Which expenses stay fixed and which move with sales in a polycarbonate sheet distributor?

Cost classification

Break-even is reliable only if each expense behaves the way the model says it does. Here, the key is separating fixed facility overhead from revenue-linked materials, freight, commissions, and step-based staffing.

Expense Cost Break-Even Treatment Common Mistake
Warehouse and Fabrication Facility Lease Fixed Include at $18,500 per month from Month 1 through Month 60. Tying rent to sales volume instead of treating it as committed overhead.
Raw Material Bulk Procurement Variable Model as 12.0% of first year revenue, stepping down to 10.0% by mature year. Treating bulk inventory buys as startup spend instead of sales-linked input usage.
Fabrication Consumables and Tooling Variable Apply 2.0% of first year revenue, declining to 1.2% as process efficiency improves. Ignoring blade wear, scrap, and cut waste when estimating contribution margin.
Logistics and Freight Fulfillment Variable Charge 4.5% of first year revenue, improving to 3.5% as shipment density rises. Burying delivery loss in gross margin instead of showing it below product input costs.
B2B Sales Commissions Variable Deduct 1.5% of revenue when calculating contribution margin. Excluding commissions from break-even and overstating profit per order.
Industrial Utilities and Power Semi-variable Start with the $2,800 monthly base, then watch usage as CNC activity rises. Assuming power stays flat when fabrication hours and machine load increase.
Technical Sales Consultants Semi-fixed Use salary steps: 2.0 FTE in the first year at $85,000 each, rising with quote volume. Hiring ahead of qualified demand and adding payroll before orders support it.
ERP and CRM Software Subscriptions Fixed Include $1,500 per month from Month 1 as part of operating overhead. Adding software after break-even instead of recognizing it at launch.

How does break-even change across lean, base, and full launch paths for polycarbonate sheet sales?

Scenario table

Lean lands on the break-even line at about $1.09M a month, base clears it with Year 1 volume, and full scale adds profit but also heavier warehouse and inventory needs.

Planning figures only; actual break-even will move with pricing, freight, and payroll mix.
Scenario Monthly Revenue Variable Costs Fixed Costs CM Ratio Operating Profit Break-Even Signal
Lean regional launch $1.09M $218k $874k 80% $0 Any miss on volume pushes it below break-even.
Base Year 1 plan $546k $109k $87k 80% $349k Break-even is hit in Month 1, so the base plan has a solid cushion.
Full Year 2 scale-up $1.00M $190k $105k 81% $706k Profit cushion grows, but warehouse, delivery, and inventory cash needs rise.

What breaks the break-even plan for polycarbonate sheet sales?

Stress test

The plan clears break-even in the base case, but slower quote conversion, freight surcharges, supplier price resets, and idle warehouse space can narrow the cushion fast. Even so, the model still stays above break-even in each single-stress case shown here.

Stress Case Changed Assumption Break-Even Revenue Revenue Gap Risk Signal
Current plan No change from the base plan. $1,092K $4,366K cushion Strong cushion at launch.
Revenue shortfall Monthly revenue drops 25% to about $4,094K. $1,092K $3,002K cushion Quote conversion slows, but costs stay covered.
Fixed-cost increase Monthly fixed costs rise 15% to about $1,004K. $1,255K $4,203K cushion Idle space and overhead creep lift the break-even line.
Margin pressure Variable expenses rise from 200% to 250%. $1,164K $4,294K cushion Freight and supplier resets cut contribution margin.
Combined pressure Revenue drops 25%, variable expenses rise to 250%, and fixed costs rise 15%. $1,339K $2,755K cushion Still profitable, but the safety margin shrinks fast.

Can this polycarbonate sheet distributor clear break-even before signing the lease and buying inventory?

Founder checklist

Only sign the lease and bulk-buy inventory if monthly quote flow can clear about $1.092M in revenue and the opening cash cushion stays at $839K. The launch works only when fixed costs, freight, and hiring are covered first.

1Demand Floor$1.092M/mo

Check that quote volume and repeat orders can clear the modeled break-even revenue before you commit, because Year 1 sales average far below that level.

2Fixed Load$87.3K/mo

Make sure lease, utilities, software, insurance, marketing, and planned payroll fit the early order book, since this fixed burn has to be covered every month.

3Margin Mix80.0% CM

Confirm pricing still leaves about 80.0% contribution after raw material, tooling, freight, and sales commissions, because small margin slips move break-even fast.

4Procurement Terms12.0% + 4.5%

Lock supplier pricing and freight quotes before bulk buys, and keep storage flow clean, because Year 1 raw materials run 12.0% of sales and logistics run 4.5%.

5Staffing Ramp2 sales / 3 CNC

Hold the opening team at 2 technical sales consultants and 3 CNC fabrication specialists until quote volume justifies more labor, or payroll will outrun demand.

6Cash Cushion$839K

Keep the $839K minimum cash in Month 1 and treat the $470K capex as separate from operating break-even, so launch spending does not choke the runway.
