Mileage Calculator

About the Mileage Calculator

A mileage calculator tracks vehicle trips for IRS tax deductions, employer reimbursement claims, fleet management, and vehicle maintenance scheduling. Accurately tracking business mileage is one of the simplest and highest-value tax deductions available to self-employed individuals and employees who use personal vehicles for work — at the 2024 IRS standard mileage rate of 67 cents per mile, driving 15,000 business miles per year generates a $10,050 deduction that saves approximately $2,200-3,000 in federal income tax at typical rates. Our free mileage calculator logs individual trips (date, destination, purpose, odometer readings), calculates reimbursement amounts at any specified rate, tracks total annual mileage by category (business, medical, charitable), generates summary reports for tax filing, and estimates upcoming maintenance intervals based on current mileage.

How It Works

IRS standard mileage rates for 2024 (adjusted annually): Business use: $0.67 per mile. Medical and military moving: $0.21 per mile. Charitable organisations: $0.14 per mile (set by statute). Tax deduction = business miles driven × $0.67. Example: 12,000 business miles × $0.67 = $8,040 deduction. At 22% marginal rate: tax savings = $8,040 × 0.22 = $1,769. Alternatively, you can deduct actual vehicle expenses (fuel, insurance, depreciation, maintenance) multiplied by the business-use percentage — the calculator compares both methods to identify the larger deduction. The IRS requires contemporaneous records: date, destination, business purpose, and miles driven for each trip.

Tips & Best Practices

• ✓Contemporaneous records are essential: the IRS requires you to record trips at the time of travel, not reconstructed at year-end from memory. Courts have disallowed deductions from reconstructed logs.
• ✓Standard mileage vs actual expenses: for the first year a car is used for business, you can choose either method. If you choose actual expenses in year 1, you generally cannot switch to standard mileage in later years for that vehicle.
• ✓Commuting is not deductible: driving from your home to your regular office is personal commuting. Trips between two work locations, from home to a client site if home is your principal place of business, or to a temporary work location are deductible.
• ✓Charitable mileage: driving for a qualifying charitable organisation is deductible at $0.14/mile. Keep the same records as for business mileage. This rate is set by statute and rarely changes.
• ✓Medical mileage: travel to doctors, dentists, hospitals, and other medical providers is deductible as a medical expense at $0.21/mile — but only to the extent total medical expenses exceed 7.5% of AGI.
• ✓GPS-based mileage apps (MileIQ, Everlance, TripLog) automatically track trips via GPS, classify them as business or personal with one swipe, and export IRS-compliant reports — eliminating manual logging effort.
• ✓Vehicle tax basis: if you use your vehicle for business, you must reduce the tax basis by the depreciation allowable (whether or not you claim it) when you eventually sell. Proper tracking from the start prevents complications later.
• ✓Employer reimbursement: if your employer reimburses at or below the IRS standard rate, the reimbursement is tax-free income. If employer reimburses above the standard rate, the excess is taxable compensation.
