How to read them
Arithmetic, not advice.
Each tool shows the formula it uses and states the assumptions that change the answer. Nothing here encodes an industry benchmark or an improvement we claim a product delivers — every number comes from the figures you enter, and none of them leave your browser.
Want these numbers on your own data?
We'll work through your forecasts, schedules and shrinkage with you — and show where WFMPro would carry it from there.
