Reading the verdict

Your 3.00x ROAS is comfortably above the 1.82x your margin requires. The harder question is how much further you can push spend before the curve flattens.

How ROAS is calculated

The formula.

ROAS = revenue from ads ÷ ad spend. Expressed as a multiple. A $30,000 return on $10,000 of spend is a 3.0x ROAS.

The number ignores cost of goods, fulfilment, and overhead. It tells you what came back from the platforms, not what hit the bank account.

Break-even ROAS.

Calculated as 1 ÷ gross margin. A business running 50 percent gross margin needs at least a 2.0x ROAS to clear cost of goods. Anything less means every order loses money.

The break-even number is what most agency dashboards quietly skip. Without it, ROAS targets are arbitrary.

Frequently asked

Five questions about ROAS.

What is ROAS and how do I calculate it?

ROAS (Return on Ad Spend) is revenue from ads divided by ad spend. A $30,000 return on $10,000 of ad spend is a 3.0x ROAS. The calculator on this page does the maths and overlays your break-even ROAS so you can see whether the number is genuinely profitable.

What is a good ROAS in 2026?

There is no universal good ROAS. The number that matters is your break-even ROAS, calculated from your gross margin: 1 ÷ gross margin. A 50 percent margin business breaks even at 2.0x. A 30 percent margin business breaks even at roughly 3.3x. Anything below break-even loses money on every order.

What is break-even ROAS?

The lowest ROAS that covers your gross margin and overhead. The calculator returns this alongside your actual ROAS so you can see the gap. Above it, you scale; below it, the channel is a cost centre.

Why does my ROAS reported by Meta differ from the bank?

Three common reasons: cross-platform deduplication is double-counting; view-through windows are inflating attribution; or the platform conversion event is firing on the /thank-you page-view rather than the actual order. A two-week tracking audit usually closes the gap to within five percent.

What if my ROAS is below break-even but the channel feels essential?

It usually means one of two things: the attribution is misallocated (the channel is genuinely contributing but the credit is going elsewhere), or the channel is a brand cost dressed up as a performance channel. An incrementality test will tell you which it is.
