About the Split the Bill Calculator
After a meal, someone has to work out what everyone owes. This calculator takes the bill, the tip percentage, an optional tax percentage and the number of people, and gives the tip, the tax, the total and what each person pays. You can round each share up to the next 0.50, 1 or 5, which makes it easy to pay in cash and leaves a small extra as a bigger tip. Type the bill, the tip, the tax, the number of people and the rounding and the bill splitting appears at once, with a few related figures underneath, and you can copy the result with one tap. The sums run in your browser, so nothing you enter is uploaded.

When you need the bill splitting
Friends use it at restaurants and bars, flatmates for shared takeaways, and office groups for team lunches. It is also handy for splitting a holiday rental, with the tip set to zero.
The tip is worked out on the bill before tax, as is common in many places. If you tip on the total including tax, enter a slightly higher tip percentage. For uneven splits, divide the shared items first and add what each person ordered.
How the bill splitting is worked out
Total = bill + bill × tip % + bill × tax %. Each share = total ÷ people, rounded up if you choose. A bill of 120 with an 18 percent tip and 8 percent tax has a tip of 21.60, tax of 9.60 and a total of 151.20. Split four ways, each person pays 37.80. Splitting 100 with a 15 percent tip three ways and rounding up to the next whole amount gives 39 each, 117 in all.
Every answer on this page comes from that one rule, so you can check any result by hand with a calculator. The figures shown underneath, such as other units, are conversions of the same answer.

Mistakes to avoid with bill splitting
Rounding up collects a little more than the total. The extra shown in the results can go in as a tip or be kept as a float. The tool splits equally; it does not handle a person who had a lot more than the others.
On phone and computer
On a phone, type into the boxes one after another and read the bill splitting underneath; Copy result puts it on the clipboard for a message or a note. On a computer the inputs sit on the left and the answer on the right, so you can change one figure and watch the bill splitting move. The split the bill calculator works the same on both. Splitting evenly is easy, but extras change the total. Work out the tip with the Tip Calculator, add a service charge with the Gratuity Calculator, and include tax with the Sales Tax Calculator.
