How the numbers shift across typical situations for this calculator:
| Scenario | Tip | Total |
|---|---|---|
| $60 bill · 18% | $10.80 | $70.80 |
| $120 bill · 20% | $24.00 | $144.00 |
| $35 bill · 15% | $5.25 | $40.25 |
| $250 bill · 22% | $55.00 | $305.00 |
How This Calculator Works
Enter the bill amount and the tip percentage you want to leave. The calculator multiplies the bill by the percentage to find the tip, then adds it to the bill for the total. In the US, 15% to 20% is a common range for table service, with 18% a frequent default.
The Formula
Percentage Add-On
Rate is the tax or tip percentage applied to the amount
Worked Example
On a $60 restaurant bill, an 18% tip is $10.80, bringing the total to $70.80. Tipping on the pre-tax bill rather than the tax-included figure is the convention, though many people simply tip on the final total for convenience.
Key Insight
Tip on the pre-tax amount if you want to follow the convention precisely, but the difference is small. What moves the tip far more is the percentage chosen — and on a large bill, a few percentage points is a meaningful sum.
Frequently Asked Questions
What is a standard tip percentage?
For US table service, 15% to 20% is typical, with 18% a common middle choice. Exceptional service often warrants more, and norms differ for other services and other countries.
Should I tip on the pre-tax or post-tax amount?
The convention is to tip on the pre-tax bill, but the gap is minor. Many people tip on the total shown for simplicity, which leaves slightly more.
How do I split the total between people?
Divide the calculator's total by the number of people in your group. Each person's share then covers an equal portion of both the bill and the tip.
Do I tip when a service charge is already added?
If a service charge or automatic gratuity already appears on the bill, an additional tip is usually optional. Check the bill so you do not pay twice.
Are tipping norms the same everywhere?
No. Tipping expectations vary widely by country and by service. In some places a service charge is built into the price and extra tipping is not expected.

Methodology & Review
