Mileage Calculator — Frequently Asked Questions
Q1 What is the IRS standard mileage rate and how is it used? ▾
The IRS standard mileage rate is the official per-mile tax deduction rate for business, charitable, medical, and moving travel in lieu of tracking actual vehicle expenses.
Q2 How do you calculate your vehicle's fuel cost per mile? ▾
Divide the price per gallon of gas by your vehicle's miles per gallon (MPG): Cost per mile = Gas Price / MPG. For example, $3.50 per gallon at 25 MPG is $0.14 per mile.
Q3 What records do you need to keep for a business mileage tax deduction? ▾
You must record date of trip, starting and destination locations, purpose of trip, and total miles driven using a mileage logbook or GPS tracking app.
Q4 How can driving habits improve vehicle fuel mileage? ▾
Smooth acceleration, maintaining steady highway speeds with cruise control, keeping tires properly inflated, and removing unnecessary cargo weight can improve fuel economy by 10%–20%.
