Measure an eyewear fixture by the gross-profit dollars it contributes over a defined period, not by markup percentage alone.
Use the basic calculation
Net eyewear sales - landed product cost = gross-profit contribution. Include discounts and markdowns in net sales, and include freight or other relevant landed-cost components when comparing programs.
Then connect profit to the fixture
Compare gross-profit contribution with the footprint, inventory investment, and staff time required. This gives a more useful view of space productivity.
Track the drivers behind the number
- units sold
- average retail price
- landed cost
- markdowns
- stockouts
- inventory aging
- reorder frequency
Do not reward understocking
A fixture with strong profit but frequent core stockouts may have more potential than the measured result shows. Use availability data alongside the financial number.
Compare periods consistently
Use the same time window when comparing two locations, fixture sizes, or categories.
