Which mobile gaming PC sales expenses are fixed, variable, semi-variable, or semi-fixed?

Cost classification

Break-even is reliable only when monthly overhead, per-sale costs, and staffing steps stay separate. Here, fixed overhead starts near $29,700 per month before payroll, while hardware at 14.0% and shipping/payment at 5.5% move with first-year revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Direct Hardware Acquisition Costs	Variable	Use 14.0% of first-year revenue, stepping down to 12.0% by the mature year.	Treating the initial $150,000 inventory stocking as normal monthly overhead.
Shipping and Payment Processing	Variable	Apply 5.5% of first-year revenue, improving to 4.7% as order volume scales.	Modeling payment fees and shipping as fixed platform charges.
E-commerce Infrastructure and Hosting	Fixed	Include $4,500 per month from Month 1 through Month 60 in fixed overhead.	Mixing the one-time platform development spend into monthly hosting.
Marketing and Brand Partnerships	Fixed	Include $12,000 per month as planned operating overhead.	Assuming all marketing rises with each order when the model sets a monthly budget.
Warehouse and 3PL Management Fees	Fixed	Include $6,500 per month for third-party logistics (3PL) management fees.	Treating the full warehouse line as per-unit fulfillment expense.
Technical Support Specialist Payroll	Semi-fixed	Add payroll in staffing steps: 1.0 FTE in the first year, rising to 5.0 FTE by the mature year.	Averaging support payroll per order instead of adding staff when capacity breaks.
Content Creation and Benchmarking Lab	Fixed	Include the recurring $3,000 per month lab and content expense in overhead.	Blending recurring lab operations with the one-time lab setup spend.

How does break-even change from a lean launch to full scale for mobile gaming PC sales?

Scenario table

Break-even improves as revenue scales because variable costs drop from 19.5% of sales in Year 1 to 16.7% in Year 5, so margin coverage widens. Fixed payroll still rises, so the cushion grows, but not without added staffing pressure.

Planning assumptions, not guarantees; actual break-even will shift with product mix and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch (Year 1)	$305.1K	$59.5K	$59.7K	80.5%	$185.9K	Positive, but this has the thinnest cushion.
Base case (Year 3)	$1,276.3K	$231.5K	$76.8K	81.9%	$967.9K	Strong cushion; scale is covering overhead faster than payroll grows.
Full scale (Year 5)	$4,663.7K	$778.4K	$100.1K	83.3%	$3,785.2K	Very wide cushion, though support staffing keeps fixed costs climbing.

What breaks the break-even plan for this mobile gaming PC business?

Stress test

The plan has a wide opening-year cushion, but it gets thin fast if conversion slips, overhead creeps up, or shipping and payment fees rise. In Year 1, average monthly revenue is about $305.1k versus a $74.2k break-even line.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$74.2k	$230.9k cushion	Strong cushion, but fixed spend still needs steady conversion.
Revenue shortfall	Monthly revenue runs 20% below plan.	$74.2k	$169.9k cushion	Lower traffic or weaker close rates trim headroom fast.
Fixed-cost increase	Fixed overhead rises by $10k per month.	$86.6k	$218.5k cushion	Extra marketing, support, or warehousing spend raises the bar immediately.
Margin pressure	Shipping and payment fees rise by 1 point.	$75.1k	$230.0k cushion	Discounting and fee creep push break-even up even if sales hold.
Combined pressure	Revenue falls 20%, overhead rises $10k, and margin drops 1 point.	$87.7k	$156.4k cushion	When traffic, fees, and overhead all move the wrong way, the cushion shrinks hard.

Can this mobile gaming PC business clear its fixed base before you commit to inventory and staff?

Founder checklist

Test the sales plan against the $59.7K monthly fixed load and the $820K cash floor before you sign for inventory or staff. If the opening run can’t cover that burn, wait on bigger commitments.

1Demand proof$305K/mo

Confirm live traffic can support about $305K a month in Year 1, and do not add showroom-like commitments until that demand is real.

2Fixed load$59.7K/mo

Keep the monthly overhead and payroll base at this level or lower, because fixed spend has to be covered before growth feels safe.

3Contribution80.5% CM

Year 1 variable cost is 19.5% of sales, so each dollar keeps 80.5 cents to cover fixed costs and profit.

4Payroll timing$360K/yr

Year 1 already assumes $360K of salaries, so tie hiring to paid orders instead of launch excitement.

5Cash cushion$820K min

Keep cash above the $820K floor, because Month 2 is the low point and the model needs room for setup and inventory spend.

6Stock terms$150K order

Verify supplier payment timing and return terms before the $150K opening inventory order, since that cash leaves early and support costs come right after.
