How This Calculator Works
Enter the bill amount and the service charge percentage. The calculator multiplies the bill by the percentage to find the service charge, then adds it for the total. A service charge is added by the business, unlike a tip, which is left at the customer's discretion.
The Formula
Percentage Add-On
Rate is the tax or tip percentage applied to the amount
Worked Example
A $200 bill with an 18% service charge adds $36, for a total of $236. Because the charge is already on the bill, an additional tip on top is usually optional.
Key Insight
A service charge is set and collected by the business, while a tip is voluntary. When a service charge already appears on the bill, paying a further tip means paying twice for the same service.
Frequently Asked Questions
What is a service charge?
It is a mandatory percentage a business adds to a bill, common for large groups, hotels, and events. Unlike a tip, the customer does not choose whether to pay it.
Is a service charge the same as a tip?
No. A tip is voluntary and chosen by the customer; a service charge is set by the business and added to the bill automatically.
Do I still tip when a service charge is applied?
Usually it is optional. If a service charge is already on the bill, an extra tip is a discretionary addition, not an expectation.
Does the service charge go to staff?
It depends on the business and local rules. Some pass it to staff, others retain part of it. Policies vary, so it is not always equivalent to a tip.
Is the service charge taxed?
In many places a mandatory service charge is itself subject to sales tax. Check the bill to see whether tax is applied before or after the charge.
