Unit Price Comparator
Bigger isn't always cheaper. Compare the price per unit (per ounce, gram, or count) of two package sizes to find the better buy — just use the same size unit for both options.
Inputs explained
- Option A price — Shelf price of the first package.
- Option A size (oz, g, count…) — How much is in the first package.
- Option B price — Shelf price of the second package.
- Option B size (same unit) — How much is in the second package, in the same unit as Option A.

Understanding the result
Example: A 16 oz jar at $5.00 costs $0.3125/oz while a 24 oz jar at $8.00 costs $0.3333/oz — Option A is 6.3% cheaper per ounce.
Frequently asked questions
What happens if I enter Option A and B in different units, like ounces and grams? The comparison only works if both sizes use the same unit; mixing units (e.g., one in ounces, one in grams) will produce a misleading unit price since the tool doesn't convert between them.
Does a lower total price always mean the better deal? No, the larger or cheaper-looking package can still cost more per unit; this calculator compares price per unit specifically so package size doesn't distort the comparison.
