How the Target ROAS Matrix works

The matrix multiplies ten ad spend levels by ten ROAS targets and shows the revenue and profit of every combination, so you can see where scaling starts to pay before you commit budget.

Each profit cell takes revenue, subtracts ad spend, removes the VAT share contained in gross revenue (revenue x rate / (100 + rate)) and subtracts COGS as a percentage of revenue. VAT is treated as included in your prices, which is the standard for EU ecommerce.

Green cells are your strongest scenarios, neutral cells barely clear zero and red cells lose money. If your current ROAS sits in a thin band, the matrix shows how much spend that band can carry.
