What Is a Tip Calculator?
A tip calculator is a simple tool that works out how much gratuity to leave based on your bill and a chosen tip percentage. It instantly shows the tip amount, the grand total, and — if you are dining with others — how much each person should pay. This removes the awkward mental math at the end of a meal and makes splitting the check effortless.
How to Use It
Enter your bill amount (the pre-tip subtotal), choose a tip percentage (15%–20% is common in the US for table service), and set how many people are splitting the bill. The calculator returns the tip, the total, the total per person, and each person's share of the tip.
The Formula Explained
The math is straightforward percentage multiplication:
$$\text{Tip} = \text{Bill} \times \frac{\text{Tip \%}}{100}$$
$$\text{Total} = \text{Bill} + \text{Tip}$$
When splitting, divide the total by the number of people: $$\text{Per Person} = \frac{\text{Total}}{n}$$ The tip percentage is applied to the bill subtotal; some people prefer to tip on the pre-tax amount, which this calculator assumes by treating your entered bill as the base.
Worked Example
Suppose your bill is $80 and you want to leave an 18% tip, split between 4 people.
Tip = \(80 \times 18 \div 100 = \textbf{\$14.40}\). Total = \(80 + 14.40 = \textbf{\$94.40}\). Per person = \(94.40 \div 4 = \textbf{\$23.60}\), with each person's tip share being \(14.40 \div 4 = \textbf{\$3.60}\).
FAQ
What is a standard tip percentage? In the US, 15%–20% is typical for restaurant table service, with 20% considered generous. Norms vary widely by country.
Should I tip on the total or pre-tax amount? Etiquette guides usually say tip on the pre-tax subtotal. Enter that subtotal as the bill for the most accurate result.
Can I split a tip unevenly? This tool splits evenly. For uneven splits, calculate the tip first, then divide the total according to each person's individual order.
