You are not "supposed" to tip in cash, as Lyft is designed to be a completely cashless platform, but cash is always appreciated by drivers. Most passengers prefer to tip through the Lyft app after the ride is completed; the app provides preset options like 15%, 20%, or 25%, or you can enter a custom amount. One major benefit of tipping through the app is that it keeps a digital record of your expenses, which is helpful for business travelers. However, some passengers prefer cash because it ensures the driver receives the money immediately and in full, without any potential digital processing lag. Regardless of the method, tipping is socially expected in the U.S. for good service, typically ranging from $2 to $5 for a short trip or 15-20% for longer journeys. Lyft drivers keep 100% of their tips, whether digital or physical. If a driver goes above and beyond—like helping with heavy luggage or navigating a difficult detour—a small cash tip on top of the app tip is a great way to show extra gratitude.
