and leads to poor decisions. Be comprehensive and consistent in what costs you include across different initiatives.
Attribute Revenue Accurately
Use appropriate attribution models to connect revenue to marketing efforts. First-touch, last-touch, linear, and data-driven attribution each have strengths and weaknesses. The right model depends on your sales cycle and marketing mix.
Compare and Optimize
Use ROI comparisons to optimize resource allocation. Shift budget from low-ROI activities to high-ROI ones. But consider ROI alongside volume—a channel with 200% ROI but limited scale may be less valuable than one with 150% ROI that can scale infinitely.
Real-World Examples
Marketing Campaign ROI
A company spends $50,000 on a campaign that generates $150,000 in attributed revenue with 40% margin. Net profit = $60,000. ROI = ($60,000 / $50,000) × 100 = 120%. For every dollar spent, they generated $1.20 in profit.
Sales Tool ROI
A sales team implements a $30,000/year tool that saves each of 10 reps 5 hours weekly. At $75/hour fully-loaded cost, annual savings = 10 × 5 × 52 × $75 = $195,000. ROI = ($195,000 - $30,000) / $30,000 × 100 = 550%.
Content Marketing ROI
A company invests $200,000 in content marketing over a year. Analysis attributes $1.2M in pipeline and $400,000 in closed revenue (with $160,000 margin) to content. Year 1 ROI = -20%. However, evergreen content continues generating leads in year 2, improving cumulative ROI to 180%.
Best Practices
- Define ROI measurement methodology before starting initiatives
- Include all relevant costs, including indirect and opportunity costs
- Use consistent attribution models across different investments
- Consider both immediate and long-term ROI for strategic initiatives
- Compare ROI across investments to optimize resource allocation
- Document assumptions to enable meaningful comparisons over time
Common Mistakes to Avoid
- Underestimating costs by excluding indirect expenses
- Using poor attribution that over-credits or under-credits channels
- Measuring ROI too early before full impact is realized
- Comparing ROI across investments with different measurement standards
- Focusing only on ROI percentage while ignoring absolute value
Frequently Asked Questions
What's a good marketing ROI?
This varies by industry and channel, but many marketers target 5:1 (500% ROI) as a rule of thumb—$5 in revenue for every $1 spent. Brand awareness campaigns may have lower direct ROI. High-intent channels like search often exceed this benchmark.
How do I measure ROI when attribution is unclear?
Use multiple attribution models and triangulate. Compare first-touch, last-touch, and linear attribution. Use incrementality testing where possible. Accept some uncertainty—directional ROI is better than no measurement. Document assumptions clearly.
Should I include salaries in ROI calculations?
For comprehensive ROI, yes—include the cost of personnel time spent on the initiative. This is especially important when comparing outsourced versus in-house options, or when evaluating whether to pursue an initiative at all.
How long should I wait before measuring ROI?
Wait long enough for the full impact to materialize, which depends on your sales cycle. For short cycles (days/weeks), measure within a month. For enterprise sales (months), you may need 6-12 months. Early ROI measurements are directional only.
What's the difference between ROI and ROAS?
ROI measures return on total investment including all costs. ROAS (Return on Ad Spend) specifically measures revenue generated per dollar of advertising spend, excluding other costs like personnel. ROAS is simpler but provides an incomplete picture.
