How do you calculate ingredient blend cost per kg?

Multiply batch weight by blended ingredient cost and by the yield percent, add the fixed setup and sanitation charge, then divide by batch weight. A 2,000 kg batch at $1.35/kg, 96% yield and $220 setup totals $2,812, or $1.406 per kg.

Why is the per-kg cost higher than the raw ingredient cost?

Two reasons: yield loss means you pay for material you do not ship, and the fixed setup and sanitation charge is spread over the batch. Here $1.35/kg raw becomes $1.406/kg loaded once both are folded in.

How does batch size affect blend cost?

The variable portion ($2,592 here) scales with weight, but the fixed $220 does not. On a small batch that $220 is spread thin over few kilograms, so per-kg cost climbs sharply; larger batches dilute the fixed charge.

What is a realistic yield after mixing losses?

Most dry blending operations retain 95-98% after transfer, dust collection and carryover flushing, so the 96% default is typical. Sticky fat-coated or high-molasses blends can run lower and deserve a measured figure.

Should sanitation cost really be in the blend cost?

Yes if the batch triggers a wet clean or allergen changeover, since that labor and downtime is a real cost of making that batch. If you run many identical batches between cleans, allocate the sanitation charge across all of them instead of loading it onto one.

How do I lower ingredient blend cost per kg?

Reformulate to cheaper equivalent ingredients, cut yield loss with better transfer and dust recovery, or run larger batches to dilute the fixed $220. The variable share here is 92% of the total, so material choice and yield move the number most.

Pet Food & Animal Nutrition Manufacturing calculator

Ingredient blend cost Calculator

Ingredient blend cost is the fully loaded cost of one mixer batch of a pet food or feed formula, combining the weighted raw-material cost, the shrink you lose to mixing and transfer, and the fixed setup and sanitation charge per batch. Formulators, cost accountants and plant managers use it to price recipes, compare formula alternatives, and defend margins when commodity prices for protein meals, grains and fats move. It matters because raw materials are the largest line in almost every pet food cost sheet, and a fraction of a cent per kilogram compounds fast across a production run. Splitting the total into variable and fixed dollars also shows how much of a small batch's cost is just changeover overhead.

What this calculator does

Estimate ingredient blend cost for a pet food batch from batch weight, weighted formula cost, process yield, and changeover setup.
A formulator costing a new diet uses this to price the blended ingredient cost per kilogram including sanitation changeover.
It computes the total and per-kilogram cost of a mixer batch by scaling batch weight and blended ingredient cost for yield loss, then adding the fixed setup and sanitation charge.

Formula used

Total = batch kg x ingredient cost x yield after losses% + setup & sanitation
Per kg = Total / batch weight

Inputs explained

Batch weight into the mixer:
Blended raw-material cost:
Yield retained after mixing losses:
Mixer setup & sanitation charge:

How to use the result

Use it when pricing a new formula, comparing ingredient substitutions, or deciding a minimum economical batch size given fixed changeover cost.
It uses a single blended ingredient cost, so it will not reveal which individual ingredient is driving the number; the yield term is a flat average and does not model give-away or carryover between products.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
The U.S. has 31,130 food manufacturing establishments employing about 1,707,316 workers (Census County Business Patterns, 2023).
