The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
COGS percentage formula
COGS percentage = cost of goods sold ÷ sales revenue × 100.

When gross profit is simply revenue less COGS, COGS % plus gross profit % should equal 100%.
