Which expenses are fixed, and which move with charging sales?

Cost classification

Break-even is reliable only when monthly overhead stays separate from spend tied to revenue or acquisition. Fixed overhead is $40,200/month before payroll, while processing, cloud, support, and coverage percentages rise with sales.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent ($12,000/month)	Fixed	Carry it as monthly overhead from Month 1 through Month 60.	Spreading rent as a percentage of sales.
Software Licensing & Tools ($8,500/month)	Fixed	Include it in the base monthly burn before contribution margin.	Assuming software drops when orders slow.
Payment Processing Costs (8.5% of first-year revenue)	Variable	Apply it directly against each dollar of platform revenue.	Modeling processing fees as flat overhead.
Cloud Infrastructure Costs (6.5% of first-year revenue)	Variable	Treat usage as revenue-linked because the model expresses it as a percentage.	Locking cloud spend at one monthly number.
Customer Support & Operations (12.0% of first-year revenue)	Variable	Deduct it in contribution margin before testing break-even volume.	Counting support only as salaried overhead.
Insurance & Liability Coverage (4.5% of first-year revenue)	Variable	Scale it with revenue, separate from fixed business insurance.	Combining it with the $4,200/month policy.
Seller and buyer marketing budgets ($350,000 in first year)	Semi-variable	Split committed launch spend from acquisition spend that scales with customer adds.	Treating the full budget as pure customer acquisition spend.
Payroll team plan ($887,500 in first year; about $73,958/month)	Semi-fixed	Add headcount in steps as capacity needs rise, not per order.	Ignoring new staffing blocks after early growth.

How do lean, base, and full utilization scenarios change the break-even point for mobile EV charging?

Scenario table

All three cases keep a roughly 68% contribution margin, so break-even is mostly a volume test against $143K fixed costs. Lean stays about $43K short, base lands at break-even, and full adds about $43K of cushion.

These are planning assumptions built from the model inputs, so they show direction and risk, not a guaranteed result.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean route-density case	$146K	$46K	$143K	68.5%	-$43K	Still below break-even; route density needs work.
Base launch case	$209K	$66K	$143K	68.4%	$0	Hits break-even, so small misses turn into loss.
Full utilization case	$272K	$86K	$143K	68.4%	$43K	Clear cushion; repeat usage and fleet mix matter most.

What breaks the break-even plan for mobile EV charging?

Stress test

Break-even sits at about $209K of revenue, so the plan has little room for error. If utilization slips, variable costs rise, or overhead climbs, the model moves from near-balance to a low-five-figure gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$209K	$0 cushion	At plan, the cushion is basically gone.
Revenue shortfall	Revenue falls 15% to $178K.	$178K	$22K gap	Lower utilization leaves fixed costs uncovered.
Fixed-cost increase	Overhead rises 10% from $143K to $158K.	$209K	$14K gap	Any overhead step-up cuts the cushion fast.
Margin pressure	Variable expenses rise from 31.5% to 36.5% of revenue.	$209K	$11K gap	Route inefficiency or downtime erodes contribution.
Combined pressure	Revenue falls 15% to $178K, overhead rises 10%, and variable expenses rise to 36.5%.	$178K	$45K gap	A softer launch with higher costs burns cash fast.

What should you verify before you commit to vehicles, chargers, and the first territory?

Founder checklist

Don’t lock in vehicles, chargers, or territory leases until the order flow and unit economics are proven. The model needs dense demand, a Year 1 acquisition budget near $350K with CAC at $45 and $850, and enough cash to absorb the $875K Year 1 EBITDA loss and the Month 17 trough.

1Territory volume$209K/mo

Prove a dense route before you sign long-term leases, because the model only works if monthly revenue can reach about $209K and the $45 buyer CAC and $850 seller CAC still support the Year 1 acquisition budget.

2Base overhead$40.2K/mo

Keep the core overhead at $40.2K per month, because the model is already planning for a Year 1 EBITDA loss of $875K before scale.

3Contribution margin68.5% CM

Verify that processing, cloud, support, and insurance still total 31.5% of revenue, so gross contribution stays at 68.5% and can cover the fixed load.

4Equipment fitMonth 1-11

Test the portable charger, mapping, payment, and dispatch stack in Months 1-11 before scaling, because bad compatibility breaks response-time promises and slows repeat use.

5Hiring ramp1→12 FTE

Add ops, support, sales, and finance only when orders justify them, since the model ramps from 1 to 12 FTE and hiring too early crushes utilization.

6Cash runway-$764K

Hold cash for the Month 17 low point, because minimum cash falls to -$764K and payback takes 32 months.
