Does an existing service charge mean you should add another tip?
Read the bill before making an additional calculation. A service charge and a voluntary extra tip are separate entries, and the calculator cannot decide whether another payment is appropriate.
Tip & split bill →Identify charges already included
A service charge may appear as a percentage line or already be included in the total. Whether it is mandatory, adjustable or taxed depends on local rules and the venue’s terms. The label alone is not enough to establish those conditions. Treat the calculator as an arithmetic aid after you have established what has already been charged.
See how double counting happens
Suppose the purchase subtotal is 100 and an existing service charge of 10 makes the bill 110. If no additional tip is chosen, entering 110 with a 0% tip gives 55 each for two people. Choosing a separate voluntary 5 makes the total 115, or 57.50 each. Entering 10% on the 110 bill instead adds another 11; it does not merely acknowledge the original charge of 10.
Distinguish a percentage from a fixed extra amount
The calculator applies its tip percentage to the entire entered amount. If you intend to use a before-tax subtotal or add a fixed amount, work that out explicitly rather than inadvertently tipping on an existing charge. This article does not prescribe whether a tip should be given. It explains how to reconcile the final payment and avoid treating an already-paid amount as a new addition.
