Work through the numbersKnow what the numbers mean
A useful estimate starts with clear assumptions.
01
Start with the example
Each tool opens with an illustrative scenario so you can see the logic before changing the inputs.
02
Use your own costs
Enter your actual stock or operating assumptions. Avoid counting the same cost or reservation twice.
03
Check the boundaries
Read the exclusions and confirm vendor quotes. The tools support a decision; they do not predict an outcome.
