Forge cost vs market price
The forge cost below prices every input at today's market average. A positive margin means the finished chestplate sells for more than its inputs cost; a negative one means buying it outright is cheaper than forging it from bought materials. Daily sales tell you whether anyone is actually buying.
| Chestplate | Forge level | Materials | Forge cost | Market price | Margin | Sold/day |
|---|---|---|---|---|---|---|
| Tin Chestplate | 1 | 10 Tin Bar, 5 Coal Ore | 100 | 23 | -77 | 47 |
| Copper Chestplate | 5 | 10 Copper Bar, 5 Coal Ore | 180 | 39 | -141 | 14 |
| Iron Chestplate | 10 | 10 Iron Bar, 5 Coal Ore | 340 | 49 | -291 | 23 |
| Lead Chestplate | 15 | 10 Lead Bar, 5 Coal Ore | 250 | 49 | -201 | 59 |
| Steel Chestplate | 25 | 10 Steel Bar, 5 Coal Ore | 290 | 150 | -140 | 72 |
| Mercury Chestplate | 35 | 10 Mercury Bar, 5 Coal Ore | 330 | 60 | -270 | 31 |
| Chromite Chestplate | 50 | 10 Chromite Bar, 5 Coal Ore | 390 | 75 | -315 | 6 |
| Uranium Chestplate | 65 | 10 Uranium Bar, 5 Coal Ore | 460 | 249 | -211 | 2 |
| Mystic Chestplate | 70 | 10 Mystic Bar, 5 Coal Ore | 710 | 233 | -477 | 2 |
9 of 9 chestplates cost less on the market than their materials do. If you only want to wear the piece, buy it. Forging them still makes sense for Forge XP, or when the bars or logs came out of your own gathering.
