Profit Margin

Hello,

Is there a way for the cost to display profit (gross) margin % instead? For example, right now the profit % is being calculated as price-cost/cost. But profit (gross) margin is calculated as price-cost/price.

For example, current method shows $2.25-$1.50 / $1.50 = 50%

Profit margin % as per my indication is calculated $2.25-$1.50 / $2.00 = 33%

Thanks!
