Split Bill Calculator

Everyone ordered something different? Tax and tip shared out in proportion.

Everyone ordered something different

Splitting evenly is easy and often unfair: the person who had soup and tap water pays for someone else's steak. Splitting by item is fair and annoying, because tax and tip are charged on the whole check and somebody has to divide them up.

This calculator does the annoying part. Enter what each person ordered and it shares the tax and the tip out in proportion to each subtotal — so the soup pays soup-sized tax and a soup-sized tip.

1
Enter the check
The subtotal, and the tax as a rate or as the dollar amount printed on the receipt.
2
Add each person
Name and what they ordered. Names are optional — they just make the result readable.
3
Check it reconciles
The calculator shows what is assigned versus the subtotal, so a forgotten item cannot silently inflate everyone else.

Why the reconciliation line matters

This is the part most split calculators skip. If you enter four items adding to $80 on a $95 check, something is missing — a drink nobody claimed, a side, a typo. A tool that treats your list as weights will happily distribute 100% of the tax and tip across your $80 and hand back numbers that look right.

They are not right. Everyone in your list just absorbed the missing $15 of tax and tip. So the assigned total is always on screen next to the check subtotal, and it says under, over or exact. You should not have to audit a calculator.

Rounding that does not quietly overcharge

Rounding each person's share up is a normal thing to want — nobody wants to owe 7 cents. But the common implementation is to work out one tip and then divide it, rounding each share up as it goes. Do that with three people and you can collect up to $14.99 more than the bill, with no line explaining where it went.

Round the TOTAL to a multiple of the headcount, then divide. Money is conserved.

So when you ask this calculator to round, it rounds the total first and then divides. The shares still come out clean, and they still add up to the bill. Both things are true at once.

The real cost of splitting the bill

There is actual research on this. Gneezy, Haruvy and Yafe ran an experiment (The Economic Journal, 2004) where diners in groups of six either paid individually or split evenly. Paying individually, they spent an average of 37.3 NIS. Splitting evenly, 50.9 NIS — about 36% more. 80% said they would rather pay individually, and then ordered more anyway once they knew the bill was shared.

The authors named the friction precisely:

Some cost is involved in paying individually. A part of it could be the mental cost of figuring out one's share of the bill, and calculating the portion of the tax and tip that apply to that share. Another part would be the social cost of appearing stingy or unfriendly.

This tool removes the first cost. It cannot do anything about the second one — but it is a lot easier to say “mine was $23.40” than to do long division at the table while five people watch.

Tax figures are state averages and change over time — the amount printed on your receipt always wins. Tipping customs are guidance, not rules.
