How It Helps

Compare products by actual unit price, not just shelf price.

A lower shelf price does not always mean a better deal. This calculator helps you compare cost per unit, price per gram, or price per ml so you can quickly see which option gives better value for your money.

It works well for grocery shopping, supermarket comparisons, household supplies, drinks, and bulk items where package sizes make direct price comparison difficult.

How To Use It

How to calculate cost per unit

Enter the product price and the quantity in items, grams, or milliliters. The calculator divides price by quantity to show the cost per unit, then highlights the option with the best value.

This makes it easier to compare different pack sizes and prices when shopping, especially when products are not sold in matching quantities.
