Price Per Unit Calculator
Find the true unit price of any pack and compare two options side by side. See which deal is actually cheaper per unit, not just per pack.
Option A
Option B
The bigger pack is not always cheaper
Suppliers price packs to look like deals. A larger pack can cost more per unit than a smaller one, especially on promotions. The only fair way to compare is the price per unit. This tool works it out for two options and tells you which is truly cheaper, plus the saving per unit.
Use it for buying and selling
On the buying side, it stops you overpaying for stock and supplies. On the selling side, it helps you set pack prices that look attractive while protecting your margin. Either way, the unit price is the number that cuts through clever packaging and promo wording.
How to use it
Enter the total price and quantity for each option. The tool shows the per-unit price of both and names the better deal with the exact saving. Quantity can be units, grams, litres, or any measure, as long as you use the same one for both. To turn a unit cost into a sell price, use the Markup Calculator.
Frequently Asked Questions
How do you calculate price per unit?
Divide the total price by the number of units. Compare the two results to see which pack is cheaper per unit.
Why compare per unit instead of per pack?
Because packs come in different sizes. Per unit is the only fair comparison when quantities differ.
Can I compare weights or volumes?
Yes. Use the same measure for both options, such as grams or litres, and the comparison holds.
