How the calculation works
Profit = revenue − costs; profit margin = profit ÷ revenue × 100
Example
Revenue of $50,000 and total costs of $35,000 produce $15,000 profit and a 30% margin.
Why this result matters
Margin shows how much of each revenue dollar remains after the costs entered, making projects of different sizes easier to compare.
Tips for a more useful estimate
- Include platform fees and marketing.
- Separate one-time and recurring costs.
- Use net revenue when available.
Frequently asked questions
Can margin be negative?
Yes. Costs above revenue produce a loss and negative margin.
Is margin the same as markup?
