Fee and profit calculators for Southeast Asian sellers

See what Etsy, Shopee, Lazada, TikTok Shop and Shopify take off one sale, then the profit that is left after your product, postage and packaging. Built in Malaysia by Wei Kang for The Seller Sheet. The maths stays on your device.

Is the calculator free?

Yes. It runs in your browser. There is no account, no payment, and no tracking script. The Seller Sheet’s paid spreadsheets are separate, on Gumroad, if you want a tracker for every order rather than one sum.

Are the fee rates official?

Each line is marked. Official means the figure was read on the marketplace’s own page. Secondary source means a transcription of a table the platform published as an image or PDF. Unverified means the rate is a placeholder or a guess and you should replace it with your Seller Centre figure.

Do you store what I type?

No. Prices and costs are not sent to a server. If you edit the exchange table, those rates stay in this browser only. Closing the tab does not upload them.

Who publishes this?

Wei Kang, in Malaysia, under the shop name The Seller Sheet. The Gumroad shop is soowk.gumroad.com, the Etsy shop is soowkstore, and the blog is soowkstore.blogspot.com.
