| Rent |
Fixed |
Include the $3,500 monthly rent in fixed overhead from Month 1 through Month 60. |
Treating rent as lower on slow weekdays, which understates the sales needed to break even. |
| Utilities |
Semi-fixed |
Model the $800 monthly base, then watch for step-ups as oven use and service volume rise. |
Leaving utilities flat forever even as covers grow from the first year to later years. |
| Ingredients |
Variable |
Apply ingredients as a revenue-linked percentage, starting at 12.0% in the first year. |
Putting ingredients in fixed overhead, which hides margin pressure when orders increase. |
| Packaging Supplies |
Variable |
Apply packaging as a sales-linked expense, starting at 2.0% in the first year. |
Ignoring packaging on delivery and takeout orders because it looks small per ticket. |
| Delivery Platform Fees |
Variable |
Apply fees as a percentage of sales, starting at 3.0% in the first year. |
Using one blended margin for dine-in and delivery, which overstates contribution. |
| Barista/Server Wages |
Semi-variable |
Use the first-year 2.0 FTE base, then increase staffing as volume rises to 4.0 FTE by the fifth year. |
Treating all hourly coverage as fixed, then missing the labor needed for busier weekends. |
| Kitchen Assistant Wages |
Semi-variable |
Start with 1.0 FTE in the first year and scale toward 2.0 FTE by the fifth year as production rises. |
Holding kitchen support flat while forecast covers grow, which makes labor margins look too good. |
| Head Baker Wages |
Fixed |
Include the $55,000 annual salary as recurring overhead across the planning period. |
Allocating the salary only to busy days, which understates the monthly break-even base. |
