Cost classification

Break-even is only useful if fixed overhead, unit build costs, and step-up staffing stay in the right buckets. Misclassifying payroll or warranty costs can make Month 1 break-even look cleaner than the actual cash burden.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Rent	Fixed	Include $5,000 per month in fixed overhead through Month 60.	Allocating rent to each scooter and muddying unit margin.
Website Hosting & Software Licenses	Fixed	Include $1,500 per month before calculating required contribution margin.	Treating platform spend as volume-driven when it is stable.
Urban Commuter Unit Build	Variable	Subtract $100 per unit for battery, motor, frame, controls, and direct assembly labor.	Burying direct build labor inside general payroll.
Shipping & Logistics	Variable	Model as 5.0% of first-year revenue, falling to 3.0% by the mature year.	Entering the percentage as a flat monthly amount.
Payment Processing & Platform Fees	Variable	Deduct 2.5% of first-year revenue, then update by year as rates decline.	Ignoring fees when testing contribution margin.
Warranty Provision	Semi-variable	Accrue by model mix, from 0.4% to 1.0% of revenue depending on scooter type.	Treating warranty as fixed overhead instead of sales-linked risk.
Quality Assurance Overhead	Semi-variable	Apply the revenue-linked quality allowance, ranging from 0.7% to 1.2% by model.	Leaving quality checks out of break-even math.
Assembly, Warehouse, and Support Staffing	Semi-fixed	Step payroll up as forecast volume rises, including technicians, warehouse assistants, and support roles.	Burying payroll inside unit margin instead of modeling capacity steps.

How does break-even change from a lean Year 1 launch to a full Year 5 build?

Scenario table

You're above break-even in all three cases. The cushion widens as revenue scales faster than fixed shop and staff costs, so the full mix is safer than the lean launch.

Planning case figures reflect model assumptions, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean case: Year 1 mix	$440k	$86.3k	$47.8k	80.4%	$305.9k	Already profitable, but the cushion is the smallest.
Base case: Year 3 mix	$957.2k	$174.5k	$59.5k	81.8%	$723.2k	Comfortable cushion if the Year 3 mix holds.
Full case: Year 5 mix	$1.40M	$224.8k	$59.5k	84.0%	$1.12M	Strong cushion, but it depends on supplier and assembly capacity.

What breaks the break-even plan for custom E-scooter sales?

Stress test

At the Year 1 plan, the business keeps a strong cushion, but battery cost spikes, controller shortages, warranty claims, and paid acquisition can close that gap fast. The main test is whether contribution stays well above fixed overhead.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$731K	$4.55M cushion	Base case covers overhead with room to spare.
Revenue shortfall	Year 1 revenue runs 15% below forecast.	$731K	$3.76M cushion	Demand softens, but overhead still clears.
Fixed-cost pressure	Fixed overhead rises 10% from the plan.	$803K	$4.48M cushion	Extra warehouse or staff cost narrows the buffer.
Margin pressure	Variable burden rises from 19.6% to 21.6%.	$749K	$4.53M cushion	Battery, controller, or warranty cost inflation hits first.
Combined pressure	Revenue is 15% lower, fixed overhead is 10% higher, and variable burden is 21.6%.	$824K	$3.66M cushion	Three hits at once still work, but the cushion shrinks fast.

What should you verify before you lock in warehouse space and launch custom e-scooter production?

Founder checklist

Don’t lock in the lease, hires, or equipment until the first-year mix, supplier quotes, and cash need all line up. This model shows about $43.2K a month of fixed load and a $1.158M minimum cash need, so break-even has to hold before you spend.

1Supplier quotes$78-$270 BOM

Confirm quotes, minimum order quantities, and lead times for batteries, motors, frames, electronics, and cargo parts, because that range drives your build cost and order timing.

2Demand proof3,400 units

Test paid ads and preorder interest against the 3,400-unit first-year mix before you scale spend, or you can buy inventory too early.

3Fee stack7.5%

Verify shipping at 5.0% and payment processing at 2.5% stay close to plan, since fee drift cuts the margin that funds overhead.

4Warranty reserve0.4%-1.0%

Set reserve by model line, not one blended rate, because warranty needs run from 0.4% to 1.0% across the product mix.

5Assembly flow6.0 FTE

Map the build steps before hiring, because Year 1 already uses 6.0 FTE and the line will stall if roles are not clear.

6Runway$43.2K/mo

Keep the $1.158M minimum cash need visible and stage the $150K assembly line, $80K configurator, and $30K testing gear before a bigger rollout.
