Frequently Asked Questions

How do I calculate unit price?

Unit Price = Total Price ÷ Quantity. For example, a 2kg bag for 500 has a unit price of 250 per kg.

Why does the bigger pack sometimes cost more per unit?

Not always, but sometimes — packaging, brand, or "convenience size" pricing can make a larger pack more expensive per unit than a smaller one. This is exactly why comparing unit price, not just total price, matters when shopping.

Does this work for any unit (kg, litres, items, etc.)?

Yes — enter quantities in the same unit for both products (e.g., both in kg, or both in litres, or both as item counts) and the calculator gives you a comparable price per unit for each.
