Note: The official 2025 rate is usually released in late 2024. The default value reflects the 2024 baseline ($0.67).

Understanding GSA Mileage Rates for 2025
Federal employees who use their privately owned vehicles (POV) for official government business are reimbursed at a specific rate per mile set by the General Services Administration (GSA). This rate is designed to cover the costs associated with operating the vehicle, including fuel, maintenance, insurance, and depreciation.
Anticipating the 2025 Rate Change
The GSA typically reviews and adjusts the mileage reimbursement rate annually. The official rate for a given year is usually announced towards the end of the preceding year (e.g., the 2025 rate is expected to be announced in late 2024). While the exact 2025 rate is not yet known, it is often influenced by fluctuating economic factors such as average gasoline prices and vehicle costs over the previous year. For reference, the standard POV rate for 2024 was set at $0.67 per mile.
How to Use This Calculator
This calculator helps you estimate your reimbursement based on projected or known rates. To use it:
Total Miles Driven: Enter the total number of miles you drove specifically for official business purposes.
Projected 2025 GSA Rate: The calculator defaults to the 2024 baseline rate ($0.67). You can adjust this field if a new official rate has been announced or to test different scenarios.
The tool will multiply your miles driven by the rate to provide an estimated total dollar amount for reimbursement.
Example Calculation
If a federal employee drives their personal car 450 miles for a temporary duty assignment, and the GSA rate is projected to slightly increase to $0.685 per mile for 2025, the calculation would be:
450 miles x $0.685/mile = $308.25
This employee would submit a voucher for a $308.25 reimbursement for their travel expenses.
