Pricing & Margin

Computes gross margin and markup from cost and price — two numbers people constantly confuse — and shows the brutal volume math behind discounting at your margin.

The operator’s read

Worth knowing

Margin (40%) is profit over *price*; markup (66.7%) is profit over *cost*. Mixing them up is the most common pricing spreadsheet error — a "50% markup" is only a 33% margin.

Methodology

Margin = (price − cost) ÷ price; markup = (price − cost) ÷ cost. They describe the same gap against different bases.

Discount volume math: required volume multiplier = original per-unit profit ÷ discounted per-unit profit. Because a discount reduces profit one-for-one while cost stays fixed, low-margin products need enormous volume lifts to justify small discounts.

This is unit-level analysis — it deliberately excludes demand elasticity. It answers "what volume would I need", not "what volume will I get".
