Tip Calculator
Split the bill and tip fairly in seconds. Tip = bill × tip rate. Total = bill + tip. Per-person amounts divide by at least one person. How it works Etiquette guides say pre-tax, but most people tip on the total. The difference is small; choose one and don't stress about it. Validation: Allows negative bill amounts (e.g. -10 gives negative totals); Split between 0 seems to be treated as 1 (Total per person equals Total with tip); Empty bill amount yields $0.00 for all outputs.
