What does costed ingredient share mean?

The share of the batch, by mass, whose ingredients carry a cost in the blend. Water and cheap fillers often sit outside it, so the share is not the whole formula.

Why is the batch size in kilograms?

Formulation costs balance on mass, so kilograms are the basis. A formula written in liters converts through its density at the batch temperature before you enter it.

What is the fixed batch cost adder for?

Charges that do not scale with batch size, such as a lab fee, a certification or a minimum order premium. The calculator spreads it across the batch as a cost per kilogram.

How do I set the target cost per kilogram?

Use the standard cost or the quoted price. At the defaults the batch costs 6.125 per kilogram against a 6.25 target, a margin of 0.125.

Formulation Batch Cost Calculator

Cost a formulation batch by mass from its size, blended ingredient cost and costed share, then add the fixed batch adder. The result is judged against the target cost per kilogram you enter.

What this calculator does

Ingredient cost and cost per kilogram of a formulation batch, measured by mass, judged against a target cost.

Formula used

Ingredient cost = batch size × blended ingredient cost × costed share ÷ 100
Total batch cost = ingredient cost + fixed batch cost adder
Cost per kilogram = total batch cost ÷ batch size
Costed mass = batch size × costed share ÷ 100; fixed cost per kilogram = fixed adder ÷ batch size
Margin to target = target cost per kilogram − cost per kilogram

Inputs explained

Batch Size: Bulk kilograms charged to the compounding vessel.
Blended Ingredient Cost: Blended cost per kilogram of costed ingredients.
Costed Ingredient Share: Share of batch mass carrying an ingredient cost.
Fixed Batch Cost Adder: Batch costs that do not scale with size.
Target Cost per Kg: Cost per kilogram the quote or standard allows.

How to use the result

Best suited to costing a new or scaled formula, checking a reformulation against a cost target.
The fixed adder covers one batch; split it when a run shares the cost. Ingredient prices move, so refresh the blended cost before quoting.
