This break-even analysis covers a US preventive conservation service over a five-year model period, with first-year break-even revenue near $561K per month It includes fixed and variable expenses, contribution margin, monthly overhead, and launch risk, but excludes tax planning, grant forecasting, and one-time capital purchases unless modeled separately

Which preventive conservation service expenses are fixed, and which move with sales?
Cost classification
Break-even is only useful if fixed overhead is separated from delivery spend. In the first operating year, rent and insurance sit in the monthly nut, while materials at 8.5% and travel at 12.0% of revenue move with jobs.
Expense
Cost
Break-Even Treatment
Common Mistake
Lab and Office Rent
Fixed
Use $6,500 per month in fixed overhead from Month 1 through Month 60.
Allocating rent to each project and hiding the monthly break-even burden.
Professional Liability Insurance
Fixed
Use $1,200 per month as a recurring fixed charge regardless of job count.
Dropping insurance from break-even because it is not tied to delivery hours.
Utilities and Climate Control
Semi-fixed
Start with the $1,100 monthly base, then step it up when lab capacity or climate-controlled space expands.
Treating climate control as fully variable just because usage rises with activity.
Vehicle Maintenance and Fuel
Semi-variable
Keep the $950 monthly base in overhead and track added trip fuel against field work.
Putting all vehicle spend in fixed overhead and missing travel-heavy project drag.
Archival Materials and Supplies
Variable
Model as 8.5% of first-year revenue, then use the forecast rate for each later year.
Using one flat dollar amount even when project volume changes.
Laboratory and Testing Fees
Variable
Model as 4.5% of first-year revenue because testing rises with conservation work delivered.
Classifying testing as fixed lab overhead instead of job-linked spend.
Field Travel and Lodging
Variable
Model as 12.0% of first-year revenue and update as the mix of on-site work changes.
Averaging local and remote projects into one margin assumption.
Conservation and Support Payroll
Semi-variable
Year 1 payroll is $287,500 annually; keep core roles fixed and add hiring only when utilization supports it.
Treating all payroll as fixed and hiring ahead of billable demand.
How does break-even shift from a lean launch to a base year and a full operating case for preventive conservation services?
Scenario table
As recurring contracts rise from 45% in Year 1 to 65% in Year 5, contribution grows faster than overhead. That shifts the model from a Year 1 loss to a Year 3 cushion and a stronger Year 5 profit.
Planning figures only; actual break-even will move with contract mix, staffing, and travel load.

What pushes a preventive conservation service below break-even?
Stress test
Year 1 revenue sits below break-even, so there isn’t much cushion. Fewer museum contracts, travel above 12%, or delayed collections-care staffing will widen the gap fast.

What should you verify before you lock the lease, hires, vehicle, and equipment?
Founder checklist
Do not lock fixed overhead until signed or late-stage museum work can cover the modeled $561K monthly break-even revenue. Year 1 revenue is $503K and EBITDA is -$165K, so the gap is still real.
1Pipeline cover$561K/mo | 45% mix
Verify signed and late-stage museum work can cover the modeled break-even revenue, with annual service contracts making at least 45% of Year 1 revenue.
2Base load$12.1K/mo
Hold rent, professional liability insurance, software, utilities, admin, and vehicle costs near the modeled $12.1K a month, and test whether travel plus lodging stays inside the 12% budget.
3Rate card71% CM
Price against $185/hr contracts, $215/hr project work, and $250/hr consulting, then keep direct costs near 29% of revenue so billed hours fund overhead.
4Staffing ramp$287.5K payroll
Do not add the business development manager or extra technicians until the 3.5 FTE base and 12.5 billable hours per active customer per month can hold.
5Cash floor$542K floor
Keep cash above the modeled $542K minimum through Month 26, because breakeven lands at Month 22 and payback still runs to 51 months.
6Launch CAC$45K | $2.5K CAC
Use the $45K Year 1 marketing budget only if CAC stays near $2,500, or launch spend will outrun early revenue.
