The IRS standard mileage rate is a per-mile rate that taxpayers can use to calculate the deductible cost of operating a vehicle for business purposes. For 2025, the rate is $0.70 per mile. This rate covers gas, maintenance, insurance, depreciation, and most other vehicle-related costs, making it a simple alternative to tracking actual expenses.

Business mileage includes trips to meet clients, travel between work locations, trips to the bank or post office for business purposes, attending conferences, and driving to pick up supplies. It does NOT include your regular commute from home to a primary office.

No, your regular commute from home to your primary workplace is not deductible under IRS rules. However, if you work from home and drive to a client site or a secondary work location, that mileage typically qualifies as a business deduction. Consult a tax professional if you're unsure whether a trip qualifies.

It depends on your situation. The standard mileage rate is simpler and works well for most people. The actual expense method requires you to track all vehicle costs—gas, insurance, repairs, depreciation—and calculate the business-use percentage. Compare both methods or consult a tax professional to determine which saves you more.

When you tap "Track," the calculator uses your device's GPS to record your distance in real time. It uses a filtering algorithm to reduce noise and avoid counting GPS errors as movement. Once you tap "Stop," the tracked distance is automatically added to that trip entry.
