Tip & Sales Tax Calculator (2026)
Standard US tipping conventions benchmark 15% for adequate service, 18% to 20% for good service, and 22% to 25% for exemplary dining experiences. A frequent point of confusion is whether to calculate tip on the subtotal before sales tax or the final total after tax. Traditional etiquette and accounting best practices state that tips should be calculated on the pre-tax bill subtotal, ensuring you do not pay a gratuity on state and local taxes.
When dining out with groups of friends or coworkers, splitting the check can quickly become awkward. This interactive calculator allows you to input your bill subtotal, toggle between standard tip benchmarks (15%, 18%, 20%, 25%), apply local state/city sales tax, and split the final total evenly across any number of dining guests in real time.

Official guidance, statutory formulas, and IRS benchmarks.
Should I calculate tips before or after sales tax?
Etiquette and financial standards recommend tipping on the pre-tax bill subtotal. Sales tax is a government levy, not a service provided by your waitstaff, so you should not tip on the tax portion of the bill.
What is the standard tipping percentage at US restaurants?
For sit-down dining, 18% to 20% is considered standard for attentive service. 15% is typical for acceptable service, while 22% or higher is customary for exceptional fine dining or complex party accommodations.
What is an automatic gratuity charge?
Many restaurants automatically add an 18% or 20% gratuity for large dining parties (typically 6 or more guests). Always review your itemized receipt before adding additional tip to avoid tipping twice on an already included service fee.
How does bill splitting handle uneven orders?
An even bill split divides the combined subtotal, sales tax, and tip equally among all diners. If guests ordered significantly different meals or drinks, itemizing individual orders or using payment apps with receipt scanners is fairer for each diner.
