There are many home care options, and knowing the differences between the different types of services and service providers can aid you in making the right decision.
The post the fare schedule for each city on their website. e.g. here is Lyft Boston $2.25 + $1.50 per mile and $.30 per minute. It's hard to say what a typical ride is. In my experience Lyft is always cheaper than a Boston cab. UberX is sometimes cheaper as long as surge pricing is not turned on.
While both companies offer a range of more expensive, premium rides in luxury SUVs and limos, a basic ride will cost you about the same in Lyft as it will in UberX. While costs vary city-to-city for Uber and Lyft, rides are generally $1 to start, $1.50/mile, and $0.25/min.t high-demand times and locations, the cost of a Lyft or Uber ride can significantly increase. For Lyft,  Prime Time  can increase the cost of a ride by 25 to 200%.
