How it's calculated
Car costs = fuel (miles ÷ MPG × gas price) + other costs per mile. Real hourly pay = (pay − car costs) ÷ hours. The tax set-aside is self-employment tax (15.3% on 92.35%) on your pay minus the IRS standard mileage deduction ($0.76 per mile from July 1, 2026). Income tax isn't included, and this isn't tax advice.
