What this means
This tool calculates the per-person cost including tip, with an option to weight the split when not everyone ordered the same.
Formula used
Per person = (total bill + tip) ÷ people. Extras adjustment adds a proportional surcharge for those who ordered more.
Worked example
A £120 bill for 4 people with a 10% tip comes to £33 each. If 1 person had extras, they pay a slightly higher share.
Common questions
What if the restaurant already added service?
If a service charge is already on the bill, include it in the total and set the tip to 0% to avoid doubling up.
How does the extras adjustment work?
People who ordered extras carry a slightly higher share of the total. The adjustment is proportional and spread across the bill rather than itemised.
Plain-English summary
Enter the bill total and number of people to get a fair split in seconds.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
