Enter the total number of rounds and the total cost into the calculator to determine the cost per round. This calculator can also determine the cartridge cost or number of rounds if given the other variables.

Cost Per Round Formula

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

  • Where CPR is the cost per round ($/round)
  • CC is the cost of a cartridge of ammunition
  • RC is the number of rounds per cartridge

To calculate the cost per round, simply divide the cost of a cartridge by the number of rounds in the cartridge.

What is Cost Per Round?


A cost per round is a term used in ballistics to describe the cost of one round of ammunition.

The cost per round is dependent on the size, shape, and material that the round is made from. It can also depend on scarcity or uniqueness of the round.

How to Calculate Cost Per Round?

Example Problem:

The following example outlines the steps and information needed to calculate the cost per round.

First, determine the cost of one cartridge. In this case, the cartridge costs $50.00.

Next, determine the number of rounds int he cartridge. There are 100 rounds in this cartridge.

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


CPR = 50/100

CPR = $0.50 / round
