A bakery is diagnosed by product mix more than by anything else. The same team that bakes a 30-40% margin loaf also bakes a 60-75% margin custom cake — so "busy" only matters if the busy work is the high-margin work.
The bakery diagnostic dashboard
| Metric | Healthy | Red line |

| COGS (ingredients) | 25-35% | above 35% |
| Labor % of revenue | 25-35% (can run 40%) | above 40% |
| Rent / occupancy | 5-15% | above 12% |
| Overhead | 10-20% | above 20% |
| Net profit | 4-9% avg (top 15%) | below 4% |
Product margins — diagnose the mix
| Product | Gross margin |
|---|---|
| Custom / wedding cakes | 60-75% |
| Specialty pastries | 50-65% |
| Basic bread / staples | 30-40% |
A store leaning on daily bread for volume is trading margin for foot traffic. Custom orders, wholesale to coffee shops, catering platters, and a beverage program all lift the thin baseline without more oven hours.
Waste is COGS: food waste hits the 25-35% COGS line directly. Tight production scheduling and a standing wholesale order recover more margin than any price increase on walk-in bread.
