How to Find the Best Value
Smart shopping isn't just about looking for the lowest price tag; it's about finding the best unit price. Manufacturers often use "downsizing" or varying packaging sizes to make it difficult to compare costs at a glance.
Why Unit Pricing Matters
A large bottle of laundry detergent might seem like a bargain because it's on sale, but if you calculate the price per ounce, a smaller twin-pack might actually be cheaper. This calculator removes the guesswork by normalizing different quantities into a single unit price.
Unit Price = Total Price / Quantity
How to Calculate Price Per Unit
- Price Per Ounce: Divide the cost by the number of ounces (e.g., $4.99 / 16oz = $0.31/oz).
- Price Per Kilogram: Divide the price by the weight in kg.
- Bulk vs. Single: Always check if the "Family Size" actually offers a discount or if it carries a convenience premium.
Frequently Asked Questions
What is unit price?
Unit price is the cost of a single unit of measure of a product. This could be per weight (ounce, gram, pound), per volume (milliliter, liter, fluid ounce), or per count (sheet of paper, individual diaper).
Is buying in bulk always cheaper?
Not always. While retailers often discount larger quantities, "unit price creep" can happen where bulk items are priced higher than smaller ones due to perceived value or convenience. Always use a calculator to verify.
