Group dinners go wrong when tip, tax, and unequal orders are mixed in one mental calculation. Separate the steps.
Simple even split
Per person = (Bill total + Tip) ÷ Number of people
Tip = Bill × (Tip% ÷ 100). Decide whether tip is on pre-tax or post-tax—follow local custom.
Uneven orders
Itemise what each person ordered, share common dishes evenly, then apply tip on the grand total (or proportionally). The Split Bill Calculator helps when more than two people are involved.
Run tip % scenarios in the Tip Calculator so everyone agrees before the card machine appears.
