Which used server resale expenses stay fixed, and which move with sales volume?

Cost classification

Break-even only works if fixed expenses and sales-linked expenses are separated cleanly. Treat freight, warranty claims, and parts as variable, or the model will understate the revenue needed to stay profitable.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease and Utilities	Fixed	Use $12,500 per month in fixed overhead for the relevant planning range.	Allocating rent to each server and hiding the true monthly break-even load.
Testing Software Subscriptions	Fixed	Include $1,200 per month before calculating contribution margin.	Treating required testing tools as optional when every unit must be verified.
Insurance and Liability	Fixed	Carry $2,500 per month as fixed operating overhead.	Leaving insurance below the line and overstating operating profit.
E-commerce Platform Fees	Fixed	Include the $850 monthly platform charge in fixed overhead.	Mixing the subscription with per-sale merchant fees in one line.
Hardware Acquisition and Parts	Variable	Model as 12.0% of revenue in the first year, falling to 10.0% by the fifth year.	Treating inventory purchases as fixed overhead instead of sales-linked gross margin pressure.
Shipping and Logistics	Variable	Apply 4.0% of revenue in the first year, improving to 3.2% by the fifth year.	Calling freight fixed even though bulky orders change the fulfillment bill.
Warranty Reserve Fund	Variable	Reserve 1.5% of revenue in the first year, easing to 1.1% by the fifth year.	Ignoring returns and warranty work until cash leaves the bank.
Senior Hardware Technician Payroll	Semi-fixed	Use $150,000 per year in the first year, then step up as technician headcount rises.	Modeling technician labor as fully variable by order instead of capacity added in hiring steps.

How does break-even change from a lean launch to a warehouse-backed base case and a fuller repair operation?

Scenario table

Break-even shifts because fixed costs stay heavy while revenue mix and margin density change. The lean case barely covers overhead, the base case leaves a solid cushion, and the full case pushes well past break-even.

Planning case figures are model assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean online-heavy launch	$832K	$166K	$666K	80%	$0	Just reaches break-even, so cushion is thin.
Base warehouse-backed reseller	$1,963K	$393K	$666K	80%	$904K	Clear profit cushion, but fixed costs still bite.
Full fulfillment and repair operation	$4,288K	$815K	$847K	81%	$2,626K	Far above the $1,045K break-even point.

What can break the break-even plan for used server equipment sales?

Stress test

Year 1 has a wide cushion, but freight, warranty, and marketplace fees can eat into it fast. A 25% revenue drop, a 15% overhead bump, or a move from 20% to 25% variable cost all pushes break-even higher.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$833K	$1,523K cushion	Strong Year 1 cushion.
Revenue shortfall	Revenue falls 25% to $1,767K.	$833K	$935K cushion	Demand softens, but break-even is still covered.
Fixed-cost pressure	Fixed costs rise 15% to about $766K.	$958K	$1,398K cushion	Overhead inflation trims headroom.
Margin pressure	Variable expense rate rises from 20% to 25%.	$887K	$1,469K cushion	Freight, fees, and warranty claims hit margin.
Combined pressure	Revenue falls 25%, fixed costs rise 15%, and variable expense rate moves to 25%.	$1,022K	$745K cushion	The cushion is still positive, but much thinner.

Is the used server reseller ready to commit to warehouse space, technicians, and bulk inventory?

Founder checklist

Don’t commit to bigger space or more headcount until channels, freight, and refurb steps are proven. The model hits break-even in Month 1, but cash still bottoms at $797K in Month 2, so the real test is whether operations can run without a cash squeeze.

1Channel Access$450 CAC

Confirm the sales channels can carry the Year 1 $120,000 ad budget at about $450 CAC before you buy bulk lots, because demand has to show up before inventory does.

2Fixed Burn$21.6K/mo

Confirm the fixed burn is really $21.6K a month from lease, software, insurance, platform fees, admin, and professional services, because break-even only works if overhead stays at model levels.

3Inventory TestTested lots

Verify repeat supplier access and test every unit before listing it, so bad lots and uninspected inventory do not erode the 80.0% Year 1 contribution margin.

4Freight Pricing4.0% ship

Price freight for rack servers and storage arrays before quoting customers, because shipping and logistics still run 4.0% of sales in Year 1.

5Launch Controls$30K capex

Set the refurb, data-sanitization, and return steps before launch, then hold packaging automation until sell-through justifies the $30,000 spend planned for Months 4 to 8.

6Cash Cushion$797K low

Keep enough cash for the $797K low in Month 2 and skip extra warehouse spend if sell-through slows, because the model’s payback still depends on a tight cash path.
