PerUnitPrice
PerUnitPrice compares unit prices in the aisle.
Is the 24-pack at $18.99 actually cheaper than the 12-pack at $10.49? PerUnitPrice answers that in the aisle, in seconds: type two prices and two amounts, and the verdict appears — which one wins, by how much, and what each really costs per unit.
- No Compare button — the answer appears the moment both items are filled in.
- Mixed units handled: oz vs lb, g vs kg, fl oz vs liters, pack sizes like 24 cans × 12 fl oz.
- Pro remembers what you paid, by product and store, and compares three or more items side by side.
- The full calculator is free forever — every unit, exact math, no ads, no watermarks.
The calculator is free; Pro is a single $2.99 purchase for saved prices and bigger compares.
