This split bill calculator makes dividing a restaurant check, group trip or shared expense quick and fair, handling the tip and an even split across any number of people. It is built for friends splitting dinner, roommates sharing costs, or anyone who wants to skip the mental maths at the table.
The calculator first works out the tip, then divides the grand total evenly. The formulas are simple: tip = bill × tip% , total = bill + tip, and per person = total ÷ number of people. Enter the bill amount, choose a tip percentage, and set how many people are sharing to see exactly what each person owes.
Splitting the tip along with the bill keeps things fair, since everyone contributes proportionally to the service charge rather than leaving one person to cover it. In the United States a 15–20% tip is customary for sit-down service, though the right amount varies by country and the quality of service.
Add the tip to the bill first, then divide the grand total by the number of people. For example, a $100 bill plus a 20% ($20) tip is $120, split 4 ways is $30 each.
In the United States, 15–20% of the pre-tax bill is customary for sit-down table service, with 20% common for good service. Tipping norms vary by country, so check local custom.
If people ordered different amounts, total each person's own items, add a proportional share of tax and tip, and pay that. For simple gatherings an even split is usually fine and faster.
