Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Service charge | Total |
|---|---|---|
| $200 · 18% | $36.00 | $236.00 |
| $500 · 20% | $100.00 | $600.00 |
| $85 · 15% | $12.75 | $97.75 |
| $1,200 · 12% | $144.00 | $1,344.00 |
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.

Where the charge sits on the bill — base, tax, and total
The calculation is a clean percentage of the bill, but the order in which a venue stacks the charge against sales tax decides what you actually owe. Most U.S. receipts apply the service charge to the pre-tax subtotal and then tax the combined figure, because a mandatory service charge is treated as part of the taxable sale rather than a voluntary tip. That means an 18 percent charge on a $200 meal is $36, and the sales tax is then levied on $236 — not on $200 — so the charge quietly enlarges your tax base. This tool isolates the charge and the new subtotal; read the receipt to see whether tax is applied before or after.
Reliability hinges on classification, not arithmetic. A voluntary tip you choose belongs to staff and is usually outside the taxable sale, while a mandatory service charge is business revenue the venue may or may not pass on. If a line is labelled service charge, automatic gratuity, or large-party fee, assume it is mandatory and already counted as gratuity, so an extra tip is optional. When the wording is ambiguous, ask whether the charge reaches the server and whether tax is calculated on top of it before adding anything further — that single question prevents both double-tipping and an overstated total.

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.
When is this calculator unreliable?
Less reliable when service charge vs tip legal distinction (service charge = revenue, taxable to business; tip = employee property), when auto-gratuity disclosure required, when whether distributed to staff (varies), when tax on service charge, when double-charging (service charge + suggested tip), when state laws (some require disclosure), or when delivery app service fees separate from tips. Auto-gratuity = already tipped.
