What is a Mileage Calculator?

A Mileage Calculator computes the distance cost for driving, which is useful for business expense reimbursement, tax deduction calculations, and trip budgeting. The IRS sets standard mileage rates annually — for 2026, the rate is approximately 70 cents per mile (reflecting elevated fuel and vehicle maintenance costs). This calculator handles both the standard IRS deduction method (× miles driven) and the actual expense method (tracking all vehicle costs), helping you determine which saves more on your taxes or what to charge for business driving.

How Does It Work?

Enter your trip distance (or odometer start/end readings), select your vehicle type (personal car, truck, motorcycle), and optionally your actual vehicle expenses (fuel, insurance, maintenance, depreciation, loan interest). The calculator computes: Reimbursement = Miles × IRS Rate; Cost per Mile = Total Annual Vehicle Expenses ÷ Annual Miles; and compares the standard mileage method vs. actual expense method for tax deductions.

Formula

Standard Mileage = Miles Driven × IRS Standard Rate\n(for 2026: ~$0.70/mile for business)\n\nCost per Mile = Annual Vehicle Expenses ÷ Annual Miles\n\nActual Expense Method:\nDeductible = (Total Vehicle Expenses × Business Miles%) + Parking + Tolls\n\nTrip Fuel Cost = (Distance ÷ MPG) × Fuel Price per Gallon\n\nTotal Trip Cost = Fuel Cost + (Distance × Maintenance per Mile) + (Distance × Depreciation per Mile)

Frequently Asked Questions about Mileage Calculator

What's the current IRS mileage rate?

The IRS standard mileage rate for business driving is typically 65.5-70 cents per mile. As of 2026, it's approximately 70 cents per mile. The rate changes annually based on gas prices and vehicle costs. Check IRS.gov for the current rate.

Should I use standard mileage or actual expenses?

Calculate both. Standard mileage is simpler (just track miles). Actual expenses (fuel, repairs, insurance, depreciation) can be higher if you drive a newer, expensive vehicle with high costs. Once you choose the actual expense method for a vehicle, you generally can't switch to standard mileage in later years.
