Which expenses are fixed and which move with sales for this small retail store?

Cost classification

Break-even is more reliable when fixed overhead is separated from sales-linked expenses. For this store, that matters because the model reaches break-even in Month 5, so small classification errors can distort the target.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Lease	Fixed	Treat the $3,500 monthly lease as overhead that must be covered before profit.	Spreading rent per item and making it look lower when traffic dips.
Utilities	Semi-variable	Start with the $800 monthly plan, but expect usage to rise with refrigeration, hours, and traffic.	Treating all utilities as fully fixed at every sales level.
Wholesale Inventory Cost	Variable	Apply 15.0% of sales in the first year, declining to 14.0% by the fifth year.	Modeling inventory as a flat monthly bill instead of sales-linked spend.
Payment Processing Fees	Variable	Apply 2.0% of sales in the first year, falling to 1.8% by the fourth year.	Ignoring card fees when order volume rises.
Packaging and Supplies	Variable	Apply 1.5% of sales in the first year, falling to 1.2% by the fourth year.	Holding bags, cups, and supplies flat as orders grow.
Store Payroll	Semi-fixed	Model first-year staffing at about $11.1k per month, then step it up as full-time equivalent headcount rises.	Treating all labor as fully fixed or fully variable.
Local Marketing Initiatives	Semi-fixed	Use the $400 monthly base, then step it up only when campaign scope expands.	Linking every marketing dollar directly to sales.
Accounting and Legal Fees	Fixed	Treat the $250 monthly fee as recurring overhead in the operating break-even test.	Dropping it after launch as if it were a one-time setup item.

How does break-even change from a lean opening to base and full mini-mart traffic?

Scenario table

Lean opens close to break-even because Year 1 traffic and an 81.5% contribution margin only barely cover about $16.8k of monthly fixed costs. Base and full cases add cushion as traffic and basket size rise, but repeat buying still has to outrun store overhead.

Planning assumptions only; actual results can move with traffic mix, basket size, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening case, Year 1	$19.1k	$3.5k	$16.8k	81.5%	-$1.2k	Near break-even; a small traffic dip turns it negative.
Base case, Year 3	$32.4k	$5.7k	$24.1k	82.3%	$2.6k	Above break-even with a modest monthly cushion.
Full case, Year 5	$78.0k	$13.3k	$26.6k	83.0%	$38.1k	Comfortably above break-even, but fixed payroll still matters.

What breaks the mini-mart break-even plan first?

Stress test

The base plan only works if monthly sales hold near $20.6K. A 10% sales miss, a 10% jump in fixed costs, or 3 points of margin loss each push the break-even line higher and trim the cushion.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$20.6K	$0 cushion	No slack if sales dip.
Revenue shortfall	Opening sales land 10% below plan.	$20.6K	$2.1K gap	A 10% miss leaves little room for slow weeks.
Fixed-cost pressure	Fixed costs rise 10%.	$22.7K	$2.1K gap	Higher lease, utilities, or wages lift the hurdle fast.
Margin pressure	Variable expenses rise from 18.5% to 21.5% of sales.	$21.4K	$0.8K gap	Shrink, markdowns, and card fees cut the sales margin.
Combined pressure	Fixed costs rise 10% and variable expenses rise to 21.5%.	$23.6K	$3.0K gap	Cost inflation plus margin loss makes break-even much harder to hit.

Will this mini-mart clear break-even before you commit to the lease and opening build-out?

Founder checklist

Before you sign the lease and buy the first round of stock, make sure traffic, basket size, and cash all support break-even. Here’s the quick math: Year 1 averages about 181 visitors a day, and the model only works if 45% convert and each order stays near $7.75.

1Traffic Proof181/day avg

Verify weekday and weekend traffic really lands in the 140 to 250 visitor range and converts at about 45%, because that is what feeds break-even.

2Basket Value$7.75 basket

Verify a 2-unit order averages about $7.75 at the current mix, because smaller baskets push the breakeven day count higher fast.

3Fixed Load$16.8K/mo

Verify lease, utilities, POS, security, insurance, cleaning, marketing, and accounting stay near $16.8K a month, because that is the fixed load the store has to cover.

4Gross Margin81.5% CM

Verify wholesale inventory at 15.0%, payment fees at 2.0%, and supplies at 1.5% so contribution margin stays near 81.5%, or sales need to rise.

5Cold Capacity32% mix

Verify refrigeration and shelf space can support fresh food rising from 20% to 32% of mix, because the cold chain has to keep up with that shift.

6Cash Floor$846K floor

Verify the $123K opening capex fits inside your launch budget and you still keep the modeled $846K minimum cash in Month 2, because the store does not hit break-even until Month 5.
