Unit Price Calculator

Compare price per unit — find the deal.

Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.

Enter the price and size of each product to see its price per unit — side by side — with the best value highlighted. Compare different package sizes or brands at the shelf and stop doing the math in your head.

Frequently asked questions

What units can I compare?

Any — as long as the items share a unit. Enter the size (oz, g, ml, L, items) and the price; the per-unit cost is computed and the cheapest is flagged.

Can I compare more than two products?

Yes — add as many rows as you like; they are all ranked by price per unit.

Is my data saved?

No — it is calculated in your browser only.
