Breakdown
When a group dines together, dividing the combined total including tip keeps things simple and avoids awkward math at the table. Round up to the nearest dollar per person if you want to leave a little extra.
Suppose the bill is $80, you want to tip 18%, and you are splitting it between 2 people.
Result: The tip is $14.40, the total comes to $94.40, and each of the 2 people pays $47.20.
