How it works

Shops show prices for different pack sizes, which makes them hard to compare. Unit price turns every pack into the same measure, such as rupees per kg, so the cheapest one is clear. Discounts and bonus quantities are folded in.

Cheapest is not always best
A big pack only saves money if you finish it before it spoils or expires.

Price per kg = amount you pay ÷ quantity you get, with any discount taken off the price and any free extra added to the quantity.
Offer pack: ₹99.00 ÷ 0.6 kg = ₹165.00 per kg.

Use the same size unit for all rows: all grams, all ml or all pieces.
Count 'Buy 1 get 1 free' as 100% extra free.
Add delivery or handling fees to the price if they differ between packs.

Price per base unit = price × (1 − discount) ÷ (size × unit factor × (1 + extra free)). Grams and millilitres convert to kg and litres by dividing by 1,000; pieces are compared per piece. Packs are ranked from lowest to highest price per unit.

What are the limits of Unit Price Comparison?

Compares price only: it cannot tell you about quality, expiry, storage or whether you will use a bigger pack before it spoils. Delivery fees are not included unless you add them to the price. Nothing you enter leaves your device.
