🛒 find the real better deal

Unit Price Comparator

Compare price-per-unit across different package sizes to see which one is actually cheaper. Nothing leaves your browser.

How it works

Each option's unit price is just its price divided by its quantity, recalculated on every keystroke; the row with the lowest resulting unit price is automatically outlined as the best deal, and a quantity of zero shows a dash instead of a divide-by-zero result.

FAQ

What happens if I leave the quantity field at zero?
The unit price for that item shows as a dash instead of a number — dividing by zero is treated as an undefined price rather than infinity or an error, and that item is never marked as the best deal.
Do I need to convert units so they match before comparing?
Yes — the tool just divides price by the quantity you type, so 12oz vs. 1lb won't compare correctly unless you convert one of them to match the other's unit first.
