Method and background
How this is calculated
The tip goes on the bill and the total divides by the number of people. Rounding each share up is the sociable option and it slightly increases the tip, which the tool shows separately rather than hiding in the total.
per_person = bill * (1 + tip) / people- B
- Bill (currency)
- n
- Number of people
