Frequently Asked Questions
Common questions about the free online unit price calculator.
Type one product per line as name, price, quantity, then press Compare to see the price per
unit of each one.
Pack prices hide different sizes. Unit price divides the cost by the quantity, so a large
pack and a small pack can be judged fairly.
Enter the amount in the pack, such as grams, millilitres or item count. Keep every product in
the same unit for a fair result.
You can compare up to twenty products at the same time, and the table lists them all with
their unit price.
Yes. Choose 10, 100 or 1000 in the compare per menu and every product is scaled to that base
size.
The tool still names the first one as best value and reports no price difference between the
best and worst options.
That line is skipped, because dividing the price by a zero quantity is not a valid unit
price.
Enter every quantity in the same unit, for example all in grams, and the comparison stays
exact.
No. Everything is parsed and calculated locally in your browser, so your prices never leave
your device.
