How this calculator works
The calculator walks one ad budget through the paid funnel: impressions × click-through rate gives clicks; clicks × conversion rate gives conversions; conversions × average order value gives revenue. From there it derives the three figures that matter — return on ad spend (revenue ÷ spend), cost per click, and cost per acquisition — plus a profitability verdict against break-even.
Use it in two directions. Before a campaign, model whether the rates you would need are plausible: if profitability requires a 5% click-through rate, the plan is the problem, not the execution. After a campaign, enter blended numbers from your own analytics rather than platform-reported conversions, which often count the same purchase across several attribution windows.
What good looks like: break-even is not 1x. A practical rule of thumb is that break-even ROAS ≈ 1 ÷ gross margin, so a 50%-margin product breaks even near 2x and usually targets 3–4x. The verdict bands reflect that — under 1x you lose money on revenue alone; between 1x and 3x spend is covered but margins thin once product and fulfillment costs count; 3x and above is commonly worth scaling. The levers, in order of typical impact: conversion rate (the landing page), average order value (the offer), then click-through rate, which mostly lowers your effective CPC.
Frequently asked questions
What is a good ROAS?
It depends on your margin. A useful rule of thumb: break-even ROAS is roughly 1 divided by gross margin, so a product with 50% margin breaks even near 2x and usually targets 3–4x. Pure break-even on revenue is 1x, but that ignores every other cost.
How is ROAS different from ROI?
ROAS is revenue divided by ad spend and ignores all other costs. ROI counts profit after costs. A campaign can post a strong ROAS and still lose money on a thin-margin product.
Why does my ad platform report a different ROAS?
Attribution windows, view-through conversions, and double counting across platforms all inflate platform-reported numbers. Model with blended figures from your own analytics — total ad spend against total tracked revenue.
Which input should I improve first?
In the formula, conversion rate and average order value multiply directly into revenue, so the landing page and the offer are usually the biggest levers. CTR mostly lowers your effective cost per click.
