Reading a Waste & Circular Economy result

A number on its own is the weakest thing a calculator can give you, so these tools pair each output with the comparison that gives it meaning: the gap to a target, the band the value falls in, or what a realistic swing in one input does to the answer. When a figure looks wrong, that is usually the fastest place to check — re-run it with one input moved and see whether the change lines up with the formula printed above the result.
