How to use the unit price calculator
- Enter each product with its price and pack size (grams, kilograms, ml, litres, pounds, ounces or pieces).
- The price per kg, litre or item is calculated for every row.
- The best value is highlighted in green, with how much cheaper it is than the most expensive option.
Bigger packs are not always cheaper and “special offers” can hide a higher unit price. Compare supermarket products, washing powder, coffee, baby formula or fuel cans quickly. Different measures (g vs kg, ml vs L) are converted automatically.
