The 12 That Becomes 44, and Nobody Took More Than Half

Margin and markup are different numbers for the same step

Going from 12 to 20 is a 40 % margin and a 66.7 % markup — the first divides by the selling price, the second by the cost, and they describe exactly the same move. The confusion is expensive in one specific direction: a maker told to "add 40 %" who multiplies cost by 1.4 prices at 16.80 instead of 20, and gives away two fifths of the intended margin without noticing. State which of the two you mean every time, because the words are used interchangeably by people who do not mean the same thing.

Keystone is a 50 % margin, not a 100 % one

Doubling the wholesale price — the old retail habit called keystone — would put this item at 40, which is a 50 % margin on the shelf price. The retailer asking for 55 % is therefore pricing above keystone, at 44.44, and the extra 4.44 is the difference between an old rule of thumb and a modern cost base with rent and returns in it. Knowing that keystone equals exactly 50 % is the fastest way to sanity-check any wholesale conversation: anything a retailer quotes above that is a request, not a convention.

Frequently asked questions

Can I sell direct at the wholesale price?

You can, and it is usually a mistake. Selling direct at 20 when retailers stock the same item at 44.44 destroys their reason to carry it, and they will drop the line long before your own channel replaces the volume. It also hides that direct selling costs money: the payment fees, the packing, the returns and the acquisition of each customer are the work the retailer's margin was paying for. Price direct at or near the shelf price and treat the difference as the budget for doing the retailer's job yourself.

What belongs in the unit cost?

Everything that scales with each unit made: materials, the labour that touches the product, packaging, and the freight that brings the components in. Rent, machinery and salaries stay out, because they do not change when one more unit is produced — which does not mean they are free, only that they are covered by the margin rather than by the cost. A common error is to include a slice of the rent per unit, which makes the cost move whenever volume moves and produces a price that rises exactly when sales fall.
