1. What is Per Diem?

Per Diem refers to a daily allowance for expenses, typically used for business travel, military personnel, or other situations where individuals need to cover daily costs while away from home.

2. How Does the Calculator Work?

The calculator uses the simple Per Diem formula:

Where:

• \( Rate \) — Daily allowance rate in USD
• \( Days \) — Number of days the allowance covers

Explanation: The calculation multiplies the daily rate by the number of days to determine the total allowance.

3. Importance of Per Diem Calculation
