Hey PH, Brock here. I spent 5 years as General Manager of a bar in San Bernardino County (Cosmos Taverna). Writing schedules, pulling inventory, costing recipes, training bartenders on pour cost, running tip pools. Every "free" restaurant calculator I tried wanted my email and a follow-up call before showing the math. I just wanted to calculate food cost percentage with inventory inputs. Built one. Then a labor calc. Then 14 more. What I tried to get right that the SaaS calculators usually don't: • Recipe cost handles yield loss (tenderloin runs about 30% trim. Most calcs ignore this and understate plate cost by a third) • Food cost does true COGS from inventory (Opening + Purchases minus Closing), not just purchases • Tip pool has FLSA section 3(m)(2)(B) compliance flags built in. BOH-in-pool only legal if no tip credit is taken. That is the part that gets operators sued • Labor cost separates wages from full burden (taxes + benefits + workers comp). Most operators undercount labor by 15 to 25% because they only look at wages • Math shown under every result. If you do not trust the number, you can verify by hand Stack: Astro + Cloudflare Workers. Static HTML. No React. No email capture. No remarketing pixel. GA4 for aggregate page counts only. Free. Nothing paywalled. No signup. Looking for feedback from operators (chefs, bar managers, owners, GMs) and from builders on what is missing or wrong.
