Enter the daily rate and the number of days deployed into the calculator to determine the total per diem. This calculator helps to estimate the total allowance for expenses incurred while on deployment.

Deployment Per Diem Formula

The following formula is used to calculate the total per diem for deployment.

TPD = DR * DD

Variables:

  • TPD is the total per diem (USD)
  • DR is the daily rate (USD per day)
  • DD is the number of days deployed

To calculate the total per diem, multiply the daily rate by the number of days deployed.

What is Deployment Per Diem?

Deployment per diem is a daily allowance given to employees or military personnel to cover expenses while they are on deployment away from their usual place of work. This allowance is meant to cover lodging, meals, and incidental expenses that occur as a result of being deployed. The rate can vary depending on the location and duration of the deployment, as well as the policies of the organization.

How to Calculate Deployment Per Diem?

The following steps outline how to calculate the Deployment Per Diem.


  1. First, determine the daily rate (DR) in USD per day.
  2. Next, determine the number of days deployed (DD).
  3. Next, gather the formula from above = TPD = DR * DD.
  4. Finally, calculate the Total Per Diem (TPD) in USD.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
