This calculator helps you compare the annual costs of commuting by car versus an e-bike. You can input your daily commute distance, fuel consumption, fuel cost, and electricity cost. Additionally, you can enter annual expenses for both car and e-bike, such as insurance, maintenance, depreciation, parking fees, and financing costs. The calculator then computes the total annual cost for both car and e-bike, and shows you the annual savings and the future value of those savings after 5 years with a 10% annual interest rate.
