Enter the total number of stamps purchased and the total cost of the stamps into the calculator to determine the cost per stamp.

## Cost Per Stamp Formula

The following equation is used to calculate the Cost Per Stamp.

CPS = CS / #S

- Where CPS is the cost per stamp ($/stamp)
- CS is the cost of the lot of stamps ($)
- #S is the number of stamps received

To calculate the cost per stamp, simply divide the cost of the stamps by the number of stamps received.

## What is the Average Cost Per Stamp?

**The average cost of a first-class stamp is 55 cents. The average cost of a postcard stamp is 35 cents.**

## How to Calculate Cost Per Stamp?

Example:

First, determine the total cost of the lot of stamps. In this example, the total cost is $50.00.

Next, determine the number of stamps received. For this problem, the number of stamps is 400.

Finally, calculate the cost per stamp using the formula above:

CPS = CS / #S

CPS = 50 / 400

CPS = $.125/stamp
