Unit Price Calculator

Compare two products by price per unit to see the better deal. Nothing leaves your browser.

How it works

Enter the price and quantity (same unit) for both items. Unit price = price ÷ quantity. The cheaper unit price is the better deal.

FAQ

How do I compare unit prices?

Divide each price by its quantity. For $3 for 12 and $5 for 24, the unit prices are $0.25 and $0.2083, so the 24-pack is cheaper per item.

Can I compare different sizes?

Yes, as long as both quantities use the same unit, for example both in ounces or both in grams. Convert first if the units differ.

Is the cheapest unit price always the best buy?

Not always. Check expiry dates, storage space and whether you will use it all before it goes off.

Is my data uploaded?

No. Everything is calculated in your browser and nothing is sent or stored.
