Quick Answer
A tip calculator finds your tip amount by multiplying the bill total by your chosen tip percentage, then adds that to the bill for your total — and divides by the number of people if you're splitting.
How It Works: Formula & Variables
Tip Amount = Bill Total × (Tip % ÷ 100); Total Bill = Bill Total + Tip Amount; Per Person = Total Bill ÷ Number of People
- Bill Total
- The amount owed before tip, as shown on the receipt.
- Tip %
- The percentage of the bill you choose to leave as a tip, commonly 15-25%.
- Number of People
- How many people are splitting the total bill and tip evenly.
Worked Examples
Example 1: Solo diner
Sam's bill comes to $48 and they leave a 20% tip. The tip amount is $48 × 0.20 = $9.60, for a total bill of $57.60.
Example 2: Group of five
A group of 5 friends has a $215 bill and leaves an 18% tip. The tip amount is $215 × 0.18 = $38.70, for a total bill of $253.70. Split evenly, each person pays about $50.74, including $7.74 in tip.
Key Concepts
Pre-tax vs. post-tax tipping: Tipping on the pre-tax subtotal is traditional, but many people now tip on the full post-tax total for simplicity.
Standard U.S. tipping ranges: 15% is considered a baseline, 18-20% is typical for good service, and 25%+ is reserved for exceptional service.
Splitting evenly vs. by item: Splitting the total evenly is simplest, but groups with very different orders sometimes split by what each person actually ordered.
Common Mistakes
Tipping on post-tax total unintentionally: Not realizing whether you're tipping on the pre-tax or post-tax amount can change your tip by a noticeable amount.
Not rounding cash tips: Forgetting to round cash tips to a convenient amount can leave servers with awkward change.
Splitting evenly when orders were uneven: Dividing the bill equally can be unfair when one person ordered far more or less than the rest of the group.

Tipping on the pre-tax subtotal is the traditional standard, though tipping on the total (including tax) is increasingly common and not considered incorrect.
Add the tip to the bill total, then divide the combined total by the number of people. This calculator does that automatically when you enter the number of diners.
