A Dot Per Diem Calculator helps determine the daily allowance for travel-related expenses such as meals, incidental expenses, and lodging. The calculation follows the Department of Transportation (DOT) or General Services Administration (GSA) per diem rates, ensuring that travelers, particularly truck drivers and business professionals, receive appropriate reimbursements while staying within federal guidelines.
This tool is useful for individuals and businesses managing travel expenses, allowing them to estimate daily allowances accurately based on location-specific rates.

- Travel Days: The number of days in travel status
- Lodging Rate: The maximum allowable lodging rate for the location
- Overnight Stays: The number of nights requiring accommodation
This formula ensures that all essential travel costs are covered, providing clarity for expense planning and reimbursement claims.
