This app is a personal commute cost calculator for everyday commuters. It helps you compare monthly and annual spending across transit, ride-hailing, driving, and e-bike options, and separates direct expenses from hidden wear and depreciation—so you can inform travel choices and commute budget planning. - Multi-mode cost comparison: Under a single commute scenario, compare per-trip, daily, monthly, and annual costs across travel modes. - Explicit vs. hidden costs: Separate direct spending (fares, fuel, parking, etc.) from indirect costs that are easy to overlook (depreciation, insurance, maintenance, battery wear, and more). - Overall best-pick guidance: Suggest a relatively better option by weighing cost, comfort, and fit for your situation. - Asset commute wear: Track depreciation and usage wear for commute assets such as cars and e-bikes to assess long-term ownership cost. - Periodic review & reports: Summarize commute spending over a period, with monthly logging and readable report output. - Scenario & parameter management: Use templates and parameter settings to match different commute habits, with local backup and restore. All results are estimates based on user-entered parameters and built-in models, for reference only. They are not financial or travel advice; actual costs should be verified against your bills.
