How to Calculate a Tip: The Complete US Guide

Figuring out how much to tip doesn't have to be stressful. Whether you're at a restaurant, in a taxi, or checking out of a hotel, this guide covers everything you need to know about tipping in the United States — including quick mental math tricks so you never have to pull out your phone.

The Quick Rule of Thumb

For most services in the US, a tip of 15% to 20% of the bill is considered standard. 15% is the floor for acceptable service; 20% is the new normal in most cities for good service; anything above 20% signals exceptional service.

Mental Math: How to Calculate a Tip Without a Calculator

Here's a trick that works for any bill amount:

Step 1: Find 10% by moving the decimal point one place to the left. On a $74 bill, 10% = $7.40.

Step 2: Use that as your building block:

• 15% = 10% + half of 10% → $7.40 + $3.70 = $11.10
• 20% = 10% × 2 → $7.40 × 2 = $14.80
• 25% = 20% + half of 10% → $14.80 + $3.70 = $18.50

How Much to Tip at a Restaurant

Sit-down restaurants are where tipping matters most in the US. Servers typically earn a base wage well below minimum wage and rely on tips to make up the difference. The standard range is 15%–20%, with 20% becoming increasingly common in cities like New York, San Francisco, and Chicago.

For large groups, many restaurants automatically add an 18%–20% gratuity to the bill. Always check before adding an additional tip.

How Much to Tip for Food Delivery

For app-based delivery (DoorDash, Uber Eats, Grubhub), 15%–20% of the order total is the standard. For longer distances or bad weather, tipping higher is appreciated. The tip is usually set before delivery, so consider the effort involved when you place the order.

How Much to Tip a Taxi or Rideshare Driver

For taxis and rideshare drivers (Uber, Lyft), 15%–20% is standard. Most apps prompt you to tip after the ride, which makes it easy. For exceptional service — helping with heavy luggage, navigating efficiently — 20% or more is appropriate.

Tipping at a Hair Salon or Barbershop

For hairstylists, barbers, nail technicians, and estheticians, 15%–20% is the norm. If you're happy with your regular stylist, tipping consistently builds goodwill and often results in better service over time.

Do You Have to Tip?

Technically no — tipping is voluntary in the US. But in practice, not tipping a restaurant server is considered rude and leaves them significantly underpaid given the US wage structure for tipped workers. For other services where tipping is less expected (plumbers, mechanics, etc.), it's a genuine bonus rather than an obligation.
