How do you calculate fiber usage cost for nonwovens?

Multiply fiber consumed by delivered price and by web yield, then add the blending and lay-down charge. With 2500 kg at $2.40/kg, 94% yield, and a $180 charge, the total is $5,820.

What is the per-kg fiber burden?

It is total fiber cost divided by fiber consumed, spreading both variable and fixed costs across every kilogram. In the example, $5,820 over 2500 kg gives a burden of $2.328 per kg.

How does web yield affect fiber cost?

Yield scales the variable portion of the cost in this model. The variable fiber cost of $5,640 plus the $180 fixed adder produces the $5,820 total, so changes in yield move the variable component directly.

What does the blending and lay-down charge cover?

It is the fixed processing cost to open, blend, and lay down the fiber for a run, independent of how many kilograms you consume. Here it adds a flat $180 on top of the variable fiber spend.

Why separate variable and fixed fiber cost?

Separating the $5,640 variable spend from the $180 fixed adder shows how cost behaves as volume changes. The fixed charge spreads thinner on larger runs, lowering the per-kg burden as quantity rises.

How can I lower fiber usage cost per kg?

Negotiate delivered price, improve web yield so less fiber is wasted, and amortize the blending charge over larger runs. Each lever pushes the $2.328 per-kg burden down.

Nonwoven Materials & Technical Textiles calculator

Fiber Usage Cost Calculator

Fiber usage cost captures the true material cost of a nonwoven run by combining fiber consumed, delivered fiber price, web yield, and a fixed blending and lay-down charge. Cost estimators, purchasing teams, and converting managers use it to quote rolls, validate margins, and compare fiber blends across carded, airlaid, and spunlaid products. Because fiber is typically the single largest variable cost in a nonwoven, and yield losses silently inflate the effective price per kilogram, getting this number right is central to competitive pricing. It separates the variable fiber spend from the fixed processing adder so you can see exactly where the cost lives.

What this calculator does

Estimate the delivered fiber cost embedded in a nonwoven run from charged weight, price and web yield.
A roll-goods estimator pricing a spunlaid or carded line uses it to size the fiber portion of a quote before locking margin.
It calculates total fiber usage cost as fiber consumed times delivered price times web yield, plus a fixed blending charge, and derives the per-kilogram fiber burden.

Formula used

Fiber cost = fiber consumed x delivered price x web yield% + blending charge
Per-kg fiber burden = total fiber cost / fiber consumed

Inputs explained

Fiber consumed:
Delivered fiber price:
Web yield:
Blending and lay-down charge:

How to use the result

Use it when quoting a nonwoven order, comparing fiber suppliers or blends, or analyzing how a yield change moves material cost.
It applies web yield as a direct multiplier on cost as configured; confirm that matches your costing convention, since some shops instead inflate consumed fiber by the inverse of yield to account for waste.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
