The lowest return on ad spend (ROAS) at which your ads pay for the product costs of the sales they bring in, so you neither make nor lose money on the first order.

Use our free ROAS Calculator to see your break-even ROAS next to the ROAS you actually get.

Why It Matters

A ROAS number on its own does not tell you whether your ads make money. Your break-even ROAS does: it is the line your ads have to clear before a single dollar of profit shows up. Knowing it turns "is 2x good?" into a yes or no for your store.

Formula

Break-Even ROAS=1/Gross Margin (as a decimal)
Example: Break-Even ROAS = 1 / 0.60 = 1.67x

Practical Example

Scenario

You sell a $50 candle that costs you $20 to make and ship, so your gross margin is 60%.

Calculation

Break-Even ROAS = 1 / 0.60 = 1.67x

Result

Your ads have to bring in at least $1.67 for every $1 they cost just to cover the candle. At 1.5x you are losing money on every sale; at 2.5x there is room left for overhead and profit.

In-Depth Explanation

Below it, every sale your ads bring in loses money once you pay for the product. Above it, the gap is what is left for overhead and profit. It comes from your margin, not from your ad account, so two stores with the same ROAS can sit on opposite sides of it.

Pro Tips

  • 1Work it out per product or collection, not just store-wide. A low-margin bestseller can need a much higher ROAS than your average.
  • 2Treat break-even as the floor, not the goal. Your target ROAS needs room above it for overhead, returns and profit.
  • 3Recalculate whenever costs move: a price change, a new supplier or higher shipping rates all shift the line.

Common Mistakes to Avoid

Using a benchmark from someone else instead of your own margin. The line depends entirely on your numbers.
Leaving shipping, packaging and payment fees out of product costs, which makes break-even look lower than it really is.
Judging a campaign against break-even on the first order only, when repeat purchases would make a lower ROAS worth paying for.

Frequently Asked Questions

Divide 1 by your gross margin as a decimal. At a 50% margin that is 1 / 0.5 = 2x. At a 75% margin it is 1 / 0.75 = 1.33x. The higher your margin, the lower the ROAS you need to stop losing money.

No. Break-even means your ads cover product costs and nothing else. You still have to pay for overhead, your team and your tools, so a healthy target sits above break-even.
