Question 1

What is profit margin?

Accepted Answer

Profit margin is the percentage of your selling price that remains as profit after subtracting your cost and any additional costs. It is commonly calculated as (Profit ÷ Selling Price) × 100, where Profit = Selling Price − Cost − Additional Costs.

Question 2

How do I interpret the percentage result?

Accepted Answer

The profit margin percentage shows how much profit you earn per dollar of revenue. For example, a 25% margin means you keep $0.25 as profit for every $1.00 in sales after costs included in the calculation.

Question 3

Why does profit margin differ from markup?

Accepted Answer

Profit margin is based on selling price, while markup is based on cost. Because they use different denominators, the same product can have a 50% markup but only a 33.3% profit margin.

Question 4

Should additional costs always be included?

Accepted Answer

Include additional costs when they are directly tied to the sale or necessary to deliver the product or service, such as payment processing fees, shipping, packaging, or platform commissions. If you are doing a quick pricing check, you can leave them out, but your margin may look higher than what you actually earn.

Question 5

Can profit margin be negative?

Accepted Answer

Yes. If your total costs (cost plus additional costs) are higher than your selling price, your profit becomes negative and the profit margin percentage will also be negative, indicating a loss on each sale.
