Tip Calculator
Calculate a restaurant tip, total bill, and per-person share in seconds. Choose 15%, 18%, 20%, or 25%, or use the slider for a custom tip percentage.
Calculate Your Tip
Enter your bill, choose a tip percentage, and add the number of people if you're splitting the check.
Enter the amount of your bill before adding the tip.
Enter 1 if you are paying the bill yourself.
Tip Amount
$18.00
Total Bill With Tip
$118.00
Per Person
$118.00
How the result works: the calculator applies your selected tip percentage to the bill, adds the tip to the bill total, and divides the total evenly when more than one person is entered.
Quick Tip Calculator Answer
To calculate a tip yourself, multiply the bill by the tip percentage written as a decimal. For example, an 18% tip on a $100 bill is $100 × 0.18 = $18. The total is $118.
If two people split that $118 bill evenly, each person pays $59. The calculator above does this math automatically so you can change the bill, tip percentage, or number of people without doing the calculations by hand.
What Is a Tip Calculator?
A tip calculator is a simple online tool that calculates how much gratuity to leave on a restaurant bill or another service bill. Instead of doing percentage math in your head, you enter the bill amount and choose the percentage you want to tip. The calculator then shows the tip amount and the final total.
This tool also works as a basic bill splitter. If you are having dinner with friends, enter the number of people sharing the check and the calculator divides the final bill evenly. That gives you a quick per-person amount before you pay.
Tip calculators are useful at restaurants, bars, coffee shops, delivery orders, group dinners, and other situations where you want to calculate a percentage quickly. They are especially handy when the bill includes cents or when several people are splitting the same check.

Tip Calculator Formula
The math behind a basic tip calculator is straightforward. The calculator uses the bill amount and the selected tip percentage to find the gratuity.
Tip Amount
Tip = Bill × (Tip Percentage ÷ 100)
Total Bill
Total = Bill + Tip
Per-Person Amount
Per Person = Total ÷ Number of People
Tip Calculator Examples
Seeing the calculation with real numbers makes it easier to understand. Here are a few common restaurant bill examples.
Example: $50 Bill at 18%
- Bill: $50.00
- Tip: $50 × 0.18 = $9.00
- Total: $50 + $9 = $59.00
Example: $100 Bill at 20%
- Bill: $100.00
- Tip: $100 × 0.20 = $20.00
- Total: $100 + $20 = $120.00
Example: $80 Bill Split 4 Ways
- Bill: $80.00
- Tip at 20%: $16.00
- Total: $96.00
- 4 people: $96 ÷ 4 = $24.00 each
Example: $125 Bill at 15%
- Bill: $125.00
- Tip: $125 × 0.15 = $18.75
- Total: $125 + $18.75 = $143.75
Common Tip Percentages in the US
There is no single tip percentage that applies to every situation. Tipping depends on the type of service, local custom, the quality of service, and your own preference. In the United States, restaurant diners commonly see percentages such as 15%, 18%, 20%, and 25%.
| Tip | Example on $100 | Simple Use |
|---|---|---|
| 10% | $10 | Quick lower-rate calculation |
| 15% | $15 | Common lower-end restaurant tip |
| 18% | $18 | Common restaurant tip choice |
| 20% | $20 | Common higher restaurant tip |
| 25% | $25 | Larger tip when you choose to give more |
These percentages are examples, not requirements. Service charges, automatic gratuity, local practices, and the type of business can all affect what makes sense for a particular bill.
How to Calculate a Tip in Your Head
You can estimate common tips without a calculator if you know a few simple shortcuts. These tricks are useful when you are checking a bill at a restaurant or deciding how much to leave.
10% Tip
Move the decimal one place to the left. A 10% tip on $60 is $6. A 10% tip on $85 is $8.50.
20% Tip
Calculate 10% and double it. For a $60 bill, 10% is $6, so 20% is $12.
15% Tip
Calculate 10% and half of 10%, then add them. On a $60 bill, 10% is $6 and 5% is $3, giving a 15% tip of $9.
Should You Tip Before or After Tax?
This is one of the most common questions about restaurant tipping. The answer can vary by personal preference and local practice. Many people calculate a restaurant tip using the pre-tax subtotal, while others use the final amount shown on the receipt.
This calculator does not have a separate sales-tax field. It applies your selected percentage directly to the bill amount you enter. Therefore, if you want to calculate a tip on a pre-tax subtotal, enter the pre-tax subtotal. If the amount you enter already includes tax, the calculator will calculate the tip on that full amount.
For example, suppose the meal subtotal is $50 and the tax is $4. An 18% tip on the $50 subtotal is $9. An 18% tip on $54 would be $9.72. The difference is $0.72 in this example. Check your receipt and use the method you prefer or the method expected where you are dining.
When to Use a Restaurant Tip Calculator
Restaurant Dinner
Enter the check amount and choose your tip percentage to see the gratuity and final amount before paying.
Group Dinner
Enter the number of diners to divide the total evenly and see what each person owes.
Bar or Drinks
Use the percentage slider when you want to calculate a percentage of a larger tab instead of doing the math manually.
Delivery Orders
Enter the amount you want to use as the tip base and choose your preferred percentage.
How to Split a Bill With Tip
Splitting a restaurant bill is easy when everyone is paying an equal share. First calculate the tip, add it to the bill, and then divide the final amount by the number of people.
Example: A $120 bill has a 20% tip. The tip is $24, making the total $144. If four people split the bill evenly, each person pays $36.
An equal split is only a simple estimate. If one person ordered much more than another person, or someone did not have a meal, the group may want to divide the check another way. This calculator provides an equal per-person split and does not track individual food orders.
Common Tip Calculation Mistakes
Using the wrong bill amount
Make sure you know whether the number you entered is the subtotal, tax-inclusive total, or another amount. Your tip changes depending on the amount used as the tip base.
Forgetting an automatic service charge
Check your receipt for an automatic gratuity or service charge before adding another tip. Some restaurants add a mandatory charge for large parties.
Dividing before adding the tip
For an equal split, calculate the tip and total first, then divide the final amount by the number of people. This keeps the math consistent for everyone.
Confusing 18% with 0.18
A percentage must be converted to a decimal when doing the calculation manually. Eighteen percent is 0.18, twenty percent is 0.20, and fifteen percent is 0.15.
Rounding a Tip and Split Bill
The calculator displays monetary results to two decimal places. That means a calculated amount such as $8.775 is displayed as $8.78. This is useful because US dollar amounts are normally represented to the nearest cent.
When several people split a bill, rounding can occasionally leave a one-cent difference. If the exact total cannot be divided evenly, the group may need to adjust one person's payment by a cent so that all individual payments add up to the final bill.
Tipping for Restaurants, Delivery, and Other Services
Tipping customs are different depending on the type of service. A sit-down restaurant, delivery order, coffee shop, bar, salon, hotel, and other service businesses can have different expectations. There is no universal percentage that applies to every situation.
For a sit-down restaurant in the United States, diners commonly use percentage-based tips. The 15%, 18%, 20%, and 25% options in this calculator make it easy to compare common choices without entering the number manually.
For delivery or takeout, the appropriate amount can depend on the service, distance, order size, and local custom. A percentage can still be used when it makes sense, but you can also use the calculator simply to work out the math for any percentage you choose.
Tip Calculator Limitations
This is a basic tip and equal bill-splitting calculator. It does not read your restaurant receipt, determine local tipping customs, calculate sales tax separately, or decide what percentage you should leave.
It also assumes that everyone in a split group pays an equal share. If your group has different orders, discounts, coupons, gift cards, separate taxes, shared appetizers, or different payment arrangements, the actual split may require additional calculations.
Use the calculator as a quick math tool. Always check the actual receipt for taxes, service charges, automatic gratuity, discounts, and other charges before making a final payment.

Frequently Asked Questions About Tip Calculators
Common questions about calculating tips and splitting restaurant bills.
How do you calculate a tip?
Multiply the bill by the tip percentage divided by 100. For example, an 18% tip on a $100 bill is $100 × 0.18 = $18. Add the tip to the bill to get a $118 total.
What percentage should I use for a restaurant tip?
There is no single percentage that is right for every situation. In the US, 15%, 18%, 20%, and 25% are common percentages that diners may consider depending on the service and circumstances. Local customs and the type of service also matter.
How do I split a restaurant bill with tip?
Add the tip to the bill first, then divide the final total by the number of people. For example, a $100 bill with an $18 tip becomes $118. Split between two people, that is $59 each.
Should I calculate the tip before or after tax?
Practices vary. Many diners calculate the tip from the pre-tax subtotal, while others use the full amount shown on the receipt. This calculator applies the percentage to whatever bill amount you enter, so you can choose the amount that matches the method you want to use.
Can I calculate an 18% tip?
Yes. Click the 18% button or move the slider to 18%. The calculator will instantly update the tip amount and final bill.
Can I calculate a 20% tip?
Yes. Select the 20% preset. For example, a 20% tip on a $75 bill is $15, making the total $90 before any separate tax or charges not included in the amount you entered.
Can I use this as a bill splitter?
Yes. Enter the bill, choose the tip percentage, and enter the number of people. The calculator divides the final bill evenly and displays the amount per person.
Does this calculator calculate sales tax?
No. This version calculates the tip based on the bill amount you enter. If your entered amount already includes tax, the tip percentage is applied to that amount. If you want to tip on the pre-tax subtotal, enter the pre-tax amount.
What if my group does not want to split the bill equally?
This calculator provides an equal per-person split. If people ordered different amounts or some people did not share the same items, you may need to calculate individual portions separately.
Is this tip calculator free?
Yes. You can use the calculator to calculate tips and split bills without creating an account.
