Imagine buying an airline ticket without knowing the full fare until reaching your destination. Or booking a hotel room online and being told that the rate would be 1.3 times higher than normal. Yes, that may seem odd—but that’s the way Uber trips used to be.

In 2016, we introduced upfront fares. Upfront fares are calculated using the expected time and distance of the trip and local traffic, as well as how many riders and nearby drivers are using Uber at that moment. Now, when fares go up due to increased demand, riders are given the actual fare before they request their ride.

With upfront fares, there’s no complicated math and no surprises—you can decide what’s best for you and your budget. Read below for pro tips on avoiding higher fares.
