# Calculator:Disassembly by material/Ethereal

This is a list of all tradeable items that can give Ethereal components with the effective cost per Ethereal component.

Notes
• GE prices may be inaccurate - we can't really do anything about that
• Untradeable items are excluded, with some exceptions

In the table:

• The "materials each" column is not the number of X components the item gives, but rather how many total materials you'll get everytime you disassemble the item.
• The raw chance column is the chance per non-junk material to get Ethereal components when disassembling the item.
• The Avg. number column is the number of Ethereal components you should expect when disassembling each item; this represents the junk chance and the number of materials in addition to the raw chance (formula: ${\displaystyle {\text{number of materials}}\times (1-{\text{junk chance}})\times {\text{specific material chance}}}$). It is listed as a percentage, to reduce decimal places needed.
• For example, if an item has an average number of 0.13%, you should expect that you'll get 13 materials in 10,000 disassembles (0.13 per 100 disassembles, 0.0013 per disassemble) on average
• The cost per mat amount is ${\displaystyle {\frac {\text{price per disassemble}}{\text{avg. number}}}}$
• The materials per hour column is based upon performing the ideal 3,000 disassembly actions per hour. In reality, it will probably be less due to connection latency, server latency, and human error. The column also makes no attempt to account for buy limits or availability.
• The efficiency ratio column can be enabled by the checkbox below. Efficiency ratio is a measure of your efficiency when disassembling this time, taking into account the value of your time - see efficiency for details. The lower the number, the more efficient it is to disassemble. This, again, makes no attempt account for buy limits or availability, nor extra time spent obtaining untradeable items.
• The average number and cost is given for no junk reduction by default, but this can be changed with the following drop-down menu (requires JavaScript):
Please enable JavaScript to be able to change the junk reduction used, or switch to auto disassemblers. Until then, the table displays values for no junk reduction with no machine only.
