Return on Investment (ROI) measures the profitability of an investment relative to its cost. It's one of the most widely used financial metrics because it's simple yet powerful.
ROI answers the fundamental question: "For every dollar I invested, how much did I get back?"
Why ROI Matters:
- Compare different investment opportunities objectively
- Track performance over time
- Justify spending decisions to stakeholders
- Determine if investments are worth continuing
Key Takeaways:
- •ROI is expressed as a percentage
- •Positive ROI means profit; negative means loss
- •Higher ROI generally indicates better performance
- •Always compare similar investment types
Basic ROI Formula: ROI = ((Returns - Investment) / Investment) × 100
Example:
- Investment: $10,000
- Returns: $15,000
- ROI = (($15,000 - $10,000) / $10,000) × 100 = 50%
Annualized ROI Formula: For comparing investments of different durations: Annualized ROI = ((1 + ROI)^(1/years) - 1) × 100
Key Takeaways:
- •Include all costs in your investment figure
- •Use annualized ROI for fair comparisons
- •Account for taxes and fees
- •Track time periods consistently
ROI vs ROAS:
- ROI: Total profitability including all costs
- ROAS: Revenue from advertising relative to ad spend only
ROI vs IRR:
- ROI: Simple percentage return
- IRR: Accounts for timing of cash flows
ROI vs NPV:
- ROI: Doesn't account for time value of money
- NPV: Discounts future returns to present value
Key Takeaways:
- •Use ROAS for advertising-specific analysis
- •Use IRR for complex cash flow timing
- •Use NPV to compare opportunity costs
- •ROI is best for quick comparisons
Stock Market: 7-12% annual (S&P 500 average ~10%) Real Estate: 8-20% annual (varies by market) Venture Capital: 500-1000%+ over 5-10 years SaaS Marketing: 200-500% (6-12 month campaigns) Content Marketing: 100-400% (12-24 months) Paid Advertising: 150-400% (ongoing)
Key Takeaways:
