Wool Income vs Shearing Cost Calculator NZ
This puts what a clip earns against what it costs to get it off, and tells you what is left per head, per kilogram and across the flock. It also works out the wool price at which the whole exercise breaks even, which for strong wool is the number most worth knowing. The framing matters here more than the arithmetic. Shearing is an animal welfare requirement, not an optional harvest, so the question was never whether to shear: it has to happen whatever wool is worth. What the net figure actually measures is how much of a cost you were going to carry anyway the wool manages to offset, and treating a negative result as a loss on a product you chose to make gets the decision backwards. The costs to count are wider than the shearing rate. Crutching is separate and happens at a different time of year, and on top of the shearers there are shed hands, the presser, food on a bigger board, then cartage and selling costs at the far end. Counting only the shearing rate is how a clip that is losing money comes to look like it breaks even. No wool price is supplied here, because it moves constantly and by type.
Shearing is an animal welfare requirement rather than an optional harvest, so this measures how much of a cost you were carrying anyway the wool offsets.
At these costs and this fleece weight, the clip covers itself at $1.89 a kilogram of greasy wool. The price received is $0.61 a kilogram above that, so the clip is clearing its costs.
How it works
Income is the sheep count multiplied by the greasy fleece weight and the price a kilogram. Costs are shearing and crutching per head, multiplied out across the flock, plus the shed and selling costs entered as totals. The net is the difference, and the per head figure divides it back across the flock. The break even price is the total cost divided by the total greasy wool, which is the price a kilogram at which income exactly meets cost. Everything is greasy weight rather than clean, because greasy is what you weigh in the shed and what most people are quoted on.
What the break even price is good for
It converts every cost on the page into a single number in the same units as the market, so you can hold it against what wool is making this week without doing any further arithmetic. It also shows where the leverage is. Fleece weight sits underneath it as much as cost does: heavier fleeces spread the same per head shearing charge over more kilograms and pull the break even price down, which is why the same shearing rate is comfortable on one flock and marginal on another.
Worked example
A thousand sheep cutting 4.5 kilograms of greasy wool each produce 4,500 kilograms. At $2.50 a kilogram that is $11,250 of income. Shearing at $5.50 a head is $5,500, crutching at $1.80 is $1,800, and $1,200 of shed hands and food brings the costs to $8,500. That leaves $2,750, or $2.75 a head. The break even price is $1.89 a kilogram, so this clip is clearing its costs with room, but a fall to below $1.89 would put the wool underwater against a cost that still has to be paid.
