Price Comparison Calculator – Unit Price

Price comparison calculates the cost per unit (ounce, gram, count) for different products or package sizes. The lowest unit price represents the best value, though you should also consider freshness, storage, and whether you'll use the larger quantity. Worked example: a 24-pack priced $18.96 works out to $0.79 per can, while the 12-pack at $10.20 is $0.85 per can — the bigger pack saves $0.06 × 24 = $1.44. Compare per ounce, per liter or per item and package size illusions disappear.
