Summary
About this tool
Compare pack sizes, brands and shops to find the cheapest way to buy an ingredient. Enter the pack price and its size in grams, kilos, millilitres, litres, ounces, pounds or items, and see the price per kilo, litre or item and how much cheaper the best option is. Everything stays in this browser.
How it works
- Each pack size is changed to kilograms, litres or items: g and ml are divided by 1,000, 1 oz is 0.028349523125 kg and 1 lb is 0.45359237 kg.
- The unit price is the pack price divided by that converted amount.
- Options with the same ingredient name are compared only when they are measured the same way (weight, volume or items). If they are mixed, the kind used by most options is compared.
- Cheaper than the dearest by is 1 minus the cheapest unit price divided by the dearest, times 100.
Common questions
Can I compare a pack sold by weight with one sold by volume?
No, because a litre of a food does not always weigh a kilo. Enter both the same way, using the weight or volume printed on the pack.
Is the biggest pack always the best buy?
Not always. A big pack only saves money if you use it before it goes off, and small packs on offer are sometimes cheaper per kilo.
Why is one of my options left out?
It may have a pack size of zero, a different kind of unit from most options for that ingredient, or a slightly different ingredient name. Use the same name for every option you want compared.
