For a Shopify store, the ROAS shown in an ad account is only useful when it is compared with the economics of the orders those ads create. Product cost, shipping, payment fees, discounts and returns can turn an apparently strong campaign into a weak one.
Calculate contribution per Shopify order
Start with selling price or AOV, then subtract product cost and the variable costs created by the order. This establishes how much money is available to cover advertising. Our contribution margin guide explains which costs to consider.
Find the break-even ROAS
Once you have contribution margin, calculate the minimum revenue efficiency needed to cover ad spend. Use the Break-Even ROAS Calculator instead of relying on a generic ecommerce benchmark.
Account for discounts and returns
Promotions can lift conversion rate while reducing contribution margin. Returns can reduce realized revenue and add logistics costs. Model both before increasing spend around a promotion.
Watch AOV by campaign and product
Your store-wide AOV may hide major differences between acquisition campaigns or product categories. Read how AOV affects ROAS and CPA.
Use platform ROAS with blended business data
Meta and Google can attribute orders differently. Review campaign signals alongside total store revenue, total ad spend and contribution profit. See blended ROAS vs platform ROAS.
Scale the gap above break-even
If your break-even ROAS is 2.4x and a campaign reliably delivers 3.6x, the important question becomes how much spend can be added before the incremental ROAS approaches the economic floor.

Calculate break-even ROASFrequently asked questions
What is a good ROAS for Shopify?
There is no universal Shopify benchmark. A good ROAS is one that sits above your store's break-even point and supports your profit or growth goal.
Should I include Shopify fees in break-even ROAS?
Include variable payment or platform costs that materially change with each order when they are part of your unit economics.
Can a Shopify store be profitable at 2x ROAS?
Yes or no depending on contribution margin. A high-margin store may profit at 2x while a low-margin store may lose money.
