Good to Know

The rate presets are a commonly-cited convenience starting point, not this year's actual published IRS rate — always verify the current standard mileage rate before using this for an actual tax return or reimbursement request.

How This Calculator Works

The standard mileage rate method estimates a tax deduction or reimbursement by multiplying miles driven by a set per-mile rate — an alternative to tracking and deducting actual vehicle expenses like gas, maintenance, and depreciation. Enter the miles driven and a rate per mile to see the total deduction or reimbursement amount.

The IRS publishes a different standard mileage rate for each of three purposes — business, medical or moving, and charitable driving — and updates them at least annually (sometimes mid-year). The rate presets here are a commonly-cited convenience starting point, not this year’s actual published rate — always check the IRS’s current published rate (linked above) before using this for an actual tax return or reimbursement request.

The Formula

Deduction/Reimbursement=Miles Driven×Rate Per Mile\text{Deduction/Reimbursement} = \vA{\text{Miles Driven}} \times \vB{\text{Rate Per Mile}}

Worked Example

Driving 1,000 miles for business at a rate of $0.67 per mile:

  1. Deduction/reimbursement: 1,000×$0.67=$670\vA{1{,}000} \times \vB{\$0.67} = \$670.

Frequently Asked Questions

What is the standard mileage rate method?

It's a simplified way to deduct vehicle costs for business, medical/moving, or charitable driving — multiplying miles driven by a set per-mile rate — as an alternative to tracking and deducting actual expenses (gas, maintenance, depreciation, insurance).

Why does the rate differ by purpose?

The IRS publishes three separate standard mileage rates — business, medical or moving, and charitable — each reflecting different underlying cost assumptions and, for charitable driving, a rate set by statute rather than IRS calculation.

How often does the rate change?

The IRS typically updates its standard mileage rates once a year, though it has occasionally adjusted them mid-year in response to fuel price changes. Always check the current published rate rather than relying on last year's figure.
