The ROI's GMROI Calculator

Gross Margin Return on Inventory Investment

Compare your inventory productivity BEFORE you place the order!

Unlimited access for Members, 24/7.



Enter your planned sales and margins - by store, by department, by vendor, even by customer group! - and immediately see the GMROI for each one. 

Quickly compare and contrast the relative productivity of each grouping. Which ones are providing a good return on your inventory investment? Which ones are lagging behind in productivity?


"What would happen if I...?"

Then, make some changes. Increase margins? GMROI goes up. Hmmm....Increase turns? GMROI really goes up!  Or, increase both, and see what synergy is all about! 

Now, you have a plan. You can focus your buying - and your negotiations with your vendors - where you will get the best return on your investment.
