Store Health & Diagnosis 2026: Is Your Open Store Sustainable?
A plain-English operating-store framework for U.S. retail, cafe, and food businesses. Separate paper profit from cash, find your break-even gap, audit the hidden costs eroding margin, and track the KPIs that decide survival — built around one free flagship calculator and sourced benchmarks.
Diagnose With Four Numbers
Paper profit lies. These four tell you the truth about whether the store can keep going.
| Number | What it tells you | How to get it |
|---|---|---|
| True net | Profit after employer tax and owner draw | Store Health Check |
| Break-even gap | Actual revenue vs required revenue | Actual − (fixed ÷ contribution ratio) |
| Cash runway | Months until cash runs out | Cash on hand ÷ monthly burn |
| Hidden-cost total | Card fees, employer tax, NNN, shrink, platform | Health Check audit |

Ranges That Define a Healthy Store
Educational estimates from U.S. small-business research (retrieved 2026-08-13).
| Metric | Healthy range | Red line |
|---|---|---|
| Gross margin | 60-70% (retail & food) | Below 50% |
| Net profit % | 5-15% retail; 3-10% restaurant | Below 3% |
| Rent % of sales | 6-10% | Above 10-12% |
| Labor % of sales | 10-20% retail; 25-35% restaurant | Above 35-45% |
| COGS % | 25-35% food; 50-70% retail goods | Above segment norm |
| Inventory turnover | 4-12×/yr (varies by type) | Below 4× (dead stock) |
| Survival rate | ~80% reach yr 1; ~51% reach yr 5 | Cash-flow, not demand, is the usual cause of failure |
Note: The "90% of restaurants fail" claim is a myth. BLS data shows ~20% of new businesses close in year 1 and ~49% by year 5; retail-trade and food-service are near the average. Plan for cash-flow risk, not doom.
How to Diagnose Your Store
Six steps that turn your P&L into a clear verdict.
- Enter real revenue and costs. Use actuals, not hopes — the Health Check reads your true numbers.
- Fold in employer payroll tax. Add ~15-25% on wages so profit is real, not cosmetic.
- Include your owner draw. "Profitable without my salary" is not sustainable; model the wage you must take.
- Read the break-even gap. If actual revenue sits near required revenue, you have no cushion.
- Run the hidden-cost audit. Card fees, NNN load, shrinkage, and platform fees explain most margin leaks.
- Track the KPIs monthly. Gross margin, net %, rent %, labor %, turnover, and break-even — watch for red lines.
Nine Things Eroding Open-Store Profit
1. Spending collected sales tax
It is pass-through. A missed remittance creates penalties and a cash hole.
2. Ignoring employer payroll tax
Wages are not the full cost — FICA, SUTA, FUTA, and workers' comp add 15-25%.
3. Treating base rent as occupancy
NNN leases add CAM, insurance, and tax on top. Model the full number.
4. Skipping the owner's wage
If you must pay yourself, include it. "Profitable without my salary" is not sustainable.
5. No daily minimum revenue target
Without a daily floor, you cannot tell whether a slow day is harmless or fatal.
6. Thin margin, no buffer
Under ~5% net margin, one slow month or cost spike wipes out profit.
7. Platform fees piling on
Selling via Etsy/Amazon/delivery adds 8-15% on top of card fees.
8. Dead inventory
Turnover below 4× ties cash in stock that never sells.
9. No cash buffer
Under 3 months reserve, a single shock becomes an existential event.

Bar/TavernFrequently Asked Questions
Short answers to the questions we hear most about store diagnosis.
Usually a hidden-cost leak or a timing gap: you are spending collected sales tax, ignoring employer payroll tax, or your fixed cost is too high a share of revenue. The Store Health Check maps these and shows your true net and cash runway.
True net (after employer tax and owner draw), break-even gap (actual vs required revenue), cash runway (months of reserve), and the hidden-cost total. All four come from the Store Health Check on your real numbers.
Gross margin and break-even revenue. Margin tells you what each sale keeps; break-even tells you the sales floor you must clear. The KPI Benchmark Board shows healthy ranges and red lines for both.
Three to six months of operating expenses. Below that, a single slow month or cost spike becomes an existential event.
Break-even is one input. The diagnosis goes further: it separates paper profit from cash, folds employer tax and owner draw into cost, and prints a hidden-cost audit you can act on.
