Formula & Theory — Unit Price Calculator
The Unit Price Calculator is based on the fundamental relationship between price, quantity, and unit cost:
Unit Price = Total Price ÷ Quantity
Total Price = Unit Price × Quantity
Quantity = Total Price ÷ Unit Price
| Symbol | Meaning |
|---|---|
| Unit Price | The price for a single item or unit of measurement |
| Total Price | The overall cost for all units combined |
| Quantity | The number of items or units purchased |
Why Unit Price Comparison Matters
Retail products are sold in many different pack sizes, weights, and volumes, making direct price comparison difficult. By reducing everything to a common unit price, the Unit Price Calculator creates a level playing field. This technique — sometimes called "price per unit" or "cost per unit" labeling — is mandatory in many jurisdictions for supermarket shelf tags and is an essential tool for smart consumer decision-making.

The Unit Price Calculator is useful whenever you need to translate a bulk or packaged price into individual cost:
