A Fare Calculator is a tool used to estimate the cost of a trip based on various factors such as distance, time, and type of transportation. It is commonly used in the context of taxis, rideshares, and public transit systems. Users input their starting point and destination, and the calculator provides an estimated fare, helping them budget for their travel expenses. These calculators often take into account additional variables like surge pricing, tolls, and waiting times. Many mobile apps and websites offer fare calculation features, making it easier for travelers to plan their journeys and avoid unexpected costs.
