Editorial interest 78/100 Selection signal · not a rating of the site

A free calculator compares estimated profit, fees, and minimum viable prices across Shopee, Mercado Livre, and TikTok Shop.

Landing page captured for the 2026-10-29 issue.

For: Brazilian marketplace sellers comparing product margins
Worth noticing: It distinguishes CPF account conditions, including a 450-orders-in-90-days threshold, and lets sellers adjust channel-specific fees manually.

Field notes

The form separates shared seller costs from channel-specific conditions: examples include Shopee account type, Mercado Livre listing type and category commission, and TikTok Shop's shipping-fee program. Sellers can enter an effective tax rate, but the page says this is an estimate rather than an official tax calculation and advises validation with an accountant. It also says saved simulations remain in the browser.
