Custom Metrics allow you to create your own performance metrics by combining existing Meta metrics with mathematical operations. This is useful when you need to track KPIs that are specific to your business.
Getting Started
Navigate to Settings → Space → Custom Metrics
Click the "Add Custom Metric" button
Create your custom metric
Step 1: Name Your Metric
Enter a descriptive name for your custom metric (e.g., "Efficiency Score", "Blended CPA", "Profit Margin").
Step 2: Choose Display Format
Select how the metric value should be displayed:
Currency ($) - For monetary values
Percentage (%) - For ratio or percentage values
Number - For count-based metrics
Step 3: Add a Description (Optional)
Add a brief description to help your team understand what this metric measures.
Step 4: Choose a Color
Select a color for your metric. This color will be used in charts and reports to identify your custom metric.
Step 5: Build Your Formula
This is where you define how your metric is calculated.
Available Tools:
Add Metric - Click to select from existing Meta metrics (Spend, ROAS, CPA, CTR, etc.)
Operators - Use + (add), - (subtract), × (multiply), ÷ (divide)
Parentheses - Use ( and ) to control calculation order
Example Formulas:
Custom Metric | Formula |
Cost Per Click | Spend ÷ Clicks |
Profit | Purchase Value - Spend |
Weighted ROAS | (Purchase Value × 0.8) ÷ Spend |
Efficiency Score | (ROAS + CTR) ÷ CPA |
Tips for Building Formulas:
Click on any token to remove it from the formula
Metrics must be separated by operators
Formulas cannot start or end with an operator
Use parentheses to ensure calculations happen in the correct order
Step 6: Set Performance Direction
Choose what indicates better performance for this metric:
Higher values - Select this if a higher number is better (e.g., ROAS, Revenue)
Lower values - Select this if a lower number is better (e.g., CPA, Cost)
Step 7: Allow Summing
Decide whether this metric can be summed across multiple rows:
Yes - Choose this for additive metrics (e.g., Spend, Revenue, Conversions)
No - Choose this for ratio metrics that should be averaged (e.g., ROAS, CPA, CTR)
Step 8: Create the Metric
Click "Create metric" to save your custom metric.
