Bill split calculator.
Split a bill with tax and tip, equally or by uneven shares, in any currency. No sign-up, no ads — just the answer, and a link you can paste into the group chat.
How to split a bill
The arithmetic is simple: add tax and tip to the bill, then divide by the number of people. What makes it awkward is everything around the arithmetic — whether to tip on the pre-tax amount, what to do when one person ordered far more than everyone else, and who ends up covering the odd cents.
Splitting equally is the right call more often than people admit. For drinks, taxis, a shared taxi to the airport or a table where everyone ate roughly the same, equal is fast, fair enough, and avoids turning dinner into an accounting exercise. Reach for something more precise when the difference is large enough that somebody would actually mind.
When equal is not fair
Uneven shares are the middle ground, and usually the right one. Give each person a weight: a couple sharing a hotel room takes two shares, someone who skipped the wine takes one where the drinkers take two. It keeps the maths to a single division while roughly matching what people consumed.
Split by item when the orders were genuinely different — one person had a starter and tap water, another had the steak and half the bottle. The rule that matters here is to apply tax and tip in proportion to each person's food, not equally. Splitting the food by item and then dividing the tip evenly quietly charges the cheapest orderer the most, relative to what they ate. There is more on all five methods in our guide to splitting a bill fairly.
Rounding, and the cash problem
Once you divide a real bill by a real number of people, you get a number nobody can pay in cash. Rounding each share up to the nearest unit fixes it and leaves a small surplus, which conveniently covers the tip you were rounding toward anyway. The calculator shows the surplus so nobody has to wonder where the extra went.
When a calculator stops being enough
A calculator answers one bill. The harder problem starts when several people have paid for different things across a weekend or a flatshare, and the question is no longer “what do we each owe for this?” but “who owes who, overall?”. That needs the balances netted off against each other so the group settles in the fewest possible transfers rather than everyone paying everyone.

Common questions
How do you calculate a bill split?
Add the tax and the tip to the bill total, then divide by the number of people. For a 120 bill with 8% tax and a 15% tip, that is 120 + 9.60 tax + 18 tip = 147.60, or 36.90 each between four people. The calculator above does this instantly and handles uneven shares too.
Should you tip on the pre-tax or post-tax amount?
Tipping on the pre-tax amount is the more common convention, on the reasoning that you are tipping the server rather than the government. Tipping on the post-tax total is simply more generous. The difference is small on most bills — on a 120 bill with 8% tax, tipping 15% post-tax costs about 1.44 more. The calculator lets you choose either.
How do you split a bill when people ordered different amounts?
Two options. Use uneven shares when the difference is roughly proportional — someone who drank twice as much gets two shares. Split by item when the orders were genuinely different, assigning each dish to whoever ate it and dividing tax and tip in proportion. Equal splits are fine for drinks and taxis and unfair for a table where one person ordered the steak.
How do you split a bill with tax and tip fairly?
Apply tax and tip proportionally to what each person actually spent, rather than dividing them equally. If your share of the food was 40% of the bill, you pay 40% of the tax and 40% of the tip. Splitting the food by item but the tip equally quietly overcharges whoever ordered least.
Is this bill split calculator free?
Yes, completely free with no sign-up and no ads. Enter the numbers and get the answer, then copy a link to share the result with the group.
How do I work out who owes who after a trip?
A calculator handles a single bill. Once several people have paid for different things, you need to net the balances off against each other so the group settles in the fewest possible payments. That is what the EconoGlance app does automatically — it tracks every expense and reduces a tangle of debts to a short list of transfers.
