Which cleaning supply store expenses stay fixed, and which move with sales?

Cost classification

Break-even gets reliable only when rent, base payroll, and software stay fixed while product costs and fees move with sales. Misclassifying inventory or step-up labor can make Month 31 break-even look closer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Lease	Fixed	Include $3,500 per month in overhead across the planning range.	Reducing rent when sales dip instead of keeping it constant.
Store Manager and Full-Time Sales Associate Payroll	Fixed	Include $90,000 per year, or $7,500 per month, before volume-driven costs.	Treating base store coverage as variable because traffic is low.
Wholesale Product Cost	Variable	Apply 12.0% of revenue in the first year, declining to 10.0% by Year 5.	Treating inventory purchases as profit loss instead of sales-linked spend tied to stock turn.
Inbound Shipping & Logistics	Variable	Apply 2.5% of revenue in the first year, declining to 2.0% by Year 5.	Burying freight in fixed overhead and missing margin pressure on bulky orders.
Payment Processing Fees	Variable	Apply 2.0% of revenue in the first year, declining to 1.5% by Year 5.	Forgetting that card-heavy sales carry a fee on each transaction.
Packaging & Consumables	Variable	Apply 1.0% of revenue in the first year, declining to 0.8% from Year 4 onward.	Leaving bags, labels, and small supplies out of unit economics.
Utilities	Semi-variable	Start with $400 per month, then allow increases if hours, equipment demos, or usage rise.	Locking utilities as fixed even when store activity expands.
Marketing & Local Ads	Semi-fixed	Start with $500 per month, then step up only when the traffic plan needs it.	Assuming each extra ad dollar creates same-month sales.

How does break-even shift from a lean cleaning supply store to a fuller setup?

Scenario table

The contribution margin ratio (sales left after variable costs) improves as the mix shifts to higher-priced items, so more revenue can cover more payroll. The lean launch is the most fragile because overhead leaves less room for a miss.

Planning assumptions only; actual traffic, mix, and payroll can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch store	$18.03k	$3.16k	$14.88k	82.5%	-$0.01k	At the edge of break-even; small traffic misses matter.
Base growth store	$20.46k	$3.25k	$17.22k	84.1%	-$0.01k	Higher basket size helps, but payroll still keeps it tight.
Fuller store	$20.10k	$2.87k	$17.22k	85.7%	+$0.01k	Best cushion; stronger mix offsets the bigger overhead.

What breaks the break-even plan for a cleaning supply store?

Stress test

The base plan is barely at break-even: about $180K in monthly revenue against $149K in fixed costs. A 10% sales dip, higher overhead, or margin pressure can flip the month into a loss fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$180K	$0 cushion	The plan is tight, so small misses matter.
Revenue shortfall	Monthly sales fall 10% to $162K.	$180K	$18K gap	Lower foot traffic turns a flat month into a loss.
Fixed-cost pressure	Fixed overhead rises 10% to $164K.	$198K	$18K gap	Rent, wages, or overhead creep pushes break-even higher.
Margin pressure	Variable spend rises from 17.5% to 20.5%.	$187K	$7K gap	Higher wholesale prices, card fees, or shrinkage squeeze cushion.
Combined pressure	Sales fall to $162K, variable spend rises to 20.5%, and fixed costs reach $164K.	$206K	$26K gap	This mix can create about a $35K monthly loss.

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

Founder checklist

Don’t sign the lease or place the first inventory order until the traffic, basket size, and fixed-cost load all clear the math. With Year 1 assumptions, this store needs about 117 visitors a day at a 15% conversion rate just to reach break-even.

1Traffic Proof117/day

Verify the site can average about 117 visitors a day, because the Year 1 weekday range of 30 to 60 visitors only works if footfall is much stronger than the base forecast.

2Rent Load$14.9K/mo

Lock total monthly fixed cost near this level before extras, since rent, payroll, and overhead set the floor the store must cover every month.

3Unit Margin82.5% CM

Check supplier quotes against 12% wholesale, 2.5% inbound freight, 2.0% processing, and 1.0% packaging, because Year 1 leaves about $28.30 per $34.30 order to cover fixed costs.

4Open Mix40/25/20/15

Build opening inventory around household cleaners, eco cleaners, bulk janitorial, and cleaning tools in that mix, and install POS plus shrinkage controls before opening so stock counts stay clean.

5Staff Ramp3.0 FTE

Staff only to the model’s Year 1 load if traffic supports it, because the plan already assumes a manager, one full-time associate, and two half-time roles.

6Cash Buffer$489K

Protect this reserve before launch, because minimum cash hits $489K in Month 36 and payback takes 56 months, so the store needs a long runway.
