How I compare unit prices when pack sizes differ

A larger package is not always cheaper. Unit price comparison puts products on the same scale.

The Unit Price Comparator tool handles the repetitive part so I can focus on checking whether the result makes sense.

The simple idea

A larger package is not always cheaper. Unit price comparison puts products on the same scale.

I still treat the output as something to review, especially when it affects money, dates, privacy, or production data.

My checklist

Before I trust the result, I check:

• Enter each product price.
• Enter the quantity or size.
• Choose the same unit for every item.
• Compare price per unit.
• Watch for different units like grams and kilograms.
• Include shipping or fees when they matter.
• Use the result as a guide, then consider quality and waste.

A small tool is most useful when it makes the work visible and easy to verify.
