Split a restaurant bill with tip across multiple diners and show each person’s fair share.
Calculations
Given bill amount B, tip percentage T, and party size N:
- Tip =
(T / 100) × B - Total =
B + tip - Per person =
total ÷ N
All values use standard floating-point arithmetic; round for cash payments according to local coinage.
When to use it
End-of-meal math without mental arithmetic, shared delivery orders, or teaching how gratuity compounds before division.
Limitations
Does not handle uneven splits (one person ordered more), tax-included versus tax-added menus, or currency conversion. Tip percentage is uniform — custom per-guest tips require manual adjustment.
