Real Examples of Profit Margin Calculation
A boutique buys a jacket from its supplier for $40 and sells it to customers for $100.
This tells the store owner that 60 cents of every dollar is gross profit before rent, staff wages, and overhead.
A freelancer charges $1,200 for a website. Their direct costs (subscriptions & stock licenses) total $150.
Service businesses usually report higher margins because physical inventory costs do not eat into profit.
