Frequently Asked Questions

What is considered a standard tip in the United States?▼

In US restaurants, 15% is considered acceptable, 18% is typical, and 20% or higher is standard for good to exceptional service.

Should I tip before or after tax?▼

Traditional etiquette recommends calculating the tip on the pre-tax subtotal. However, many automated payment terminals default to post-tax calculations.

What does the round up option do?▼

Rounding up adjusts the total bill to the nearest whole dollar amount so that individual payments don't require loose coins.

What is automatic gratuity?▼

Many restaurants automatically add an 18% or 20% gratuity to the bill for parties of 6 or more. Always check your receipt before adding an additional tip.

⚠️ Common Pitfalls to Avoid

•Tipping on sales tax rather than the pre-tax food and beverage subtotal (standard etiquette is tipping on the pre-tax amount).
•Overlooking automatic gratuity already added to the receipt for large parties (commonly 18% for parties of 6 or more).
•Splitting the bill evenly when individuals ordered vastly different price tiers (drinks vs tap water).

💡 Practical Real-World Uses

•Splitting restaurant dinner and bar tabs with coworkers, friends, or roommates.
•Calculating fair gratuity for delivery couriers, rideshare drivers, and hotel staff.
•Tipping personal service professionals such as hair stylists and massage therapists.

Pre-Tax Tipping vs Post-Tax Tipping

✓Pre-tax tipping calculates gratuity solely on food and beverage service, which is the traditional etiquette recommendation.
✓Post-tax tipping calculates gratuity on the final total after municipal and state sales taxes are added, resulting in a slightly higher tip.
