Lunar Base Design Engineering Break-Even: About $191K/Month


This break-even analysis covers a US lunar habitat and infrastructure design firm through the first-year planning model and early ramp-up It uses $1189K in monthly fixed costs, project delivery costs implied by the model, and a contribution margin near 62% It excludes tax advice, valuation, fundraising promises, and launch-provider pricing

Which lunar habitat engineering expenses stay fixed, and which move with project volume?

Cost classification

Break-even only works when fixed overhead and volume-linked expenses are separated cleanly. Here, Month 1 burn includes facility, software, and core payroll before project revenue catches up.

Expense Cost Break-Even Treatment Common Mistake
Secure Facility Lease Fixed Include $12,000 in monthly overhead from Month 1. Treating the lease as project-only.
Engineering Software Subscriptions Fixed Include $15,000 in burn from Month 1. Waiting to budget license renewals.
Principal Aerospace Engineer payroll Fixed Include about $18,333 per month even when underused. Assuming senior payroll flexes with revenue.
Cloud Simulation Compute Costs Variable Model at 8% of first-year revenue. Ignoring heavy simulation runs.
Material Testing Consumables Variable Model at 5% of first-year revenue. Hiding lab usage inside overhead.
Business Development Travel Variable Model at 7% of first-year revenue. Treating proposal travel as optional.
Technical Proposal Labor Variable Model at 5% of first-year revenue. Missing unpaid bid labor.

How does break-even shift from lean to full lunar base engineering scale?

Scenario table

As billable hours rise from 120 to 160 per active customer, pricing steps up and variable cost ratios ease. That moves the business from a lean loss to near break-even in the base case and a stronger cushion in the full case.

Planning assumptions only; actual break-even will move with utilization, subcontracting mix, and project timing.
Scenario Monthly Revenue Variable Costs Fixed Costs CM Ratio Operating Profit Break-Even Signal
Lean launch scale (Year 1) $92.8K $39.2K $114.8K 57.8% -$61.2K Still below break-even; cash burn stays high at this scale.
Base ramp scale (Year 2) $199.9K $68.5K $126.4K 65.7% $5.0K Near break-even; Month 19 is the model's pivot point.
Full delivery scale (Year 5) $516.4K $147.7K $196.4K 71.4% $172.3K Break-even is well covered, but mix and utilization still matter.

What breaks the break-even plan if contracts slip or overhead rises?

Stress test

Year 2 sits just above break-even, so a 10% revenue slip, a 10% overhead jump, or a 5-point margin drop can push it back into loss. Watch delayed billing, higher subcontractor rates, software renewals, and hiring before signed scope.

Stress Case Changed Assumption Break-Even Revenue Revenue Gap Risk Signal
Current plan No change. $1,999K $50K cushion Only a thin cushion remains.
Revenue shortfall Revenue falls 10% because milestone billing slips. $2,087K $88K gap Delayed billing can flip the plan to loss.
Fixed-cost pressure Overhead rises 10% from software renewals and facility costs. $2,081K $82K gap Fixed costs can erase the small cushion.
Margin pressure Contribution margin drops 5 points from higher subcontractor rates. $2,048K $49K gap Pricing and vendor drift matter fast.
Combined pressure Revenue falls 10%, overhead rises 10%, and margin drops 5 points. $2,308K $309K gap Losses compound fast if scope is not signed first.

Can you lock in the lease, hires, and lab build before signed work proves the revenue can carry them?

Founder checklist

Don’t commit to the lease, software, and lab build until signed or near-signed work can support about $191K/month revenue. The model reaches breakeven in Month 19, but cash still bottoms at -$440K in Month 18, so the cash bridge has to be real before you spend.

1Signed Pipeline$191K/mo

Verify signed or near-signed work can cover about $191K per month, or the fixed load will outrun break-even.

2Lease Load$38.5K/mo

Check that the proposal pipeline can carry the $38.5K monthly fixed base, including the $12K lease and $15K software, before you sign.

3Project Margin75% CM

Keep each project above about 75% contribution after cloud compute, materials, travel, and proposal labor, or break-even slips fast.

4Hiring Ramp120-130 hrs

Add the Structural Design Engineer and ISRU Materials Scientist only when active-customer load holds in the 120 to 130 billable hours range and backlog justifies it.

5Cash Cushion-$440K

Fund the Month 18 cash trough, because the model dips to -$440K before breakeven in Month 19.

6Capex Stage$555K

Delay the HPC cluster, server room, test bed, workstations, printer, fitout, encrypted hardware, and lab tools until contract scope truly needs them, because the full build is $555K.
