Cost classification

Your break-even only works if fixed overhead, unit inputs, and revenue-based fees stay in separate buckets. Treat the $5,800 monthly power line as fixed, but keep processing, freight, commissions, and compliance allocations tied to revenue or volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Industrial Facility Lease	Fixed	Include $18,500 per month in fixed overhead before calculating break-even revenue.	Spreading rent across units and overstating contribution margin.
Certification Maintenance Fees	Fixed	Include $3,500 per month as a recurring operating commitment from Month 1.	Ignoring certification upkeep because it isn’t tied to one job.
Utilities and Compressed Air Power	Fixed	Model $5,800 per month as fixed within the current planning range.	Moving all power spend with units instead of separating base plant load.
NADCAP Compliance Audit Allocation	Variable	Treat as revenue-linked: 1.0% to 1.5% of revenue depending on part category.	Burying aerospace compliance inside generic overhead.
Energy Intensive Processing	Variable	Apply the revenue percentage by part category; first-year rates range from 1.0% to 2.0%.	Counting the $5,800 utility line but missing usage-linked processing charges.
Unit Inputs	Variable	Apply per-unit inputs like media, Almen strips, sensors, nozzle wear, masking tape, and direct tech labor.	Using one blended materials rate across turbine disks, pins, gears, shafts, and implants.
Shipping and Specialized Freight	Variable	Apply 4.5% of first-year revenue and 3.5% by the mature year.	Treating specialized freight as office overhead instead of a sales-linked charge.
Robotics Technician Staffing	Semi-fixed	Model in staffing steps as headcount rises from 2.0 FTE in the first year to 6.0 FTE in Year 5.	Scaling technician payroll perfectly with each unit instead of capacity jumps.

How does break-even change from a lean year to base and full capacity?

Scenario table

Break-even gets easier as contribution dollars rise faster than fixed payroll and facility costs. All three cases stay positive here, but the cushion is small in lean and much wider by full capacity.

Planning assumptions only; these scenario figures are not a guarantee of sales.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean first-year ramp	$269k	$85k	$89k	68.2%	$94k	Positive, but the cushion is modest.
Base Year 3 operating case	$420k	$104k	$121k	75.1%	$194k	Fixed costs are covered comfortably, so risk drops.
Full-capacity Year 5 case	$638k	$155k	$135k	75.8%	$348k	Largest cushion here; break-even risk is lowest.

What breaks the break-even plan for this shot peening service?

Stress test

Here’s the quick math: about $89k in monthly fixed load divided by a roughly 70% contribution margin gives about $127k/month break-even. The cushion narrows fast if customer qualification slips, overhead rises, or overtime and media costs push margin down.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$127k/month	$142k cushion	There is cushion, but launch timing still matters.
Revenue shortfall	Revenue lands 20% below plan at about $215k per month.	$127k/month	$88k cushion	Slow customer qualification trims the safety buffer.
Fixed-cost increase	Fixed overhead rises 15% to about $102k per month.	$146k/month	$123k cushion	Low utilization leaves rent and labor harder to cover.
Margin pressure	Contribution margin drops 5 points, from about 70% to 65%.	$137k/month	$132k cushion	Overtime and media inflation hit gross profit fast.
Combined pressure	Revenue is down 45%, fixed overhead is up 15%, and margin falls to 65%.	$158k/month	$10k gap	A slow ramp plus cost pressure can flip the month red.

Can this shot peening shop clear break-even before you sign the lease and buy the equipment?

Founder checklist

Only move if booked work can cover the Month 2 break-even line and the opening build can carry the cash dip in Month 6. This model needs both demand and funding in hand before the lease is signed.

1Pipeline depth$268.8K/mo

Verify the booked pipeline can support the Year 1 average monthly run-rate, not just a short opening spike.

2Break-even cover$127K/mo

Get signed or near-signed work above the monthly break-even line before you commit to the lease and major equipment cash.

3Fixed burn$89.1K/mo

Make sure the shop can carry the fixed overhead and the Year 1 salaried team before volume fully ramps.

4Unit margin79%-92%

Check that the lowest-price work, including $45 transmission gears, still leaves room after direct cost and built-in quality, compliance, and control costs.

5Throughput2,350/mo

Confirm operators can process about 2,350 parts a month at the Year 1 mix without rework or inspection delays.

6Cash floor$463K

Hold enough funding to cover the $1.42M buildout and still keep the Month 6 minimum cash cushion intact.
