Which concrete reinforcing steel supply expenses are fixed, and which move with sales?

Cost classification

Break-even is reliable only when each expense is classified by how it behaves. If freight, commissions, or staffing steps are treated as fixed, Month 1 break-even can look safer than cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Distribution Center Lease	Fixed	Use the $18,500 monthly lease as a stable monthly burden across the planning range.	Treating warehouse rent as unit-driven and understating break-even volume.
Logistics Software Licensing	Fixed	Include the $2,400 monthly license in fixed overhead from Month 1 through Month 60.	Leaving software out because it does not touch inventory directly.
Facility Insurance	Fixed	Carry the $1,800 monthly premium as fixed overhead in the operating break-even model.	Spreading insurance by ton and hiding the monthly cash floor.
Raw Steel Inbound	Variable	Apply the $85 per unit charge to each Standard Grade Rebar unit sold or handled.	Modeling raw inbound steel as a flat warehouse expense.
3PL Logistics and Freight	Variable	Model freight at 6.5% of first year revenue, then adjust by year as the forecast rate changes.	Using one flat freight budget while sales volume rises.
Sales Commissions	Variable	Apply commissions at 3.0% of first year revenue, tied directly to sales volume.	Counting commissions as fixed payroll instead of deal-linked spend.
Industrial Utilities	Fixed	Use the model’s $3,200 monthly amount as fixed, even though shop usage may vary in operations.	Switching treatment mid-model without changing the break-even formula.
Warehouse Supervisor staffing	Semi-fixed	Hold one full-time role early, then step up when the model adds capacity in later years.	Smoothing headcount as a percentage of revenue instead of adding real hires.

How does break-even change from a lean start to full scale in concrete reinforcing steel supply?

Scenario table

The break-even point moves with revenue mix, freight, and staffing. Here, lean volume barely covers overhead, while the base and full cases clear fixed costs with more cushion.

Planning assumptions only; actual results will move with product mix, delivery density, and inventory turns.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean break-even case	$95K	$22K	$73K	77.1%	$0	Just covers overhead; any dip creates cash stress.
Year 1 base case	$3.83M	$878K	$73K	77.1%	$2.88M	Fixed costs clear in Month 1, so break-even risk is low.
Year 5 full capacity	$11.60M	$2.32M	$104K	80.0%	$9.18M	Wider cushion, but it still depends on steady backlog and fast inventory turns.

What pressures the break-even plan for this concrete reinforcing steel supply business?

Stress test

The plan clears the floor by a wide margin, but freight, commissions, and overhead are the first pressure points. Base break-even sits near $944K a month, so the real risk is how fast that floor climbs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$944K/month	$2.89M cushion	The plan has room, so break-even is not the first risk.
Revenue shortfall	Monthly sales run 20% below the Year 1 average.	$944K/month	$2.12M cushion	A softer start still clears break-even, but the cushion shrinks.
Fixed-cost pressure	Monthly overhead rises by $10K.	$957K/month	$2.88M cushion	Small overhead creep pushes the floor up fast.
Margin pressure	Freight and commissions rise 4 points of revenue.	$995K/month	$2.84M cushion	Delivery and selling costs can compress the spread before sales do.
Combined pressure	Monthly sales fall 20%, overhead adds $10K, and freight plus commissions widen 4 points.	$1.01M/month	$2.06M cushion	This is the real stress case: slower starts and weaker spread can drain cash fast.

What should you verify before signing the yard lease and buying the first steel?

Founder checklist

Before you lock the yard, make sure signed demand can clear the $94K monthly break-even line and that you can fund the $1.5M opening reserve. If either is soft, phase the lease, hires, and equipment.

1Demand floor$94K/mo

Verify signed work and repeat contractor demand can clear the monthly break-even line before you commit to space, inventory, or dispatch capacity.

2Fixed load$32.5K/mo

Lease, software, insurance, utilities, marketing, and maintenance total $32.5K a month, and Year 1 payroll adds $485K a year, so check that overhead won't outrun cash.

3Margin cushion84.6% to 86.1%

Check that direct variable costs still leave this gross margin range after freight and commissions, because a few points of slippage can flip the break-even date.

4Ramp plan$625K + 5.0 FTE

Use the five Year 1 roles and phase the $625K equipment list only as volume rises, so labor and machines don't outrun sales.

5Cash reserve$1.5M

Hold the Month 1 minimum cash reserve of $1.5M, because heavy equipment, stock, and payroll hit before receivables collect.

6Route testMonth 1

Test delivery routes in the opening month before promising contractor schedules, so transit times and freight stay inside the plan.
