Practical questions on this topic
What is a good ROAS for a store?
It depends on your margin and variable costs. A universal target would ignore the economics of your products.
How is break-even ROAS calculated?
Divide attributable net revenue per order by contribution before ads. The result is a threshold under the entered cost assumptions.
Why can a high ROAS still lose money?
Sourcing, fulfillment, fees and returns can consume most of the revenue even when ads report a high sales multiple.
How can I estimate a maximum CPC?
Multiply break-even CPA by expected conversion rate as a decimal. This is a mathematical ceiling, not a guaranteed bid.
How many orders cover fixed costs?
Divide fixed costs by positive contribution per order and round up. When CPA is known, this tool uses contribution after ads.
Frequently asked questions
Can I use it for Google Ads?
Yes, with consistent net revenue, costs and attributed orders.
Does it work for Meta Ads?
Yes. The math is channel-independent; the inputs must reflect your campaign.
What if contribution is negative?
More orders alone cannot create break-even while each order has negative contribution.
Can I compare scenarios?
Yes. Save local results and vary spend, order count or costs.
