How the floor is calculated
BX2-ZX X - Moon 12 · BX2-ZX · F-RA63
The floor is what the alliance would earn by dropping a Metenox on this moon — the passive income active miners have to beat. The chain:
monthly ore units → split by composition → reprocess (× refine yield) → value materials at Jita split → gross − Magmatic Gas fuel = floor
Value at each Jita price
| Basis | Mined value / mo | − fuel | Net / mo | Per 3-mo term |
|---|---|---|---|---|
| Jita buy | 729.5M | −52.4M | 677.2M | 2.03B |
| Jita split (floor basis) | 744.5M | −52.4M | 692.2M | 2.08B |
| Jita sell | 759.5M | −52.4M | 707.1M | 2.12B |
Jita sell is the optimistic ceiling (you fill your own sell orders); Jita buy the floor (dump everything to buy orders); split the midpoint the auction floor uses.
Inputs · from settings
| Base moon extraction | 30,000 | m³ / hour (game constant) |
| Metenox efficiency | 40% | of a manually worked Athanor/Tatara |
| Hours / month | 730 | 730 = 365 × 24 ÷ 12 |
| Moon ore volume | 10 | m³ / unit |
| Refine yield (max skills + structure) | 90.6% | of the theoretical 100% reprocessing result |
| Magmatic Gas burn | 40 | units / hour → 29,200 / 30 days |
| Material prices | Jita split | buy/sell midpoint if "split" |
| Magmatic Gas price | 2k | Jita sell, per unit |
Step 0 — how much a Metenox pulls in 30 days
30,000 m³/hr × 40% × 730 hr
= 8,760,000 m³ of moon ore
÷ 10 m³/unit = 876,000 units of moon ore / 30 days
Step 1 — split the monthly ore by composition
| Ore | Share | Units / 30 days | = portions (÷100) |
|---|---|---|---|
| Sylvite | 61.3% | 536,988 | 5,370 |
| Cobaltite | 26.7% | 233,517 | 2,335 |
| Chromite | 12.0% | 105,495 | 1,055 |
Step 2 & 3 — reprocess each ore, then value the materials
per material: portions × SDE yield × 90.6% × Jita split price
Sylvite — 476.0M / 30 days
| Material | Units / 30 days | Jita split | ISK / 30 days |
|---|---|---|---|
| Pyerite | 19,460,445 | 16 | 316.7M |
| Mexallon | 1,946,045 | 49 | 94.6M |
| Evaporite Deposits | 316,232 | 204 | 64.6M |
Cobaltite — 51.1M / 30 days
| Material | Units / 30 days | Jita split | ISK / 30 days |
|---|---|---|---|
| Cobalt | 84,626 | 604 | 51.1M |
Chromite — 217.4M / 30 days
| Material | Units / 30 days | Jita split | ISK / 30 days |
|---|---|---|---|
| Hydrocarbons | 9,558 | 443 | 4.2M |
| Chromium | 38,232 | 6k | 213.2M |
Step 4 — gross
| Refined material (all ores) | Units / 30 days | ISK / 30 days |
|---|---|---|
| Pyerite | 19,460,445 | 316.7M |
| Chromium | 38,232 | 213.2M |
| Mexallon | 1,946,045 | 94.6M |
| Evaporite Deposits | 316,232 | 64.6M |
| Cobalt | 84,626 | 51.1M |
| Hydrocarbons | 9,558 | 4.2M |
| Gross | 744,509,879 ISK | |
Step 5 — Magmatic Gas fuel
40 / hr × 730 hr = 29,200 units × 2k = 52,355,600 ISK / 30 days
Step 6 — floor
| Gross | 744,509,879 ISK |
| − Magmatic Gas fuel | −52,355,600 ISK |
| Model floor | 692,154,279 ISK / 30 days |
| Floor used by the auction | 692,154,279 ISK / month |
Step 7 — what a bidder pays
| Term length | 3 months |
| Minimum monthly bid | 692,154,279 ISK (the floor) |
| Prepaid to the alliance on winning | bid × 3 — at the floor, 2,076,462,837 ISK |
| Viability floor | 300,000,000 ISK / month — clears it |
