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
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.

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.
