What is Facebook Ads ROI?
Return on Investment (ROI) measures how profitable your Facebook advertising cost is by comparing the revenue generated to the money spent. In the world of Facebook Ads, ROI shows you whether your campaigns are worth the investment, helping you answer questions like “how much do Facebook ads cost?” relative to their returns. It’s a vital metric for gauging financial success and making informed budgeting decisions.
Facebook Ads ROI Formula
The roi calculation formula for Facebook Ads determines profitability by subtracting total costs from revenue, dividing by total costs, and converting to a percentage. A positive ROI means your campaign is profitable; a negative ROI indicates a loss.

Facebook Ads ROI = ((Total Ad Revenue – Total Ad Cost) / Total Ad Cost) × 100
Explanation:
For a completed campaign:
- Total Ad Cost = Facebook Ad Spend + Additional Costs (e.g., creative fees)
- Total Ad Revenue = Revenue from the campaign
For a future campaign:
- Total Ad Revenue = Target Revenue
- Required Conversions = Target Revenue ÷ Average Revenue per Conversion
- Required Clicks = (Required Conversions ÷ Expected Conversion Rate) × 100
- Total Ad Cost = Required Clicks × Expected Cost-Per-Click (CPC)
This roi calculation formula ensures precise insights into your Facebook ad cost.
How to Calculate Facebook Ads ROI with Example
Imagine you’re promoting a fitness app via Facebook Ads. Here’s how to use the Facebook Ads ROI calculator:
- Facebook Ad Cost: You spend $300 on the campaign.
- Revenue Generated: The campaign drives 50 app subscriptions at $20 each, totaling $1,000.
- Gross Profit: Subtract the cost of goods sold (e.g., $5 per subscription × 50 = $250) from revenue: $1,000 – $250 = $750.
- Net Profit: Subtract the Facebook ad cost from gross profit: $750 – $300 = $450.
- ROI: Divide net profit by ad cost and multiply by 100: ($450 / $300) × 100 = 150%.
A 150% ROI means you earned $1.50 for every dollar spent—a solid return on your Facebook advertising cost.
Understanding Facebook Advertising Costs
To use a Facebook ad cost calculator effectively, you need to understand the components of Facebook advertising cost. The main expense is Cost Per Click (CPC), but you might also use Cost Per Mille (CPM) for impressions or Cost Per Action (CPA) for conversions. Additional costs—like ad design or agency fees—also factor in. Knowing “how much do Facebook ads cost?” depends on targeting, competition, and placement, making a Facebook ad cost calculator invaluable for accurate planning.
ROAS vs. ROI: What’s the Difference?
ROAS (Return on Ad Spend) and ROI (Return on Investment) both assess ad performance, but they differ in scope. A roas calculator shows revenue per dollar spent on ads (Revenue / Ad Spend), while ROI includes all costs for overall profitability ((Revenue – Total Costs) / Total Costs). For instance, if your Facebook ad cost is $300, revenue is $1,000, and total costs are $400, ROAS is $1,000 / $300 = 3.33:1, but ROI is (($1,000 – $400) / $400) = 150%. Use ROAS for ad efficiency and ROI for total campaign success.
Metric | Formula | Focus | Use Case |
---|---|---|---|
ROI | (Revenue – Total Costs) / Total Costs | Overall profitability | Assessing full campaign impact |
ROAS | Revenue / Ad Spend | Ad efficiency | Evaluating ad spend returns |
