Cost classification

Break-even works only when monthly overhead, per-session costs, and staffing steps are separated. Keep one-time vehicle, equipment, inventory, booking setup, wrap, power stations, and office equipment out unless financed or depreciated.

Expense	Cost	Break-Even Treatment	Common Mistake
Software Subscriptions	Fixed	Use $550 per month as recurring overhead from Month 1 through Month 60.	Treating booking software as if it rises with each visit.
Storage Unit Rental	Fixed	Use $700 per month until the storage footprint changes.	Spreading storage across sessions and reducing it when volume dips.
Whitening Gels & Kits	Variable	Model at 5.0% of revenue in the first year, stepping down to 4.5% by the fifth year.	Budgeting a flat dollar amount while kit usage rises with visits.
Consumable Supplies	Variable	Model at 2.0% of revenue in the first year, then 1.8% from the third year onward.	Leaving disposables in overhead instead of tying them to sessions.
Payment Processing Fees	Variable	Model at 2.5% of revenue in the first year, declining to 2.2% from the fourth year onward.	Ignoring card fees when higher-priced services lift the ticket.
Vehicle Fuel & Maintenance	Semi-variable	Use 4.0% of revenue in the first year because route miles change with appointment density.	Treating mileage as fixed when longer routes add real spend.
Mobile Whitening Technician Payroll	Semi-fixed	Add payroll in capacity steps: 0.5 FTE in the first year, 1.0 in the second year, and 2.0 in the third year.	Adding labor smoothly per visit instead of when capacity is hired.
Lead Mobile Technician Payroll	Semi-fixed	Use the $60,000 annual salary as a service-capacity block needed before visit volume scales.	Treating salaried coverage as variable with each booking.

How does break-even change from lean launch to full activity?

Scenario table

As visits rise, revenue grows faster than fixed payroll, so break-even gets easier even as staffing costs climb. Higher-tier service mix also lifts the contribution margin, which gives the full-activity case the biggest cushion.

Planning figures use model assumptions, so real results can move with route density, mix, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$28.5k	$3.8k	$16.4k	86.5%	$8.2k	Needs about 116 appointments a month; thin route fill is the main risk.
Base case	$45.0k	$5.8k	$22.5k	87.1%	$16.7k	About 149 appointments a month cover fixed costs, so the cushion is steadier.
Full activity case	$103.4k	$12.4k	$35.4k	88.0%	$55.6k	About 211 appointments a month cover fixed costs, and the higher-ticket mix gives the widest cushion.

What breaks this mobile teeth whitening break-even plan?

Stress test

The base Year 1 plan has a wide cushion, but slower bookings, higher overhead, or a weaker margin can erase it fast. The business stays safe until revenue slips near the $190k break-even line.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base Year 1 plan.	$190k	$138k cushion	Healthy cushion if bookings hold.
Revenue shortfall	Revenue falls 40% from the base plan.	$190k	$6k cushion	A sales dip nearly wipes out the cushion.
Fixed-cost increase	Fixed costs rise by $3k per month.	$231k	$97k cushion	Overhead cuts into room to absorb shocks.
Margin pressure	Variable expenses rise to 18.5% of revenue.	$201k	$127k cushion	Fuel and fee creep keep less cash per sale.
Combined pressure	Revenue slips, fixed costs hit $194k, and variable expenses rise to 18.5%.	$238k	$7k gap	Small misses turn the month negative.

What should you verify before you buy the vehicle and start hiring for mobile teeth whitening?

Founder checklist

Start with bookings and ticket mix. If you can’t hold about 100 monthly bookings at a roughly $189 average ticket, the about $164K fixed load and early staffing will outrun cash before Month 5 break-even shows.

1Booking Proof100/mo

Verify you can keep booking volume near 100 appointments a month, because that is the demand level the model needs before the launch spend makes sense.

2Ticket Mix$189 AOV

Verify the service mix and aftercare sales hold the Year 1 average ticket near $189, since weaker pricing pushes break-even out fast.

3Fixed Load$164K/yr

Verify your fixed overhead stays around $164K a year, because that is the cost base the bookings have to cover before the business is truly ready.

4Margin Stack86.5% CM

Verify gels, kits, fuel, and card fees stay near the modeled direct-cost stack, so each visit still leaves enough contribution margin to pay overhead.

5Visit Capacity8/day

Verify the owner and first technician can really serve about 8 visits a day, and track cancellations and drive time weekly before adding more staff.

6Cash Runway$828K

Verify the Month 2 cash trough of $828K is covered and do not accept paid bookings until intake, payments, coverage, and equipment are live, because early friction can push break-even past Month 5.
