How is a per diem rate calculated for an annual expense of $1500 in July?

The per diem rate is calculated by determining the daily cost of an annual expense, which is typically done by dividing the total annual expense by the number of days in a year. In this case, the annual expense is $1500. Dividing this amount by 365 days gives you the daily cost, which accurately reflects the cost of the expense on a daily basis.

Calculating $1500 divided by 365 results in approximately $4.11, which allows for a consistent and precise understanding of the expense incurred each day throughout the year. This method is widely accepted for various financial calculations since it evenly distributes the total cost over the entire year.

Using 30 days or 31 days to determine a daily rate does not represent the total annual allocation accurately, as it would only reflect a portion of the year’s costs instead of the entire year. Similarly, dividing by 12 months does not account for the varying lengths of each month, which is also less reflective of a true daily per diem. Thus, dividing by 365 provides the most accurate daily figure for budgeting or estimating expenses over the course of the year.
