Which distribution center expenses are fixed, variable, or step up as sales grow?

Cost classification

Break-even is only useful if each expense behaves the right way. In this model, fixed overhead starts at $22,300/month before payroll, while Year 1 revenue-linked costs take 26.5% of sales.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Lease & Rent	Fixed	Use $15,000/month from Month 1 through Month 60.	Flexing rent with order volume.
Utilities & Facility Maintenance	Fixed	Use $2,500/month unless a usage driver is added.	Changing it with sales without support.
Direct Warehouse Labor (Pick & Pack)	Variable	Model at 10.0% of Year 1 revenue, falling to 8.0% by Year 5.	Mixing hourly pick-and-pack labor with salaried supervisors.
Packaging Materials & Supplies	Variable	Model at 4.0% of Year 1 revenue, falling to 3.0% by Year 5.	Treating boxes, labels, and supplies as fixed overhead.
WMS Transaction & Hosting Fees	Variable	Model at 2.0% of Year 1 revenue, falling to 1.2% by Year 5.	Forgetting transaction fees rise with activity.
Client Support & Onboarding Costs	Variable	Model at 5.0% of Year 1 revenue, falling to 3.0% by Year 5.	Underbudgeting onboarding when new accounts ramp.
Sales Commissions & Referral Fees	Variable	Model at 4.0% of Year 1 revenue, falling to 2.0% by Year 5.	Counting gross sales before commission drag.
Operations Manager and Warehouse Supervisor Payroll	Semi-fixed	Add payroll in FTE steps as staffing rises by year.	Assuming managers scale smoothly with each order.

How does break-even shift from a lean launch to a full distribution center build?

Scenario table

Break-even gets easier as pricing moves from Year 1 to Year 5 and CM ratio rises from 73.5% to 81.8%. But payroll and marketing overhead also rise, so the base case is the best planning anchor.

Planning assumptions only; actual break-even will move with customer mix, service level, and hiring pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$105k	$28k	$76k	73.5%	$1k	About 53 active customer equivalents; small cushion, but one weak month matters.
Base Year 3 case	$150k	$34k	$117k	77.6%	$0k	About 58 active customer equivalents; this is the closest planning anchor.
Full mature case	$222k	$40k	$182k	81.8%	-$1k	About 71 active customer equivalents; scale lifts margin, but overhead grows too.

What breaks the break-even plan for a distribution center?

Stress test

Year 1 is tight because the model breaks even at about $1,032k a month and does not build cushion until Month 30. Overtime, slow onboarding, low storage attach rate, and unpassed shipping costs are the warning signs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,032k/month	$0 gap	Break-even lands in Month 30, so early cash stays negative.
Revenue shortfall	Monthly revenue is $10k below plan.	$1,042k/month	$10k gap	A small sales miss pushes the warehouse below break-even.
Fixed-cost pressure	Add $1k of monthly overhead.	$1,168k/month	$136k gap	Lease and support costs are the biggest fixed drag.
Margin pressure	Variable expenses rise by 1 percentage point.	$1,046k/month	$14k gap	Overtime or shipping fees not passed through raise break-even.
Combined pressure	Revenue misses $10k, variable costs rise 1 point, and overhead adds $1k.	$1,125k/month	$93k gap	The gap widens fast when sales, margin, and overhead all slip.

What should you verify before committing to the warehouse lease?

Founder checklist

Test the lease, staffing, and system plan against Year 1 break-even before you commit. For this distribution center, that means proving about $103K a month in revenue, matching the $415K capex plan, and keeping cash above the Month 30 trough.

1Demand proof$103K/mo

Confirm signed or near-signed volume can support this run rate, because weaker pipeline makes the lease and labor stack too heavy.

2Service mix$1,972/mo

Test whether the service mix really produces about $1,972 per active customer each month, since low-yield accounts miss break-even fast.

3Facility fit$415K capex

Verify dock access, ceiling height, racking fit, security, insurance, and safety before lease signing, or the build-out will stall.

4WMS readinessMonth 6

Make sure the warehouse management system is ready before high-volume onboarding, because the phase 1 build runs through Month 6.

5Staff ramp1.0→2.0 FTE

Hire against throughput, not hope, so labor scales with order flow instead of pushing fixed payroll above plan.

6Cash runway-$1.115M

Keep cash planning aligned with the Month 30 low point, because the model's minimum cash turns negative before payback arrives.
