Tip Calculator

Split bills and calculate tips

The Tip Calculator is a fast, responsive tool designed to compute gratuities and split bills among groups. Whether you are dining at a restaurant, buying coffee, or splitting a taxi fare, this calculator helps you find the correct tip and individual shares quickly, without any awkward math at the table.

Splitting a bill can be frustrating, especially when dealing with tax, custom tip percentages, and varying group sizes. This tool simplifies the process: enter the bill amount, select or type a tip percentage, and input the number of people. The calculator updates the results instantly, providing clear figures for everyone.

This application runs entirely in your browser, keeping your calculations private. It loads instantly on any mobile device, making it perfect for quick calculations while dining out. It is a simple, clean, and free tool built to make group transactions easy.

What this calculator computes

This calculator estimates the total tip amount, the combined bill including the tip, and the individual share for each person in your group. The interface features preset buttons for common tip percentages (10%, 15%, 18%, 20%, 25%) for quick selection, as well as an input field for custom percentages.

The primary result is the total amount per person, which represents each individual's share of the bill and tip. Below that, the calculator displays the total tip amount, the tip share per person, and the overall grand total. These figures ensure that everyone in the group knows their contribution, helping you split the bill fairly.

The math behind tip calculations

The calculations are based on simple percentages and division:

Total Tip Amount: Tip = Bill × (Tip Percentage ÷ 100)
Grand Total Bill: Total = Bill + Tip
Total Per Person: Per Person = Total ÷ Number of People
Tip Per Person: Tip Per Person = Tip ÷ Number of People

This standard approach applies the selected tip percentage to the base bill amount, then splits both the base cost and the tip evenly among the group. All operations are calculated locally with decimal rounding to ensure accurate cent values.

Worked example of splitting a bill

Let us walk through a typical dining scenario: a group of 4 people receives a bill for $85.50 and decides to leave an 18% tip. Here is how the calculator splits the costs:

Clear the inputs and enter 85.50 in the Bill Amount field.
Select the 18% preset button (or enter 18 in the tip input field).
Enter 4 in the Number of People field.
The results will display instantly:
- Total Tip Amount: $15.39
- Grand Total Bill: $100.89
- Tip Per Person: $3.85
- Total Per Person: $25.22

Each person pays $25.22, which covers both their food share and their portion of the gratuity, making the transaction simple and transparent.

When to use this tool

This calculator is perfect for casual dining, business lunches, and group outings where a shared bill needs to be split. It is also useful for calculating tips for delivery drivers, taxi fares, salon services, or hotel staff. The responsive mobile layout ensures you can enter numbers quickly, even while on the move.

By automating the math, it prevents errors and reduces the time spent calculating splits at the end of a meal. It is a handy tool to keep bookmarked on your phone's home screen for quick access whenever you dine out.

Important tipping policies to note

While this calculator helps you estimate tips easily, be aware of restaurant policies that can affect your total. Many establishments apply an automatic gratuity (typically 18% to 20%) to parties of six or more. If this occurs, the tip is already included in the bill, and you do not need to add another tip unless you wish to reward exceptional service.

Additionally, note that tipping is historically calculated on the pre-tax subtotal of the bill. However, many people choose to calculate the tip on the post-tax total for convenience. This calculator applies the percentage to whatever amount you enter, so you can input either the subtotal or the grand total depending on your preference.

Frequently asked questions

Should I tip on tax?

It is a matter of preference. Many people tip on the pre-tax subtotal, which is slightly more economical and considered the technically correct base.

What is a standard US restaurant tip?

For sit-down service, 18% is standard and 20% is generous. For exceptional service, 22%–25% is appropriate.

Does this round per-person amounts?

No — the per-person figure is the exact split. If you want to round up so the math is easier in cash, simply increase the tip percentage slightly.

Is it customary to tip on the tax amount?

Tipping is traditionally calculated on the pre-tax food and beverage subtotal. However, tipping on the post-tax total is common and serves as a slightly higher reward for the service staff.

What is a standard tipping percentage in the US?

A standard tip for sit-down restaurant service is typically 15% to 20% of the subtotal. Tips of 10% are often reserved for poor service, while 25% or more represents exceptional service.
