How to Calculate and Control Prime Cost in Your Canadian Restaurant
Prime cost — total COGS plus labour — is the single most important number for an independent restaurant. Here's how to calculate it, set targets, and keep it under 60% of sales.

What Is Prime Cost?
Prime cost is the sum of your total Cost of Goods Sold (COGS) and your total labour cost. For most independent Canadian restaurants, a healthy prime cost sits between 55% and 60% of total sales. Anything above 65% means you're likely operating at a loss once rent, utilities, and other fixed costs are paid.
How to Calculate It
Prime Cost = Beginning Inventory + Purchases − Ending Inventory + Total Labour Cost
Total labour includes wages, employer CPP/EI contributions, WSIB/WCB premiums, and benefits. Don't forget to include salaried managers and owner-operator pay if you draw a wage.
Set a Target and Track Daily
The biggest mistake independent operators make is reviewing prime cost only at month-end. By then, the damage is done. Track your food cost percentage and labour percentage daily against a target, so you can course-correct mid-week.
Foodie Run calculates your prime cost automatically from your daily sales and expense entries — no spreadsheets required.
Quick Wins
- Recipe costing: Cost every menu item to a penny and flag items above your target food cost %.
- Schedule to sales: Build your labour schedule against projected sales, not last week's habit.
- Track wastage: Log every wasted item — it's hidden COGS that erodes margin.
Start by tracking prime cost daily for two weeks. You'll spot the leaks fast.
