Margin math for impulse supplements: why counter space beats shelf space
How to compare a till-side sachet with a shelf bottle: margin per unit, turns per month and revenue per square centimetre of counter.
- Judge an impulse product by turns, not by margin per unit: a sachet that sells twenty times a month beats a bottle that sells twice.
- Counter space is the scarcest space in the store; measure revenue per square centimetre, not per facing.
- Trial-to-repeat is the model: the single sachet buys the customer, the 3-pack keeps them.
- A display box is both the stock and the fixture, so there is no merchandising cost to recover.
Retail buyers are trained to look at margin per unit. For impulse supplements that is the wrong number. Here is the arithmetic that matters, with HIIRS as the example.
Turns, not margin
A 60-capsule bottle at a high shelf price with a healthy margin might sell two units a month. A single-serve sachet at an impulse price might sell twenty. Multiply margin by turns and the sachet wins, even though each unit earns less.
The display box makes the comparison concrete: 20 sachets per box, one box per till. Count the boxes you reorder per month and multiply by the margin per box from the price list. That is the number to compare against the bottle.
Revenue per square centimetre
The counter is the most valuable surface in the store and usually the least measured. A display box occupies roughly the footprint of a chewing-gum stand. Divide monthly revenue from the box by that footprint and compare it with any shelf product per facing. Few shelf products come close.
Trial to repeat
The 1-strip sachet is the acquisition cost. Customers who like it come back for the 3-strip sachet, which carries a higher basket value and a better margin per transaction. Over a quarter, track the ratio of 3-packs to singles; when it crosses one, you have a repeat-purchase product on the counter.
No fixture cost
Most impulse products need a stand, a clip strip or a branded tray. The HIIRS display box is the fixture: rigid board, printed, folds open. Nothing to buy, nothing to assemble, nothing to recover.
What to ask for
Request the price list and the logistics sheet together. The price list gives margin per sachet and per display box at each tier; the logistics sheet gives units per case, so you can see the cash tied up per reorder. With both, the counter-versus-shelf comparison takes five minutes.
