Split the Bill Calculator
Split a bill evenly, with a tip, rounded so nobody fumbles for coins.
Good to know. Rounding everyone’s share up to a whole number ends most bill arguments before they start.
How it works
In plain words
Add the tip to the bill, divide by the number of people, then round each share up to the step you chose. The rounding extra is what the group pays on top.
The formula
total = bill × (1 + tip ÷ 100) share = roundUp(total ÷ people, step) extra = share × people − total
Worked example
A bill of 187.40 with a 10% tip is 206.14. Split six ways that is 34.36 each, rounded up to 35.00 per person.

About the split the bill calculator
Splitting a bill evenly is the fastest and friendliest way to settle up after a group meal. This calculator adds the tip, divides the total, and rounds each share up so that nobody has to pay 34.36 exactly.
Rounding up means the group always pays at least the full bill. The small surplus is shown as "extra from rounding". You can treat it as an extra tip, or let the person who paid the bill keep it for the trouble of collecting everyone’s money.
An even split is simple, but it is not always fair. If one person had a salad and water while another had three courses and wine, it may be kinder to have people pay for what they ordered and split only shared items and the tip. For quick, casual meals, an even split saves time and avoids awkward arithmetic at the table.
Enter the bill total as shown, including any tax. If a service charge is already on the bill, set the tip to 0%. For a closer look at tipping customs and percentages, see the tip calculator.
Questions people ask
How do I split a bill with a tip?
Add the tip to the bill first, then divide by the number of people. 187.40 plus 10% is 206.14, which is 34.36 each for six people.
Why round up rather than to the nearest amount?
Rounding up makes sure the bill is always fully covered. Rounding to the nearest could leave the group a little short.
What happens to the extra from rounding?
That’s up to the group. Most people add it to the tip or give it to whoever paid the bill.
