Cost classification

Break-even gets cleaner when rent and base payroll sit in monthly overhead, while inventory, class materials, and card fees are deducted from each sale. If you bury sales-driven outflows in overhead, Month 18 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Lease	Fixed	Include $3,500 per month in overhead before measuring sales needed to break even.	Treating rent as tied to customer traffic.
Store Manager	Fixed	Include the $55,000 salary in payroll overhead across the planning range.	Spreading manager pay across units sold as if it disappears when sales dip.
Retail Associate	Semi-fixed	Model the $30,000 salary in staffing steps as coverage rises from 1.0 FTE to 2.0 FTE.	Assuming labor rises penny-for-penny with each order.
Workshop Instructor	Semi-fixed	Model the $40,000 salary by FTE, starting at 0.5 FTE in the first year and rising with class capacity.	Counting instructor pay as fully variable class material expense.
Utilities	Semi-variable	Include the $400 monthly baseline in overhead, with usage risk as store and workshop activity grows.	Ignoring higher utility use when classes and foot traffic increase.
Inventory Purchase Cost	Variable	Deduct 11.0% of first-year revenue before calculating contribution margin.	Putting inventory purchases in fixed overhead and overstating margin per sale.
Workshop Material Cost	Variable	Deduct 2.0% of first-year revenue because supplies move with class activity.	Forgetting class materials when testing workshop break-even.
Payment Processing Fees	Variable	Deduct 2.5% of first-year revenue as a sales-linked card processing outflow.	Leaving fees out because each charge looks small.

How does break-even shift between lean, base, and full store mixes for a cake decorating supply store?

Scenario table

Break-even moves with traffic and product mix. Higher weekend flow and a bigger class share lift revenue while variable costs stay near 18%, so the base case sits at cover and the full case adds cushion.

Planning assumptions, not guarantees; actual traffic, mix, and staffing can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean cake supply mix	$13,200	$2,376	$13,530	82%	-$2,706	Traffic is too light to cover fixed costs.
Base cake supply mix	$16,500	$2,970	$13,530	82%	$0	This is the break-even line, with no cushion yet.
Full cake supply mix	$19,800	$3,564	$13,530	82%	$2,706	Higher class mix gives the store a small profit buffer.

What pushes this cake decorating supply store off break-even?

Stress test

The base plan sits right at break-even at $16,500 a month, so there’s no cushion. A 10% traffic miss, 10% higher fixed costs, or vendor cost pressure quickly turns into loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$16,500	$0 cushion	No cushion; any miss turns into loss.
Revenue shortfall	Revenue falls 10% from the base plan.	$16,500	$1,353 gap	Weekday traffic softness creates an immediate loss.
Fixed-cost increase	Fixed costs rise 10% to $14,883 a month.	$18,150	$1,353 gap	Lease or payroll creep pushes break-even up fast.
Variable-expense pressure	Variable expenses rise from 18% to 23%.	$17,571	$825 gap	Slower inventory turns or shrink tighten cash.
Combined pressure	Revenue falls 20%, fixed costs rise 10%, and variable expenses rise to 23%.	$19,328	$4,719 gap	This is the danger zone; the miss compounds fast.

Can this cake decorating supply store clear break-even before you sign the lease and stock the first shelves?

Founder checklist

Test the store against the $16.5K monthly break-even before you lock the lease. If traffic, margin, and staffing do not support that number, the model still needs work; owner pay, taxes, and debt service stay out of basic break-even unless modeled separately.

1Traffic proof450/week

Verify the store can pull 450 weekly visitors and convert 20% of them, because that supports about 12 orders a day at a roughly $45.40 basket and the $16.5K monthly break-even.

2Margin mix82% CM

Check that the mix keeps Year 1 variable costs near 18% of sales, so contribution margin stays around 82% and the break-even math still works.

3Lease load$13.5K/mo

Keep rent at $3.5K and total fixed costs near $13.5K a month, or the $16.5K break-even revenue no longer covers the store's base burn.

4Launch kit$79K + $25K

Fund the $79K launch stack and the $25K opening inventory before opening, and lock lead times for tools, ingredients, and edibles so shelves are full on day one.

5Staff cover2.5 FTE

Confirm the manager, one associate, and 0.5 FTE instructor can cover Year 1 traffic and workshops, because the model adds more payroll in later years.

6Cash cushion$740K

Hold at least $740K of cash, since the model hits its low point in Month 21, posts -$81K EBITDA (earnings before interest, taxes, depreciation, and amortization) in Year 1, and takes 38 months to pay back.
