Which expenses are fixed and which move with sales in a wearable tech design studio?

Cost classification

Break-even only works when studio overhead stays separate from per-project spend. In the first year, fixed monthly overhead starts at $11,000 before salaries, while project-linked costs move with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Studio Rent	Fixed	Use $6,500 per month in fixed overhead from Month 1 through Month 60.	Treating rent as project-driven and overstating margin on slow months.
Core Software Licenses	Fixed	Use $1,200 per month as baseline operating overhead.	Allocating the full license bill only to large client projects.
Utilities & Internet	Fixed	Use $800 per month in the fixed break-even base.	Ignoring small recurring bills because they look immaterial alone.
Lead Industrial Designer, Senior UX/UI Designer, and Senior Mechanical Engineer salaries	Fixed	Include the first-year core team salaries as fixed capacity cost.	Modeling senior staff as variable labor tied to each booked project.
Prototyping Materials & Consumables	Variable	Apply 6.0% of first-year revenue, falling to 4.0% by the mature year.	Burying prototype rework in overhead instead of charging it to project economics.
Project-Specific Travel & Client Meetings	Variable	Apply 8.0% of first-year revenue, falling to 6.0% by the mature year.	Forgetting that client visits rise with active project volume.
External Design Tool Subscriptions	Variable	Apply 5.0% of first-year revenue, falling to 3.0% by the mature year.	Putting scalable project tools into fixed software overhead.
Project Manager starting Month 13	Semi-fixed	Add the $95,000 annual role when operating scale reaches the second year.	Spreading the hire across Month 1 and hiding the capacity step.

How does break-even shift across lean, base, and full wearable design models?

Scenario table

The fuller the team, the higher the monthly revenue floor, even when contribution margin improves. Lean breaks even with the least load; full needs the most stable demand.

Planning assumptions only; actual break-even will move with project mix, retainer share, staffing pace, and travel or tooling spend.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean wearable design studio	$595k	$131k	$464k	78.0%	$0	Lowest overhead, so break-even is the easiest to hold.
Base wearable design studio	$852k	$173k	$679k	79.7%	$0	This is the midpoint case; revenue slips here start to matter fast.
Full wearable design studio	$1.032M	$155k	$877k	85.0%	$0	Highest fixed load, so it needs the steadiest demand to stay safe.

What pushes the wearable tech design plan past break-even?

Stress test

The plan is tight even at the base case: $595K break-even revenue against $464K fixed costs and 78% contribution margin. Delayed client starts, prototype rework, contractor overruns, and software creep can quickly turn that cushion into a gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$595K	$0 gap	Break-even leaves no room for a slow launch.
Revenue shortfall	Revenue lands 15% below plan at $506K.	$595K	$69K gap	A sales miss this size cuts through the operating cushion.
Fixed cost pressure	Overhead rises 10% to $511K.	$655K	$47K gap	Studio and payroll creep lift the break-even bar fast.
Margin pressure	Variable expenses rise from 22% to 27%, cutting margin to 73%.	$636K	$30K gap	Prototype rework and software creep eat contribution.
Combined pressure	Revenue falls 15%, overhead rises 10%, and margin drops to 73%.	$699K	$141K gap	Delayed starts plus overruns push the model into a deep loss.

What should a wearable tech design founder verify before committing to the studio, hires, and prototype spend?

Founder checklist

Run the math before you sign the lease or add staff. With about $44.3K in monthly fixed cost and a 22% variable load, break-even lands near $56.8K in monthly revenue, so the real test is whether booked work can clear that by Month 5.

1Pricing proof$14.4K/project

Verify Year 1 pricing at 80 hours times $180 per hour, or the core design work will not carry the fixed load.

2Fixed load$44.3K/mo

Verify studio rent, software, overhead, and the three core salaries stay inside the revenue path you can actually book.

3Variable load78% CM

Verify total variable costs stay near 22% of revenue, with prototype materials at 6% and travel plus tool subscriptions filling the rest.

4Hire timingMonth 13

Delay the project manager and business development hires until pipeline volume can support the added fixed cost.

5Cash cushion$765K

Verify opening cash can cover the Month 2 low point and the $152K launch capex before payback starts.

6Break-even pathMonth 5

Verify signed work and client-billed prototype jobs can reach break-even by Month 5, and keep internal R&D separate so the signal stays clean.
