Cost classification

Break-even is reliable only when steady overhead stays separate from job-linked spend. With break-even in Month 6, misclassifying payroll, materials, or capacity spend can make the target look easier than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Storage unit and small office, $1,200/month	Fixed	Include in monthly overhead before calculating required contribution.	Spreading it across jobs and hiding the true monthly nut.
Business liability insurance, $250/month	Fixed	Treat as a steady operating charge from Month 1 through Month 60.	Dropping it when job volume is low.
Safety fixture wholesale costs, 18% of first-year revenue	Variable	Apply as a percentage of revenue because fixture spend rises with completed jobs.	Budgeting a flat monthly amount despite higher installation volume.
Installation consumables and hardware, 4% of first-year revenue	Variable	Deduct from each revenue dollar before contribution margin.	Ignoring anchors, fasteners, and small parts in job margin.
Fuel and vehicle maintenance, 5% of first-year revenue	Variable	Model as sales-linked travel expense tied to service calls.	Treating route mileage like fixed overhead.
Referral partner commissions, 3% of revenue	Variable	Subtract only when referred revenue is earned.	Counting commissions as overhead even when no referred job closes.
Staffing: owner operator, technicians, coordinator, outreach role	Semi-variable	Model payroll by full-time equivalent levels as headcount changes by year.	Using one flat payroll number while technician capacity expands.
Marketing budget, $12,000 in the first year	Semi-fixed	Treat as planned capacity spend that steps up with growth targets.	Treating van purchases, tools, and setup spend as monthly operating overhead.

How does break-even change across lean, base, and fuller schedules for this grab bar installation business?

Scenario table

Break-even is tight in the lean start because fixed overhead eats most of the margin. By Year 1 and Year 2, higher revenue turns the same 70% to 71% contribution margin into a real cushion, but only if routes stay dense and leads convert.

Planning cases only; actual results can move with lead flow, pricing, and crew utilization.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening-month case	$22.7k	$6.8k	$15.9k	70%	$0.0k	Break-even is fragile; one slow month can turn red.
Base Year 1 case	$30.5k	$9.2k	$16.8k	70%	$4.5k	Modest cushion, but route density and quoting discipline still matter.
Full Year 2 schedule	$59.3k	$17.3k	$25.0k	70.9%	$17.0k	Better crew loading and referral flow give this case a stronger cushion.

What breaks the break-even plan for this grab bar installation service?

Stress test

The base case clears break-even, but the cushion gets thin fast if booked work slows, overhead rises, or variable costs creep up. Watch weak referrals, long drive times, low bundle attach rates, and paid leads above the $120 CAC assumption.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$227k	$78k cushion	Base case stays above break-even.
Revenue shortfall	Year 1 revenue falls 15% to $259k.	$227k	$32k cushion	Less room for delays or weak referrals.
Fixed-cost increase	Add $2k of overhead to fixed monthly costs.	$255k	$50k cushion	Back-office creep eats the surplus.
Margin pressure	Variable expenses rise from 30% to 35%, cutting contribution margin to 65%.	$244k	$61k cushion	Travel and lead costs move break-even up.
Combined pressure	Revenue falls to $259k, variable expenses rise to 35%, and fixed costs reach $179k.	$270k	$11k gap	A few misses push the plan below break-even.

Can you clear break-even before you buy the van and hire more help?

Founder checklist

Don’t commit to the van, recurring ads, or extra staff until the customer flow, margin, and cash cushion all clear the break-even test. The business only works if assessments stay steady, conversion holds, and early overhead stays tight.

1Assessed volume37/mo

Verify you can book at least 37 assessed customers a month, with about 85% converting to installation and Year 1 revenue near $610 per customer, before the $227K operating break-even test looks real.

2Job margin70% CM

Quote jobs so fixture wholesale stays at 18% and consumables at 4%, while fuel and referral costs stay near 5% and 3%, because that leaves the margin that pays fixed overhead.

3Overhead base$2.3K/mo

Keep recurring overhead near the $1,200 storage unit, $250 insurance, $150 software, $100 licensing, $200 telecom, and $400 accounting base, and keep the $63K startup spend separate.

4Staffing rampMonth 6

Do not add junior or office staff ahead of the Month 6 break-even timing; the owner and lead technician need enough slack to cover demand before payroll scales.

5Cash cushion$824K

Make sure reserves can absorb the Month 2 cash low, plus the van, tools, inventory, website, and training spend, because the model’s minimum cash lands at $824K.

6Lead mix$1K/mo

Line up referral sources before you rely on paid marketing, because the $1,000 monthly ad budget and $120 CAC should support demand, not carry it alone.
