Frequently asked questions
Quick answers before you start.
What is the difference between margin and markup?
Margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. A 33% margin means you keep one-third of every sale; a 50% markup means you added half the cost on top.
What is a good profit margin?
A 20–40% net margin is healthy for most small businesses across sectors. Services can push higher since there's little cost of goods. If your margin is under 10%, pricing or costs need attention.
How do I increase my profit margin?
Raise prices (the fastest lever), cut costs, or shift to higher-margin offerings. Raising prices 10% on a 25% margin business improves margin by roughly 8 points, so it usually beats cost-cutting.
