Our tip splitter makes it easy to divide a restaurant bill fairly between any number of diners. Enter the total bill amount, choose a tip percentage (or enter a custom amount), and specify how many people are sharing. The calculator shows the tip amount, the total bill including tip, and each person's share. You can also adjust for unequal splits if some diners had more expensive meals. In the UK, a tip of 10–12.5% is customary at sit-down restaurants, though many restaurants now add a service charge automatically — always check your bill before adding an additional tip.
