Unit price calculator
Compare two packages to see which costs less for the same quantity.
Use one currency for both prices. Prices: 0–1,000,000,000; quantities: 0.000001–1,000,000,000. Compare only the same type of quantity. No thousands separators.

How it works
Choose weight, volume or item count, then enter each package’s price and quantity. A 750 g package costing 3 costs 4 per kg. A 1 kg package costing 3.50 costs 3.50 per kg, so B has the lower unit price.
Good to know
What does the percentage saving mean?
It compares the lower unit price with the higher one: (higher − lower) ÷ higher × 100. It does not compare total checkout prices or product quality. Only grams/kilograms, millilitres/litres and item counts are supported, so incompatible measurements cannot be mixed. Displayed unit prices use four decimal places; very small differences can round to the same displayed value.
