The Restaurant Owner's Cash Flow Survival Guide: 5 Numbers You Must Track Weekly

I've watched restaurants with packed dining rooms go under because the owner didn't know their food cost percentage until it was too late. Revenue on the register doesn't mean cash in the bank.

The 5 Numbers Every Restaurant Owner Must Track Weekly

1. Food Cost Percentage — Total food purchases ÷ total food sales. Target: 28–32% for full-service, 25–28% for fast casual. If this drifts above 35%, you're losing money on every plate.
2. Labor Cost Percentage — Total labor (wages + taxes + benefits) ÷ total revenue. Target: 25–35% depending on concept. Colorado's rising minimum wage makes this number critical.
3. Prime Cost — Food cost + labor cost. This is the single most important number. If prime cost exceeds 65%, profitability is nearly impossible regardless of revenue.
4. Cash on Hand — Actual bank balance after all pending transactions. Restaurants need 2–4 weeks of operating expenses in reserve. Most owners guess — you need to know.
5. Accounts Payable Aging — What you owe vendors and when. Falling behind on Sysco or US Foods doesn't just hurt relationships — it triggers COD terms that crush cash flow.

Why Weekly — Not Monthly

Monthly bookkeeping is autopsy reporting. By the time you see February's numbers in March, you've already made March's purchasing decisions blind. Weekly tracking catches a food cost spike on Tuesday, not on the 15th when your vendor statement arrives.

Real Results: Thornton Family Restaurant

A family-owned restaurant doing $62,000/month in revenue was consistently short on payroll despite full dining rooms. We implemented weekly prime cost tracking and discovered their food cost had crept to 38% — driven by portion drift and vendor price increases nobody was monitoring. Within 60 days of weekly tracking and vendor renegotiation, food cost dropped to 31% and they recovered $4,200/month in margin.
