How to use it
- Use your real average order value from Shopify, after discounts.
- Include every variable cost: product, pick and pack, postage, packaging and payment fees. Leave out fixed costs like rent and salaries.
- Compare break-even ROAS to your Ads Manager ROAS. If you're below it, scaling spend scales losses.
- Do it per product or bundle. A $35 single item and a $75 bundle have very different break-even CPAs. Lead your ads with the one that can afford acquisition.
Frequently asked questions
How do you calculate break-even ROAS?
Break-even ROAS = average order value divided by contribution per order before ads. Contribution is order value plus shipping charged, minus product cost, postage, packing, payment fees and returns.
What is break-even CPA?
Break-even CPA is the most you can pay in advertising to win one order without losing money. It equals your contribution per order before ads.
Why is my ROAS high but I'm not making money?
ROAS ignores product, shipping and fee costs. If your ROAS is below break-even ROAS, every order loses money even when ROAS looks healthy.
