Frequently asked questions
- Does this include all car costs?
- No — fuel is typically only about 20–25% of total driving costs. The IRS mileage rate ($0.67/mi in 2024) accounts for depreciation, insurance, maintenance and fuel combined.
- How much could I save by working from home?
- Enter your current commute stats to see the annual cost, then compare that to a reduced number of office days. Every day working remotely saves a proportional fraction of your annual commute cost.
