Why Most ROAS Calculators Get It Wrong

A 4x ROAS sounds great - until you realise your margins are only 20%, which means your break-even ROAS is 5x. You're actually losing money. This calculator factors in your real product margins to show you the numbers that matter:

Break-even ROAS - The minimum return you need to cover product costs and ad spend. Below this, every sale loses money.
Target ROAS - The return needed to hit your desired profit margin after all costs.
Headroom - How far above (or below) break-even your current performance sits. This tells you whether you can scale spend or need to optimise.

How to Use This for Client Reporting

When presenting ROAS data to clients or stakeholders, context is everything. "4.1x ROAS" means nothing without knowing the margin. With this calculator, you can show: "Your break-even is 2.5x, your profit target requires 3.8x, and you're at 4.1x - you have 64% headroom above break-even." That's an answer that builds confidence and justifies scaling spend.
