ROI Calculator (Return on Investment)
ROI (Return on Investment) measures total profitability. Unlike ROAS (which only accounts for revenue), ROI accounts for real profit after deducting all costs.
Frequently Asked Questions (FAQ)
What is the difference between ROI 100% and ROAS 100%?
Huge! ROAS 100% (1:1) means you broke even on ad spend (revenue equals ad cost), but after margins, you are likely losing money. ROI 100% means you not only broke even but made 100% profit on top (doubled your investment).
What belongs in "Other Costs"?
Include everything you wouldn't spend without the campaign: agency/freelancer fees, software costs (e.g., banner maker licenses), influencer costs, etc.
Can ROI be negative?
Yes, and it often is. ROI -50% means you lost half of your investment. ROI -100% means you lost everything (no revenue). ROI cannot be lower than -100% (unless we count lost time).
Why it matters
Many marketers boast about high ROAS, but business owners care about ROI. You can have ROAS 8:1 on
Facebook, but if you spent $10,000 on video production and $5,000 on an agency, your real ROI might be
miserable.

churns money.
