Data Source and Methodology
All calculations are based on the official IRS reimbursement rates for business mileage. For more details, refer to the IRS website. All calculations are strictly based on the formulas and data provided by this source.
The Formula Explained
The mileage reimbursement is calculated using the formula:
Reimbursement = (End Mileage - Start Mileage) × Rate per Mile
Glossary of Terms
- Start Mileage: The odometer reading at the start of the trip.
- End Mileage: The odometer reading at the end of the trip.
- Rate per Mile: The reimbursement rate per mile as set by the IRS.
- Reimbursement Amount: The total reimbursement based on the mileage and rate.
How It Works: A Step-by-Step Example
Imagine you drove from your office to a client meeting. Your odometer read 1,000 miles at the start and 1,050 miles at the end. If the IRS rate is $0.58 per mile, your reimbursement would be calculated as follows:
Reimbursement = (1,050 - 1,000) × $0.58 = $29.00
