A tip calculator is a financial utility tool that computes the gratuity amount, total bill, and per-person share based on a pre-tax subtotal and a chosen tip percentage, eliminating mental arithmetic at restaurants, cafés, and service venues. Standard tip percentages range from 15% for adequate service to 20–25% for excellent service, with per-person splitting functionality making it practical for groups of any size.
What Is a Tip Calculator?
Enter your bill amount and tip percentage above to instantly calculate how much to tip, your total, and each person's share. A tip calculator — also called a gratuity calculator — is a tool that calculates the tip amount, total bill, and per-person split based on a bill subtotal and chosen tip percentage.
Instead of doing the math by hand, this free gratuity calculator instantly tells you how much to tip, what the total comes to, and exactly how much each person owes when splitting the bill.
How do I calculate a 20% tip?
Multiply the bill amount by 0.20. For example, a $50 bill with a 20% tip equals a $10 tip, making the total bill $60.
| Tip Amount | Bill Amount × Tip Percentage |
| Total Bill | Bill Amount + Tip Amount |
| Per Person Amount | Total Bill ÷ Number of People |
For example, if your bill is $100 and you leave a 20% tip, the tip amount is $20 and the total bill becomes $120.
What is the standard restaurant tip percentage?
In the United States, restaurant tips typically range from 15% to 20%. Many customers choose 18% for good service and 20% for excellent service.
- 10% Tip – Basic or counter service
- 15% Tip – Standard service in many situations
- 18% Tip – Good service
- 20% Tip – Excellent service
- 25%+ Tip – Exceptional service
How do I split a bill evenly?
Add the bill amount and tip together, then divide the total by the number of people sharing the expense. For example, a $120 total split between 4 people means each person pays $30.
Should I tip before or after tax?
Tip on the pre-tax subtotal — that's the technically correct approach, since sales tax goes to the government, not your server. In practice, most diners tip on the post-tax total, which comes out slightly more generous. Either method is widely accepted.
How much should I tip for delivery?
Delivery tips commonly range from 15% to 20% of the order value, though many customers tip more during bad weather, heavy traffic, or exceptional service. The standard delivery tipping guide recommends a $3–5 minimum on smaller orders.
Calculation Methodology
All calculations use standard arithmetic applied to the values you enter. No hidden adjustments are made to the bill amount.
| Value | Formula |
|---|---|
| Tip Amount | bill × (tip% ÷ 100) |
| Total Bill | bill + tip amount |
| Per-Person Total | total ÷ people |
| Per-Person Tip | tip amount ÷ people |
| Rounded Per Person | ⌈ total ÷ people ⌉ (ceiling to next $1) |
When the "round up" toggle is on, each person's share is rounded up to the nearest whole dollar using the ceiling function. The difference is effectively a small additional contribution to the tip pool.
