|---|---|---|
| Tip Amount | Bill × Tip % | $85 × 0.20 = $17.00 |
| Total with Tip | Bill + Tip Amount | $85 + $17 = $102.00 |
| Per Person Share | Total ÷ Number of People | $102 ÷ 3 = $34.00 |
Should You Tip Before or After Tax?
In the United States, tipping etiquette suggests tipping on the pre-tax amount. However, for simplicity — and since the difference is small — most people tip on the total bill including tax. Either approach is acceptable. For more tips on percentage calculations, see our guide on how to calculate percentage.
Tip Calculator for Large Groups
When splitting a bill among large groups, rounding up slightly per person ensures the server receives an appropriate tip even when division doesn’t produce clean numbers. Always check if the restaurant has already added a mandatory gratuity (typically 18–20% for groups of 6 or more).
FAQ — Tip Calculator
What is a good tip percentage at a restaurant?
The standard tip at a sit-down restaurant in the US is 18–20% for good service. 15% is considered the minimum for satisfactory service, and 25%+ is appropriate for exceptional service.
How do you calculate 20% tip quickly in your head?
To calculate 20% mentally: move the decimal point one place left to get 10%, then double it. For example, 10% of $85 = $8.50, doubled = $17.00 tip.
Do you tip on the subtotal or the total with tax?
Traditionally, tips are calculated on the pre-tax subtotal. In practice, most diners calculate the tip on the full total for convenience — the difference is usually less than a dollar.
Is it rude not to tip?
In the United States, tipping is a cultural norm in the service industry where workers often rely on tips as a significant portion of their income. Not tipping for standard service is generally considered poor etiquette, though tipping practices vary widely by country.
