Illiquid. 250mm 'Flintlock' Railgun trades under 5 times a day; under 10 units traded a day. Any profit below is arithmetic on a book that barely moves — it is not a business you could run at size.

Job install fee

Estimated Item Value (EIV)2,054,836.21

fee = EIV × ( index 17.23% + facility 0.25% + SCC 4% )

= 2,054,836.21 × 21.48%

Install fee, whole job441,378.82

The fee is charged on the job’s Estimated Item Value — the blueprint’s ME0 quantities priced at CCP’s adjusted prices — not on what the materials cost you. A researched blueprint cuts your material bill and leaves this number completely unchanged. Where you install the job is the lever that moves it.

Sale in Jita

Jita buy price, per unit305,600

Net revenue, per unit3,759,630.75

Net revenue, whole job (1 unit)3,759,630.75

Fee profile: Omega trader. Sales tax always applies; the broker fee is charged because the realistic exit is a sell order at the ask, not dumping the run into buy orders.

EIV basis is CCP’s published adjusted price. It exists to compute the install fee and nothing else — nobody sells at it, so it is never used as a cost here.

Assumptions behind every number above

Material efficiency 10 and 1 run. ME is applied to the whole job and rounded once, never per run, and no material ever drops below one unit per run.
Installed in Jita, manufacturing cost index 17.23%. Facility tax 0.25%, SCC surcharge 4%.
Materials and the finished item are priced from the live Jita book (The Forge). The install fee is computed from CCP’s adjusted prices, which are an index, not a quote.
Sale assumes a sell order at the current Jita ask, paying 2.02% sales tax and 1.50% broker fee (Omega trader). No hauling, no time cost, no blueprint cost.
30-day Jita context: 2.5 trades/day, 5 units/day.
