About the Unit Price Comparator

Unit price comparison is the shopper's superpower. Supermarkets and apps rarely show price per 100g or per ml prominently - they rely on confusion between pack sizes to encourage purchasing the less economical option. A 750ml bottle of cooking oil at ₹120 vs a 1L bottle at ₹150 looks obviously cheaper, but the unit price reveals: ₹16/100ml vs ₹15/100ml - the larger bottle wins. This tool makes that math instant.

Unit Price Comparison

Unit price = Total price / Quantity · Compare unit prices in the same unit after converting

Convert all to same unit before comparing: 500g vs 1.5kg - convert both to per 100g · Price per piece = total price / number of pieces · Price per liter = total price / volume in liters

Worked Example

Comparing 3 packs of atta: 2kg at ₹95, 5kg at ₹220, 10kg at ₹425

2 kg pack:₹95 = ₹47.5/kg
5 kg pack:₹220 = ₹44/kg
10 kg pack:₹425 = ₹42.5/kg

Cheapest per kg: 10 kg pack (₹42.5/kg) · But only better if you will use it before it spoils · 5 kg vs 2 kg: saves ₹7/kg = ₹14 on a 2 kg purchase

Tips & Insights

  • 1

    Unit price comparison often reveals that store-brand products at 20-30% lower unit prices match national brand quality.

  • 2

    For perishables, factor in likely wastage - a cheaper per-unit price on a large pack is not better if 30% will spoil.

  • 3

    Hygiene and personal care products (shampoo, soap, detergent) almost always have better unit prices in larger packs.

Why this matters for you

Indian households spend approximately 30% of income on food and household goods. Consistently choosing the best unit price - which takes 10 seconds with this tool - can save 5-10% on this category, translating to ₹2,000-₹5,000 per year for a typical middle-class family. Over a decade, that is a SIP that could become ₹3-7 lakh.
