tip calculator

Even with a tip calculator, a few mistakes can lead to incorrect results.

Entering the wrong bill amount is one of the most obvious problems. Choosing the wrong tip percentage can have a similar effect. Another common issue is dividing the bill by the wrong number of people, particularly when some diners arrive late or leave early.

It is also worth checking whether the restaurant has already included a service charge. Adding a separate tip without noticing an existing charge can produce a different total than expected.
