Figuring out how much to tip at a restaurant, hotel, or salon does not have to be a mental math exercise. Our free Tip Calculator gives you the tip amount, total bill, and — when dining with others — the split per person, all in seconds. Enter your bill, choose a tip percentage, and specify how many people are sharing the cost.
Tipping customs vary widely by country and service type. In the United States, 15–20% is standard at sit-down restaurants, while delivery drivers and hotel staff typically receive smaller fixed amounts. This calculator helps you tip appropriately without under- or over-paying.
How Tip Calculations Work
Calculating a tip is a straightforward percentage calculation applied to your bill. The standard approach is to multiply the bill amount by the tip percentage (expressed as a decimal). To split the total with friends, divide the combined amount by the number of people.
Tip Amount = Bill × (Tip % ÷ 100)
Total = Bill + Tip Amount
Per Person = Total ÷ Number of People
For example, a $85 dinner bill with an 18% tip: Tip = 85 × 0.18 = $15.30. Total = $100.30. Split between 4 people = $25.08 each.
Worked Examples
Example 1 — Restaurant dinner for two: Bill = $72.50, tip = 20%. Tip = 72.50 × 0.20 = $14.50. Total = $87.00. Each person pays $43.50.
Example 2 — Coffee or counter service: Bill = $18, tip = 10% (common for counter service). Tip = $1.80. Total = $19.80.
Example 3 — Large group dinner: Bill = $320, tip = 18%, 8 people. Tip = $57.60. Total = $377.60. Per person = $47.20.
Example 4 — Poor service: Bill = $55, tip = 10%. Tip = $5.50. Total = $60.50. Many etiquette guides suggest 10% as the minimum for poor service rather than nothing, as servers often share tips with kitchen staff.
Tip Percentage Quick Reference
| Bill Amount | 10% Tip | 15% Tip | 18% Tip | 20% Tip | 25% Tip |
|---|---|---|---|---|---|
| $20 | $2.00 | $3.00 | $3.60 | $4.00 | $5.00 |
| $40 | $4.00 | $6.00 | $7.20 | $8.00 | $10.00 |
| $60 | $6.00 | $9.00 | $10.80 | $12.00 | $15.00 |
| $100 | $10.00 | $15.00 | $18.00 | $20.00 | $25.00 |
| $150 | $15.00 | $22.50 | $27.00 | $30.00 | $37.50 |
Tips for Tipping Fairly
A common shortcut for calculating a 20% tip is to move the decimal point one place left (getting 10%), then double that number. For a $64 bill: 10% = $6.40, doubled = $12.80. This mental math trick works for any bill amount and is faster than long division.
When a service charge or gratuity is already included on the bill — common for large parties — you do not need to add another tip on top. Look for lines labeled “service charge,” “gratuity,” or “auto-grat” before calculating. Tipping twice effectively means you are paying 30–40% without realizing it.
Frequently Asked Questions
How much should I tip at a restaurant?
In the United States, 15–20% is standard for sit-down restaurant service. 20% is common for good service, 15% for average service, and 10% is generally the minimum for poor service. For exceptional service, 25% or more is always appreciated.
Should I tip on the pre-tax or post-tax amount?
Most etiquette guides recommend tipping on the pre-tax subtotal, since tax is a government charge unrelated to the quality of service. However, the difference is small (usually a dollar or two), so many people simply tip on the total for convenience.
How do I split a bill unevenly?
If people ordered different amounts, the fairest approach is to calculate each person’s share of the subtotal, then add the tip percentage to each individual share. This calculator assumes an even split — for uneven splits, divide based on each person’s order total.
Is it rude not to tip?
In countries where tipping is customary (such as the United States and Canada), not tipping is considered disrespectful to service workers who often rely on tips as a significant part of their income. In other countries (Japan, for example), tipping may be considered unnecessary or even offensive.
Do I tip on alcohol?
Yes, in most cases. At a restaurant, alcohol is typically included in the bill total you tip on. At a bar, the common practice is $1–$2 per drink for simple orders, or 15–20% for table service or complex cocktails.
What if a service charge is already included?
If a service charge or automatic gratuity is already added to your bill, you are not expected to tip again. Check the bill carefully — charges labeled “service fee,” “gratuity,” or “auto-gratuity” mean the tip is already included.
