Which Pack Is Really Cheaper?

Best Uses
- Groceries (rice, flour, oil, milk)

- Supplements and protein powders

Frequently Asked Questions
What is unit price?
The price per standard unit (per kg, per litre, per 100g, per piece). It's the fairest way to compare two packages that differ in size.
Is bigger always cheaper per unit?
Usually, but not always. "Family packs" sometimes cost more per unit than the regular size. This tool settles the question in seconds.
Can I compare different units (kg vs g, L vs mL)?
Yes. Enter each product's own unit and quantity — we normalise both to the same base for a fair comparison.
Does this include taxes and delivery?
Put the final price you'll pay (after tax / delivery / offers) to make sure the comparison reflects what leaves your wallet.
