Is the Shopify profit margin calculator accurate?

Yes — Shopify's free margin calculator computes gross margin and markup correctly from cost and price. It is a solid quick check. What it does not cover is the rest of the decision: shipping and fulfillment cost, marketing cost per order, return rates, and whether the resulting margin can support your ad spend.

What does Clear Margins add over Shopify's free calculators?

Clear Margins models the full unit economics — COGS, shipping, marketing cost, and target margin together — then connects the result to your break-even ROAS, discount break-even volume, return-rate impact, and reorder points. Every result includes an operator benchmark and a recommended next action, and paid plans add saved scenario history and client-ready exports.

Do I need a Shopify store to use either tool?

No. Both Shopify's calculators and Clear Margins are free on the web with no store or account required. Clear Margins works the same whether you sell on Shopify, Amazon, WooCommerce, or direct.

Tool comparison

Clear Margins vs. Shopify's Free Calculators

Shopify's free tools answer “what is my margin?” Clear Margins answers the question behind it: “can this margin support my ad spend, discounts, and return rate — and what should I change if not?”

When to use each

Use Clear Margins when

Your real margin includes shipping, fulfillment, and marketing cost per order
You're deciding whether an ad campaign or discount is actually profitable
Returns eat into your margin and you want them in the math
You want each result benchmarked with a recommended next action
You sell on Amazon, WooCommerce, or direct — not just Shopify

Use Shopify's tools when

You need a fast gross-margin check from just cost and price
You're setting up a new store and want name, logo, and slogan generators
You already live in the Shopify admin and want tools in the same ecosystem

Why “margin” alone misleads e-commerce operators

A product with a 60% gross margin on cost and price can still lose money once you subtract $8 shipping, $12 marketing cost per order, and a 15% return rate. Single-input margin calculators are correct but incomplete. The Clear Margins margin calculator includes shipping and marketing per unit, and the returns calculator shows what your return rate does to contribution profit — before you scale spend.

Run your full unit economics — no account or store required.
