GMROI

GMROI is what a dollar of inventory earns, margin and turnover refereed into one return on stocked capital.

What GMROI is

GMROI, gross margin return on inventory investment, is what a dollar of stock earns: gross margin for the period divided by average inventory cost, the return on the money sleeping on shelves.

Why GMROI matters

Margin and turnover argue when judged alone: the rich-margin slow mover versus the thin-margin fast mover both claim to be working. GMROI is the referee, combining how much each sale earns with how often the inventory earns it, so buying decisions compare products by return on the capital they tie up.

Using GMROI

Rank categories and products by it: the buying budget’s honest league table
Diagnose low scores: a margin problem, a turnover problem, or both
Steer the mix: reorder depth and space toward the earners
Watch it through promotions: discounts that lift turnover can still sink GMROI

Frequently asked questions

What’s a good GMROI?

Above one is table stakes, each inventory dollar returning more than itself in margin, and the working target varies by category economics. As with turnover, the useful comparison is your products against each other and your own trend, not a borrowed benchmark.

GMROI or inventory turnover: which to steer by?

Turnover measures speed; GMROI measures pay: a product can turn fast while earning little. Buyers use turnover for stock health and GMROI for allocation, where the next buying dollar earns most.
