Price Per Unit Calculator
Compare prices by unit to find the best deal

// Bigger Isn't Always Better
Bulk sizes often have a lower unit price, but not always. Some retailers charge more per unit for "family size" packs. Always check the unit price.
// Shelf Labels
Most supermarkets show the price per unit (per 100g, per litre) on shelf labels. Use this calculator when shopping online or at stores that don't display it.
// Consider Waste
A cheaper bulk option isn't a deal if half of it expires before you use it. Factor in shelf life and your actual consumption when comparing.
// Unit Consistency
Make sure you compare the same units — grams to grams, ml to ml. A 500g pack vs a 1 litre bottle aren't directly comparable without converting.
