About
Work out which pack, bottle, or bundle gives you more value for the money.
What this calculator helps with
The Unit Price Calculator compares two offers and tells you how much each one costs per unit. It also highlights which option is the better deal, how much you save on each unit, and the break-even price where both offers would cost the same per unit.
How to compare offers fairly
Enter the total price and quantity for both offers using the same unit of measure. For example, compare 500 g against 1,000 g, 12 cans against 24 cans, or 250 ml against 1,000 ml. If the units are mixed, convert them first so the result stays accurate.
Why the break-even price matters
Break-even prices show what each offer would need to cost in order to match the other option on a per-unit basis. This is useful when you expect a sale, negotiate supplier prices, or want to know the highest price you should pay before the value advantage disappears.
Common use cases
- Comparing grocery pack sizes in a store or online cart.
- Checking whether bulk household supplies are actually cheaper.
- Reviewing vendor quotes for office, cafe, or retail purchasing.
- Choosing between subscription, bundle, or refill options.
Important limitations
This calculator focuses on pure price-per-unit comparison. It does not judge quality differences, expiration dates, shipping costs, taxes, or whether a larger package creates waste. Use it as a pricing guide, then combine the result with your real-world buying needs.
