How the bill is split
- The tip or service charge is added to the bill to give the total to pay.
- Anyone paying a set share is taken off first. A set amount is exactly what that person pays; a percentage is a share of the total, including the tip.
- Whatever is left is split evenly between everyone else.
Money is worked out to the penny. When the bill doesn't divide exactly, a few people pay one penny more, so the shares always add up to the full total and nothing is left over for the last person to cover.
Worked example
Five people have a meal that comes to £120.00, with a 12.5% service charge on top. Nigel only had a main course and wants to pay £25.00, and Mum is treating everyone to half the bill.
- The service charge is £15.00, so the total to pay is £135.00.
- Nigel pays his set amount of £25.00, and Mum pays 50% of the total: £67.50.
- That leaves £42.50 for the other 3 people: £14.17, £14.17, £14.16.

Frequently asked questions
Does someone paying a set amount also pay towards the tip?
A set amount is exactly what that person pays, so include their share of the tip in it if you want them to contribute. A percentage is always a share of the total including the tip.
Should I add a tip if there is already a service charge?
No. Many UK restaurants add a discretionary service charge, often 12.5%, to the bill. If it is already included in your bill total, leave the tip field blank so it isn't counted twice.
Why do some people pay a penny more?
Bills don't always divide exactly. For example, £100 between three people is £33.333… each. Rather than leave a penny unpaid, one person pays £33.34 and the others £33.33, so the shares add up to exactly £100.
What if someone only had a drink?
Add them as a person with a set amount equal to what they had. Everyone else will split the rest of the bill evenly.
Why can't the set shares add up to more than the bill?
Set amounts and percentages are taken from the total to pay, so together they can't be more than the total. For example, 50% and 60% would come to 110% of the bill. The calculator will tell you if this happens so you can adjust the shares.
