About Unit Price Calculator

Compares the per-unit cost of multiple products to identify the best value. Enter price, quantity, and unit of measurement (oz, lb, g, kg, L, mL, count, or custom) for each item, and the calculator divides price by quantity to produce a cost-per-unit figure to four decimal places. The lowest unit price across all items is highlighted as “Best Value.” Add unlimited products for comparison.

• Automatic “Best Value” badge on the product with the lowest unit price (only when comparing two or more)
• Add and remove products dynamically—no fixed limit
• Copy results as formatted text or export to .txt file

Frequently Asked Questions

Does it convert between different units?

No. It calculates price per unit for whatever unit you specify, but it won’t convert ounces to grams for cross-unit comparison. For accurate comparisons, enter all items in the same unit.

Why four decimal places?

Unit prices on small quantities (like cost per gram or per mL) often differ only in the third or fourth decimal place. Four decimals ensure you can see meaningful differences when comparing similarly priced bulk items.
