Frequently Asked Questions
Profit margin (gross margin) is profit divided by revenue: if you buy for $50 and sell for $100, your margin is 50%. Markup is profit divided by cost: the same numbers give a 100% markup. They measure the same profit from different bases. This is why they are NOT interchangeable — a 50% margin is NOT the same as a 50% markup. A 50% margin corresponds to a 100% markup, and a 50% markup corresponds to a 33.3% margin.
It depends heavily on the industry. Software and SaaS: 70–90% gross margin. Consulting and professional services: 60–80%. Retail (physical goods): 30–50%. Manufacturing: 25–45%. Restaurants: 60–70% gross (but net margins are only 3–9% after labor and overhead). A "good" margin is one that covers your operating expenses and generates enough net profit to sustain and grow the business.
Multiply the number by the percentage and divide by 100. For example, 15% of 200 = (15 ÷ 100) × 200 = 30. Use the "% of Number" tab and enter the percentage and base number.
Divide X by Y and multiply by 100. For example, 30 out of 200 = (30 ÷ 200) × 100 = 15%. Use the "X is what % of Y" tab.
