Unit Price Comparison

Find the best value product instantly

Enter the price and quantity of each product you are comparing — such as a 400 g tin at one price and an 800 g tin at another. The calculator divides price by quantity to find the cost per unit for each item and highlights the cheapest in green. This works for any unit (g, kg, L, ml, sheets, pieces) as long as all items use the same unit.

Add as many items as you need. The comparison updates as you type, so you can quickly work through a supermarket shelf or a list of online offers. Select your local currency from the selector so prices display correctly.

FAQ

Can I mix units, such as grams and kilograms? No — the tool compares price per unit directly, so all items must use the same unit. Convert quantities to a common unit before entering them.

What if two items have the same price per unit? Both are marked as cheapest.
