Hi

Just got into building items. Looking for ways to boost profits and eleminate some cost. Is there anywhere that gives the data or how to make a sheet where I imput my amounts needed of minnerals and it takes refine rate skills standings ect? I would prefer to have a sheet for this but anything would be great. I just need to get raw numbers. Thanks

What you get will depend on your skills, the station or POS you are using, implants and taxes. Easiest solution is to drop 100 units of your favorite ore into the hopper and eve will tell you exactly what you'll get - you can cancel at that stage if you want.

yeah looking for something similar aswell, like a tool or webpage that will say which amount ( approx ) of ores to mine

ex like 10mil pyro, 5 mil plag etc

You can make it yourself in excel (you'll need to use the solver add-in) or any other spreadsheet program that has a solver feature. This is an example of how to do it, the trick is you want to set up the minerals that you need as constraints, and solve for volume (or cost), which seemed counter intuitive to me, when I was learning them.

The only website calculator I've seen is great, but presumes you have perfect refining skills (which I'd highly advise), and only uses the 5 high sec ores. It's designed to work with compressed ore 1 unit =100 uncompressed ore, so multiply units by 100.

If you could find a generic linear programming calculator, in something like Wolfram Alpha, you may be able to set up your own scenarios, though I would think it might take more time than it's worth because of the large number of relationships (ores to minerals, ores to size, etc) you would need to feed the solver, if it can't save them.

Well, https://www.fuzzwork.co.uk/compression/ is designed to work out the smallest volume of ore to get a specific quantity of minerals, and lets you pick your refining skill levels and so on. It works with compressed ore though.


As a note, there's a linear programming plugin for Google sheets, which I keep meaning to put an example together for.

This is, basically, the diet problem with different labels.

Woo! CSM XI!

Look for Dedaf's industrial spreadsheet.

Believe me when I say just stick to the Minerals unless you need so much that you can move them all in 1 go.

Fixed this up a few weeks ago to answer that very question. With the help of Steve ^^^ and other friendly people in the help channel.

If there was any profit to be made buying compressed ore, refining it and selling it again it wouldn't be there for long.

^^^ That is assuming the refining rate is what is set to the top left then the amount you make is scraps in the grand scheme of things.
