Enter the price, quantity, and unit for two products to compare their unit prices and find the better value.
How to Use the Unit Price Calculator
Enter each product's price, quantity, and a unit label (like "oz" or "count"), then compare the two unit prices and the labeled better-value result below.
Unit Price = Price ÷ Quantity
Savings / Unit = |Unit Price A − Unit Price B|Package sizes are the classic trick in grocery-store pricing — the bigger box isn't automatically the better deal, and shelf tags don't always make the per-unit comparison easy to see at a glance, especially when the two sizes being compared aren't round multiples of each other.
A 32 oz bottle at $4.99 works out to about 15.6 cents an ounce; a 48 oz bottle at $7.49 comes out just a hair higher, around 15.6 cents as well — close enough that the "bulk size is always cheaper" assumption doesn't actually hold here. That's the entire reason this calculator exists: eyeballing two different price-and-size combinations rarely gives a reliable answer.
The unit labels are free text, not linked units — this compares dollars per whatever quantity you entered for each product, so it only produces a meaningful comparison when both quantities are measured the same way (both in ounces, both a count of items, and so on).
