Can you show a worked example?
With Vacant units = 3 and Total units = 40, the calculator returns Vacancy rate = 7.5%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.
What does it give for smaller values?

What else is worth having open alongside it?
