Frequently asked questions

What is the difference between margin and markup?

Both measure profit, but against different bases: margin divides profit by the sale price, markup divides it by the cost. Markup is always the larger percentage.

What margin should I aim for?

It varies widely by industry — retail often runs on tight margins while services can be much higher. Know your costs and your competitors.
