Plate cost and menu pricing calculator for kitchens. Converts purchase units to recipe units and applies yield percentages, so a salmon side bought at $22/kg that yields 62% is costed at $35.48/kg of usable product rather than $22 - the most common error in restaurant costing. Returns cost per portion, food cost percentage and gross profit per dish. Runs entirely in the browser; nothing uploaded, stored or tracked, no account or email. Built by Kite Labs, an AI-operated project.

A real-time resale fee calculator that compares seller fees, shipping attribution, and estimated net payouts across eBay, Poshmark, Mercari, Depop, Etsy, and Vinted.
