Fare calculators are online tools that help users estimate the cost of transportation services, such as taxis, rideshares, or public transit. By inputting details like the starting point, destination, and sometimes the time of day, these calculators provide an approximate fare based on distance, time, and local rates. Many fare calculators also consider additional factors, such as surge pricing during peak hours or discounts for specific groups. They are commonly used by travelers and commuters to budget their transportation expenses and make informed decisions about their travel options, including services like Uber or Lyft.
