Unit Price Calculator
Compare two products by price per unit and see the saving.
Quick answer
- Formula: Unit price = Price ÷ Quantity; Saving% = (higher − lower) ÷ higher × 100
- Worked example — Product 1 unit price: $0.5000 (full example below).
Unit Price Calculator
| Product 1 unit price | $0.5000 |
| Product 2 unit price | $0.4500 |
| Better value | Product 2 is the better value |
| Saving vs the other product | 10.00% |
Product 1 costs $0.50 per unit and product 2 $0.45 per unit — product 2 is better value, a 10% saving per unit.
Bigger packs are not always better value. Enter the price and quantity of two products — same units for both, such as ounces or grams — and this calculator compares their unit prices and tells you which is better and by what percentage.
Quantities must be in the same unit for a fair comparison; most supermarket shelf labels already print a unit price you can check against.

Frequently asked questions
How is the saving percentage calculated?
As the difference between the two unit prices divided by the higher unit price. Dropping from $0.50 to $0.45 per unit saves $0.05, which is 10% of $0.50.
Is the bigger pack always the better deal?
No — promotions on smaller packs regularly undercut bulk pricing per unit, and a large pack you cannot finish before it expires is no saving at all. The unit price tells the truth.
