Compare pack prices per 100 g, 100 ml or per item to find the best value. Works with $ £ €.
Enter the price and pack size for two to four products and the tool normalises each one to a standard amount — per 100 g, per 100 ml, or per item. Deals like 2 for £3 and multipacks like 4 × 500 ml are handled with the for and packs fields, and the best-value product is highlighted automatically.
Choose your currency, then fill in the price, deal quantity (for), pack size, unit and number of packs for each product. Results update as you type: each row shows its price per 100 g, 100 ml or item, the best-value row is marked, and the others show how much more expensive they are.
The price of a product per standard amount — per 100 g, per 100 ml, or per item. Unit prices let you compare packs of different sizes fairly, and many countries require them on shelf labels.
Use the for field for deal quantity (2 for £3 → price 3, for 2) and the packs field for multipacks (4 × 500 ml → size 500, packs 4). The tool multiplies them out before comparing.
Weight (g, kg, oz, lb), volume (ml, L, fl oz) and single items. All products in a comparison must share the same unit type — the first product’s unit sets it. Fluid ounces convert at 28.41 ml (UK).
