How to Calculate a Tip
Calculating a tip is straightforward. The formula is simple: multiply your bill amount by the tip percentage you want to leave. For example, if your bill is $50 and you want to leave a 20% tip, you would calculate $50 × 0.20 = $10 tip. Your total bill would be $50 + $10 = $60.
Our tip calculator above does this math instantly for you. Just enter your bill amount, select your tip percentage using the slider or quick buttons, and see the results immediately. You can also split the bill between multiple people if you're dining with a group.
Quick Tip Percentages Guide
15% Tip - When to Use
A 15% tip is the minimum standard for acceptable service in most US restaurants. Use 15% when:
- Service was adequate but not exceptional
- You're at a casual dining restaurant
- The server was attentive but slow
- You're on a tight budget
Example: $50 bill × 15% = $7.50 tip
18% Tip - Standard Practice
18% is the standard tip for good service at most restaurants. This is what most people leave for normal, satisfactory service. Use 18% when:
- Service was good and prompt
- Your server was friendly and attentive
- You're at a mid-range restaurant
- Everything met your expectations
Example: $50 bill × 18% = $9.00 tip
20% Tip - Good Service
20% is considered a generous tip for excellent service. This is becoming the new standard in many cities. Use 20% when:
- Service was excellent and prompt
- Your server went above and beyond
- You're at an upscale restaurant
- You had a special occasion (birthday, anniversary)
Example: $50 bill × 20% = $10.00 tip
25% Tip - Exceptional Service
25% is for truly exceptional service. This is rare but appropriate when:
- Your server provided outstanding, personalized service
- The restaurant went out of their way to accommodate you
- You're a regular and want to show appreciation
- You had an extraordinary dining experience
Example: $50 bill × 25% = $12.50 tip
How to Split a Bill
Splitting a bill is common when dining with friends, family, or coworkers. Here's how to do it:
Step 1: Calculate the total bill including tip. Our calculator does this automatically when you enter the bill amount and select your tip percentage.
Step 2: Use the split feature to select how many people are sharing the bill. You can split between 2-20 people.
Step 3: The calculator shows you the per-person amount instantly. Each person knows exactly how much they owe.
Example: If your bill is $100 with a 20% tip ($20), the total is $120. Split between 4 people, each pays $30.
When to Split Evenly vs Proportionally
Split evenly when everyone ordered similar amounts, you're keeping things simple, or the group agrees to split evenly. This is the most common approach.
Split proportionally when some people ordered expensive items while others didn't, someone doesn't drink alcohol, or the group prefers fairness over simplicity. Our calculator doesn't currently support proportional splitting, but you can calculate it manually by dividing each person's items.
Tipping Etiquette in the United States
Tipping customs vary by country. In the United States, tipping is expected in most service industries because many service workers rely on tips to supplement their income. The federal minimum wage for tipped workers is only $2.13 per hour, making tips essential.
For restaurant servers, the standard tip is 15-20% of the pre-tax bill. For bartenders, it's $1-2 per drink or 20% of the total tab. For food delivery, tip 10-15% with a minimum of $3-5, depending on distance and weather conditions.
Remember that tipping is voluntary, but it's an important part of service industry compensation in the US. If service was truly exceptional, consider tipping above the standard 20%. If service was poor, you can tip less, but it's usually better to speak with a manager about the issue.
Some restaurants automatically add a gratuity for large groups (usually 6+ people). Check your receipt to see if this has been done. If gratuity is already included, you don't need to add an additional tip unless you want to reward exceptional service.

How do you calculate a 20% tip?

Should I tip on the total or subtotal?

Is it rude not to tip?
In the United States, not tipping is generally considered rude for sit-down restaurant service. Servers rely on tips as a significant part of their income. The only exceptions are if service was exceptionally poor or if you're at a business where tipping isn't expected.
How much to tip for takeout?
Tipping for takeout is optional but appreciated. Consider 10% for large or complicated orders, or $2-5 for simpler orders. If the staff helped pack your order carefully or provided extra service, a tip is a nice gesture.
What's the difference between tip and gratuity?
There's no difference in meaning. 'Tip' and 'gratuity' are interchangeable terms for the extra money given to service workers. 'Gratuity' is more formal and often appears on receipts or in upscale restaurants.
Do I need to tip if a gratuity is already added?
If a gratuity is already added to your bill (common for large groups of 6+ people), you don't need to add an additional tip unless you want to reward exceptional service. Check your receipt to see if gratuity is included.
