Margin and markup are not the same thing, and confusing them can cost a store money

[Viable Food]

Margin and markup are often used as if they mean the same thing.

They do not.

That distinction matters because grocery pricing is already difficult enough without using the wrong number.

Markup looks at the profit added compared with cost.

Margin looks at gross profit as a percentage of the selling price.

For a simple example, imagine an item costs the store $8 and sells for $10.

The gross profit is $2.

The markup on cost is:

$2 ÷ $8 = 25%

The gross margin is:

$2 ÷ $10 = 20%

Same item. Same cost. Same price. Two different percentages.

This becomes important when someone says, "We need a 30 percent margin," but the pricing process actually adds 30 percent to cost.

Those are not equivalent.

It also matters because grocery stores do not pay payroll, utilities, insurance, card fees, repairs, shrink, and every other operating expense out of sales. Those expenses ultimately have to be supported by the gross profit dollars left after product cost.

The purpose of pricing is not to chase the biggest possible percentage on every item. It is to build a pricing structure that customers can accept while generating enough gross profit to support the business.

That requires knowing which number you are actually using.

Have you ever worked somewhere that used "margin" and "markup" interchangeably? How did the store set prices in practice?
