How do we round percentages and when do we use percentage points?


Best Answer

We trim the trailing zeros in percentages, otherwise we use two decimal places. We round when the measure is reported as being a “percent” type and the (value * 100) is greater than 0.5.


If you're discussing (i) change, or (ii) percent of whole for a measure whose type is "percent", we should see percentage point language. Ex. "three percentage points". The other scenario that this will appear is when we compare top entities. If you're discussing (i) comparison between two or more (change/difference/range), or (ii) percent of whole for a measure whose type is "percent", we discuss as percentage points.
