Illiquid. Serpentis Large Railgun Battery 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)7,128,377.81
fee = EIV × ( index 17.22% + facility 0.25% + SCC 4% )
= 7,128,377.81 × 21.47%
Install fee, whole job1,530,462.72

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.

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 17.22%. 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: 1.6 trades/day, 3 units/day.
