A warehouse operations business in this model needs about $298,000 in monthly revenue to break even in Year 1 Here’s the quick math: $144,700 in fixed monthly overhead divided by a 485% contribution margin equals $298,351 Fixed overhead includes $67,200 in facility and admin costs plus $77,500 in salaried payroll The model still shows Year 1 EBITDA of -$1142 million and break-even in Month 20, so cash depth matters as much as margin

Which warehouse expenses stay fixed, and which move with sales volume?
Cost classification
Break-even is only reliable if fixed overhead stays separate from volume-driven work. In this model, the key split is base facility and payroll load versus labor, freight, packaging, and support that rise with customer activity.

Cost
Break-Even Treatment
Common Mistake
Warehouse lease
Fixed
Carry $45,000 per month in fixed overhead for the relevant planning range.
Allocating rent to each order and making break-even look too sensitive to volume.
Office rent
Fixed
Include $8,500 per month below contribution margin as fixed operating overhead.
Leaving office rent out because it does not touch the warehouse floor.
Insurance
Fixed
Include $3,200 per month as a stable operating charge before break-even volume.
Modeling insurance as a percentage of sales without data to support it.
Salaried payroll
Fixed
Use $77,500 per month for first-year salaried roles until headcount steps up.
Cutting base management payroll at low volume and overstating early margin.
Warehouse labor
Variable
Apply 18.0% of revenue in the first year as handling work tied to throughput.
Treating all warehouse labor as fixed when handling work moves with throughput.
Shipping and freight
Variable
Apply 8.0% of revenue in the first year because shipping rises with fulfillment activity.
Averaging freight into overhead and hiding unit-level margin pressure.
Utilities
Semi-variable
Start with the $4,800 monthly base, then watch usage pressure as volume grows.
Treating power, lighting, and warehouse usage as fully fixed forever.
Operations managers and warehouse supervisors
Semi-fixed
Add these in staffing steps as capacity and operating complexity increase.
Adding managers too early, then blaming break-even miss on pricing.
How does break-even shift from a lean warehouse setup to base and full operating formats?
Scenario table
Lean keeps fixed cost lighter, so break-even comes sooner even with a thinner margin. Base and full formats add payroll and support, which raises the revenue needed to cover the larger cost base.
Planning assumptions only; actual break-even will move with occupancy, service mix, and handling density.

What breaks the Year 1 break-even plan?
Stress test
Year 1 break-even sits at $298,351 of monthly revenue against $144,700 of fixed overhead, with a 48.5% contribution margin, the cash left after variable costs. Low occupancy, overtime-heavy shifts, freight pass-through delays, utility pressure, and a slow customer ramp can push this model under fast.

Can this warehouse carry its lease and buildout before you sign?
Founder checklist
Before you sign the lease or buy equipment, test whether the model can carry $144.7K in monthly fixed cost and still reach break-even by Month 20. If launch revenue cannot get near $298.4K a month, the plan will keep burning cash through Month 19.
1Lease Load$45.0K/mo
Confirm the warehouse lease stays inside the monthly rent line, because that cost starts before volume does.
2Fixed Base$144.7K/mo
Add rent, payroll, and overhead to prove the business can carry the full monthly fixed base without stretched hiring or delayed bills.
3Revenue Run-Rate$298.4K/mo
Test whether the launch plan can get to about $298,351 in monthly revenue, since break-even sits behind that run rate.
4Service Mix$299 / $799 / $1,499 / $2,999
Check that early deals track the Year 1 price ladder so the mix does not slide into low-value storage work.
5Cost Stack51.5%
Keep warehouse labor, freight, packaging, acquisition, technology, and support inside the 51.5% load, and only add people when throughput is there.
6Buildout Cash$1.19M / Month 19
Stage the $1.19 million setup spend and protect cash, because the trough reaches -$1.73 million in Month 19.
