How to Calculate Product Profit Margin

Gross margin trims revenue by COGS; Shopify-style tools add shipping and payments—stay consistent whichever path you choose.

Gross first

Revenue minus variable product cost before rent and salaries.

Exclude costs you purposely treat downstream.

Fold fees that scale with orders

Processors, refunds, fulfillment lines often behave like gross costs for pricing decisions—even if bookkeeping stores them separately.

Plug ads after margin is sane

Use ROAS and break-even ROAS once SKU margin is truthful—not fantasized.
