Cost classification

Break-even is only reliable when rent and staffed coverage sit above the line as fixed or semi-fixed, while card fees, freight, marketing, and shrinkage reduce contribution margin. Don’t treat inventory buys as fixed overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent	Fixed	Use $5,000 per month as overhead that must be covered before profit.	Spreading rent across units and calling it variable.
Utilities	Semi-variable	Start with the $800 monthly base, then watch usage as traffic and departments grow.	Holding utilities flat when store hours or volume increase.
Store Manager	Semi-fixed	Include one $65,000 annual salary from Month 1 as required store coverage.	Modeling management payroll as a percent of sales.
Sales Associate	Semi-fixed	Step payroll by staffing plan: 2 FTE in the first year, rising to 6 FTE by Year 5.	Averaging hourly coverage into every order sold.
Payment Processing Fees	Variable	Deduct 2.5% of first-year sales from contribution margin.	Using product margin and missing card fees.
Marketing & Advertising	Variable	Apply 5.0% of first-year sales as a demand-linked selling expense.	Treating all advertising as fixed overhead.
Freight In	Variable	Apply 3.0% of first-year sales as a landed-cost add-on, separate from merchandise margin.	Burying freight in inventory and hiding margin leakage.
Inventory Shrinkage	Variable	Reduce contribution margin by 1.5% of first-year sales for loss, damage, and count errors.	Treating inventory buys as fixed overhead instead of matching them to sales.

How does break-even change from a lean neighborhood store to a full staffing build?

Scenario table

Lean staffing breaks even on the smallest revenue base, but it leaves the least room if traffic softens. Base and full builds need more sales to cover payroll, so parking, contractor demand, and inventory depth matter more as you scale.

Planning assumptions only; actual sales, shrink, and merchandise cost can move the floor.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 neighborhood store	$35.1k	$4.2k	$21.6k	88.0%	$9.3k	Above the $24.5k floor, but the cushion is thin.
Base Year 2 staffed store	$100.9k	$11.2k	$28.6k	88.9%	$61.1k	Above the $32.2k floor and better protected.
Full Year 5 expanded store	$921.2k	$74.6k	$43.2k	91.9%	$803.3k	Well above the $47.0k floor, with strong upside.

What pushes this hardware store past break-even?

Stress test

The base plan only clears break-even if the store holds about $24,489 in monthly revenue before merchandise COGS. A small sales miss, higher rent, or one more hire can push the model into a gap because freight, shrinkage, and payroll add up fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Year 1 fixed costs stay at $21,550 and add-ons hold at 120%.	$24,489	$0 cushion	The base case has no room for a sales miss.
Revenue shortfall	Monthly sales land 10% below plan.	$24,489	$2,449 gap	A small traffic miss can erase the margin cushion.
Fixed-cost pressure	Add one sales associate at $35,000 a year.	$27,803	$3,314 gap	Payroll added before volume proves out raises the bar.
Margin pressure	Listed variable add-ons rise from 120% to 150%.	$25,353	$864 gap	Freight, shrinkage, and markdowns chip away at contribution.
Combined pressure	Rent rises $1,000, one sales associate is added, and add-ons move to 150%.	$29,961	$5,472 gap	Stacked cost pressure pushes break-even well above the base plan.

What should you verify before you commit to this hardware store lease and opening spend?

Founder checklist

Before you sign the lease, check that the site can carry $5,000 rent, that Year 1 traffic can reach 4,723 monthly visitors, and that the buildout can survive the $756K cash trough by Month 6. If those three do not hold, break-even slips fast.

1Lease fit$5,000/mo

Verify the location can support rent plus parking and receiving access, because bad site flow turns fixed cost into a break-even drag.

2Traffic proof4,723/mo | 25%

Check that Year 1 weekday and weekend traffic can really reach 4,723 monthly visitors and convert at 25% before you overbuild labor.

3Fixed load$21.55K/mo

Make sure rent, utilities, insurance, accounting, software, security, cleaning, and Year 1 payroll can be covered before owner draw.

4Margin check88% CM

Confirm freight, shrinkage, payment processing, and marketing stay near plan, because the store only breaks even if contribution margin holds.

5Staff ramp4 FTE

Verify that 1 manager, 2 sales associates, and stock and receiving coverage can handle opening demand without pushing payroll higher too early.

6Cash cushion$756K by M6

Stress-test the cash plan against leasehold improvements, racks, POS, delivery van, forklift, security, and opening marketing, because the trough lands in Month 6.
