Which sandwich shop expenses are fixed, variable, semi-variable, or semi-fixed at break-even?

Cost classification

Break-even works only if each expense follows its true driver. Treat ingredients and commissions as sales-linked, rent as fixed, utilities as semi-variable, and staffed roles as semi-fixed so contribution margin doesn’t look stronger than cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent Cafe Space	Fixed	Use $4,500 per month from Month 1 through Month 60.	Spreading rent by order and hiding the real monthly hurdle.
POS System & Software	Fixed	Use $150 per month as a stable operating charge.	Treating software like a transaction fee when it doesn’t move with sales.
Raw Ingredients Beverages	Variable	Apply 7.0% of first-year sales, falling to 6.0% by Year 5.	Leaving waste out of ingredient assumptions.
Raw Ingredients Food & Desserts	Variable	Apply 4.0% of first-year sales, falling to 3.2% by Year 5.	Using menu price only and missing spoilage or prep loss.
Delivery Platform Commissions	Variable	Apply 4.0% of first-year sales, falling to 3.0% by Year 5.	Blending delivery sales with walk-in sales and overstating margin.
Marketing & Local Promotions	Variable	Apply 3.0% of first-year sales, falling to 2.4% by Year 5.	Locking promotions as fixed and missing volume-linked campaign spend.
Utilities	Semi-variable	Start with the $800 monthly base, then flex usage with traffic.	Treating utilities as fully fixed when busy periods raise usage.
Cafe Manager, Head Barista, Barista Server, and Kitchen Staff payroll	Semi-fixed	Use $192,000 per year, about $16,000 per month, in Year 1; step up as FTEs increase.	Treating all labor as variable instead of staffing in capacity steps.

How does break-even change across lean, base, and full sandwich shop scenarios?

Scenario table

As sales grow, fixed costs take a smaller bite, so break-even risk drops. The base and full cases show a bigger cushion because contribution stays above 82% while revenue scales faster than overhead.

These are planning assumptions, not guaranteed demand or profit.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean sandwich shop	$569k	$102.4k	$223k	82%	$243.6k	Planned sales are about 2.1x break-even, so the cushion is thin but positive.
Base sandwich shop	$883k	$151.8k	$247k	82.8%	$484.1k	Planned sales are about 3.0x break-even, so the buffer is healthier.
Full sandwich shop	$1.34m	$216.8k	$281k	83.8%	$838.4k	Planned sales are about 4.0x break-even, so fixed costs are well covered.

What pushes a sandwich shop past break-even?

Stress test

The Year 1 plan has about $297k of monthly cushion before break-even, but slow weekday lunch, waste, overstaffing, higher delivery fees, and rent creep can shrink it fast. Sales and margin both matter.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; monthly sales stay at $569k, fixed costs stay at $223k, and variable expenses stay at 18%.	$272k	$297k cushion	Healthy cushion, but fixed costs are still heavy.
Revenue shortfall	Monthly sales fall 15% to about $484k.	$272k	$212k cushion	Slow weekday lunch traffic trims the safety margin.
Fixed-cost pressure	Fixed costs rise by $10k per month to $233k.	$284k	$285k cushion	Rent or payroll creep pushes breakeven higher.
Margin pressure	Variable expenses rise to 20%, cutting contribution margin to 80%.	$279k	$290k cushion	Higher delivery fees, waste, or promo spend eat margin.
Combined pressure	Sales fall to $272k, fixed costs rise to $233k, and variable expenses rise to 20%.	$291k	$19k gap	This is the launch danger zone; the model turns tight fast.

Can this sandwich shop clear break-even before you sign the lease and hire the team?

Founder checklist

Don’t commit until the shop can support about 70 break-even orders a day and the Year 1 plan of about 146 covers a day. If the site, staffing, or supplier terms miss that load, the model slips past Month 3 breakeven fast.

1Demand proof146/day

Check that the site can sell about 146 covers a day at a blended check near $12.6, because that is the Year 1 demand plan and it sits well above the 70-order break-even floor.

2Fixed load$22.3K/mo

Confirm the $4,500 rent still works after utilities, software, insurance, maintenance, cleaning, and phone, because fixed overhead is about $22.3K a month before payroll.

3Margin lock82% CM

Lock supplier pricing so Year 1 raw ingredients stay near 11% and delivery plus local promotion stay near 7%, which leaves about 82% contribution margin to pay rent and labor.

4Staffing ramp$192K payroll

Keep Year 1 staffing at the modeled 5.0 FTE and make sure the $192K payroll can cover Friday through Sunday peaks without pushing waste or overtime too high.

5Cash cushion$829K low

Do not open until you can fund the $85K startup capex and still carry the model's Month 2 cash low of about $829K.

6Launch paceMonth 3

Run a tight opening test on prep, waste, and reorder timing, because breakeven lands in Month 3 and weak launch demand will stretch payback.
