Which store expenses are fixed, and which move with sales?

Cost classification

Break-even gets unreliable when fixed rent, volume-based product costs, and step-up staffing are blended together. Here’s the quick math logic: fixed costs are divided by contribution margin, while variable costs reduce that margin first.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Lease	Fixed	Use $18,000 per month in the fixed overhead pool, then divide by contribution margin.	Tying rent to sales when it stays due even on slow weeks.
Cost of Goods Sold	Variable	Deduct 58.0% of sales in the first year before calculating contribution margin.	Ignoring product margin pressure from shrink, spoilage, and markdowns.
Packaging and Delivery	Variable	Deduct 3.5% of sales in the first year because it moves with order volume.	Treating delivery handling as fixed overhead instead of order-linked spend.
Utilities	Semi-variable	Start with the $4,500 monthly base load, then track added usage from refrigeration, lighting, and traffic.	Modeling utilities as flat when higher volume can raise power use.
Cashiers	Semi-fixed	Model salary in staffing steps as cashier coverage rises from 4.0 FTE in the first year to 8.0 FTE in Year 5.	Treating all cashier labor as fully variable by transaction.
Stock and Shelf Staff	Semi-fixed	Increase payroll in blocks as shelf volume grows from 3.0 FTE in the first year to 7.0 FTE in Year 5.	Missing the labor step-up needed before sales fully catch up.
Insurance	Fixed	Include $2,800 per month in fixed overhead during the relevant planning range.	Dropping recurring coverage from break-even because it is not tied to orders.

How does break-even change across lean, base, and full supermarket formats?

Scenario table

Here’s the quick math: higher conversion and a better sales mix lift the CM ratio from 38.5% to 41.5%, but fixed costs also rise, so break-even revenue moves from about $200k to about $261k a month. The big signal is EBITDA moving from -$408k in Year 3 to $861k in Year 4.

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

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening	$200k	$122.9k	$77.1k	38.5%	$0	Thin cushion; a small traffic miss pushes it below break-even.
Base growth	$230k	$138k	$92k	40.0%	$0	At target, so margin and labor discipline decide whether it clears overhead.
Full-volume build	$261k	$152.6k	$108.4k	41.5%	$0	Strongest setup; Year 4 EBITDA turning positive points to the first real cushion.

What breaks the supermarket break-even plan?

Stress test

Year 1 break-even is about $200k a month, and the plan starts about $170k short. A 1-point margin slip or a $1,000 fixed-cost bump raises the bar fast, so traffic, labor, and shrink control matter.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$200,347	$169,659 gap	Base sales are still far below cover.
Revenue shortfall	Conversion visitor to buyer falls from 8.5% to 7.5%.	$200,347	$173,279 gap	Weak conversion widens the gap fast.
Fixed-cost increase	Store lease rises by $1,000 per month.	$202,944	$172,256 gap	Each extra $1,000 adds about $2,597 of break-even sales.
Margin pressure	COGS rises 1 point to 59.0% of sales.	$205,689	$175,001 gap	A 1-point margin slip lifts break-even to about $205,689.
Combined pressure	Conversion falls to 7.5%, lease rises $1,000, and COGS rises 1 point.	$208,356	$181,288 gap	Weak traffic and margin squeeze stack up fast.

Before you sign the lease, can you prove this supermarket can cover the lease, staff, and buildout?

Founder checklist

Start with traffic, margin, and cash. If Year 1 visitors miss 270 to 420 a day, conversion stays below 8.5%, or the Month 38 cash low is too deep, the lease and staffing plan are too early.

1Traffic Floor270-420/day

Verify the store can pull 270 to 420 visitors a day in Year 1, since that footfall is the base for every sales assumption.

2Launch Conversion8.5%

Test opening-week conversion at 8.5% before you hire to plan, because weaker buyer rates cut orders fast.

3Gross Margin38.5% CM

Hold COGS near 58% and packaging and delivery near 3.5%, which leaves about 38.5% contribution before fixed costs.

4Lease Load$18K/mo

Make sure the $18K lease fits inside the $32.8K fixed base before payroll, because rent and overhead are due even on slow weeks.

5Payroll Ramp$532K Y1

Staff by department, not hope, because Year 1 payroll totals $532K across management, cashiers, stock, produce, bakery, and procurement.

6Cash Buffer-$1.867M

Keep reserve cash for the Month 38 minimum cash point and the $410K buildout, including POS, inventory software, and $85K refrigeration and display cases, because breakeven only arrives in Month 39.
