Formulas and Equations

1. Advertising Cost of Sales (ACOS)

ACOS tells you what percentage of your revenue was spent on advertising.

$\text{ACOS ($

2. Total Profit or Loss

This measures how much profit (or loss) remains after subtracting advertising costs from revenue.

$\text{Profit/Loss} = \text{Total Sales Revenue} - \text{Total Advertising Cost}$

Example Calculation

Let’s say:

• Total Advertising Cost = $1,200
• Total Sales Revenue = $4,000

Step 1: Calculate ACOS

$\text{ACOS} = \left( \frac{1200}{4000} \right) \times 100 = 30\%$

Step 2: Calculate Profit or Loss

$\text{Profit/Loss} = 4000 - 1200 = 2800$

So, your advertising campaign spent $1,200 and earned $4,000 in revenue, resulting in a 30% ACOS and a $2,800 profit.
