Frequently Asked Questions

What is the difference between margin and markup?

Margin is profit as a share of selling price; markup is profit as a share of cost. Example: cost $80, price $100 → margin 20%, markup 25%. Same profit, different base — mixing them up is the most common pricing error.

How do I work backwards from a target margin?

Enter your cost and target margin %; the calculator solves for price. Example: cost $80 with a 30% target margin → price = $80 / (1 − 0.30) = $114.29.

Which inputs do I need?

Two: item cost and target margin %. The calculator solves for selling price, profit, and markup — it does not take selling price or markup as inputs.

Does it handle taxes or discounts?

Enter tax-inclusive or post-discount figures directly. For a 10% discount off a $100 list price, run the numbers on $90 to see the true margin before quoting.

Is my pricing data stored?

No. All calculations run locally in your browser. No costs, prices, or margins are transmitted or stored.
