How the Tip and Bill Split Calculator works
Additional tip = max(0,bill−included service charge) × tip rate; total = bill + additional tip; per-person = total/people. Inputs stay in this browser, and the result table exposes conversions and assumptions for independent checking.
Interpret the result
The service charge is shown separately and not silently treated as an additional tip.
Check the assumptions
Customs, wages, taxes and service-charge treatment vary by location and venue; review the bill and follow local practice.
Local calculation
