Frequently asked questions

How does the ROAS calculator work?

It takes Revenue and Ad spend and derives ROAS (×) and Ad ROI from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

2 values: Revenue ($) and Ad spend ($). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Revenue = $10,000.00 and Ad spend = $2,500.00, the calculator returns ROAS (×) = 4 and Ad ROI = 300%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

When would I actually use this?

Before and after a campaign: turning a target into a daily budget, comparing two channels on the same basis, and deciding whether the return justifies continuing.

What is the most common mistake?

Judging ROAS without subtracting the cost of goods. A 3× return on ad spend is a loss whenever the margin is under a third — the ratio says nothing about profit on its own.

Where do the figures come from, and how current are they?

The formulas are the industry-standard ones every ad platform uses; the inputs come from your own reporting. Platforms differ in attribution window and in what counts as a conversion, so figures rarely reconcile exactly between them.
