What is ROI?
ROI (Return on Investment) is a performance metric used to evaluate the efficiency or profitability of an investment. It tells you how much money you earned or lost relative to how much you invested.
✅ Simple ROI Formula:

Where:
- Net Profit = Total Revenue – Total Cost
- Investment Cost = The amount you spent or invested
📊 ROI in a Business Context
ROI helps businesses decide if an investment (like new equipment, marketing, hiring, software, etc.) is worth it. It helps answer:
- “Is this investment profitable?”
- “Which option gives us a better return?”
- “Are we growing or just spending?”
🔍 ROI Example (Simple)
Let’s say you run a small coffee shop.
- You spend $1,000 on Facebook ads.
- The ads bring in $3,000 in extra sales.
- Your cost of delivering those goods is $1,200.
- So, your Net Profit is:

Now calculate ROI:

Meaning: For every dollar you invested in the ad, you got $0.80 in profit. That’s a solid return.
📈 Why ROI Matters to Businesses
- Decision-Making Tool: Helps compare multiple investment options.
- Performance Metric: Measures how well a department or project is doing.
- Budget Justification: Teams use it to justify spending or request more funds.
- Investor Confidence: Investors or owners want to see how money is being multiplied.
🧠 Real-World Applications
1. Marketing Campaigns
- ROI tells if your ad spend brought in enough revenue.
- Example: “We spent $500 on Google Ads and made $1,000 in new sales = 100% ROI.”
2. New Equipment or Technology
- ROI on buying a new machine: Does it save time, reduce costs, or increase output?
3. Employee Training
- Does training improve productivity or reduce costly errors?
4. Website or Software Development
- If you build a new site for $5,000 and it brings $15,000 in new customers, the ROI is high.
⚠️ Limitations of ROI
- Doesn’t Consider Time: An ROI of 100% over 5 years is not as good as 50% in 1 year.
- Ignores Risk: High ROI might come with high risk.
- No Standard Calculation: Different businesses include/exclude different costs.
- Can Be Manipulated: ROI can look good if certain costs are left out.
⏳ Time-Adjusted ROI (Advanced)
To fix the “ignores time” issue, some businesses use:
🔁 Annualized ROI:
Annualized ROI

Where n = number of years
This helps you compare investments with different time frames.
