# Calculator:Disassembly by material

 This calculator or section is incomplete and could do with improvement.Reason: Needs much more research to have all items - please contribute here!You can discuss this issue on the talk page or edit this page to improve it.

The following subpages are cost-analysis tables of items that give each specific material.

Items that give a specific material need several points of information to calculate the cost for that material:

• The Grand Exchange price of the item - known (though be wary of inaccurate prices)
• The junk chance of the item - known (via Analyse)
• The number of materials the item gives upon disassembly - known (via Analyse)
• The chance of getting the specific material, after junk - estimated by gathering data. Please contribute to the research here!

The formula used to calculate the average cost per specific material is ${\displaystyle {\frac {\text{price of item}}{\text{average number of specific material}}}}$ where the average number of specific material can be calculated by ${\displaystyle {\text{number of materials}}\times (1-{\text{junk chance}})\times ({\text{specific material chance}})}$

Several of the above have been pre-filtered by buy limit as they contain a large number of items with low buy limits, making them a poor option for bulk disassembly. They usually end up with multiple pages due to processing limits. See the full versions here:
