How it works
Bring both packs to the same quantity unit before comparing. For paper this may be individual sheets; for ink it may be millilitres rather than cartridges.
Choose the right inputs
The price of each pack is divided by its quantity. Four decimal places help distinguish small per-sheet differences that become important across repeated purchases.
Understand the output
A cheaper pack total does not necessarily mean better value. The smaller pack may cost less at checkout while charging more for every item it contains.
Use the result carefully
Quality, compatibility, freight and expiry are separate buying considerations. Include unavoidable purchase charges in the pack price if you want them represented in the comparison.
