Tipping is common at restaurants, cafés, hotels, salons, delivery services, and many other places. But working out the right tip—especially when you also want to split the bill—can sometimes be confusing.
A Tip Calculator makes the calculation quick and simple. Enter your bill amount and desired tip percentage to find the tip and total amount to pay.
What Is a Tip?
A tip is an extra amount of money given for good service.
For example, if your restaurant bill is $80 and you want to leave a 15% tip:
Tip = $80 × 15 ÷ 100
Tip = $12
Your total payment would therefore be:
$80 + $12 = $92
How to Calculate a Tip
Use this simple formula:
Tip Amount = Bill Amount × Tip Percentage ÷ 100
Example
Suppose your bill is $120 and you want to leave an 18% tip.
$120 × 18 ÷ 100 = $21.60
So:
Tip: $21.60
Total Bill: $141.60
Common Tip Percentages
Typical percentages people may choose include:
10% — simple or modest tip
15% — commonly used tip
18% — good service
20% — very good service
25% — excellent service
Tipping customs vary by country and situation, so these percentages are examples rather than fixed rules.
Splitting a Bill
A tip calculator is especially useful when several people are sharing a bill.
For example:
Bill: $100
Tip: 20% = $20
Total: $120
4 people: $120 ÷ 4 = $30 each
Instead of doing several calculations manually, a calculator can give you the result instantly.
When Is a Tip Calculator Useful?
You can use it for restaurant meals, food delivery, cafés, taxis, hotels, salons, barbers, and other services where tipping is customary.
It can help you calculate the correct amount quickly and avoid mistakes when paying or splitting a bill.
How to Calculate a Tip Manually
Calculating a tip manually is straightforward when you know the bill amount and the percentage you want to leave.
Use this basic formula:
Tip Amount = Bill Amount × Tip Percentage
Convert the percentage to a decimal before multiplying. For example, 15% becomes 0.15 and 20% becomes 0.20.
If your restaurant bill is $80 and you want to leave a 15% tip:
$80 × 0.15 = $12
The tip is $12, making the total payment:
$80 + $12 = $92
Common Tip Percentage Examples
Different situations may involve different tipping practices, and customs can vary by country, location and type of service.
For a $100 bill, the calculation is especially easy to understand:
10% tip = $10
15% tip = $15
18% tip = $18
20% tip = $20
These examples can also help you estimate a tip quickly when you do not need an exact calculation.
How to Split a Bill With a Tip
When several people share a meal, first calculate the tip and add it to the original bill. Then divide the total by the number of people.
For example, suppose the bill is $100 and a 20% tip is added:
$100 + $20 = $120 total
If four people are sharing the cost:
$120 ÷ 4 = $30 per person
This method gives everyone an equal share of both the bill and the tip.
Things to Check Before Adding a Tip
Before calculating an additional tip, check the receipt to see whether a gratuity or service charge has already been included. This can sometimes happen for larger groups or particular services.
Tipping customs also differ between countries and businesses, so there is no single percentage that applies everywhere. Consider local practices, the type of service provided and any charges already included in the bill.
