What's the formula for markup?

Markup % = (selling price − cost) ÷ cost × 100. To go the other way, selling price = cost × (1 + markup% ÷ 100).

Is markup the same as profit margin?

No — markup is profit as a percentage of cost, while margin is profit as a percentage of selling price. A 50% markup on a $50 cost gives a $75 price, but that's only a 33.3% margin, not 50%. See the Margin Calculator for the margin version of this math.

How do I find my cost if I only know the price and markup I want?

Use the "Price + markup → cost" mode: cost = price ÷ (1 + markup% ÷ 100). This is handy for reverse-engineering what you can afford to pay a supplier for a target retail price and margin.
