Which audio mastering studio expenses are fixed, and which move with sales?

Cost classification

Break-even gets unreliable when rent, project-linked tools, and hiring steps sit in the same bucket. Keep fixed overhead separate from variable delivery costs so Month 8 break-even is tied to real operating behavior.

Expense	Cost	Break-Even Treatment	Common Mistake
Studio Lease & Rent, $3,500/month	Fixed	Include in monthly overhead before calculating required billable hours.	Tying rent to project count.
Utilities & Internet, $450/month	Semi-variable	Start as overhead, then watch usage from large uploads and file transfers.	Ignoring upload-heavy work.
Professional Insurance, $275/month	Fixed	Include before launch as recurring monthly overhead.	Treating required coverage as optional.
Accounting & Legal Services, $650/month	Fixed	Include monthly in the break-even base.	Pushing the expense to year-end only.
Equipment Maintenance & Calibration, $300/month	Semi-fixed	Build a monthly reserve for gear upkeep and scale it with studio load.	Waiting for gear failure.
Software Licensing & Plugin Subscriptions, 8% of first-year revenue	Variable	Tie to revenue in this model as project volume grows.	Double counting initial software licenses.
Marketing & Digital Advertising, 12% plus $24,000 first-year budget	Semi-variable	Separate the spend floor from the revenue-linked portion.	Assuming all marketing scales cleanly.
Senior Audio Engineer from Month 7, $65,000 salary at 0.5 FTE in first year	Semi-fixed	Model as a hiring step once booking demand supports capacity.	Adding staff before demand supports it.

How does break-even change from a lean opening mix to a full booking studio?

Scenario table

Break-even is tight in the lean opening mix, steadier in the base year, and much safer in the full booking year because revenue rises faster than variable costs, even as payroll and studio overhead grow.

Planning cases only, not guarantees; normalize later-year mix shares before project-count planning.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening mix	$25.3k	$7.8k	$15.3k	69%	$2.2k	Near break-even, with about $3.1k of monthly cushion.
Base growth mix	$61.2k	$17.0k	$23.5k	72.2%	$20.6k	Comfortable cushion; revenue stays well above break-even.
Full booking mix	$251.3k	$45.2k	$32.5k	82%	$173.6k	Wide cushion, but normalize the service mix before planning volume.

What breaks the break-even plan for this audio mastering studio?

Stress test

The launch cushion is thin. A 10% drop in revenue or a 10% rise in fixed costs turns a small monthly surplus into about a $1.6k gap, and 5 points of extra variable spend pushes break-even to roughly $27.0k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$25.1k	$0.2k cushion	Tiny cushion; a small booking miss can flip profit negative.
Revenue shortfall	Monthly revenue falls 10% to about $22.7k.	$25.1k	$1.6k gap	Fewer booked projects leave the studio below fixed-cost coverage.
Fixed-cost pressure	Fixed overhead rises 10% to about $19.0k.	$27.5k	$1.6k gap	A rent increase or extra payroll wipes out the current cushion.
Margin pressure	Variable expenses rise 5 points to 36%, cutting contribution margin to 64%.	$27.0k	$1.1k gap	More revisions or subcontracting can push margin below plan.
Combined pressure	Revenue falls 10%, fixed overhead rises 10%, and variable expenses rise to 36%.	$29.7k	$4.4k gap	Lower bookings, higher overhead, and weaker margin create a real cash burn risk.

Is the studio ready to sign the lease and buy gear?

Founder checklist

Only sign the lease and buy gear if booked work can carry the Year 1 run-rate and cash can survive the Month 2 dip. The model shows an $817K cash floor, so Month 8 break-even only works if demand, pricing, and repeat jobs land on time.

1Pipeline$25.3K/mo

Don't sign the lease until booked work can hold the Year 1 revenue run-rate, because paid demand has to beat the $120 CAC target before spend scales.

2Fixed load$5.48K/mo

Rent, utilities, insurance, accounting, web, gear upkeep, and supplies add up to $5,480 a month before payroll, so this load has to fit inside early bookings.

3Launch capex$109.7K

The listed studio build and launch gear totals $109.7K before working cash, so fund it only if the reserve plan still holds after Month 1.

4Unit margin69% CM

Software and cloud are 11% of revenue, and the full variable load is 31%, so set a written revision policy before contractor fees creep up.

5Volume ramp100 projects/mo

At the modeled service mix and prices, Year 1 revenue requires about 100 monthly projects, so confirm that load before hiring the Month 7 senior engineer.

6Cash floor$817K

Hold at least the modeled $817K cash floor because the low point lands in Month 2, and Month 8 break-even is not safe if onboarding or repeat work slows.
