Frequently Asked Questions

A gross margin of 50% to 70%+ is standard for ecommerce and retail products to ensure sufficient buffer to cover digital marketing, shipping, and administrative overhead.

It subtracts the cost of goods sold from revenue to get gross profit, then divides gross profit by revenue as a percentage. On $80 of revenue with $30 of COGS, gross profit is $50 and the gross margin is 62.50%.

Gross profit is the dollar figure — revenue minus COGS. Gross margin is that profit expressed as a percentage of revenue, which lets you compare profitability across products or periods of different sizes.

Revenue must be greater than zero, or the calculator stops with 'Enter a valid revenue or retail price.' since it is the denominator of the margin. COGS is subtracted as entered.

Yes. If the cost of goods sold exceeds revenue, gross profit is negative and the gross margin percentage is negative, showing the product is sold below its direct cost.
