I only set that up as a 20% profit. That's why I was asking for suggestions and recommendations. I'm not apposed to increasing the profit margin. Or even have different margins for different parts.
First time doing this for electronics, so not entirely sure what margins should be for each thing.
And actually, as you pointed out, the resistors wouldn't actually be 13 cents.
$ 0.114 * 20% = 0.0228. So, it's 2.28 cents profit at 20%. The Markup column is total cost after margin.
