A convenience store can have a steady stream of customers and still net 2-6% — because the diagnosis is not traffic, it is category mix and shrink. Volume without margin is just a busy way to lose money slowly.
The c-store diagnostic dashboard
| Metric | Healthy | Red line |
|---|---|---|
| Gross margin | 25-35% | below 25% |
| Labor % of revenue | 10-15% | above 15% |

| Shrink % of sales | 1-3% | above 3% |
| Net profit | 2-6% | below 2% |
Category margins — diagnose the mix
| Category | Gross margin |
|---|---|
| Soda / fountain | ~85% |
| Packaged beverages | 60-65% |
| Snacks | ~40% |
| Fresh food / coffee | 34-60% |
| Tobacco | 10-15% |
| Lottery | 1-2% |
A store that leans on tobacco and lottery for volume is trading margin for foot traffic. Building the cooler and fresh-food mix is the highest-leverage fix available without a lease change.
Shrink hits net directly: at 1-3% of sales, shrink comes out of a 2-6% net. Tighten cash handling, cooler-date rotation, and POS controls before chasing more traffic.
