Don’t Bank On Percentages
Posted in Business by Jesse
When running a small business it’s easy to be seduced by the siren song of percentages. Many owners concern themselves with percentages of COGS and gross profit margin, basing important merchandising decisions on rules of thumb. Often they’re businesses are dashed on the rocks of bankruptcy, all because they neglected the more important dollar amount of gross-profit margin.
The difference between percentages and hard dollars is not an academic argument. It could very well mean the difference between profitabilty and financial insolvency. Consider the following scenario:
A small business owner buys widget X at $1 and sell it for $4.
- markup = $4/$1 = 4X
- gross profit = $4 - $1 =$3
- gross-profit margin = $3/$4 = 75%
Now, that same business person see’s widget X with extra features and trapping being sold at $4 from their wholesaler. Most owners would mentally calculate that they’d have to sell the product at $16 (4X markup). While the extra features make the widget X greatly improved, they know no sober will pay that money, so they don’t stock improved widget X.
Why didn’t they think about selling it for $8?
- markup = $8 / $4 = 2 X
- gross profit = $8 - $4 = $4
- gross-profit margin = $4 / $8 = 50%
For the same amount of effort a $4 gross profit and better than $3. Yet many small businesses don’t see it that way.
They stick to old rules of thumb, thinking that a 2X markup is worse than 4X, and keep selling products that net them a lower gross profit. They’ve been seduced by the sirens song.

I like how Wegmans is tackling an increasingly price conscious consumer with their comparison shopping signs.
