Which crab pot supply expenses stay fixed, and which move with sales volume?

Cost classification

Break-even only works when unit-linked costs are separated from monthly commitments. In the first operating year, inventory sourcing is 12.0% of revenue and shipping is 7.0%, while rent, platform, insurance, and payroll set the monthly hurdle.

Expense	Cost	Break-Even Treatment	Common Mistake
Inventory Sourcing Costs	Variable	Treat as 12.0% of revenue in the first operating year; it reduces contribution margin on each sale.	Treating stock buys as immediate profit hits instead of margin and working capital.
Order Fulfillment and Shipping	Variable	Treat as 7.0% of revenue in the first operating year; each order carries packing and freight burden.	Ignoring outbound freight on bulky crab pots.
Retail and Warehouse Rent	Fixed	Include $4,500/month from Month 1 through Month 60 in the monthly break-even floor.	Scaling space before inventory turns prove out.
E-commerce Platform and Hosting	Fixed	Include $350/month from Month 1 through Month 60; sales volume does not lower the bill.	Expecting higher sales volume to reduce the monthly platform bill.
Utilities and Marine Security	Semi-variable	Start with the $650/month baseline and watch for higher handling, storage, or security usage as volume rises.	Missing the added operating load from heavier warehouse traffic.
Digital Marketing and SEO	Semi-fixed	Model the $1,200/month budget as a planned spend step, not a per-order charge.	Cutting spend before seasonal demand is measured.
Business Insurance	Fixed	Include $250/month across the planning range as required operating coverage.	Omitting recurring coverage from break-even overhead.
Payroll	Semi-fixed	Use staffing steps; the first-year staffed run-rate is about $15.1k/month from listed salaries and FTE levels.	Hiring ahead of order volume that covers contribution.

How does break-even shift across lean, base, and full sales cases for a commercial crab pot supplier?

Scenario table

The break-even point shifts because fixed overhead stays near $220k a month, so only sales volume changes how much of that cost contribution can cover. Lean stays short, base lands at break-even, and full creates cushion.

Planning assumptions only, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$71k	$14k	$220k	80.3%	-$163k	A $163k monthly gap keeps break-even risk high.
Base break-even case	$272k	$52k	$220k	80.9%	$0	Month 26 is the break-even point, so coverage is just enough.
Full season case	$476k	$81k	$220k	83.0%	$175k	Profit turns positive, so the model has cushion above break-even.

What pushes this crab pot supplier past break-even?

Stress test

This plan is fragile: a 10% sales miss, higher freight, or extra storage labor can turn a $272k break-even into a gap. The biggest swing factor is margin, because a move from 19% to 22% variable costs pushes break-even to $282k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$272k	$0 cushion	Break-even has no buffer.
Revenue shortfall	Sales fall 10% from break-even revenue.	$272k	$22k gap	A small demand miss opens a cash hole.
Fixed-cost pressure	Fixed overhead rises 10% to $242k.	$299k	$27k gap	Storage or labor creep lifts the bar fast.
Margin pressure	Variable expenses rise from 19% to 22% of sales.	$282k	$10k gap	Higher freight and packaging cut contribution.
Combined pressure	Fixed overhead rises 10% and variable expenses rise to 22% of sales.	$311k	$39k gap	Cost pressure plus softer demand can break the plan.

Can you prove this crab pot supply business can clear break-even before you lock the lease and hire?

Founder checklist

Don't commit to the warehouse, staff, or launch spend until the model can carry its monthly fixed load and opening cash need. Treat Month 26 break-even and Month 45 payback as planning gates, not promises.

1Traffic proof45-120/day

Verify that weekday traffic can move from 45 Monday visitors to 120 Saturday visitors and still convert at 4.5% in Year 1, because break-even needs real buyers, not just visits.

2Fixed load$6.95K/mo

Verify rent, hosting, utilities, marketing, and insurance stay near $6.95K a month, because that fixed burn sits under every sales forecast.

3Margin floor81% CM

Check that the 12% sourcing cost plus 7% shipping still leaves about 81% contribution margin before payroll, or the break-even math gets much tighter.

4Payroll ramp$181K/yr

Hold the extra hire until contribution can cover the Year 1 payroll run-rate of about $181K, because the e-commerce role steps up from 0.5 FTE in Month 6.

5Cash cushion$311K

Keep at least $311K in reserve through Month 25, since that is the model's low point and you do not hit break-even until Month 26.

6Launch setupMonth 3-4

Validate supplier lead times and order minimums, then set receiving, pallet handling, pickup, and damage checks before the vehicle arrives in Month 3 to Month 4, so bulky pots don't clog space or cash.
