Which one is the better deal
Grocery and bulk prices are hard to compare when sizes differ. Enter each option’s price and its amount in the same unit (grams, ounces, items…) and the tool shows the price per unit for each and highlights the cheapest. Add as many options as you want.
Same unit, fair comparison
For a valid comparison, measure every option in the same unit — convert 1 kg to 1000 g, or 2 lb to 32 oz, before entering. The maths is simple division, done instantly in your browser with nothing uploaded.
Frequently asked questions
How do I calculate price per unit?
Divide the price by the amount. $3 for 500 g is $0.006 per gram. The tool computes this for each option and flags the lowest.
Why must the units match?
Comparing per-gram to per-ounce is meaningless. Put every option in the same unit first, then the lowest price-per-unit is the best value.
