A first-year catfish farm needs about $72,700/month in break-even revenue to cover fixed and variable expenses before profit starts Here’s the quick math: fixed costs are $56,783/month, variable expenses are $4,895/month on $22,325/month of modeled sales, so contribution margin is about 781% At the modeled first-year sales level, the farm runs about $38,800/month below operating break-even Actual results vary by farm size, harvest timing, mortality, product mix, and sales channel

Which catfish farm expenses are fixed, and which move with sales?
Cost classification
Break-even only works if feed, juveniles, and selling costs move with volume while facility costs stay fixed. Misclassifying feed as overhead can make Month 17 break-even look safer than it is.
Expense
Cost
Break-Even Treatment
Common Mistake
Fish Feed
Variable
Model as 10.0% of revenue in the first year, declining with the forecast.
Treating feed like overhead instead of a volume-driven expense.
Processing Supplies
Variable
Model as 2.5% of revenue in the first year, tied to processed product volume.
Holding supplies flat while fillet and steak sales grow.
Packaging Materials
Variable
Model as 3.0% of revenue in the first year, tied to shipped and packed sales.
Forgetting packaging rises with every finished order.
Sales & Marketing
Variable
Model as 4.0% of revenue in the first year, then reduce per the forecast.
Budgeting it as a flat monthly spend during growth.
Purchased Juveniles
Variable
Use 10,000 juveniles at $0.65 each in the first year production cycle.
Missing the cash need before harvest revenue arrives.
Facility Maintenance
Fixed
Carry $5,000 per month from Month 1 through the planning period.
Reducing maintenance when sales are slow.
Insurance
Fixed
Carry $3,500 per month as a stable operating expense.
Linking insurance to fish volume instead of coverage needs.
General Utilities
Semi-variable
Start with the $1,000 monthly base; separate production power if usage tracks volume.
Putting all utilities in fixed overhead and hiding usage swings.
How does break-even change from a lean setup to a full catfish farming operation?
Scenario table
Scale lifts revenue and contribution, but fixed payroll and facility costs still stay ahead of sales in all three cases. The full model gets closest to break-even, yet it still runs a loss.
Planning assumptions only; small shifts in survival, feed, labor, or demand can move break-even.

What pushes catfish farming past break-even?
Stress test
The plan is fragile in the first year because $22,325 of revenue sits far below the $72,727 break-even level. Lower selling price, weaker harvest volume, higher feed and power use, and hiring ahead of sales can all widen the loss fast.

What should you verify before you commit to building a catfish farm?
Founder checklist
Before you buy tanks, hire the full team, or stock fish, prove the farm can sell about $72.7K a month and still survive the opening cash dip. The model does not reach breakeven until Month 17, and cash bottoms near Month 16 at about -$2.27M.
1Buyer demand$72.7K/mo
Verify signed buyers or repeat orders can reach this sales run rate before major spend, because that is the line between growth and a cash drain.
2Operating load$56.8K/mo
Your fixed overhead is about $56.8K a month, and the core build list adds $2.05M, so do not commit until the sales plan can carry both.
3Margin base80.5% CM
After feed, processing supplies, packaging, and sales spend, each revenue dollar keeps about 80.5 cents, so the mix has to hold.
4Harvest cadence1 cycle/yr
Keep the first year tied to one production cycle and match processing labor and cold storage to the harvest, not the wish list.
5Cash cushion-$2.27M
The model's cash low lands in Month 16, so fund the build and working cash before you count on Month 17 breakeven.
6Launch pricing$7/$14/$12/$10
Price Year 1 whole dressed, fresh fillets, frozen fillets, and steaks at those levels and confirm buyers want the mix, or volume will not convert into cash.
