Mileage Reimbursement Calculator
If you use your personal vehicle for business purposes, you are likely entitled to reimbursement for the miles you drive. This mileage reimbursement calculator helps you determine how much money you should receive, whether your employer follows the standard IRS mileage rate or has a different company policy.
How Mileage Reimbursement Works
Reimbursement for business miles is typically calculated by multiplying the number of miles driven by a fixed rate per mile. The most common reference point is the standard mileage rate set annually by the Internal Revenue Service (IRS). Many companies adopt this rate for their reimbursement policies, while others may set a custom rate that is higher or lower.
The IRS rate is designed to cover the variable costs of operating a vehicle, such as gas, oil, tires, and maintenance, as well as the fixed costs of depreciation and insurance. It is updated yearly, usually in December, to reflect changes in the costs of owning and operating a vehicle.
How to Use the Calculator
The calculator requires three key pieces of information:
- Miles Driven: The total business miles for the trip or period you are claiming.
- Tax Year: The year in which the miles were driven, as rates can change annually.
- Reimbursement Rate: You can choose to use the IRS standard rate for the selected year, or enter a custom rate if your company has a different policy.
The calculator will then show you the applicable rate per mile and the total reimbursement amount.
Example Calculation
Suppose you drove 300 miles for business meetings in 2026, and your company uses the IRS standard rate. The 2026 IRS rate is $0.67 per mile.
- Miles Driven: 300
- Rate per Mile: $0.67
- Reimbursement = 300 miles * $0.67/mile = $201.00
You would be entitled to a reimbursement of $201.00.
Frequently Asked Questions
What if my company has a different rate? Many companies use the IRS rate for simplicity, but some may have a lower or higher rate. Always check your company's expense reimbursement policy. If they have a custom rate, select "Use Custom Rate" in the calculator and enter that value.
What documentation do I need? To get reimbursed, you typically need to submit an expense report along with a mileage log that details the date, purpose, starting location, ending location, and total miles for each business trip. Your company's policy will specify the exact requirements.
Next Steps: Creating an Expense Reimbursement Policy
For employers, having a clear, written Expense Reimbursement Policy is crucial. It sets expectations, ensures consistent treatment of all employees, and helps the company remain compliant with tax and labor laws. A good policy will clearly state the mileage reimbursement rate, the process for submitting claims, and the required documentation, such as mileage logs and receipts.
After calculating a reimbursement amount, the next step is often to formalize the claim. You can use our Expense Reimbursement Policy document to establish or review your company's guidelines, or to understand what your employer should be providing.
