What is BEROAS and Why Does It Matter?

BEROAS (Break-Even Return On Ad Spend) is the single most critical number for media buyers. It represents the "Line in the Sand".

  • If your actual ROAS is higher than your BEROAS, you are Making Money.
  • If your actual ROAS is lower than your BEROAS, you are Losing Money.

Knowing this number allows you to set clear rules for your ads. For example, if your BEROAS is 1.6, you can safely turn off any ad set that is performing at 1.4, because you know for a fact it is unprofitable.

The BEROAS Formula

BEROAS = Selling Price / (Selling Price - Total Costs)

Or, simpler: 1 / Profit Margin %.

Example: You sell a watch for $50. It costs you $25 to buy and ship. Your profit margin is 50%.
Your BEROAS is 1 / 0.50 = 2.0. You need a 2.0 ROAS to break even.

How to Lower Your BEROAS

A lower BEROAS is better because it's easier to hit. Here is how to lower it:

Increase Price

Raising your price increases your margin, which drastically lowers your BEROAS requirement.

Lower COGS

Negotiate with suppliers or switch to cheaper shipping lines to increase the gap between price and cost.

Frequently Asked Questions

A HIGH BEROAS is bad. It means you need very efficient ads just to break even. You want your BEROAS to be as LOW as possible (e.g., 1.2 is amazing, 4.0 is very hard).
This means you are losing money on every unit sold before you even spend a dime on ads. You must raise your prices or lower your costs immediately.
No! BEROAS is where you make $0. You should aim for a Target ROAS that is at least 20-30% higher than your BEROAS to ensure you actually make a profit.
