| Rent |
Fixed |
Use $12,000 per month from Month 1 through Month 60 before calculating break-even sales. |
Spreading rent as a sales percentage and understating the slow-month hurdle. |
| Utilities |
Fixed |
Use the modeled $2,000 per month unless a separate usage-based utility schedule is added. |
Flexing the full amount with orders when the model treats it as stable overhead. |
| Property Insurance |
Fixed |
Include $750 per month as recurring overhead in the operating break-even base. |
Leaving insurance out because it is not tied to daily covers. |
| Food & Beverage Ingredients |
Variable |
Apply 14.0% of sales in the first year, then use the modeled annual percentages. |
Using revenue as gross margin and forgetting ingredient drag on each sale. |
| Packaging & Supplies |
Variable |
Apply 1.0% of sales in the first year, stepping down as modeled over time. |
Treating bags, boxes, and supplies as fixed even though they rise with orders. |
| Marketing & Promotions |
Variable |
Apply 2.5% of sales in the first year because the model ties spend to revenue. |
Locking promotion spend as fixed and overstating contribution margin at higher sales. |
| Credit Card Processing Fees |
Variable |
Apply 1.0% of sales across all forecast years. |
Ignoring card fees on small transactions where pennies still reduce margin. |
| Approved Salaried Payroll |
Semi-fixed |
Use Year 1 payroll of $367,000 annually, then step up with FTE bands as staffing expands. |
Assuming payroll moves smoothly with sales instead of jumping when another full-time role is added. |
