Enterprise Ranking & Return per Scarce Resource

It ranks your chosen crop and livestock enterprises not just by gross margin per acre, but by return per the resource that actually limits your farm — land, labour hours, working capital or irrigation water. You pick a denominator and the whole basket re-sorts live, so the enterprise that earns the most per scarce unit rises to the top. It also names the binding constraint and flags when the per-acre winner is not the per-resource winner.

Gross margin is gross revenue minus total variable (operating) cost — the money an enterprise contributes toward fixed costs and profit before machinery depreciation, land and overheads. It is the standard first-pass measure in farm management because variable costs are the ones that change with the enterprise mix, making gross margin the right number to compare and to rank by per limiting resource.

Because the resource that constrains your farm — not land — sets your real ceiling on profit. If labour is the bottleneck during planting, the enterprise that earns the most per labour hour expands your whole-farm income, even if another crop earns more per acre. Ranking per acre quietly assumes land is the only limit; ranking per the binding resource allocates the thing you actually run short of.

Return per resource = gross margin per acre ÷ the resource used per acre under the chosen denominator. Per acre, the denominator is one, so it equals the gross margin. Per labour hour it divides by labour hours per acre; per dollar of capital it divides by peak working capital; per acre-inch it divides by irrigation water. The basket is then sorted high to low on that ratio.

The binding constraint is the resource you run out of first — the one that stops you growing more of your best enterprise. On a dry-land farm with cheap land it might be capital or labour; on an irrigated farm in a water-scarce basin it is usually water. Identify it honestly, set it as the denominator, and the ranking tells you which enterprise to favour to squeeze the most income out of that limit.

Because enterprises use resources in very different proportions. A high-value vegetable might win per acre yet be labour- and capital-hungry, so it falls down the ranking per labour hour or per dollar. A modest field crop that sips water can leap to the top per acre-inch in a water-limited setting. The re-rank is the insight: it reveals which enterprise fits your actual constraint.

The default per-acre revenue, variable cost, labour hours, working capital and irrigation water are representative figures synthesised from Texas A&M AgriLife Extension and Iowa State University Extension (Ag Decision Maker) enterprise budgets. They are typical, not a single year's quote — treat them as a starting point and adjust toward your own prices, yields and resource use.

No — it complements one. A linear-programming whole-farm optimizer solves for the single best mix given all constraints at once. This tool does something simpler and more intuitive: it re-ranks every enterprise by return per the one resource you believe is binding, so you can see the ordering and reasoning before committing to a full optimisation. It is the diagnostic step.

If an enterprise uses zero of the denominator — for example a dry-land crop that uses no irrigation water — its return per that resource is effectively unbounded, since it earns a margin while consuming none of the scarce input. The tool flags that as an infinite return and ranks it at the top, which is correct: under a binding water constraint, an enterprise that needs no water is the ultimate winner.

Yes. The basket includes a per-acre stocker-cattle enterprise alongside the crops, expressed on the same per-acre and per-resource basis, so grazing land competes directly with cropping for your land, labour, capital and water. That cross-enterprise comparison is exactly where ranking per scarce resource earns its keep — it puts very different enterprises on one honest scale.

Rarely. Ranking points you toward favouring the top enterprise up to its agronomic, rotational and market limits, not to monocropping. Rotation breaks pest cycles, markets cap how much you can sell, and risk argues for diversification. Use the ranking to tilt your area allocation toward the per-resource winners while respecting those real-world ceilings.
