How to Calculate Fees and Profit Margins
Net Profit = (Ad Spend * ROAS) - Ad Spend - COGS - Processing Fees
Worked Step-by-Step Example
Let's apply this to a real-world scenario. Imagine your product sells for $100. If your platform takes a 15% referral fee ($15) and your payment gateway takes 2.9% + $0.30 ($3.20), your immediate deduction is $18.20. If your COGS (Cost of Goods Sold) is $30 and inbound shipping is $5, your total cost basis is $35. Subtracting both the fees ($18.20) and the cost basis ($35) leaves you with a True Net Profit of $46.80, or a 46.8% net margin. Inputting these exact numbers into the ROAS & Net Profit Calculator above will yield this precise breakdown instantly.
