Which vehicle repair shop expenses are fixed, variable, semi-variable, or semi-fixed?

Cost classification

Break-even is only useful if fixed overhead and sales-linked costs are separated. In this model, Month 9 break-even depends on treating lease and base payroll differently from parts, supplies, commissions, and platform fees.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease	Fixed	Model at $4,500 per month from Month 1 through Month 60.	Spreading rent across jobs and making break-even look too low.
Business Insurance	Fixed	Model at $400 per month as stable monthly overhead.	Leaving insurance out because it does not change with bay volume.
Parts and Fluids	Variable	Model as 19.0% of revenue in the first year, declining to 17.0% by Year 5.	Ignoring parts margin compression when repair mix gets heavier.
Shop Supplies	Variable	Model as 2.5% of revenue in the first year, declining to 2.0% by Year 5.	Treating supplies as petty cash instead of job-linked spend.
Technician Commissions/Bonuses	Variable	Model as 4.5% of revenue in the first year, declining to 3.5% by Year 5.	Treating all payroll as Variable instead of separating bonuses from salaries.
Digital Inspection Platform Fees	Variable	Model as 1.5% of revenue in the first year, declining to 1.0% by Year 5.	Booking inspection fees as software overhead when they rise with sales.
Utilities	Semi-variable	Start with the $800 monthly base, then watch usage as bays and equipment run longer.	Freezing utilities at the base amount after repair volume scales.
Lead Automotive Service Excellence (ASE) Technician	Semi-fixed	Model the $75,000 salary in steps; headcount rises from 1.0 to 2.0 full-time equivalents in Year 3.	Treating salaried technician capacity as a per-job variable charge.

How does break-even change from a lean launch to a base shop and then a full-capacity vehicle repair shop?

Scenario table

Lean stays under break-even, base clears it, and full capacity creates a wide cushion. The key swing is that fixed overhead rises, but revenue and contribution margin rise faster.

Planning assumptions only; actual break-even moves with labor hours, parts mix, and bay utilization.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch repair shop	$25.4k	$7.0k	$22.8k	72.5%	-$4.3k	Still below break-even; it needs about $31.4k a month to cover overhead.
Base repair shop with junior technician	$71.9k	$19.0k	$28.2k	73.5%	$24.7k	Above break-even with room to absorb the added hire and marketing.
Full-capacity vehicle repair shop	$303.6k	$71.3k	$41.9k	76.5%	$190.3k	Well past break-even; bay use is strong enough to carry the larger team.

What breaks the break-even plan for this vehicle repair shop?

Stress test

At about $376,000 in monthly revenue and $273,000 of fixed overhead, the plan sits right on break-even. Small sales dips, rent or wage hikes, and even a 1-point margin slip can turn that thin cushion into a loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$376,000	$0 cushion	The plan is essentially at break-even.
Revenue shortfall	Monthly revenue is $10,000 below plan.	$376,000	$10,000 gap	Weak repair demand quickly removes the cushion.
Fixed-cost pressure	Fixed overhead rises by $1,000 per month.	$377,400	$1,400 gap	Rent or wage creep pushes the shop below break-even.
Margin pressure	Variable expenses rise by 1 percentage point of revenue.	$381,800	$5,800 gap	Parts discounts or bonus pressure raise the break-even bar fast.
Combined pressure	Revenue falls $10,000, overhead rises $1,000, and variable expenses rise 1 point.	$383,200	$17,200 gap	Two small misses and a margin slip turn near-breakeven into loss.

Can this vehicle repair shop cover its lease, payroll, equipment, and early cash burn before you commit?

Founder checklist

Don’t sign the lease or buy the lifts until Year 1 demand can clear about $36.2K in monthly break-even revenue. At that point, the shop can absorb its fixed load and still leave room for ramp-up risk.

1Demand proof$36.2K/mo

Verify $12K of Year 1 marketing at a $75 CAC can bring about 160 customers and enough booked work to cross monthly break-even.

2Lease load$4.5K rent

Confirm the $4,500 facility rent fits inside the $7.3K monthly non-payroll fixed stack, because rent is the first cost that can squeeze margin.

3Equipment build$152K capex

Verify the $45K diagnostic suite, $30K lifts, $12K tool sets, and $20K alignment system are funded before launch so the bays can actually bill.

4Margin mix72.5% CM

Check that parts, fluids, shop supplies, technician commissions, and inspection fees stay near the 27.5% variable cost plan, or break-even climbs fast.

5Payroll ramp$18.96K/mo

Make sure Year 1 payroll for the owner, lead ASE technician, service advisor, and bookkeeper is covered before adding the junior ASE technician in Month 13.

6Cash cushion$731K / Month 8

Hold enough cash to survive the Month 8 low point, because minimum cash of $731K comes before break-even in Month 9.
