What this worksheet is for
Compare products by price per standard unit before choosing the cheapest-looking pack. The worksheet turns that goal into a repeatable record, so later decisions are based on the same fields rather than memory or scattered notes.
What is included
- Product price, pack quantity and standard unit for each option
- A calculated price per 100 g, kilogram, litre, item or other comparable unit
- Notes for quality, waste, storage and whether the larger pack will actually be used
How to use it
- Convert every pack to the same unit before comparing.
- Use the quantity that is actually usable; drained weight or concentrated products can make the front-of-pack size misleading.
- Check whether a cheaper unit price creates waste, storage problems or a larger upfront spend.
Worked example
A 750 g pack for $9 costs $1.20 per 100 g. A 1 kg pack for $11 costs $1.10 per 100 g, but it is only better value if the extra product will be used before it spoils.
Worksheet or calculator?
Use the Unit Price Calculator for fast comparisons or awkward pack sizes. The worksheet is useful when several products, quality notes and promotions need to be compared together.
- Comparing different units, such as one price per 100 g and another per kilogram.
- Using total pack weight when drained or usable weight is the fair comparison.
- Choosing the cheapest unit price even when the larger pack will be wasted.

Which unit should be used?
Choose the unit that makes the products genuinely comparable—often per 100 g, per kilogram, per litre, per 100 mL or per item.
Is the lowest unit price always best?
No. Quality, waste, storage, cash flow and the amount actually needed can make a slightly higher unit price the better purchase.
