# Tip Calculator

## Calculator Use

Calculate a tip or gratuity and add it to your check or bill. Enter the check amount and percent tip you want to leave. If you are splitting the check at a restaurant or bar input how many people and see the total amount each person pays.

## How to Calculate Tip

It is customary to leave a tip or gratuity for waitstaff and bartenders to recognize the quality of service a customer receives. People generally tip 15-20% of the bill.

To calculate tip multiply the total check by 1 plus the decimal percentage tip you'd like to leave. If you wanted to leave a 20% tip, you would add 1 to 0.20 to get 1.20. Multiply the bill by 1.20 to get the total amount you'd leave including tip.

- Decide on tip percentage
- Add the decimal form of tip percentage to 1 to get your rate
- Multiply the bill by your rate

Alternatively you can calculate the percentage tip and then add it to the bill. You will get the same end result as using the tip calculation method above.

- Decide on tip percentage
- Multiply the bill by tip percentage as a decimal. This is the amount of tip you're leaving.
- Add this amount to the bill

Increasingly, restaurants and other establishments include gratuity in the bill for larger parties. You can use the Tip Calculator to double-check the accuracy of those tip charges, or to leave a different gratuity amount if permitted.

## How to Calculate Tip on Your Phone's Calculator

Calculating gratuity or tip on a calculator is a simple multiplication. Since the tip is figured as the bill times a percentage you can do one calculation to find the total amount you'll leave including tip. Use the rate 1 + tip percentage as a decimal and multiply that by your check amount.

If you want to leave 18% for your server, multiply your bill amount by 1.18. The result is the total amount you'll pay.

If you need to know exactly how much your gratuity is, multiply the bill amount by 0.18. This is your tip amount. Add this to the bill to get the total amount you'll pay.

### Example Tip Calculation

Say you and a friend had dinner and the check came to $26.50. You had good service and want to leave an 18% gratuity. Put the percentage in decimal form as 0.18 then multiply the check amount by this number.

26.50 * 0.18 = 4.77. So your tip is $4.77.

An easy way to get the total amount of the dinner plus tip is to multiply the total check by 1.18.

26.50 * 1.18 = 31.27

## How to Calculate Tip in Your Head

You can get a good approximation of tip amount by doing it in your head.

Find 10% of your bill by moving the decimal one place to the left. If 26.50 is 100% then 2.65 is 10%. Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30.

Now you know the tip you could leave ranging from poor to good, 10% to 20% is $2.65 to $5.30. To find 15% which is halfway in between take the 10% and add half of that which would be another 5%. 2.65 plus about 1.30 is 3.95.

Now you have

**10% is 2.65** - by moving decimal 1 place to the left

**15% is 3.95** - 10% + half of 10%

**20% is 5.30** - 10% * 2

This is plenty of information to make a good guess at the tip amount you should leave. If you decide on about 18%, 4.50 to 5.00 would be a safe guess.

When leaving a tip for a service you might want to tip an amount that is not calculated based on the amount of the bill or expense. In this case you would want to come up with a gratuity amount that you're comfortable with, one that would demonstrate your gratitude for the service you have received by the service provider.
