Which cassette digitizing expenses are fixed, and which move with sales?

Cost classification

Your break-even math is only as good as the labels. Keep stable monthly overhead fixed, let percentage fees move with sales, and treat payroll as a step when staffing capacity changes.

Expense	Cost	Break-Even Treatment	Common Mistake
Climate Controlled Studio Rent	Fixed	Include $3,200 per month in fixed overhead before calculating required monthly revenue.	Spreading rent across each tape and making it look variable.
Utilities and High Speed Fiber	Fixed	Add $450 per month to the monthly break-even base for the relevant planning range.	Reducing it during slow months even though the bill still arrives.
Professional Audio Software Subscriptions	Fixed	Include $250 per month as recurring operating overhead.	Leaving small subscriptions out of break-even because they feel minor.
Payment Processing Fees	Variable	Apply 3.5% of revenue as a sales-linked expense that lowers margin.	Modeling card fees as a flat monthly charge.
Secure Shipping Materials	Variable	Apply 8.0% of first-year revenue, then adjust by the model’s later-year percentages.	Treating mailers and packaging as fixed supplies.
Cloud Storage and File Delivery Fees	Variable	Apply 4.0% of first-year revenue because storage and delivery rise with completed work.	Hiding file delivery inside website hosting.
Physical Media Consumables	Variable	Apply 5.0% of first-year revenue, with later percentages declining as modeled.	Ignoring the physical delivery mix when estimating margin.
Lead Audio Technician Payroll	Semi-fixed	Hold payroll at 1.0 FTE through the first three years, then step to 1.5 FTE and 2.0 FTE as capacity grows.	Making technician pay move dollar-for-dollar with each order.

How does break-even change across lean, base, and full cassette-to-digital operating models?

Scenario table

Break-even is tight in Year 1 because fixed payroll and studio costs eat most of the margin. By Year 3, more restoration and delivery lift the margin, but staffing also climbs, so the cushion grows more slowly than revenue.

Planning assumptions only; actual break-even will move with order mix, staffing pace, and customer volume.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch break-even case	$26.9k	$5.5k	$21.4k	79.5%	$0	No cushion; one weak month turns profit negative.
Year 1 base case	$32.2k	$6.6k	$21.4k	79.5%	$4.2k	Small cushion; Month 6 break-even fits the model.
Year 3 full-scale case	$101.6k	$17.8k	$37.5k	82.5%	$46.3k	Much wider cushion, but higher staffing keeps fixed costs up.

What breaks the break-even plan for cassette-to-digital conversion?

Stress test

Year 1 has about a $70k cushion above a $252k break-even. That cushion narrows fast if add-ons fall, the specialist hire moves earlier, or variable costs push above the 20.5% Year 1 level.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$252,000	$70,000 cushion	Positive cushion, but a small miss can erase it.
Revenue shortfall	Year 1 revenue falls 10% from plan.	$252,000	$38,000 cushion	A modest sales miss cuts the buffer almost in half.
Fixed-cost increase	Add the Audio Restoration Specialist at full-time in Year 1.	$325,000	$3,000 gap	Pulling staffing forward nearly wipes out the cushion.
Margin pressure	Variable expenses rise 2 points as handling and remake work increase.	$259,000	$63,000 cushion	A small margin slip raises the break-even floor.
Combined pressure	Year 1 revenue falls 10%, add the specialist in Year 1, and variable expenses rise 2 points.	$333,000	$43,000 gap	The plan goes under water fast if all three move against you.

Can the tape-to-digital shop clear break-even before you lock the lease and hire?

Founder checklist

Before you lock the lease or hire, prove the order flow and cash can carry Month 6 break-even. If you can’t clear 235 weighted orders a month, the standard-only test rises to about 360 orders and the base is too heavy.

1Demand proof235 weighted/mo

Verify you can book at least 235 weighted orders (mix-adjusted orders) each month before the lease, or about 360 standard-only orders if you test a simpler offer mix.

2Unit margin79.5% pre-fixed

Keep shipping, cloud, processing, and consumables near plan, because 79.5% of revenue still has to cover about $18.8K a month in rent, software, insurance, admin, and payroll.

3Capacity ramp20/15/5 hrs

Confirm the month can handle 20 standard hours, 15 restoration hours, and 5 physical media hours so the order mix does not outrun staffing.

4Workflow control6-step flow

Test intake, labeling, chain of custody, tape inspection, backup storage, and file delivery end to end, because one weak handoff can turn low-margin work into rework.

5Launch capex$74.2K

Set aside the $74.2K of launch capex for equipment, studio setup, storage, furniture, and the site build before you judge monthly break-even.

6Cash runway$822K

Hold the $822K minimum cash through Month 2 and delay extra hiring if Month 6 break-even slips.
