Which robot repair expenses are fixed, and which move with sales?

Cost classification

Break-even math only works when overhead stays separate from usage-driven repair work. Treat rent and salaried roles as base load, then apply labor, parts, licensing, and commissions as revenue-linked costs.

Expense	Cost	Break-Even Treatment	Common Mistake
Office & Dispatch Center Rent	Fixed	Include $7,500 per month in baseline overhead from Month 1 through Month 60.	Tying rent to service calls.
Utilities & Internet	Semi-variable	Start with the $1,200 monthly base, then review usage as workshop activity rises.	Ignoring higher workshop usage.
Vehicle Fleet Lease & Base Maintenance	Semi-fixed	Include $4,000 per month until route density or technician count forces the next vehicle step-up.	Missing the next van step-up.
Business Insurance & Licenses	Fixed	Include $2,500 per month as recurring overhead for the relevant planning range.	Treating it as a per-job charge.
Salaried Management Payroll	Fixed	Use first-year salaried roles as fixed overhead: $505,000 per year, or about $42,083 per month.	Burying payroll inside owner draw.
Field Technician Labor	Variable	Apply 12.0% of first-year revenue, falling to 9.0% by the fifth year.	Classifying all labor as fixed.
Spare Parts & Consumables	Variable	Apply 6.0% of first-year revenue, falling to 5.0% by the fifth year.	Counting inventory purchases as margin.
Sales Commissions & Performance Bonuses	Variable	Apply 3.0% of first-year revenue, falling to 2.0% by the fifth year.	Leaving commissions out of contribution margin.

How does break-even shift from lean launch to base and full scale for robot repair and maintenance?

Scenario table

Break-even gets safer as recurring contracts and technician use rise. Year 1 still runs below stable break-even, Year 2 reaches a modest cushion, and Year 3 has enough spread to absorb travel, parts, and labor swings.

Planning cases only; actual break-even will move with contract mix, utilization, and overhead.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$71k	$21.0k	$73.8k	70.5%	-$23.8k	Still below stable break-even; fixed overhead outruns margin.
Base routed service case	$183k	$49.6k	$98.8k	72.9%	$34.5k	Modest cushion; recurring contracts start carrying overhead.
Full scaled maintenance case	$342.5k	$83.9k	$129.3k	75.5%	$129.3k	Clear cushion; higher utilization supports a stronger break-even gap.

What breaks the break-even plan for a robot repair business?

Stress test

The plan breaks fastest if service calls soften, overhead rises, or parts and travel squeeze margin. A 10% revenue drop, a 10% fixed-cost hike, or 65.5% margin all push break-even above the $1,047,000 base case.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,047,000	$0 cushion	It clears fixed costs, but there is no buffer.
Revenue shortfall	Revenue falls 10% to about $943,000.	$1,047,000	$74,000 gap	Fewer service calls cut the cushion fast.
Fixed-cost pressure	Fixed overhead rises 10% to about $812,000.	$1,152,000	$105,000 gap	Rent, dispatch, and support costs widen the hole.
Margin pressure	Contribution margin falls to 65.5% from higher parts, travel, overtime, or discounting.	$1,127,000	$80,000 gap	Parts markup leakage and discounting lift the break-even bar.
Combined pressure	Revenue falls 10%, fixed overhead rises 10%, and contribution margin slips to 65.5%.	$1,241,000	$194,000 gap	Low demand and weak margin can turn into a fast cash drain.

What should you verify before buying the fleet, tools, and inventory for robot repair?

Founder checklist

Don’t sign the fleet lease or buy tools yet. First prove recurring repair demand, a realistic CAC, and enough cash to get past Month 15, because break-even starts in Month 10 but the cash trough lands near negative $485K.

1Demand Mix105% mix

Make sure recurring subscriptions, emergency repairs, and real bookings are not double-counted, because Year 1 allocations add to 105% and emergency work should stay an add-on, not the base case.

2Fixed Load$61.3K/mo

Confirm recurring revenue can carry the Year 1 fixed load of rent, utilities, insurance, professional services, IT, fleet base costs, and four salaried leaders before you sign the lease.

3Contribution70.5% CM

Price each plan so Year 1 field labor, parts, software, commissions, travel, and ads leave about 70.5% contribution margin before overhead.

4Route Capacity8.0 hrs

Check that each active customer really uses about 8.0 technician hours per month and that routes stay tight, or travel will push up faster than the 2.5% Year 1 load.

5CAC Test$2,500

Test whether the $2,500 customer acquisition cost fits the sales cycle, because a long close can make marketing spend arrive before service revenue.

6RunwayMonth 15

Keep cash alive past Month 15, since the model bottoms near negative $485K even though break-even starts in Month 10.
