Which bike storage retail expenses are fixed, and which move with sales?

Cost classification

The Month 25 break-even only holds if product, fulfillment, and payment fees reduce contribution as sales grow. Treat stable monthly overhead separately, so the model doesn’t overstate margin on first-year revenue of $276,000.

Expense	Cost	Break-Even Treatment	Common Mistake
Product Procurement and Manufacturing	Variable	Use 8.5% of first-year revenue as direct product expense.	Treating inventory buys as fixed overhead.
Import Duties and Freight Inbound	Variable	Use 2.5% of first-year revenue as landed product expense.	Ignoring freight and duty inside gross margin.
3PL Fulfillment and Packaging	Variable	Use 5.5% of first-year revenue for outsourced pick, pack, and ship support.	Leaving packing and fulfillment out of contribution.
Payment Processing and Platform Fees	Variable	Use 3.3% of first-year revenue before calculating contribution margin.	Using gross sales as contribution.
Showroom and Office Rent	Fixed	Model $3,200 per month from Month 1 through Month 60.	Adding space before demand is proven.
E-commerce Platform Subscription	Fixed	Model $450 per month as recurring operating overhead.	Burying platform fees in admin.
Marketing Budget	Semi-variable	Use $45,000 in the first year; at $25 CAC, that implies about 1,800 new customers.	Treating paid acquisition as free growth.
Customer Success Specialist Payroll	Semi-fixed	Model 0.5 FTE in the first year, then step up with support volume.	Hiring ahead of order volume.

How does break-even change across lean, base, and full launch cases for bike storage sales?

Scenario table

Break-even moves with payroll and marketing more than product margin. The lean case stays under pressure, the base case is still short, and the full launch finally covers the fixed load once sales volume is high enough.

Planning scenarios only; actual results can shift with mix, pricing, and overhead.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch, home storage mix	$23,000	$4,554	$23,155	80.2%	-$83,000	Still short of break-even, so keep spend tight.
Base launch, added B2B sales	$42,100	$8,041	$31,280	80.9%	-$15,000	Near break-even, but payroll keeps it in the red.
Full launch, broader mix and volume	$72,800	$13,468	$35,238	81.5%	$227,000	Above break-even with cushion for slower months.

What pushes this bike storage plan below break-even?

Stress test

The plan is tight if conversion slips, freight or fulfillment costs rise, or discounting picks up on facility orders. A 10% revenue miss, a 10% overhead hike, or heavier variable costs each push break-even higher; together they leave about a $9,900 monthly gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$23,000	$0 cushion	Base case sits at the planned monthly sales level.
Revenue shortfall	Monthly sales fall 10% from $23,000 to $20,700.	$23,000	$2,300 gap	Lower conversion quickly burns through the cushion.
Fixed-cost pressure	Monthly fixed costs rise 10% from $23,155 to $25,471.	$31,800	$8,800 gap	Overhead creep pushes break-even far above early sales.
Margin pressure	Variable expenses rise by 5 points from freight, fulfillment, and payment fees.	$30,800	$7,800 gap	Higher inbound and handling costs squeeze each sale.
Combined pressure	Sales drop 10%, fixed costs rise 10%, and variable costs stay elevated.	$32,900	$9,900 gap	Multiple hits together create a clear monthly cash drain.

Can you prove demand, margin, and cash hold before you commit to inventory and showroom rent?

Founder checklist

Don't lock in inventory, showroom rent, or new hires until the first-year math holds in live orders. If CAC stays near $25, blended AOV stays near $151, and variable cost stays near 19.8%, the path to Month 25 break-even is credible.

1Demand Proof$25 CAC

Test paid traffic with real orders at about $25 CAC; if acquisition costs rise, the model's Month 25 break-even gets harder fast.

2AOV Check$151 AOV

Confirm the first-year mix and 1.20 units per order really produce about $151 per order, because a smaller basket cuts room for rent and payroll.

3Margin Mix80.2% CM

In Year 1, procurement, freight, fulfillment, and payment fees total 19.8% of revenue, so you should see about 80.2% contribution before fixed costs.

4Fixed Load$19.4K/mo

The business carries about $19,405 of fixed cost each month, so avoid locking in the $3,200 showroom rent until orders clearly cover that base.

5Hire RampMonth 13

Delay the B2B sales hire until the facility pipeline is real, since the model starts that role in Month 13 and early payroll would just burn cash.

6Cash Cushion$749K

Hold enough cash for the Month 25 low point, because minimum cash hits about $749K and payback takes 38 months.
