6 Ways Unit Pricing Changes What You Buy
Supermarket pricing makes direct comparison difficult by varying pack sizes, formats and promotions, and the unit price is the tool that cuts through it.
1. What it is
The price expressed per standard measure — per kilogram, per litre, per hundred grams, per item.
It is displayed on shelf labels in most regulated markets, usually in smaller type than the headline price.
It allows two products in different pack sizes to be compared in one step.
2. Where it changes the answer
Larger packs are usually cheaper per unit and not always, particularly when a smaller size is on promotion.
Multibuy offers frequently work out more expensive per unit than a single larger pack.
Premium and own-brand versions of an identical product can differ by a multiple, which the unit price exposes immediately.
Products sold by item rather than weight — bread, eggs, produce — need the same check, since the measure differs.
3. Traps to watch
Different measures on adjacent products, such as one priced per hundred grams and another per kilogram, which prevents direct reading.
Concentrated products, where the diluted cost is what matters rather than the bottle price.
Packaging weight included in some measures and not others.
Shrinkflation, where the pack size falls while the price holds. The unit price rises even though the shelf price looks unchanged.
4. Beyond price per unit
Waste matters. A larger pack is only cheaper if it is used before it spoils.
Storage capacity limits how much bulk buying is practical.
Frozen and tinned alternatives are frequently cheaper per unit and have far longer usable life.
5. Building the habit
Check the unit price on the ten or fifteen items you buy every week; that covers most of the shop.
Note the best value option once and stop re-deciding each time.
Compare across shops for those staples only, rather than trying to optimise an entire basket.
6. Promotions
A promotion that reduces the unit price below your usual option is a genuine saving.
One that does not is a price presentation.
Loyalty pricing has become common, where members pay less; the unit price shown may assume membership, which is worth checking.
Final Thoughts
Unit pricing is the one number in a supermarket that allows genuine comparison. Check it on the fifteen items you buy every week, decide once, and stop re-deciding on every shop.
