Frequently Asked Questions
What is a profit margin and how is it calculated?
Profit margin is net profit divided by revenue, expressed as a percentage. A 20% net margin means you keep $0.20 of every $1.00 in revenue after all costs.
What is the difference between markup and margin?
Margin is profit divided by the selling price. Markup is profit divided by the cost. A 50% markup on a $10 item gives a $15 selling price but only a 33% margin.
How do I calculate my break-even point?
Divide your total fixed costs by the contribution margin per unit (selling price minus variable cost per unit). The result is the number of units you must sell to cover all costs.
Why do gross, operating, and net margins differ?
Gross margin only deducts cost of goods sold. Operating margin also deducts operating expenses like rent and salaries. Net margin deducts everything including interest and taxes.
