IRS Mileage Reimbursement Calculator
The IRS standard mileage rate lets you compute the deductible cost of operating a vehicle, or reimburse an employee, at a flat cents-per-mile figure instead of tracking actual costs. This calculator multiplies your miles by the rate to give the reimbursement or deduction. Because the IRS updates the rates and sets a different figure for business, medical/moving and charitable use, the rate is an editable input: enter the cents-per-mile figure from the IRS standard mileage rates page and your miles to get the amount.
Mileage reimbursement formula
Rate (dollars/mile) = rate in cents / 100 Amount = miles driven x rate in dollars per mile
Use the business rate for business driving, or the separate medical/moving and charitable rates for those purposes.
Worked example
1,200 business miles at 70 cents per mile: rate = 0.70 per mile, amount = 1,200 x 0.70 = 840.00.
IRS mileage: frequently asked questions
What is the IRS standard mileage rate?
The IRS standard mileage rate is a cents-per-mile figure you can use to compute the deductible costs of operating a vehicle for business, charitable, medical or moving purposes, instead of tracking actual costs. The IRS sets a separate rate for each purpose and updates them, usually annually, in a notice.
Why is the rate an editable input?
The standard mileage rates change, typically each year and sometimes mid-year, and differ by purpose (business, medical/moving, charitable). To avoid showing a stale figure, this calculator takes the rate in cents per mile as an editable input. Look up the current rate on the IRS standard mileage rates page before relying on the result.
Which mileage purposes qualify?
Business use of your car is deductible for self-employed taxpayers and certain others. Medical and moving mileage are deductible in limited circumstances (moving mostly for active-duty military). Charitable mileage is deductible when driving in service of a qualified organisation; its rate is set by statute and is lower. Pick the rate that matches your purpose.
Can my employer reimburse me at the IRS rate?
Yes. Employers commonly reimburse employees for business driving at the IRS business standard mileage rate under an accountable plan, in which case the reimbursement is not taxable to the employee. Reimbursement above the IRS rate, or without proper records, may be treated as taxable wages.
