Aquaculture Profitability

Gross Revenue is Total Production multiplied directly by Sale Price, and Total Costs don't depend on price at all, so every additional cent per pound flows straight through to Net Profit (revenue minus costs) with nothing offsetting it. This makes Sale Price one of the most direct levers in the calculator — a small per-pound price increase applied across a large harvest volume can meaningfully change your bottom line.

Feed Cost is added directly into Total Costs, which is subtracted from Gross Revenue to get Net Profit, so a higher feed bill subtracts more from the same revenue regardless of any other input. Because feed is typically the single largest cost category in aquaculture — commonly on the order of half or more of total production cost — small swings in feed price or feed conversion efficiency tend to have an outsized effect on profitability compared to the other cost categories.

With the default 10,000 lbs of production and $23,000 in combined feed, fingerling, and operating costs, the break-even price works out to $2.30 per pound — below that price, Net Profit is negative; above it, the operation turns a profit. This is exactly what the Break-Even Price output calculates for whatever numbers you enter: Total Costs divided by Total Production.

In this calculator, increasing Total Production while holding your cost and price inputs fixed always raises Net Profit, because more pounds sold at the same price generates proportionally more revenue against unchanged costs. In a real operation, though, producing more fish usually means spending more on feed and labor too — this calculator doesn't automatically scale Feed Cost or Operating Costs with Total Production, so you should update those inputs yourself to reflect a genuinely larger harvest rather than just raising the production number in isolation.

Profit Margin expresses Net Profit as a percentage of Gross Revenue — it answers "of every dollar I sold, how much was profit?" Return on Investment expresses the same Net Profit as a percentage of Total Costs instead — it answers "for every dollar I spent, how much profit did I get back?" Because Total Costs is smaller than Gross Revenue in a profitable operation, ROI is typically a higher percentage than Profit Margin for the same underlying numbers.
