How do you calculate metal price sensitivity for cathode material?

Multiply the metal-containing tonnage by the per-kg price change and by the exposed (un-hedged) share, then add fixed contract or freight impacts. With 100 kg, a $45/kg change, 80% exposed and $250 fixed, variable exposure is 100 x 45 x 0.80 = $3,600 and total exposure is $3,850.

What is the exposed purchase share?

It is the percentage of your metal volume that floats with the market — not locked under a fixed-price contract or covered by an LME hedge. At 80% exposed, only four-fifths of the tonnage moves with the price; the rest is protected, which is why it scales the variable term down.

Why separate fixed costs from variable metal exposure?

Freight surcharges, contract premiums and conversion fees move independently of the metal index. Keeping the $250 fixed impact separate from the $3,600 variable exposure lets you hedge only the market-driven part and avoids over-hedging.

What is effective price exposure per kg?

It is total exposure divided by tonnage — $3,850 / 100 kg = $38.50/kg here. It tells you the blended cost swing per kilogram once the un-hedged share and fixed adders are folded in, which is handy for re-pricing a quote.

Metal price sensitivity vs a full landed-cost model?

This tool answers 'how much does my cost change if the index moves $X?' A landed-cost model answers 'what does the material cost in total?' Use sensitivity for risk and hedge sizing, landed cost for absolute quoting.

How do I handle an NMC811 basket with three metals?

Run it once per payable metal — nickel, cobalt and manganese — using each metal's own contained mass and price change, then add the totals. Lithium is usually indexed separately and should be a fourth run.

Cathode Active Material & Precursor Manufacturing calculator

Metal Price Sensitivity Calculator

Metal price sensitivity tells a cathode active material (CAM) or precursor (pCAM) producer how much a move in nickel, cobalt, lithium carbonate or manganese sulfate pricing flows through to landed cost. Procurement leads, cost engineers and commercial teams at NMC, NCA and LFP plants run it to size LME and metal-index risk on a given tonnage and to decide what fraction of purchases needs hedging or pass-through clauses. Because metal accounts for the large majority of CAM cash cost, even a few-dollar-per-kg move on a multi-tonne order materially changes margin. This calculator isolates the variable, market-driven exposure from fixed contract and freight effects so you can quote and hedge against the right number.

What this calculator does

Estimate cost exposure from nickel, cobalt, manganese, lithium, or dopant price movement for a CAM or precursor production volume.
Use it when metal price sensitivity in cathode active material and precursor manufacturing is being put through a cathode active material and precursor manufacturing weighted-cost review.
It computes the dollar exposure of a metal-content purchase to a stated price change, scaled by the share of volume that is actually exposed (not hedged or fixed-price), then adds any fixed contract or freight cost impact.

Formula used

Variable metal price exposure = metal-containing material exposure × metal price change × exposed purchase share
Total metal price exposure = variable metal price exposure + fixed contract or freight cost impact

Inputs explained

Metal-containing material exposure:
Metal price change:
Exposed (un-hedged) purchase share:
Fixed contract or freight cost impact:

How to use the result

Use it when an LME or index move is announced, when negotiating a metal pass-through clause, or when sizing the hedge ratio for an upcoming precursor or CAM purchase order.
It models a single linear price move on one metal stream and ignores stoichiometric blending across Ni/Co/Mn, payable-metal percentages and timing lags between index settlement and invoicing, so multi-metal NMC baskets must be run per metal and summed.
