Tip Calculator
A social essential for fair and fast bill sharing.
Tip Calculator
Figuring out the tip at a restaurant — especially when splitting the bill with a group — shouldn't require mental gymnastics. This tip calculator gives you the tip amount, total per person, and customizable tip percentage in seconds.
What Does This Calculator Do?
Enter the bill total, your desired tip percentage, and the number of people splitting the bill. The calculator returns the tip amount, total with tip, and each person's share.
How to Use This Calculator
- Enter the bill total (pre-tip amount).
- Select or enter your tip percentage (15%, 18%, 20%, 25%, or custom).
- Enter the number of people splitting the bill.
- Click Calculate to see tip, total, and per-person amount.
Tip Formula
Tip Amount = Bill Total × (Tip Percentage ÷ 100)
Total Bill = Bill Total + Tip Amount
Per Person = Total Bill ÷ Number of People
Example Calculation
Bill: $85.00 | Tip: 20% | Split: 4 people
- Tip = $85.00 × 0.20 = $17.00
- Total = $85.00 + $17.00 = $102.00
- Per person = $102.00 ÷ 4 = $25.50
Standard Tip Guidelines
- 15%: Acceptable for average service
- 18%: Good service standard
- 20%: Excellent service — and easy mental math (move decimal, double)
- 25%+: Outstanding service or to show extra appreciation
- 10% or less: For genuinely poor service — consider speaking with a manager instead
When Should You Tip?
- Restaurants: 15–25% on the pre-tax amount
- Food delivery: 10–20% or $3–$5 minimum
- Taxi/rideshare: 15–20%
- Baristas (coffee shops): $1–$2 or 10–15%
- Hotel housekeeping: $2–$5 per night
- Hair/nail services: 15–20%
Common Mistakes to Avoid
- Tipping on the post-tax total — etiquette suggests tipping on the pre-tax subtotal, though tipping on the total is also widely accepted and simpler.
- Assuming gratuity is already included — for large parties (6+), many restaurants add an automatic 18–20% gratuity. Check your bill before adding more.
- Forgetting to check if delivery fees go to the driver — many app delivery fees go to the company, not the driver. Always tip the driver separately.
Frequently Asked Questions
What is 20% of $50?
Move the decimal one place ($5.00) and double it = $10.00. This mental math trick works for any amount.
Should I tip on the pre-tax or post-tax amount?
Etiquette traditionally says pre-tax, but tipping on the total is increasingly common and often simpler. Either is acceptable.
Is it rude not to tip?
In the US, tipping is a cultural expectation in service industries, not optional. In many countries (Japan, for example), tipping is not customary and may even be considered rude.
What if service was bad?
A low tip (10–12%) sends a message without being entirely withholding. If service was genuinely terrible due to the server's actions (not kitchen delays), speak to a manager — that's more effective than leaving no tip.
Can I use this for splitting a tab unevenly?
For uneven splits, calculate each person's sub-total separately and use this calculator for each, or use the custom amount entry to split as needed.
Conclusion
Tipping is a social norm in many countries, and calculating it accurately — especially when splitting — takes the awkwardness out of the end of a meal. This tip calculator makes the math instant so you can spend more time enjoying the company.

For takeout orders, a tip of 10% is generally appreciated by the staff who packaged your meal, though it is often considered optional compared to dine-in service.
