Calculation
Ad revenue ÷ ad spend = ROAS
COST-AWARE REVIEW
READY FOR INPUT
ROAS alone does not establish profitability or justify scaling. Compare it with your entered order costs and attribution assumptions in the planning section below.
Net Revenue Verification
Attributed revenue should exclude sales taxes, shipping surcharges, and estimated return reserves.
Unit Economics Interlock
Cross-reference this campaign multiple with Card 02's Break-even floor to verify actual dollar contribution.

Break-even target
Enter every cost; use 0 where none applies.

Variable-cost break-even allowance per order
Calculations
Product cost + shipping + transaction fee + other cost = total non-ad cost
Selling price − total non-ad cost = maximum CPA
Selling price ÷ maximum CPA = break-even ROAS
Use one currency throughout. Currency selection changes labels only, not amounts. The calculators work independently. Order revenue should reflect the discount, refund and tax basis you chose. Shipping collected must be treated consistently. Break-even covers only the costs entered, not automatically overhead or net profit. Understand the cost model.
Make room for what needs to remain.
Turn the order economics above into an explicit contribution target.
Use the selected currency. Enter 0 to plan for variable-cost break-even. Retained contribution must still cover any excluded overhead or taxes.

The arithmetic, made visible
Three numbers. Different questions.
ROAS
Revenue ÷ ad spend
Illustrative: $4,800 ÷ $1,200 = 4×, or 400%. This measures credited revenue, before other costs.
Maximum CPA
Order revenue − non-ad costs
Illustrative: $100 − ($40 + $7 + $3 + $2) = $48 available for acquisition before excluded costs.
Break-even ROAS
Order revenue ÷ maximum CPA
Illustrative: $100 ÷ $48 = 2.0833…×. This is a floor for the modeled costs, not a profit target.
Before you act
Common calculator questions
Is 4× ROAS good?
It depends on contribution margin, overhead and the goal of the campaign. A $100 order with $80 of non-ad costs loses $5 when advertising costs $25, even though its ROAS is 4×.
Why is my break-even result blank?
Enter positive order revenue and all four cost fields. Enter 0 for a cost that does not apply. Placeholders are examples, not entered values.
Can I use a different currency?
Yes. Use the same currency for every amount you compare. Select one of the display currencies above; this changes formatting only and performs no exchange-rate conversion.
Why is there no universal target?
Your target depends on costs and the contribution you need to retain. Use the margin-based target calculator in our guides to make those assumptions explicit.
Does MetricClue receive my campaign numbers?
Calculator inputs and results are processed locally by the page. No account, upload or server-side calculation is used. Hosting requests and any email you send are separate; see our privacy page.
Does ROAS prove the advertising caused the sales?
No. Attribution assigns credit under reporting rules. Measuring additional sales caused by ads requires a credible comparison, such as an appropriately designed experiment.
