What is a Split Bill Calculator?

A split bill calculator is a practical tool that divides a restaurant bill or shared expense evenly among a group of people. It calculates the tip, applies tax, and shows exactly how much each person owes. This split bill calculator is designed for the American dining experience, where tipping is customary and sales tax is added separately to the bill.

How the Split Bill Calculator Works

The split bill calculator takes your bill subtotal, tax, tip percentage, and the number of people splitting the bill, then computes the per-person amount. It supports both pre-tax and post-tax tipping and can round up the per-person amount.

Tip Amount = Tip Base × (Tip % / 100) Tip Base = Subtotal (pre-tax) or Subtotal + Tax (post-tax) Total Bill = Subtotal + Tax + Tip Amount Per Person = Total Bill / Number of People Rounded Per Person = Round up to nearest dollar or $0.10

The split bill calculator first determines the tip base depending on whether you choose to tip on the pre-tax subtotal or the post-tax total. Most etiquette experts recommend tipping on the pre-tax amount. It then calculates the tip, adds everything together, and divides by the number of people. If you choose to round up, the calculator adjusts each person's share upward and shows the total extra collected.

Key Features of the Split Bill Calculator

Tip Calculation

The split bill calculator includes quick-select buttons for common US tip percentages: 15% (minimum), 18% (standard), 20% (good service), 22% (great service), and 25% (exceptional service). You can also enter a custom percentage. The tip is calculated based on either the pre-tax subtotal or the post-tax total, depending on your preference.

Pre-Tax vs. Post-Tax Tipping

There is an ongoing debate about whether to tip on the pre-tax or post-tax amount. The split bill calculator supports both approaches. Tipping on the pre-tax subtotal is recommended by most etiquette experts because tax is collected by the government and is not part of the restaurant's service. However, many people simply tip on the total at the bottom of the receipt.

Rounding Options

When splitting a bill, uneven amounts like $23.47 per person can be awkward. The split bill calculator offers rounding options to simplify payment. You can round each person's share to the nearest dollar or to the nearest ten cents. The calculator shows the total extra amount collected from rounding, which can be added to the tip.

Frequently Asked Questions

How do you split a restaurant bill with tip?

Add the tip to the bill total, then divide by the number of people. For example, an $85.50 bill with $6.20 tax and 18% tip on pre-tax ($15.39) totals $107.09. Split 4 ways, each person pays $26.77. This split bill calculator does all the math automatically.

Should you tip on the pre-tax or post-tax amount?

Most etiquette experts recommend tipping on the pre-tax subtotal. The tax is collected by the government and is not part of the service the restaurant provided. This split bill calculator lets you choose either option so you can follow your preferred approach.

What is the standard tip percentage in the US?

The standard tip for restaurant table service in the US is 15% to 20% of the pre-tax bill. 15% is the minimum for adequate service, 18% is standard, and 20% or more is for excellent service. This split bill calculator includes quick-select buttons for the most common tip percentages.

How do you split a bill when people ordered different items?

When people order items of different prices, the fairest approach is to have each person pay for their own items plus their proportional share of tax and tip. This split bill calculator provides the even-split amount as a baseline, but for uneven splits you should calculate each person's share separately based on what they ordered.
