Customers looking for the best deal should be conscious of the various factors that go into pricing their ride. The big ride-hailing companies use formulas that calculate the cost per mile and per minute, adding that sum to a base fare and any other fees. Those four factors each vary significantly by city—for example, in Los Angeles UberX charges no base fare at all. Taxi meters tend to charge by the mile while moving and by the minute when stopped at a light or in traffic.
The end result is that even if there is no surge pricing, the total cost differs based on the path taken to a destination or the amount of traffic. In New York, taxis tend to have higher per-minute rates, so for every "wasted" minute sitting in traffic, the cost spread between the taxi and an Uber or Lyft will increase. If you go straight to your destination 10 miles away, it will cost about 60 cents more in a taxi—not a huge difference—but if you sit in traffic for 30 minutes you'll be paying almost $6 more.
In the same way, the difference between the per-mile and per-minute rates changes how much a ride share will cost. GOBankingRates also took a look at the same trips in each city during rush hour, assuming that surge pricing would not be applied but that it would take a full hour to go the same 10 miles.
In one city—Nashville, Tennessee, Lyft is a better deal than Uber during rush hour when it was a worse deal during normal hours. In general, however, Lyft and Sidecar tend to be even more expensive during rush hour, increasing an average of $8 or $9 for Uber's $7 additional cost. But that calculation could also change if you know that you're going to be taking a highway for most of the trip—which could increase the distance traveled but decrease the time.
While the gap between providers may seem small, it can certainly add up over many trips, and ride-hailing customers tend to remain loyal to the app they use, said Bond.
"I think it's important to be aware of how the local pricing works in your city, because that has a significant impact on how much you're going to pay," said Bond. "People who tend to use ride shares use them a lot, and are often familiar with how they work and the nuances for their city."
