Break-even ROAS Calculator

A 3× ROAS is excellent for one business and a slow bankruptcy for another. The difference is margin. Enter your price and your costs to find the exact ROAS below which every additional dinar of ad spend loses money.

The most useful number here is often the last one: your maximum cost per customer. It converts an abstract ratio into a bidding instruction you can actually give — the cost per purchase above which you turn the campaign off.

Frequently asked questions

Why isn't break-even just 1.0× ROAS?+

Because 1.0× only covers the ad spend, not the product. If a 25 KWD order costs you 12 KWD to fulfil, only 13 KWD is available to pay for advertising — so you break even at roughly 1.9×, not 1.0×.

What counts as a good ROAS?+

It depends on your margins. Work out your break-even ROAS from your costs, then aim comfortably above it. Anything under break-even loses money even if it looks busy.

Are the amounts in Kuwaiti dinars?+

Yes — every currency field is KWD. The maths is currency-agnostic, so you can use it with any currency as long as you stay consistent across the fields.

Is this tool really free? Do I need an account?+

Free, and no account. Everything runs in your browser — we never see your numbers unless you press save to create a shareable link.
