As discussed above, calculate the profit margin using the same method.

Let's discuss an example of how to calculate the profit margin.

Value of the sale: $200

Cost of the Item: $40

The profit margin formula is given by :

Profit margin = (Sale value - cost of the item)/ sale value

Profit margin = ($200 - $40)/ $200

Profit margin = $160 / $200

Profit margin = 80%

In the above example, your profit margin is 80%.

Your ACOS must not exceed 80% to achieve a break-even (in this case)

Now calculate your ACOS :

As we know, the formula for ACOS is given by

ACOS = Amount spent on the ad/ revenue generated on it * 100

Consider the following data to calculate your ACOS

Ad spend = $1500

Ad revenue = $5000

Calculate your ACOS now

ACOS = Amount spent on the ad/ revenue generated on it * 100

ACOS = $1500 / $5000 * 100

ACOS = 30%

In the above case, your ACOS is 30%.

Compare your ACOS to the profit margin.

Remember that you can determine your break-even once you finished calculating your ACOS and Profit margin.

Points to remember while determining out your break-even point are :

- Having a profit margin more than ACOS says that you are making money from the advertising campaign.
- An Acos higher than that of your profit margin says you are losing money from the advertising campaign.

In the above scenario, the profit margin was 80%.

Your ACOS was 30%.

Considering the case where your ACOS is lower than the profit margin, we can say that you are making money from the campaign. However, if the case conversed, you'd have been losing money from the advertising campaign.
