Bill Split Calculator
Three free calculators for splitting a bill with friends: an even split with tip, an uneven split with tax and tip, and a settle-up that works out who owes whom after a night of rounds. Pick the one that matches your bill. Amounts are in any currency.
Split a bill evenly
Enter the total, an optional tip and how many people are splitting it.
An even split is the quickest method and the right one when everyone ordered roughly the same. Add the tip to the total first, then divide. Rounding up to the nearest whole amount per person and leaving the difference as extra tip saves everyone hunting for coins.
Example: a bill of €86 with a 10% tip comes to €94.60. Split four ways, each person pays €23.65.
Split a bill unevenly with tax and tip
Enter what each person ordered, plus anything the table shared, such as bottles of wine or starters. Shared items are split evenly; tax and tip are added in proportion, so a bigger order pays a bigger share of both.
Use 0% tax where prices already include VAT, as they do in most of Europe. In the US and Canada, enter the sales tax from the receipt. The tip is calculated on the pre-tax amount, which is the usual convention.
Example: Alex orders €24, Jordan €31, Sam €18 and Taylor €27, and the table shares €20 of starters. Each person's base is their own order plus €5 of starters. With a 10% tip, Alex pays €31.90, Jordan €39.60, Sam €25.30 and Taylor €35.20, which adds up to the €132 total. For the method in more detail, see how to split a receipt item by item and how to split tax and tip on a bill.
Who owes whom after rounds
Bought rounds all night and lost track? Enter what each person spent at the bar. The calculator finds the fair share, then the fewest payments that square everyone up.
This assumes everyone drank about the same amount. If some people had far more or less, an even fair share is not fair, and it is better to split by what each person drank; see how to split a bill when some friends don't drink.
Example: four friends spend €40, €25, €15 and €0 on rounds. The total is €80, so the fair share is €20 each. Alex is €20 up, Jordan €5 up, Sam €5 down and Taylor €20 down. Two payments settle it: Taylor pays Alex €20 and Sam pays Jordan €5.
Which method is fairest?
- Even split: best when orders are similar, or when the group values speed over precision.
- Itemised split: best when orders differ a lot, for example drinkers and non-drinkers at one table.
- Settle-up after rounds: best for a night of rounds where not everyone bought the same number or size of round.
Our guide to bill split methods compares these with percentage and shares-based splits, and how much to tip when splitting the bill covers tipping customs.
Splitting a whole night?
A calculator is fine for one bill. Over a night of rounds, someone always ends up paying more, and nobody remembers the numbers by the end. RoundFair tracks each round as it is bought, shows whose turn it is and who is behind, then settles it fairly.
Frequently asked questions
How do I split a bill with tip?
Add the tip to the total first, then divide by the number of people. For a €60 bill with a 15% tip split three ways, the total is €69 and each person pays €23.
Should tip be calculated before or after tax?
Usually on the pre-tax amount, although tipping on the total is also common and slightly more generous. The uneven calculator above tips on the pre-tax amount.
How do I split a bill when people ordered different amounts?
Give each person their own items, split shared dishes evenly between the people who shared them, and add tax and tip in proportion to each person's share. The uneven calculator does this for you.
How do I work out who owes whom?
Add up what everyone paid, divide by the number of people to get the fair share, and compare each person's spend with it. People below the fair share pay the people above it until everyone is even.
Is it fair to split the bill evenly?
It is fair when orders are similar. When they differ a lot, an even split makes light eaters and non-drinkers subsidise everyone else, so an itemised split is fairer.
