How Much Should You Tip?

Not sure whether to leave 15%, 18%, 20%, or 25%? Use the NumoCrunch Tip Calculator to quickly compare different tip amounts before you pay. Simply enter your bill amount, choose your tip percentage, select how many people are splitting the bill, and see the tip, total, and amount each person pays. No mental math. No guessing. Just crunch the numbers.

How to Calculate a Tip

Calculating a tip is simple:

Tip = Bill Amount × Tip Percentage

Convert the tip percentage to a decimal and multiply it by the bill — the same math as the What Is X% of Y? calculator. To jump straight to the bill including tip, use the Increase by Percentage calculator.

Example: 20% Tip on $100

20% = 0.20
$100 × 0.20 = $20 tip
Your total bill is $100 + $20 = $120

Tip Calculator With Bill Split

Dining with friends, family, or coworkers? NumoCrunch can calculate the tip and divide the final bill between multiple people.

Example

Restaurant bill: $120
Tip: 20%
Number of people: 4

Tip: $120 × 20% = $24

Total: $120 + $24 = $144

Split four ways: $144 ÷ 4 = $36 per person

How to Split a Restaurant Bill With Tip

When everyone is splitting the bill evenly, calculate the tip first and then divide the total.

Amount Per Person = (Bill + Tip) ÷ Number of People

For example, an $86.40 bill with an 18% tip produces approximately a $15.55 tip and a $101.95 total — split four ways that is $25.49 each. NumoCrunch does the calculation automatically.

15% Tip Calculator

To calculate a 15% tip, multiply your bill by 0.15. For example, $80 × 0.15 = $12. Total with tip: $80 + $12 = $92.

18% Tip Calculator

For an 18% tip, multiply the bill by 0.18. For example, $75 × 0.18 = $13.50. Total: $75 + $13.50 = $88.50.

20% Tip Calculator

For a 20% tip, multiply the bill by 0.20. For example, $65 × 0.20 = $13. Total: $65 + $13 = $78.

Quick 20% Tip Trick

Finding 20% mentally is easy: find 10% of the bill and double it.

For a $70 bill: 10% = $7
20% = $14

25% Tip Calculator

For a 25% tip, multiply the bill by 0.25. For example, $60 × 0.25 = $15. Total: $60 + $15 = $75.

Another shortcut: 25% is one-fourth of the bill.

Round Your Restaurant Bill to the Next Dollar

NumoCrunch can also round your final bill to the next whole dollar. This is useful when you want an easy total instead of dealing with cents. For example, a calculated total of $83.27 becomes a rounded total of $84.00. The calculator automatically adjusts the final amount for you.

What Percentage Should You Tip?

There is no single tip percentage that applies to every situation. For many U.S. restaurant situations, customers commonly consider percentages such as:

15% — a moderate tip
18% — a commonly selected tip
20% — an easy-to-calculate standard choice
22% — a little more
25% — a generous tip

Your final tip can depend on the type of service, local customs, service quality, group size, and whether a gratuity or service charge has already been added to the bill. Always check the receipt before adding an additional tip.
