Agree on the tip base
Some people tip on the pre-tax subtotal while others use the final bill. Either can be calculated; state the choice so the group understands the result.
Separate equal and unequal splits
An equal split is simple when orders are similar. Otherwise assign individual items, divide shared dishes, then allocate tax and tip using an agreed method.
Handle rounding openly
Rounding each person's amount can leave a small difference. Assign the remainder to one person or round the total first and record who covered the extra cents.
Example: four equal diners
A $120 subtotal with a 20% pre-tax tip adds $24. If tax is $9.60, the $153.60 total divided by four is $38.40 each.
What to check before you decide
- Local customs and service-charge rules vary.
- The equal-split calculator does not allocate different orders person by person.
