Tips for Best Results

  • Standard etiquette in the United States recommends calculating the tip on the pre-tax subtotal rather than the post-tax total.
  • Check your restaurant receipt for automated "gratuity included" or "service charge" lines before adding an extra tip for large groups.
  • Tipping percentages represent convenient choices rather than universal mandates; adjust based on service quality and local customs.

Common Use Cases & Practical Applications

1. Restaurant Dining Gratuity Calculations

Quickly select standard gratuity benchmarks (15%, 18%, 20%) on food and beverage bills for attentive table service.

Example: Calculating an 18% tip ($15.30) on an $85.00 dinner bill for a total payment of $100.30.

2. Even Split Among Dining Companions

Divide the combined meal total and tip evenly between 2 to 6 dining partners to settle tabs quickly at the table.

Example: Dividing a $120.00 total bill including tip between 3 friends for exactly $40.00 per person.

3. Service Industry Gratuities (Salon, Taxi, Delivery)

Determine appropriate tips for personal care professionals, rideshare drivers, and food delivery couriers.

Example: Adding a 20% tip ($9.00) to a $45.00 haircut service.

Frequently Asked Questions

Should I calculate the tip before or after sales tax is added?

Etiquette experts universally recommend tipping on the pre-tax food and beverage subtotal. Sales tax is a government levy, and servers do not receive any portion of taxes collected by the restaurant. The tool allows you to calculate both ways.

How does the Pre-Tax versus Post-Tax calculation basis work?

When sales tax is entered, you can choose whether the tip percentage applies strictly to the food and beverage subtotal (pre-tax) or to the combined subtotal plus tax (post-tax). If no tax is entered, the tip is calculated directly on the bill subtotal.

What is customary tipping etiquette outside the United States?

Tipping customs vary globally. In much of Europe, a 5% to 10% tip is standard for good service, or service is included in the bill. In Japan and South Korea, tipping is not practiced and can be considered impolite.

What should I do if a restaurant automatically adds gratuity for large parties?

Many restaurants automatically add an 18% or 20% gratuity for parties of 6 or more. Always check the itemized receipt; if auto-gratuity is included, you do not need to leave an additional tip unless the service was extraordinary.
