Break-even calculator

This calculator tests whether monthly revenue covers variable expenses and the fixed cost base.

Monthly revenue Revenue sets the monthly margin available to cover fixed costs. $ Low sales High sales Variable expenses These are direct costs that rise as each job volume rises. $ Low direct cost High direct cost

Cost classification

Your break-even date is only reliable if each expense sits in the right bucket. Treat feedstock and job labor as unit-driven, while lease, software, and insurance stay monthly obligations even when production slips.

Expense	Cost	Break-Even Treatment	Common Mistake
Wire feedstock	Variable	Tie titanium, Inconel, bronze, steel, and specialty alloy wire directly to each part and alloy mix.	Burying metal input inside overhead and overstating margin.
Shielding gas	Variable	Apply argon, helium mix, and standard shielding gas by build type and production volume.	Using one flat monthly gas estimate for all jobs.
Robotic welding labor per build	Variable	Model build labor per job, separate from salaried engineering payroll.	Mixing direct build labor with fixed staff wages.
Advanced Manufacturing Facility Lease	Fixed	Use the $25,000/month lease as a monthly burden from Month 1 through Month 60.	Reducing lease expense when unit volume is low.
Software Enterprise Licenses	Fixed	Carry the $5,500/month license expense as fixed operating overhead.	Spreading the subscription as if it changes per part.
Utilities and High-Speed Connectivity	Semi-variable	Split the base service from the build-hour power load tied to machine use.	Treating all power and connectivity as fixed overhead.
Equipment Maintenance Reserve	Semi-variable	Use the 0.8% model allocation to reflect usage-driven wear plus planned service needs.	Ignoring higher maintenance as production hours rise.
Quality Control Inspector wages	Semi-fixed	Step staffing from 1.0 FTE in the first year to 5.0 FTE by the fifth year as volume rises.	Modeling inspection staff as either fully fixed or per-part labor.

How do lean, base, and full output levels change break-even for this wire arc additive manufacturing service?

Scenario table

Here’s the quick math: higher output spreads shop overhead across more revenue, so break-even gets safer as utilization rises. The catch is execution, because downtime, rework, or slow post-processing can shrink that cushion fast.

Planning cases only; actual results will move with part mix, yield, and machine uptime.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$230.4K	$76.4K	$115.5K	66.8%	$38.5K	Narrow cushion; one weak month can push the shop near break-even.
Base growth case	$827.3K	$260.3K	$174.3K	68.5%	$392.7K	Fixed costs are well covered; this is the first steady run rate.
Full capacity case	$1,550.2K	$479.5K	$220.9K	69.1%	$849.8K	Best cushion, but only if uptime and finishing flow stay reliable.

What breaks the break-even plan if volume or margin slips?

Stress test

This service clears break-even in the base case, but the cushion narrows fast if large jobs slip or overhead climbs. The main warning signs are delayed contracts, rework, scrap, higher wire and gas spend, heavier machining, and longer inspection cycles.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.73M	$575K cushion	Base case clears break-even with room to spare.
Revenue shortfall	Monthly revenue falls 10% while margin holds at 66.8%.	$1.73M	$344K cushion	Lower contract volume cuts the buffer, but profit holds.
Fixed-cost pressure	Fixed costs rise 10% to about $1.27M a month.	$1.90M	$404K cushion	Higher overhead eats cash, so cost control matters.
Margin pressure	Contribution margin falls 5 points to 61.8%.	$1.87M	$435K cushion	Rework, scrap, or higher input spend can squeeze profit fast.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin falls 5 points.	$2.06M	$16K cushion	One more miss could erase profit and push the model back to the line.

Is the shop ready to sign the lease, hire the crew, and order the cell?

Founder checklist

Don’t make the big commitment until signed inquiries can support the break-even run rate and the launch cash gap is covered. For this model, the real test is whether demand, margin, staffing, and equipment timing all work before spending starts.

1Demand proof$173K/mo

Confirm signed inquiries and quotes can reach at least $173K a month, because that is the revenue run rate needed to cover the base shop load.

2Monthly burn$115.5K

Check that the lease, software, insurance, legal, utilities, and core wages stay near $115.5K a month, or the break-even line moves up fast.

3Contribution margin≈76%

Verify the first-year part mix still leaves about 76% contribution after direct costs and the modeled 9% sales, R&D, and shipping load.

4Year 1 volume49 parts

Validate the first-year forecast totals 49 parts across the five SKUs, then stage hiring against that throughput instead of adding headcount too early.

5Cash trough-$563K

Fund the Month 8 low point up front, since the model bottoms at negative $563K and a thin cash plan can break the launch.

6Launch buildout$2.13M

Finish the build-out, power upgrade, machine acceptance, and wire-to-inspection workflow before launch spending, because the capex plan totals $2.13M.
