How Squarespace Commerce fees actually work
Squarespace Business plan charges 3% transaction fee on top of payment processing; Commerce plans waive that fee. Every seller calculator that skips one of these layers will overstate your profit — sometimes by 10–20 percentage points of margin. This tool applies the full stack: Business plan: 3% transaction fee. Commerce plans: 0%. Stripe 2.9% + 30¢ always. If your accountant tells you your margin is lower than what a marketplace listing tool shows, this is usually why.
Who sells well on Squarespace Commerce
Designers, creatives, brand-led boutiques. Sellers who match those categories tend to see the strongest unit economics here because their cost per acquisition stays low and the platform's organic traffic does the heavy lifting. If you sell outside those lanes you can still succeed, but you'll need to budget more for ads and own audience.
How shoppers find products on Squarespace Commerce
SEO + Squarespace email + own social. That changes how you should price: in search-driven marketplaces, undercutting competitors by 5% can dramatically lift conversion and offset your margin loss with volume. In curated or recommendation-driven platforms, premium pricing with great photos and reviews often outperforms a price war.
Using this calculator with your real data
Pull last 30 days of orders from your Squarespace Commerce dashboard. Average the item price, shipping charged, and your real COGS (don't forget returns and damaged-in-transit). Punch them in. If your calculated net profit doesn't match what hit your bank account, the gap is usually returns, refund retention fees, currency conversion, or a category-specific fee. Adjust the misc cost field to model that.

Frequently asked questions
What fees does Squarespace Commerce charge sellers?
Business plan: 3% transaction fee. Commerce plans: 0%. Stripe 2.9% + 30¢ always.
Does this calculator include taxes?
No — sales tax / VAT / GST is collected from the buyer and remitted (in most cases) by Squarespace Commerce on your behalf, so it doesn't hit your margin. Add income tax on your net profit separately at your country's rate.
Are Squarespace Commerce fees negotiable?
For most sellers, no — they're set by the platform. High-volume sellers, brand-registered sellers, or enterprise accounts sometimes negotiate reduced commissions or waived fees, but you typically need to clear $250K+/yr in gross sales to start that conversation.
How accurate is this calculator?
It uses Squarespace Commerce's publicly-published rate card as of 2026. Category-specific commissions, returns, refund retention fees, and currency conversion can adjust your real net by 1–3 percentage points. Always cross-check against your monthly statement.
What's a healthy net margin on Squarespace Commerce?
For most product categories on Squarespace Commerce, a 20–30% net margin after all fees, COGS, ads and returns is healthy. Below 15% you'll struggle to absorb returns and reinvest in inventory; above 35% you're either underpriced for the platform or you have a moat worth protecting.
