Profit margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. A product costing $80 and selling for $120 has a 33.3% profit margin but a 50% markup.
It varies widely by industry. Grocery retail: 1–3%. SaaS software: 60–80%. Consulting: 20–40%. Manufacturing: 5–20%. Compare your margin against your industry benchmark.
Gross profit margin excludes operating costs, taxes and interest — it is revenue minus cost of goods sold. Net profit margin deducts all expenses. This calculator computes gross profit margin.
Either increase your selling price, reduce your costs, or both. Even a 5% reduction in costs can have a significant impact on your margin. Regularly review supplier costs and overheads.
