How it works
On the supermarket shelf the bigger pack is not always the better deal. The only fair way to compare is the price per unit — per kilo, litre or item.
Enter the price and quantity of each product and the calculator finds which costs less per unit, and shows the percentage you save.
That way you avoid the trap of the "value" pack that actually costs more per kilo.
Frequently asked questions
Do the products need the same unit?
Yes, for a correct comparison use the same unit (e.g. both in grams, or both in litres).
Does it consider quality?
No — it compares price per unit only. Quality and preference are for you to judge.
Why is the bigger pack sometimes worse value?
Retailers know shoppers assume bulk is cheaper, so a "family" or "value" size occasionally costs more per kilo or litre than the standard one. Comparing the unit price is the only way to be sure.
