Is this calculator specific to Shopify?

The math is ecommerce-specific and works especially well for Shopify stores because it includes the costs Shopify merchants usually need to model: COGS, payment fees, shipping, returns, ad spend, inventory, conversion rate, or repeat purchases depending on the tool.

Should I use gross margin or contribution margin?

Use contribution margin when you are making advertising, discount, or growth decisions. Gross margin is useful, but contribution margin is stricter because it accounts for variable costs like payment fees, fulfillment, shipping, returns, and app costs.

Why does the tool use default values?

Defaults make the calculator useful immediately and show the shape of the result before you enter your own numbers. Replace them with your store's actual numbers before making a final decision.

About this tool

What this free tool calculates

Use this when attribution is noisy. It answers whether total paid spend is profitable against total tracked revenue and contribution margin.

How to use the result

Blended ROAS is total revenue divided by total ad spend. Profit after ads is revenue times contribution margin minus total ad spend.

Use blended ROAS as the executive view, then diagnose channel-level problems with the Meta, TikTok, and Google Shopping calculators.
