Frequently Asked Questions

What is the Seller Tools hub?
It's the full index of every calculator on Marginory, grouped by platform: platform-agnostic tools, Etsy, print-on-demand, Shopify, TikTok Shop, and eBay. Use it to jump straight to a specific calculator or browse everything one platform offers.
Which platform has the lowest fees?
It varies by volume and product. TikTok Shop's flat 6% fee is often the cheapest per order. Etsy runs roughly 9-10%+ combined before Offsite Ads. eBay is about 13.6% FVF plus a per-order fee. Shopify has a monthly subscription but lower per-order processing at scale. Check the comparison pages for numbers specific to your product.
How do I compare Etsy vs Shopify vs TikTok Shop costs?
Use the platform comparison pages under /comparisons — they calculate two platforms side by side on the same inputs so you see an exact profit difference rather than generic percentages.
Are all these calculators free?
Yes, every calculator on this page and throughout the site is free with no account or sign-up required.
I only sell on one platform — do I need the Core Seller Calculators too?
The Core Seller Calculators (profit, pricing, markup, margin, break-even, ROAS) are platform-agnostic and useful for quick, generic math. For exact numbers on a specific platform's actual fee structure, use that platform's dedicated tools instead — they account for fees the generic calculators don't.
How often are the fee rates in these calculators updated?
We verify rates against each platform's official fee documentation regularly. TikTok Shop and Shopify promotional rates change more frequently than Etsy's or eBay's fee schedules, so always check the "last verified" note on the tool you're using.
