How to use it

Using the mileage reimbursement calculator

  1. 01

    Log your miles

    Record start and end odometer readings per trip, with purpose and date; contemporaneous logs survive audits.

  2. 02

    Confirm the governing rate

    Employers may pay the IRS rate or their own; self-employed filers deducting mileage should use the current IRS figure.

  3. 03

    Multiply and submit

    Enter miles and rate here, then attach the result to your expense system with supporting notes.

Good to know

What the rate is meant to cover

Per-mile rates bundle fuel, depreciation, insurance and maintenance into one number; why it exceeds raw fuel cost several-fold. Accepting a lower company rate means subsidizing your employer’s fleet costs personally.

Actual-expense alternative

Self-employed taxpayers can instead deduct genuine vehicle expenses proportional to business use. High-cost vehicles sometimes come out ahead; most drivers find the standard-rate path simpler and comparable.

Documentation is everything

Reimbursements and deductions both rest on adequate records: date, destination, business purpose, odometer. Reconstructed logs are precisely what examiners disallow.

How it's calculated

The math behind this calculator

Reimbursement = miles driven × rate per mile

Straight multiplication: qualifying miles times the applicable per-mile rate. The editable rate defaults to a recent IRS-style business figure, but agencies revise it annually (and sometimes mid-year), so verify the rate that governs your claim.

Assumptions & limitations

  • All entered miles qualify as business travel under your policy.
  • Commuting from home to a regular workplace usually does not qualify.
  • Rate defaults reflect a recent IRS-style figure; confirm the current official rate.

Worked example

Driving 250 business miles at a $0.70 per-mile rate earns a $175.00 reimbursement; log the odometer readings for each trip.

FAQ

Frequently asked questions

What is the current IRS rate?
It changes; often each January, occasionally mid-year as fuel prices did in 2022. Search for the latest IRS standard mileage notice and enter it here; the field is editable for exactly that reason.
Must my employer reimburse at all?
Federal US law does not require it, though California and a few other states effectively do. Company policy governs elsewhere.
Do commuting miles count?
Generally no; home-to-main-office travel is personal. Errands between client sites during the workday do qualify.
