65% Margin on a Product Nobody Buys Is Not a Win

A homewares retailer once walked me over to a shelf like he was introducing me to his firstborn. “This range,” he said, “sixty five percent margin. Best in the store.” He’d been carrying it for fourteen months.

I asked how many units he’d sold. He didn’t know. We pulled the report together. Eleven units. In fourteen months.

Sixty five percent margin on eleven units is not a good product. It is money sitting on a shelf collecting dust and pretending to be an asset.

A high margin percentage feels like proof of a good decision. It tells you nothing about how hard that stock is working for the cash you tied up in it.

The number that matters is GMROI: gross margin return on inventory. Take your gross margin dollars for a product over a year, divide by what you paid for the average stock you held. That tells you how many dollars of margin you generated for every dollar parked in inventory.

Ten thousand dollars of stock at sixty five percent margin, turned once a year, returns about six and a half thousand. The same ten thousand at twenty percent margin, turned six times, returns twelve thousand. Turnover multiplies margin. Margin without turnover just sits there.

There is a place for slow moving, high margin items: a showpiece, a genuine point of difference. Fine. Know you are funding it on purpose, instead of discovering it by accident when the warehouse is full.

GMROI varies enormously by category, which is the point. A grocer turns stock often enough that a thin margin still works. A furniture retailer needs a much fatter margin to match it. Comparing a jeweller’s GMROI to a fruit shop’s is not analysis. It is theatre.

A buyer valuing your business eventually looks past revenue and margin percentage straight at how efficiently your capital is working. Slow, fat-margin stock looks weaker on paper than lean-margin stock turned hard.

Most owners can tell you their best selling product by units. Almost none can tell you their best performer by GMROI. That gap is where profit quietly leaks out for years, unnoticed.

Go back to whatever you are proudest of on your shelves right now. Work out the GMROI. If the number embarrasses you, you have just found the fastest improvement available to your business this quarter.

That homewares retailer eventually cleared the range at cost. He said it felt like defeat. It was the first profitable decision he had made about that shelf in over a year.
