When should I use margin vs markup?
Use margin when analyzing financial statements or comparing profitability across companies — it is the standard in accounting and investor reporting. Use markup when setting prices from cost — it is more intuitive for pricing decisions. Retail buyers typically think in markup; CFOs and analysts think in margin.
What is a healthy profit margin?
It depends entirely on industry. A 5% net margin is excellent for grocery (Walmart averages 2.4%). Below 20% would be concerning for SaaS (industry average is 25–30%). A 10% net margin is generally considered healthy across most industries. Compare against direct competitors, not cross-industry averages.
How does volume affect margin?
Higher volume typically improves margins through economies of scale — fixed costs (rent, equipment) are spread across more units. A bakery selling 100 loaves at $5 with $200 fixed costs has a $3 margin per loaf. At 500 loaves, fixed cost per loaf drops from $2 to $0.40, increasing margin to $4.60 per loaf.
