Why unit price beats the sale sign
"Family size" and "2 for $5" labels don't always mean cheaper. The unit price — cost per 100 g, per litre, or per item — is the only fair comparison across sizes and brands.
When the bigger pack isn't worth it
- You won't finish it before it spoils.
- A smaller size is on sale below the bulk unit price.
- Storage space or cash flow is tight.
FAQ
How is unit price calculated?
Unit price = price ÷ quantity, converted to a common unit. We normalise to per 100 g, per 100 ml or per item.
Can I compare ounces with grams?
Yes — we convert oz, lb, kg and g to a common base automatically. Fluid ounces are converted as volume.
