What if the two products use different units, like grams vs ounces?

Convert both quantities to the same unit before entering them — the calculator just divides price by the quantity number you enter, so comparing 500g to 16oz directly would give a meaningless result unless both are in grams or both in ounces.

Does the lowest unit price always mean the best deal?

Usually, but not always — it tells you which product costs less per unit of quantity, ignoring factors like quality, expiration date, or whether you'll actually use the larger quantity before it goes to waste. Use it as a price comparison, not the whole buying decision.

Unit Price Calculator

Compare two products by price-per-unit to find the better deal.

How this is calculated

Unit price = Price ÷ Quantity; the lower unit price is the better deal

Assumptions used in this calculation

Same unit required: Both products' quantities must be entered in the same unit of measure — the calculator doesn't convert between units (e.g. grams to ounces).

About this calculator
