Food Cost Variance & Root Cause Analysis
Diagnose food cost variances and pinpoint root causes in minutes
What You Can Do
You can analyze actual versus standard food costs to identify exactly where variance is occurring—whether it's portion creep, supplier price hikes, waste, or other factors. Claude generates a structured root cause analysis, categorizes the variance drivers, and recommends targeted corrective actions ranked by impact and ease of implementation. This helps you recover margins without guessing.
Features
Automatically classifies cost variances by root cause: portion control drift, supplier pricing, product mix changes, waste/spoilage, yield loss, theft/pilferage, or recipe changes.
Traces variance back to specific operational factors using your actual vs. standard cost data, inventory movements, and purchase records.
Recommends fixes ranked by dollar impact and implementation effort—from quick wins (portion control tightening) to systematic changes (supplier renegotiation).
Identifies spoilage patterns, trim waste, and cooking yield losses that inflate food costs, with quantified impact on margin.
Compares supplier prices across delivery periods and flags unusual spikes or drift that signal negotiation opportunities.
Shows which menu items are affected most by the variance and how cost changes affect overall contribution margin per dish.
Plots variance over time to detect seasonal patterns, creeping inefficiencies, or the impact of past corrective actions.
Example Output
Variance Summary:
- Total Variance: +$3,240 (6.2% unfavorable)
- Protein costs: +$1,890 (8.1%) — primary driver
- Produce costs: +$880 (5.2%) — seasonal spike
- Prepared items: -$530 (favorable)
Root Causes Identified:
- Supplier price increase on beef (+$0.85/lb) — effective Oct 1
- Portion creep in steak entree (+0.5 oz average)
- Waste rate on produce up to 8.3% (vs. 6% standard)
Corrective Actions (by impact):
- Renegotiate beef contract — recover $1,200/month, 2-week effort
- Portion retraining — recover $400/month, immediate
- Supplier swap for produce — pilot new vendor, recover $300/month, 3-week setup
