You are attempting to determine an approximation of what something costs to make or do. What makes the effort difficult is how complicated the effort becomes because of accounting rules and the assumptions that the models require.
At one point in my career, I thought you could get to a “real” cost of something. However, I learned repeatedly that the cost of something had much to do with decisions people made in the manufacturing or procurement process that guaranteed that the model was inaccurate. I now view costing as an art form, not a science. I view cost models as nothing but a theory on what something costs.
We still need cost models. With them, we get the opportunity to identify all of the costs that go into making something. Simple ones that focus on just the direct costs are the most accurate, as there are fewer assumptions. The allocation of indirect costs becomes overly complex and arbitrary, with decisions made based on logical constructs that may reflect reality, or may not. The more layers of allocated cost in the model, the more distorted the results become when you are attempting to see if the company will make any money on a product or not.
The stories here help illustrate how logical assumptions become arbitrary, or how they can distort the real costs of the business. There are articles on how to construct a product cost analysis or a freight cost analysis, with examples of how to do the work. Simple spreadsheets are for you to play with. You can also learn how to use a basic cost model spreadsheet and how to use it for pricing products based on the cost and not on the market price.

Sometimes I come on a bit too strong. I know I do. It is a nurture issue. I come from a family that is long on opinion, long on brains, and sometimes short on sensitivity. My problem is when I see something that is wrong, I gotta point it out. Read More
