Unit Price Calculator: Which Is the Better Deal?

Enter the price and quantity of two products to compare their cost per unit.

Formula

Unit price = Price / Quantity

Worked example

500 g for 3.49 costs 0.70 per 100 g; 1 kg for 5.99 costs 0.60 per 100 g, so the larger pack is cheaper.

Frequently asked questions

Is the bigger pack always cheaper?

No. Promotions on small packs often beat large packs, which is why comparing unit prices helps.

Can I compare different units?

Use the same unit for both products, for example grams for both.

What does price per 100 units mean?

The cost of 100 grams, 100 ml or 100 items, which makes small prices easier to compare.
