Kill Sheet Calculator NZ
This checks a kill sheet: what a consignment grossed, what came off it, what landed in the account and, most usefully, what price per kilogram you actually realised once the deductions are counted. That last figure is the one worth having, because the schedule price everyone quotes is applied to carcass weight before anything is taken off, and the deductions come afterwards. Levies, processing, inspection and cartage are usually charged per head, which means their effect per kilogram depends entirely on how heavy the carcass was: the same three dollars is worth far more against an 18 kilogram lamb than against a 30 kilogram one. So two consignments killed on the same schedule in the same week can realise quite different prices, and a contract premium can be more than swallowed by what comes off underneath it. Working every consignment back to a realised price per kilogram is the only way to compare them honestly, and it is the only way to tell whether a premium was actually worth taking. Nothing here carries a schedule price, a levy or a processing charge, because those change constantly and differ by processor, by grade and by contract. Every figure comes off the sheet in front of you.
Everything on this page comes off your own sheet. Schedule prices, levies and processing charges differ by processor, grade, contract and week, so none is supplied here.
The net payment works out at $8.35 a kilogram of carcass weight, against a quoted schedule of $8.50. That is $0.15 a kilogram below the schedule, because the per head deductions are worth $0.35 a kilogram against a carcass this size.
How it works
The price applied per kilogram is the schedule price plus any grade adjustment and any contract premium, and that is multiplied by carcass weight to give the gross value of a carcass. Deductions per head come off, credits go on, and the result is the net per head. Multiply by the head count and you have the consignment. The realised price is the net per head divided by the carcass weight, which converts everything, including the per head charges, back into dollars a kilogram so it can be set beside the schedule.
Why the per head charges matter more than they look
A deduction charged per head is a fixed cost against a variable weight. Six dollars and fifty cents against an 18.5 kilogram carcass is 35 cents a kilogram; against a 30 kilogram carcass it is 22 cents. That is the whole reason lighter stock realise less per kilogram than the schedule suggests, even before grading. It also means the arithmetic on whether to hold stock longer is not just about the extra weight and the schedule at the time, but about spreading the same fixed charges over more kilograms.
Worked example
Two hundred and fifty lambs averaging 18.5 kilograms carcass weight, on a schedule of $8.50 a kilogram with a 20 cent contract premium and no grade adjustment, gross $160.95 a head. Deductions of $6.50 a head bring that to $154.45 net, and the consignment to $38,612.50. The realised price is $8.35 a kilogram, which is 15 cents below the quoted schedule despite the 20 cent premium sitting on top of it, because the per head deductions are worth 35 cents a kilogram against a carcass this size.
