Tip Calculator by Service Quality
Tip the right amount for the service you got — from poor to exceptional — then split the total evenly across your party.
How it works
Tip = bill × rate for the chosen service level · Total = bill + tip · Per person = total ÷ number of people
Tipping norms in the US sit around 15–20% of the pre-tax bill, with the exact figure signalling how the service was: roughly 15% for adequate, 18–20% for good, and more for service that went above and beyond. This tool maps each quality level to a customary rate, adds it to the bill, and splits the total so everyone at the table pays their share evenly. Tipping on the pre-tax amount is standard, though many people simply tip on the full total for convenience.
Worked example
A $50 bill with "good" service tips at 18%: 50 × 0.18 = $9.00, for a $59.00 total. Split between 2 people, that is $29.50 each, including a $4.50 tip per person.
Frequently asked questions
What is a standard tip percentage?
In US sit-down restaurants, 15% is a floor for acceptable service, 18–20% is standard for good service, and 20%+ rewards service that stood out. Poor service still commonly warrants around 10%.
Should I tip on the pre-tax or post-tax amount?
Etiquette says tip on the pre-tax subtotal, since tax is not part of the service. Many people tip on the full total for simplicity, which only adds a little.
How should I split a tip?
Dividing the total evenly is simplest and used most often. For very uneven orders, some groups tip proportionally to each person’s share of the bill instead.
