Which expenses are fixed and which move with sales for an electronic component distributor?

Cost classification

Break-even is reliable only when warehouse overhead, sales-linked fees, and staffing steps are modeled separately. For this distributor, Month 1 break-even depends on keeping recurring fixed spend distinct from unit-driven purchasing and fulfillment.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Lease	Fixed	Model as $12,500 per month from Month 1 through Month 60, regardless of near-term order volume.	Scaling rent with revenue instead of treating it as committed space.
ERP and CRM Software Subscriptions	Fixed	Model as $3,200 per month across the planning period.	Linking subscriptions to sales volume without a priced user-tier change.
Digital Marketing and SEO Retainer	Fixed	Model as $6,500 per month unless management changes the retainer scope.	Using it as a percent of revenue and overstating break-even variability.
Warehouse Utilities and Insurance	Semi-variable	Start with the $2,800 monthly baseline, then test volume-driven utility pressure as throughput rises.	Treating every dollar as fixed when packing, lighting, and handling usage can rise.
Payroll	Semi-fixed	Model staffing in capacity steps: 6 FTE in the first year, rising to 17 FTE by Year 5.	Spreading payroll as a smooth sales percentage instead of hiring in steps.
Shipping and Logistics Fulfillment	Variable	Apply 5.0% of revenue in the first year, declining to 4.2% by Year 5.	Leaving fulfillment in overhead and hiding margin pressure from order growth.
E-commerce Transaction Fees	Variable	Apply 2.5% of revenue in each forecast year.	Forgetting payment fees when converting gross sales into contribution margin.
Inventory Acquisition Cost	Variable	Apply 10.0% of revenue in the first year, falling to 9.0% by Year 5.	Treating inventory purchases as overhead instead of sales-linked product spend.

How does break-even change from a lean launch to a full operating build in electronic component distribution?

Scenario table

The business stays above break-even in all three cases, but the cushion widens as mix and staffing scale. Variable costs ease from 19.5% to 16.9%, while fixed costs rise from $61.6k to $113.0k a month as FTE moves from 6 to 17.

Planning case only; it uses model assumptions, not a guarantee of demand or margin.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch proxy	$325k	$63.4k	$61.6k	80.5%	$200.0k	Revenue sits above the $76.5k break-even line, so the cushion is solid.
Base case proxy	$740.7k	$134.8k	$86.9k	81.8%	$519.0k	Revenue sits above the $106.2k break-even line, so risk stays low.
Full operating proxy	$1.785m	$301.9k	$113.0k	83.1%	$1.370m	Revenue sits far above the $136.0k break-even line, so the cushion is strongest.

What if sales miss or costs rise before this distribution model scales?

Stress test

Year 1 has a wide cushion at plan, but break-even moves fast if revenue slips, fixed overhead rises, or supplier and freight costs tighten the margin. The core math is 19.5% variable expense and 80.5% contribution margin on $3.9M of Year 1 revenue.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$918K	$2.98M cushion	Healthy cushion, but margin depends on supplier and freight discipline.
Revenue shortfall	Year 1 revenue falls 10%.	$918K	$2.59M cushion	A sales miss still clears break-even, but the buffer shrinks.
Fixed-cost pressure	Monthly fixed costs rise 10%.	$1.01M	$2.89M cushion	Payroll, rent, or software creep pushes the floor up fast.
Margin pressure	Variable expenses rise 5 points to 24.5%.	$979K	$2.92M cushion	Supplier price pressure and freight inflation hit break-even first.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise 5 points.	$1.08M	$2.43M cushion	Three small hits together still clear break-even, but they cut room for error.

Is this wholesale component launch ready for the fixed-cost base and warehouse build?

Founder checklist

Yes, but only if Year 1 demand can support about $325K a month and the 80.5% contribution holds. At a $61.6K monthly fixed load, implied break-even is about $76.5K a month, so don’t commit to the bigger warehouse until supplier terms, cash, and receivables controls are proven.

1Demand Proof$325K/mo

Confirm manufacturers and repair technicians can buy at that pace, because the plan only works if Year 1 sales reach about $325K per month.

2Contribution80.5%

Verify that inventory acquisition, testing, shipping, and transaction fees still leave enough margin to cover payroll, rent, and marketing.

3Fixed Load$61.6K/mo

Keep the monthly fixed base near this level, and don’t sign a larger warehouse lease until turns and customer concentration are visible.

4Supplier Terms100% Yr1

Check that supplier terms can support the full Year 1 inventory acquisition plan without forcing early cash drains.

5Cash Cushion$823K

Fund the Month 1 reserve first, then stage the $390K capex across racking, testing, platform, handling equipment, IT, and security.

6Credit GuardNo upsizing

Set credit limits before large wholesale accounts grow, hire to the six-role Year 1 plan, and avoid a bigger lease until inventory turns and customer concentration show up.
