Cost classification

For this consultancy, break-even is reliable only if monthly overhead stays separate from percentage-based costs. Bad labels break the break-even point: fixed items like $6,500 rent sit in overhead, while 12.0% travel is deducted before contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $6,500 per month in fixed overhead for the break-even calculation.	Treating rent as project-linked and understating required monthly billings.
Insurance	Fixed	Include $1,200 per month in fixed overhead before calculating required contribution.	Dropping insurance from overhead because it does not tie to one client job.
Legal & Accounting Services	Fixed	Include $2,200 per month in fixed overhead across the active operating period.	Modeling recurring advisory fees as occasional spend and overstating early profit.
Travel & On-Site Expenses	Variable	Deduct 12.0% of first-year revenue before contribution margin because site work rises with projects.	Treating travel as fixed when more audits and implementations mean more trips.
Marketing & Business Development	Variable	Deduct 8.5% of first-year revenue before contribution margin to reflect proposal and sales activity.	Holding proposal spend flat while assuming more client wins.
Professional Development & Training	Variable	Deduct 2.8% of first-year revenue before contribution margin, since delivery depth grows with billable work.	Leaving training in fixed overhead even as project scope and technical demands rise.
Software Licensing & Technology	Semi-variable	Deduct the 3.5% first-year revenue charge, and track added seats or project tools as client count grows.	Assuming one software bill covers every new client and every added engineer.
Senior Industrial Engineer Payroll	Semi-fixed	Add payroll to fixed overhead as capacity steps up: 0.5 FTE in the first year, then 1.0 FTE after that.	Spreading salary smoothly across revenue instead of modeling the hiring step.

How does break-even shift from a lean founder-led launch to a fully staffed methods engineering consulting practice?

Scenario table

Lean breaks even with a much smaller revenue base because fixed costs stay light. Base adds delivery capacity and still clears break-even, while full staffing raises payroll and the revenue bar fast.

Planning assumptions only; actual results will move with pricing, utilization, travel, and hiring pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean founder-led launch	$34,800	$9,326	$25,480	73.2%	$0	Basically at break-even; a small miss turns it negative.
Base early-team case	$102,400	$27,443	$30,688	73.2%	$44,269	Healthy cushion here; revenue sits well above break-even.
Full Year 4 staffed practice	$623,250	$138,995	$77,980	77.7%	$406,275	Strong cushion, but payroll keeps the break-even bar much higher.

What breaks the break-even plan if revenue slips or costs creep up?

Stress test

The base plan has a solid cushion, but it shrinks fast if client starts slip or overhead rises. The main risk is a short revenue delay while fixed payroll and travel stay in place.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$41,900	$60,500 cushion	Healthy cushion, but only if starts land on time.
Revenue shortfall	Monthly revenue drops 20% to about $81,900.	$41,900	$40,000 cushion	Still above break-even, but the cushion drops fast.
Fixed-cost pressure	Fixed costs rise 15% to about $35,300.	$48,300	$54,100 cushion	Overhead creep lifts the monthly break-even line.
Margin pressure	Variable expenses rise to 318%, so contribution margin falls.	$45,000	$57,400 cushion	Travel, on-site work, or rework can erode cash fast.
Combined pressure	Revenue is 50% lower, fixed costs are 15% higher, and variable expenses stay at 318%.	$51,700	$500 gap	A small pipeline miss turns the month into an operating loss.

Can this consulting team cover break-even before you lock the office lease and hire ahead of demand?

Founder checklist

Do not commit to rent, hires, software, or travel until the signed pipeline can cover about $41.9K in monthly break-even revenue. The model reaches break-even in Month 4, so the first test is whether current work already fills that gap.

1Break-even revenue$41.9K/mo

Confirm signed work and near-term proposals can reach this monthly run rate before you add fixed cost.

2Active clients7 accounts

Validate about 7 active customers at 32 hours each, because that mix gets you to roughly 224 billable hours and keeps revenue from leaning on one buyer.

3Billable load220 hrs/mo

Check that the team can sustain about 220 billable hours a month at a $191 weighted average rate, and keep the Senior Industrial Engineer at 0.5 FTE until demand supports more.

4Contribution margin73.2%

Verify variable spend stays near 26.8% of revenue, because that leaves the margin needed to cover payroll and fixed overhead.

5Lease load$6.5K/mo

Delay the office lease if client-site work can start remotely, since rent is the easiest fixed cost to avoid before break-even is real.

6Cash cushion$746K min

Keep enough cash for the Month 2 low point, because the model shows the worst cash balance before break-even lands in Month 4.
