“Per diem” is a Latin phrase meaning “per day” or “for each day.” In everyday business use, it most often refers to a fixed daily allowance that an employer provides to cover an employee’s expenses while traveling for work, such as meals, lodging, and small incidental costs. The phrase can also describe work that is paid or scheduled by the day.
What does per diem mean?
At its root, per diem simply means “by the day.” How it is applied depends on context. In travel and expense policies, it is a set amount of money given for each day away on business. In staffing, it describes a worker hired on a day-by-day basis. In both cases, the “per day” idea is central.
What does a per diem allowance cover?
When used as a travel allowance, a per diem typically covers the routine costs of being away from home for work. Employers may provide a single combined daily rate or separate amounts for different categories.
- Meals during the workday or trip.
- Lodging, such as a hotel stay.
- Incidental expenses, like tips or small fees.
A per diem may cover all of these or only some, depending on the employer’s policy. Some organizations pay only for meals and incidentals while booking lodging separately.
Does per diem require receipts?
One of the main advantages of per diem is simplicity. Because the daily rate is fixed, employees often do not need to save receipts and file detailed expense reports for every meal or purchase. The employer pays the standard amount regardless of exactly how much was spent, which reduces paperwork for both sides. This is a key reason many companies and agencies use per diem systems.
What is a per diem worker?
Beyond travel, “per diem” describes a type of employment. A per diem worker is paid by the day and scheduled as needed rather than on a fixed full-time basis. This arrangement is common in healthcare, where a per diem nurse, for example, picks up shifts as demand requires. It offers flexibility for both the employer and the worker.
- “The conference offers a $75 per diem for meals.”
- “She works per diem at two local hospitals.”
Where is per diem used?
Per diem appears across business, government, healthcare, and legal settings. Employers use it to manage travel budgets predictably, agencies set standard per diem rates for official travel, and staffing systems use it to describe flexible, day-based work. In legal contexts it can also refer to an amount charged or accruing each day.
In short, per diem means “per day.” Whether it is a daily travel allowance that simplifies expenses or a form of day-by-day employment, the phrase always comes back to that same simple Latin idea: for each day.
