Work out restaurant tips and split the total fairly across a group.
Quick answer: Tip Calculator
UK tipping is optional, with 10-15% common in restaurants when service charge is not already included. US restaurants commonly expect 18-22%.
Example: On a GBP 85 restaurant bill for 4 people, a 12.5% tip is GBP 10.63 total, making the split about GBP 23.91 per person.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Check whether service charge is already included before adding more. Split bills after adding tip when the group shares evenly.
