Unit Price vs Sticker Price (Grocery Math)

**Sticker price** is what you pay at register. **Unit price** (per oz, per sheet) reveals true value across package sizes—essential for bulk vs small pack decisions.

Step by step

1. Normalize units

Convert lb to oz if labels differ.

2. Include waste

Peel waste or unusable portion adjusts real unit cost.

3. Storage cost

Bulk saves only if you use before spoilage.

Unit vs total

Unit price wins comparison; total price determines cash flow.

  • Unit price: Best for comparing sizes.
  • Total price: What leaves your wallet today.

Common mistakes

  • Ignoring expiration
  • Comparing different unit types

FAQ
