What does this tool do?
Commuting costs are usually quoted per day but budgeted per month. This calculator multiplies a daily trip cost by commute days and projects the annual total.
The Formula
Car: Round-trip miles × Cost per mile + Parking; Transit: Daily fare; Annual = Daily × Days × 52Frequently Asked Questions
Should I use a full mileage rate or fuel only?
Fuel-only shows the cash cost of driving. A full mileage rate includes insurance, depreciation and maintenance, which matters when comparing against transit.
How do I compare driving with transit?
Run both modes with the same commute days. Transit may also offer pre-tax benefits or employer subsidies that lower its effective cost.
