How to compare unit prices without getting caught by pack sizes

Supermarket prices can be confusing because the cheapest-looking pack is not always the best value. Unit pricing gives you a fairer comparison.

Food: kg and litres

Meat, fish, vegetables, fruit, rice, pasta, milk and yoghurt are usually easiest to compare per kg or per litre. This lets a small pack and a family pack sit beside each other fairly.

Household: wash, bag or item

Laundry capsules should be compared per wash, not just by pack price. Bin liners should be compared per bag, with the litre size visible where possible. Toiletries and tablets may make more sense per item or per 100ml depending on the product.

Why NI Food Compass shows the retailer link

The site can help spot value, but the retailer is still the final source for stock, delivery, local price and promotion details. Every row should point you back to the shop for checking before you buy.
