Why Uber is losing so much money? The biggest part of the problem is that Uber is a relative small fish in the market and is not getting nearly enough customers. According to analyst reports, as of August 2015, Didi Kuaidi completed seven million rides as opposed to Uber's one million.
Because Uber hasnât arrived in Las Vegas, thereâs no price list since every city has different rates and the company has three or four levels of service.

In Denver, the UberX rate is a $2.14 base fare and 19 cents a minute.In Phoenix, itâs $2.94 plus 25 cents a minute and in Los Angeles, $1.91 and 29 cents a minute. But thereâs a catch that local Uber critics have pounced on.t costs $3.30 for the initial activation of the taxi meter, plus $2.60 a mile after that and $30 an hour âwait time,â the time that vehicle is stopped in traffic or traveling under 12 mph.
