Split the bill
Divide a total, round it to a sensible unit, and see exactly what is over or short.
The division is easy; the remainder is what causes trouble at the table. Split 47,300 three ways and you get 15,766.67, which nobody is going to transfer. Round up to the nearest 100 and 100 is over; round down and 200 is short. Both are shown rather than hidden.

A unit that is easy to transfer
Each share goes up, so slightly more is collected than the bill. Whoever paid is not left out of pocket.

If one person already paid, rounding up is easier — coming up short means they cover it, which is where the friction is.

Divide, round to the unit, multiply back
Each share is total ÷ people, rounded to the unit you chose. Splitting 47,300 three ways, rounding up to 100, gives 15,766.67 → 15,800. The amount collected is that share × people, 47,400, and collected minus owed leaves 100 over. Rounding down gives 15,700 each, 47,100 collected, and 200 short. Choosing the 1-unit setting only tidies the fraction: rounding up gives 15,767 (1 over), rounding down 15,766 (2 short).
Where nearest parts from up and down
Nearest rounds up when the fractional part of the share divided by the unit is 0.5 or more, and down otherwise. 15,766.67 ÷ 100 is 157.67, which goes up to 158 and lands on the same 15,800 as rounding up. 40,000 split three ways is 13,333.33; ÷ 100 is 133.33, which goes down to 133 and matches rounding down at 13,300, leaving 100 short. Which way nearest falls depends entirely on the total, so if you would rather not come up short, pick up from the start.
The table runs from 2 to 12 people under the same rule
Each row of the table is recomputed from scratch with the same total, unit and mode. The row for the number you entered is highlighted, and over or short is written with + and −. 47,300 rounded up to 100 gives 23,700 for two (100 over), 11,900 for four (300 over) and 9,500 for five (200 over). The surplus from rounding up tends to grow with the group, since each person can overpay by up to 99. Up to 200 people are accepted.
What it does not do
Only equal shares are computed. If someone who did not drink pays less, or the birthday person pays nothing, subtract their share from the total first and reduce the head count. Tips, service charges and delivery fees need adding to the total beforehand, and several receipts are not combined for you. Who keeps the surplus is not decided here — that is settled at the table.
Common questions
QShould I round up or down?
Up, if one person already paid. Coming up short means the payer covers the gap, which is the part that causes friction. Anything over can go towards the next round or be handed back.
QWhy not just split the card payment?
If the venue allows it, that is cleanest. With a large group it takes a while at the terminal, and there is still the case where one person pays for a delivery or a booking up front and settles afterwards.
QIs there a limit on the number of people?
Up to 200 people. A table from two to twelve people is shown alongside, so you can see what one more arrival does to each share before the group is even settled.
QWhen does nearest differ from rounding up?
When the fractional part of the share divided by the unit is below 0.5. 40,000 split three ways is 13,333.33; at a 100 unit that is 133.33, so nearest goes down to 13,300 while up goes to 13,400. Collected totals are 39,900 and 40,200 — one is 100 short, the other 200 over.
QWhat if one person pays more or less?
This page only splits equally. If one person is paying 20,000 separately, subtract 20,000 from the total and enter one fewer person to get the others' share. If the group splits into two, run it twice.
