Unit Price Comparator
Compare unit prices to find the better deal.
Which size is actually cheaper?
The bigger package is not always the better value. Dividing price by quantity gives a unit price you can compare directly — $3 for 500 g beats $5 for 750 g.
Supermarkets already print unit prices, but this settles the awkward cases — different units, bulk versus single, or a promotion — where the shelf label does not compare cleanly.
Match the units
Compare like for like (per 100 g, per litre) for a fair result. The math runs entirely in your browser. The prices you enter are never uploaded.
