Integer-cent remainder allocation

The total is rounded to the nearest cent, divided by the number of people using integer arithmetic, and the remainder is distributed as one extra cent to that many shares.

Base cents = floor(total cents / people); remainder = total cents mod people

Worked example

An amount that does not divide evenly

Inputs: total: 87.50 · people: 3

Illustrative result: 29.16 each; one share adds 0.01

Two base shares are 29.16 and one is 29.17, totaling exactly 87.50.

Frequently asked questions

Why is there an extra-cent count?

Currency amounts cannot be split into fractions of a cent; the remainder shows how many shares need one extra cent.

Does this include a tip?

No. Add any tip or tax to the amount before entering it if your group wants to split those costs too.
