Calculating cost per unitHow to use this price per unit calculatorSimilar tools

This versatile unit cost calculator can handle the following:

• Find price per unit weight;
• Determine price per unit volume;
• Calculate price per item;
• Evaluate price per item's weight; and
• Compute price per item's volume.

In the following article, we shall go through the fundamentals of this concept, including the formula for calculating the cost per item. We shall go through some examples to help drive the concept home.

## Calculating cost per unit

The formula for calculating cost per unit weight is:

$\text{Cost per unit weight} = \frac{\text{Total cost}}{\text{Total weight}}$

Say a 5-pound rice bag costs 4.00 at your local store. That means the cost of rice per pound is: \begin{align*} \text{Price per pound} &= \frac{\text{Total cost}}{\text{Total weight}}\\[1em] &=\frac{\4.00}{5 \text{ lbs}} = 0.8\\[1em] \implies\text{Price per pound} &=\ 0.80 \end{align*} The formula for calculating the price per unit volume is similar: $\text{Cost per unit volume} = \frac{\text{Total cost}}{\text{Total volume}}$ For example, if a gallon of milk costs3.50, what does a fluid ounce (fl oz) cost?

\begin{align*} \text{Price per fluid ounce} &= \frac{\text{Total cost}}{\text{Total volume}}\\[1em] &=\frac{\3.50}{1 \text{ US gal}}\\[1em] &=\frac{\3.50}{128 \text{ fl oz}}\\[1em] \implies\text{Price per fluid ounce} &=0.027 \equiv \0.03 \end{align*}

We bet you can already guess what the formula for calculating unit cost per item is:

$\text{Cost per item} = \frac{\text{Total cost}}{\text{Number of items}}$

Consider you are out to purchase some eggs. At your local shop, you come across an 18-count pack of eggs priced at \$4.40. Let's determine the cost per egg using the formula to calculate the cost per item:

\begin{align*} \text{Cost per egg} &= \frac{\text{Total cost}}{\text{Number of eggs}}\\[1em] &=\frac{\4.40}{18 \text{ eggs}} = 0.244\\[1em] \implies\text{Price per egg} & \equiv \0.24 \end{align*}

• Once you select the mode, enter the following details of the item under option A:

• Total cost;
• Weight, volume, or number of items, based on the chosen mode.

❗ For the last two modes, you must provide both the number of items and the weight or volume.
