Which broom manufacturing expenses stay fixed, and which move with sales volume?

Cost classification

Break-even gets more reliable when rent, staffing steps, materials, and sales-linked fees are separated. Treating every factory expense as unit-based can hide cash needs before volume catches up.

Expense	Cost	Break-Even Treatment	Common Mistake
Factory Lease	Fixed	Use $5,000/month in overhead regardless of broom units sold within the current planning range.	Spreading rent per unit and assuming it falls when production dips.
Business Insurance	Fixed	Use $800/month as recurring overhead in the break-even base.	Leaving insurance out because it does not touch production directly.
Accounting & Legal Fees	Fixed	Use $1,200/month as administrative overhead that must be covered before profit.	Modeling it only as a launch expense instead of a monthly operating expense.
Wood Handles	Variable	Use $1.50 per unit for each applicable broom produced and sold.	Budgeting materials as a flat monthly amount instead of tying them to unit volume.
Synthetic Bristles	Variable	Use $1.80 per unit for each applicable broom produced and sold.	Using one blended material rate without checking product mix.
Direct Assembly Labor	Variable	Use the per-unit labor rate from $0.30 to $0.80, depending on the broom type.	Treating all labor as fixed payroll and overstating margin on each unit.
Factory Utilities	Semi-variable	Use $1,500/month for the fixed portion plus 0.5% of revenue for production usage.	Treating utilities as fully variable when the base bill remains due.
Assembly Technician Staffing	Semi-fixed	Model staffing in capacity steps, rising from 2.0 FTE in the first year to 5.0 FTE by Year 4.	Assuming labor scales smoothly with sales when hires come before full volume.

How does break-even shift from lean to full broom manufacturing?

Scenario table

Here’s the quick math: higher output spreads the same plant and payroll over more brooms, so the break-even gap widens. Cash still bottoms at $942k in Month 13, so growth needs enough working capital to bridge the launch period.

Planning figures only; mix, labor use, and material costs can move break-even up or down.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 mix	$72.5k	$13.9k	$50.4k	80.9%	$8.2k	About $8.2k of monthly cushion, so break-even risk stays high.
Base Year 3 mix	$143.3k	$25.9k	$65.8k	81.9%	$51.5k	About $51.5k of monthly cushion, so overhead starts to fit.
Full Year 5 mix	$241.8k	$41.6k	$74.6k	82.8%	$125.6k	About $125.6k of monthly cushion, so break-even risk is much lower.

What breaks the broom factory’s break-even plan?

Stress test

Year 1 has about a $102k monthly cushion, with revenue near $725k against about $623k break-even. A 15% sales drop, 10% higher fixed costs, or a 5-point margin hit can erase that buffer fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; revenue stays about $725k a month.	$623k	$102k cushion	The base plan clears break-even, but the buffer is not huge.
Revenue shortfall	Revenue drops 15% to about $616k a month.	$623k	$7k gap	A modest sales dip pushes the model under break-even.
Fixed-cost increase	Fixed overhead rises 10% from about $504k to $555k a month.	$686k	$39k cushion	Overhead creep can eat most of the profit buffer.
Margin pressure	Contribution margin falls 5 points to 75.9%.	$664k	$61k cushion	Materials inflation or price cuts reduce room to absorb fixed costs.
Combined pressure	Revenue drops 15%, fixed overhead rises 10%, and contribution margin falls to 75.9%.	$840k	$115k gap	This mix creates about an $87k monthly loss and turns excess capacity into a real problem.

Is your broom line ready to break even before you lock the lease and buy equipment?

Founder checklist

Use this as a go/no-go check. Don’t sign the lease, buy the line, or add payroll until demand, pricing, margin, and cash all line up with the Month 13 break-even plan.

1Order proof1,790/mo

Verify you can sell about 1,790 brooms a month before locking full overhead, because that is the break-even run rate.

2Input supply5 inputs

Lock quotes for handles, bristles, heads, packaging, and direct assembly labor before you commit to volume, or margin will slip fast.

3Fixed burn$50.4K/mo

Check that monthly fixed costs and Year 1 wages stay near $50.4K, since that is the overhead the business must cover first.

4Contribution81% CM

Test that the mix still leaves about 81% contribution margin (CM) after unit costs, commissions, and payment fees, or break-even moves out.

5Capacity ramp47K units

Verify Year 1 production of 25,000 units fits the line setup, and keep quality control ready before the Year 3 ramp to 47,000 units.

6Cash cushion$942K

Hold at least $942K of cash for the Month 13 trough, and treat the Month 13 break-even date as a launch gate, not a promise.
