About Profit Margin

Gross Profit is the amount of sales dollars remaining after the cost of goods sold has been deducted. Gross profit margin is calculated with the following formula:

Gross Profit Margin = (Sales - COGS) ÷ Sales

If your gross profit margin is declining over time it may indicate that your inventory management needs to be improved or that your selling prices are not rising as fast  as the costs of the goods sold.

If you are a manufacturer it may mean that your production costs are rising faster than your prices and adjustments on either side (or both) are necessary.
