How do you calculate dye batch cost?

Multiply fabric weight by the combined dyestuff-and-chemical rate, apply the right-first-time yield factor, then add the fixed setup charge. With 450 kg at $6.80/kg, a 92% yield and a $260 setup, the batch costs $3,075.20.

What is dye batch cost per kg?

It is total batch cost divided by fabric weight. In the worked example, $3,075.20 over 450 kg gives $6.83 per kg dyed, which is the figure most merchandisers plug into a fabric price.

Why does right-first-time yield matter so much?

A shade that misses tolerance must be re-shaded or stripped and redyed, doubling chemistry and machine time. Dropping right-first-time from 92% to 80% on this batch would push chemical cost up meaningfully before you count the wasted machine slot.

What is a good dye batch cost per kg?

There is no universal figure, it depends on shade depth and substrate, but pales run far cheaper than deep navy or black. Use your own $6.83/kg baseline and watch how it moves as depth and auxiliary load change.

How can I lower dye batch cost?

Raise right-first-time yield with better lab-to-bulk correlation, load machines nearer capacity to spread the $260 setup, and rationalize the auxiliary recipe. The setup charge alone is $260 of the $3,075.20 total here.

Does this include effluent and water cost?

Only if you fold them into the dye-and-chemical rate or the setup charge. The calculator does not break them out, so add them explicitly when comparing low-liquor-ratio machines against conventional jets.

Dye Batch Cost Calculator

Dye batch cost tells a dyehouse what a single package, jet, or beam load actually costs to color, blending variable chemistry with the fixed cost of loading and heating a machine. Dye masters, costing engineers, and merchandisers use it to quote fabric prices and to decide whether small lots are worth running. Because dye and auxiliary chemistry can be 40-60% of finishing cost, and because a shade that fails right-first-time must be stripped and redyed, the yield factor here is where profit is won or lost. Running the number before a lot enters the dyehouse prevents underquoting on repeat greys and difficult navy or black shades.

What this calculator does

Estimates the all-in cost of a single dye lot including dyestuff, chemicals, yield, and machine setup.
Use it to cost a dye lot and see how shade-match yield and batch setup drive the per-kilogram dyeing cost.
It computes the total cost to dye one fabric batch and the resulting cost per kilogram, combining dyestuff-and-chemical spend adjusted for right-first-time yield plus a fixed machine setup charge.

Formula used

Batch cost = fabric weight x dye-and-chemical rate x first-time yield + setup charge
Cost per kg = batch cost / fabric weight

Inputs explained

Fabric weight per dye batch:
Dyestuff and auxiliary chemical rate:
Right-first-time dye yield:
Machine loading and utility setup charge:

How to use the result

Use it when quoting a dyeing order, comparing package vs jet routes, or deciding a minimum viable lot size for a given shade.
It treats the yield percentage as a simple multiplier on chemical cost and does not separately model the labor, effluent, or energy cost of a failed batch that must be stripped and redyed.
