Free / ROAS calculator
Where does the next £1,000 go?
Blended ROAS tells you how the average pound did. This tells you whether the next one is worth spending: break-even, profit after ad spend, the marginal ROAS the increment needs, and how long until you have enough conversions to trust the answer.

Break-even ROAS, profit, and what the next £1,000 has to earn.
HOW THE MATHS WORKS
- Break-even ROAS
- One divided by gross margin. At 50% margin every pound of ad spend needs two pounds of revenue back before anything is earned.
- Marginal, not blended
- The next pound never earns what the first did. The table applies three decay rates to the extra spend and checks each against break-even.
- Confidence gate
- Fifty conversions inside seven days before a budget change, and never more than twenty per cent at once — the same rule ROAScal uses before it recommends a move.
