Which smoothie bar expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful when fixed overhead stays separate from volume-driven spending. If base payroll is treated as fully variable, the model can understate the sales needed to cover the first operating year.

Expense	Cost	Break-Even Treatment	Common Mistake
Lease payment	Fixed	Include $1,500 per month in fixed overhead for the full Month 1 to Month 60 planning range.	Spreading it across orders and making low-volume months look safer than they are.
Commissary rent	Fixed	Include $800 per month as fixed overhead before calculating contribution margin.	Treating rent like a kitchen usage fee that rises only when sales rise.
Insurance	Fixed	Include $400 per month, made up of truck insurance and general liability insurance.	Leaving smaller policy costs outside break-even and understating monthly overhead.
Food ingredients	Variable	Apply 14.0% of revenue in the first year, falling to 13.0% by the fifth year.	Using a flat dollar amount and missing the direct link to order volume.
Beverage and packaging	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by the fifth year.	Forgetting cups, lids, straws, and bags when pricing each order.
Payment processing fees	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by the fifth year.	Modeling card fees as fixed even though they rise with sales.
Generator fuel and propane	Semi-variable	Model the usage-linked part at 1.0% of revenue in the first year, declining to 0.8% by the fifth year.	Ignoring the sales-linked burn rate during longer service days.
Payroll by FTE timing	Semi-fixed	Step payroll up as staffed capacity changes: owner, lead cook, service staff, assistant cook, and events manager.	Treating base payroll as fully variable and understating break-even revenue.

How does break-even change from a lean launch to a base plan and a full-staffed smoothie bar?

Scenario table

Lean sales sit close to break-even because fixed rent and labor take most of the margin. Base and full cases add cushion fast, but only if staffing rises with demand.

Planning assumptions only; actual break-even will move with sales mix, labor, and rent.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$18.4k	$3.7k	$14.8k	80.0%	-$0.1k	Near break-even; a small sales miss turns it negative.
Base launch case	$33.2k	$6.6k	$14.8k	80.0%	$11.8k	Clear cushion after fixed costs; this is the launch target.
Full staffing case	$45.3k	$8.9k	$17.6k	80.4%	$18.8k	Stronger cushion, but only if labor stays tied to demand.

What breaks the smoothie bar break-even plan?

Stress test

The base case clears break-even, but the cushion shrinks fast if traffic slips, ingredient waste rises, or staff and rent are added too early. A 20% sales drop or a 10% fixed-cost bump cuts the room for error hard.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$184,000	$147,000 cushion	Healthy, but not loose.
Revenue shortfall	Opening sales land 20% below plan.	$184,000	$81,000 cushion	Monthly sales near $22,000 still clear break-even, but the cushion shrinks.
Fixed-cost pressure	Fixed costs run 10% higher before volume builds.	$203,000	$129,000 cushion	Lease and staffing creep can eat the cushion fast.
Margin pressure	Variable expenses rise to 25% of revenue.	$197,000	$135,000 cushion	Waste, spoilage, and card fees push break-even up.
Combined pressure	Sales drop 20%, fixed costs rise 10%, and variable expenses rise to 25%.	$216,000	$49,000 cushion	This still clears break-even, but the room for error is thin.

What should you verify before signing the lease and buying the smoothie bar build-out?

Founder checklist

Don’t sign the lease or buy equipment until the traffic, margin, and cash reserve support Month 3 break-even. The model needs about 33 orders a day, and the first-year forecast works out to about $33.7K in monthly revenue.

1Daily orders33/day

Verify you can hold about 33 orders a day at an $18.89 average ticket, because that is the traffic needed to cover about $184K in break-even revenue.

2Overhead load$14.75K/mo

Verify monthly payroll and overhead stay near $14.75K before any added storefront rent, because fixed costs set the floor you must clear every month.

3Variable load80% CM

Keep food, packaging, processing, and fuel near 20% of sales, because that leaves an 80% contribution margin to cover payroll and overhead.

4Year 1 payroll$11.25K/mo

Verify the Year 1 team can handle 405 weekly orders with $11.25K a month in payroll, because labor gets heavier after Month 13 when the assistant cook starts.

5Cash need$794K

Confirm you have at least $794K in cash by Month 2, because that is the model's minimum cash point and a thin reserve makes the first ramp too fragile.

6Launch timingMonth 3

Confirm the $176.5K startup package is funded before you commit, because breakeven is modeled in Month 3 and payback takes 25 months.
