Tarifa Hoje is an application designed to help drivers and motoboys check whether the value offered by transport and delivery applications is fair. The application takes into account several parameters, such as fuel price, vehicle autonomy, daily rate (if vehicle rented), taxes, maintenance cost, depreciation, insurance and the user's monthly withdrawal expectation. Based on this information, Tarifa Hoje provides an estimate of the amount that should be charged, allowing drivers and motoboys to carry out a comparative analysis and decide whether the amount offered is fair or not. Furthermore, it is possible to use accumulated data from a working day, week or month, to assess whether the period's earnings are compatible with the user's expectations. With this tool, drivers and motoboys can make better decisions and protect their profits.
