Reimbursement

Show the math
The standard mileage method multiplies the miles you drove by the IRS rate for that purpose:
reimbursement = miles × rate per mile
The IRS changed its 2026 rates mid-year. From July 1 – December 31, 2026: 76¢ a mile for business, 23.5¢ for medical or military moving (moving only for certain active-duty members of the Armed Forces), and 14¢ for charity. From January 1 – June 30, 2026: 72.5¢, 20.5¢, and 14¢. The rate is meant to cover fuel, wear, insurance and depreciation.
The IRS sets these rates and can change them during the year; employers may reimburse at a different rate. Everything is calculated in your browser.
What this does
A mileage reimbursement calculator works out what you are owed using the 2026 IRS standard rates for business, medical, or charity driving, or your own custom rate.
How to use it
- Enter the miles driven.
- Choose the purpose or rate.
- Or enter a custom rate.
- Read the reimbursement.
How it works
The standard method multiplies miles by a per-mile rate covering fuel, wear, insurance, and depreciation. The IRS raised its 2026 rates on July 1: $0.76 business, $0.235 medical, $0.14 charity (January–June: $0.725, $0.205, $0.14).
reimbursement = miles × rate
Understanding your result
The standard per-mile rate already bundles fuel, wear, insurance, and depreciation, so do not also claim those costs separately or you double-count. Use the rate that matches the purpose of the trip, since business, medical, and charity rates differ sharply, and keep a contemporaneous mileage log, because that record is what a claim or an audit relies on.
Example
300 business miles at the July–December 2026 rate of $0.76 is $228 reimbursed.
