Which expenses stay fixed, and which move with sales in a holographic illusion installation business?

Cost classification

Break-even only works if fixed overhead and sales-linked spend are kept separate. Here, the fixed monthly base is $21,000 before payroll, while commissions, freight, marketing, and unit build costs move with revenue or unit volume.

Expense	Cost	Break-Even Treatment	Common Mistake
R and D Facility Rent	Fixed	Include $12,000/month in the $21,000 fixed overhead base.	Treating rent as project labor.
Showroom Utilities and Maintenance	Fixed	Include $2,500/month even when no installation closes.	Burying showroom costs inside fabrication quotes.
Software Licensing and CMS Hosting	Fixed	Include $1,800/month as recurring platform spend.	Skipping the recurring hosting and licensing run-rate.
Insurance and Legal Fees	Fixed	Include $3,200/month in operating break-even.	Tying the expense only to signed projects.
Sales Commissions	Variable	Apply 5.0% of first-year revenue, then use the forecast rate by year.	Treating commissions as fixed payroll.
Shipping and Logistics	Variable	Apply 3.0% of first-year revenue for freight and site delivery.	Forgetting delivery cost on large installs.
Digital Marketing Spend	Variable	Apply 4.0% of first-year revenue before calculating contribution margin.	Counting marketing twice in overhead and variable spend.
Project Components and Install Labor	Variable	Use unit costs by display type, from $1,750 to $28,000 per unit.	Using one blended build cost for all display types.

How does break-even change across lean, base, and full-service installation mixes?

Scenario table

Break-even gets easier as the mix shifts from lean to full-service because revenue rises faster than variable spend and fixed payroll. The model clears break-even in all three cases, but only if bookings stay close to forecast.

Planning assumptions only; actual bookings, build time, and job mix can move these results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean retail showcase mix	$508,750	$177,250	$68,083	65.1%	$263,417	Clears break-even, but the cushion is still modest.
Base museum and lobby mix	$1,000,750	$338,334	$103,083	66.2%	$559,333	Break-even is covered with room, if the premium mix holds.
Full-service stage and studio mix	$1,582,083	$527,250	$138,083	66.7%	$916,750	Widest cushion, with the most room for slower months.

Can you prove enough booked work before you sign the lease and hire the crew?

Founder checklist

Don’t lock in fixed costs until booked work covers the opening load. The model points to about $103.1K in monthly booked revenue, $1.153M of minimum cash in Month 1, and a Month 2 break-even.

1Booked revenue$103.1K/mo

Verify signed pipeline, not warm leads, reaches this level before you add fixed commitments.

2Cash reserve$1.153M

Check that opening cash covers Month 1 needs without forcing a rushed sale or underpriced install.

3Margin mix66.6% CM

Confirm quotes, commissions, shipping, and marketing still leave enough contribution after direct build costs.

4Launch capex$445K

Secure vendor quotes for projectors, optics, frames, controllers, rigging, film, and test gear before you buy.

5Facility rent$12K/mo

Validate the site can earn its keep, because rent starts before the showroom and lab are fully productive.

6Payroll load$565K/yr

Hire only when booked work can support Year 1 payroll for technology, build, sales, and creative roles.
