The example values are placeholders to show how it works, not data from a real store.

The problem

Many store owners judge ads by a ROAS number someone else told them was good. The right target depends on your own margins: a ROAS of 2 can be very profitable for one store and loss-making for another.

My role

Designed and built by me. It runs entirely in your browser; nothing you type is sent anywhere.

Approach

Asked only for numbers an owner already knows: price, product cost, delivery cost, other per-order costs.
Calculated profit per order before ads, then the break-even ROAS and cost per purchase.
Added a target-margin input, so the tool also shows the ROAS you need to keep a chosen profit.
Explained each result in one sentence so it's useful without a marketing background.
