How it works

2024 IRS standard mileage rate: 67 cents/mile for business. Medical and moving: 21 cents. Charitable: 14 cents. Reimbursement = miles × rate. Track actual miles using odometer or a GPS app; estimates invite audit risk. The standard rate is optional—actual expense method (fuel + depreciation + maintenance) may yield higher deductions for fuel-efficient vehicles.

Input guidance

  • Confirm date/time/unit settings before comparing outputs.
  • If a task has optional fields, run both with and without them to understand impact.
  • Save scenario variants when making practical decisions.

The formula

Reimbursement = miles driven × rate per mile. Fuel mileage = distance ÷ fuel used. Trip distance can also be summed across legs.

Worked example

A 250-mile business trip at a $0.67/mile reimbursement rate pays 250 × 0.67 = $167.50.

More examples to test

  • Quick-pass example: run default assumptions for a first estimate.
  • Refined example: update one assumption at a time to isolate impact.

How to interpret results

Use outputs as operational estimates and pair them with local constraints, business rules, or provider requirements.

When this can be inaccurate

Utilities can miss local policy details, special-case rules, and environment-specific constraints.

Frequently asked questions

How does mileage reimbursement work?+

Multiply business miles by the approved per-mile rate, which is meant to cover fuel, wear, insurance, and depreciation.

What rate should I use?+

Many follow the standard IRS business mileage rate, updated annually. Employers may set their own rate at or below it.

Do I need to log my miles?+

Yes. Keep a record of dates, distances, and purpose, since reimbursement and tax deductions require documentation.

Why are outputs slightly different from another tool?+

Different tools can use different rounding rules, default assumptions, and treatment of edge cases.

How can I improve estimate reliability?+

Use verified inputs from real records and re-run calculations after major assumption changes.
