ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

Compare two products by their true price per unit (per gram, per litre, per piece) to instantly see which one is actually the better deal, regardless of pack size. A 1kg pack priced at PKR 950 works out to PKR 950 per kg, while a 750g pack at PKR 720 works out to PKR 960 per kg — despite looking cheaper on the shelf, the smaller pack is actually the worse deal per unit.

How to use Unit Price Comparison Calculator

Step-by-step guide to the boxes below. Open it only if you need help.

  1. 1
    Product A price Number

    The total price of the first pack, as printed on the shelf.

    Example: 500

  2. 2
    Product A qty Number

    How much is inside that pack (grams, millilitres or pieces).

    Example: 1000

  3. 3
    Product B price Number

    The total price of the second pack.

    Example: 850

  4. 4
    Product B qty Number

    How much is inside the second pack. Use the same unit as Product A: if A is in grams, B must be in grams too.

    Example: 1800

  5. 5
    Press “Compare”

    Click the button under the boxes. If something is missing or not valid, a short message tells you which box to fix.

  6. 6
    Read your result

    The tool tells you which pack is cheaper per unit and by how much. Change any box and try again to compare different numbers.

Unit Price Comparison Calculator FAQs

What if the two products have different units (grams vs ml)?
Convert both to the same unit first, then enter the quantities — the calculator just needs matching units to compare fairly.
Does a bigger pack always win?
Not always — sometimes smaller packs are on sale and end up cheaper per unit. That is exactly why comparing unit price is useful.
Why do stores show unit price on shelf labels?
Many stores are required to display unit pricing so shoppers can compare value across different pack sizes and brands at a glance.
Can I compare more than two products at once?
This version compares two at a time — for more items, run the comparison in pairs, or note down each unit price and compare manually.
