Which fish farm expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if overhead is kept separate from production-linked spending. For this fish farm, feed, juveniles, mortality exposure, and stocking losses belong in production risk, not fixed overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease & Maintenance	Fixed	Use $15,000/month as base overhead before contribution margin.	Spreading rent across fish volume and hiding capacity pressure.
Insurance	Fixed	Use $2,500/month as recurring operating overhead.	Dropping it from break-even because it is not tied to harvest volume.
Regulatory Compliance & Certifications	Fixed	Use $1,000/month as required overhead during the planning range.	Treating compliance as optional until sales scale.
Software Subscriptions	Fixed	Use $1,500/month as a stable systems expense.	Modeling software as a percentage of revenue without support for it.
Fish Feed	Variable	Model first-year feed at 8.0% of revenue, falling to 6.0% by the mature year.	Treating feed as overhead instead of a production-linked input.
Purchased Juveniles	Variable	Use $0.80 per juvenile in the first year, tied to stocked production cycles.	Ignoring mortality and stocking losses when estimating usable harvest output.
Energy for Water Circulation & Temperature Control	Semi-variable	Split the 5.0% revenue-linked energy load from the $3,000/month base utilities charge.	Putting all utilities into fixed overhead and missing usage spikes.
Facility Technicians	Semi-fixed	Step labor up as scale grows, from 3.0 FTE in the first year to 6.0 FTE by the mature year.	Assuming labor rises smoothly with revenue instead of in hiring steps.

How does break-even change from lean to full fish farming scale?

Scenario table

The gap narrows as scale rises, but fixed payroll and facility overhead still stay ahead of contribution in every case. That means survival, harvest weight, and sales mix have to improve together before the farm reaches break-even.

Planning assumptions only; actual results will move with survival, harvest weight, and sales mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean first-year fish farm case	$397K	$85K	$974K	78.5%	-$662K	Still far below break-even; overhead is too heavy.
Base Year 3 fish farm case	$911K	$170K	$1,274K	81.3%	-$533K	Closer, but fixed costs still outrun contribution.
Full Year 5 fish farm case	$1,744K	$283K	$1,487K	83.8%	-$26K	Nearly there, but a small gap still remains.

What breaks the fish farm break-even plan?

Stress test

Year 1 revenue is about $397K versus a $1.241M break-even level, so the model starts with an $844K gap. Feed, power, health, packaging, and mortality are the main pressure points because they raise break-even fast without trimming fixed costs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.241M	$844K gap	The model starts far below break-even.
Revenue shortfall	First-year revenue falls 10% below plan.	$1.241M	$884K gap	A small sales miss widens the hole fast.
Fixed-cost increase	Monthly fixed overhead rises 10%.	$1.365M	$968K gap	Lease, payroll, and admin costs do not flex.
Margin pressure	Feed and energy rise 20%, and mortality worsens to 13%.	$1.291M	$894K gap	Higher feed, power, and losses cut each sale's cover.
Combined pressure	Sales fall 10%, fixed overhead rises 10%, and feed and energy rise 20%.	$1.419M	$1.062M gap	Small misses stack up into a seven-figure gap.

What should you verify before signing for land, tanks, and fish stock?

Founder checklist

Don’t commit to land, tanks, or stock until the water, power, feed, and buyer path are proven. Year 1 fixed payroll is about $70.4K a month, nonpayroll fixed overhead is $27K, and the model still needs roughly $124K a month to break even, so timing and demand matter.

1Water pathPre-close

Verify water access, discharge rules, and the permit path before you commit to land or facility spend, because a blocked site can stop the whole farm before Month 1 cash burn starts.

2Backup power$250K

Verify the backup generators and run-time plan before you stock live fish, because the model includes $250K for generators and a power gap can turn healthy stock into a write-off.

3Feed terms81% CM

Lock feed supply and price terms before you assume the Year 1 8.0% feed line, because feed, energy, health, and packaging total 19% of revenue and leave an 81% contribution margin.

4Cycle capacity10,000/cycle

Confirm juvenile supply and tank and processing capacity before you commit to the first production cycle, because the plan assumes 10,000 purchased juveniles per cycle and output rises with 1.5 to 1.9 cycles a year.

5Sales proof$124K/mo

Test buyer demand for whole fish at $8/kg, fillets at $18/kg, smoked portions at $25/kg, and live juveniles at $0.75 each before you expand the mix, because Month 15 break-even depends on real orders, not hopes.

6Cash load-$7.9M

Match hiring to cycle timing; Year 1 payroll is about $70.4K a month plus $27K of other fixed overhead, and the model still dips to a $7.9M cash trough in Month 14 if sales lag, so delay discretionary spend until contracts support the $124K monthly break-even target.
