Step 3: If you are dining with others, enter the number of people to split the bill. The calculator will show each person’s share including their portion of the tip.
Step 4: Review the breakdown showing the tip amount, total bill, and per-person cost. Use the round up option to round to a clean dollar amount for easier payment.
When to Tip More or Less
Consider tipping above 20% for exceptional service, large party accommodations, special requests, or holidays when staff are working instead of celebrating with family. Many restaurants automatically add an 18-20% gratuity for parties of 6 or more — check your bill before adding extra.
Tipping below 15% is generally reserved for poor service. If the food was the issue rather than the server’s attentiveness, consider tipping normally and speaking with management instead — servers typically have no control over kitchen delays or food quality.
How to Calculate a Tip
Calculating a tip is straightforward: multiply the bill amount by the tip percentage (as a decimal). For example, to leave a 20% tip on a $60 bill: $60 × 0.20 = $12.00. The total you’d pay is $60 + $12 = $72.00.
Quick mental math shortcut: To calculate 10%, simply move the decimal point one place to the left ($60 → $6.00). For 20%, double that amount ($6 × 2 = $12). For 15%, add half of 10% to the 10% amount ($6 + $3 = $9).
Standard Tipping Etiquette
Tipping customs vary by country. In the United States, these are typical guidelines:
Sit-down restaurants: 15–20% of the pre-tax bill is standard. 18% is the most common default.
Buffet: 10–15% is typical.
Takeout: 10–15% is increasingly common, though not always expected.
Delivery: 15–20%, with a minimum of $3–5.
Coffee / counter service: $1–2 per drink, or 15–20% of the order.
Bartender: $1–2 per drink, or 15–20% of the tab.
In many European and Asian countries, tipping is less common or already included in the bill as a service charge. Always check whether a gratuity has been added before tipping extra.
How to Split a Bill
To split a bill evenly, first calculate the total including the tip, then divide by the number of people. For example, a $120 bill with an 18% tip: $120 × 0.18 = $21.60 tip, total = $141.60. Split 4 ways: $141.60 ÷ 4 = $35.40 per person.
When splitting unevenly, have each person calculate their share of the food, then add the same tip percentage to each individual share. This ensures the tip is proportional to what each person ordered.
