Split bill calculator

How the calculator splits a bill

Evenly, it divides the total by the number of people and rounds each share to the cent. Rounding usually leaves a cent or two over, so those cents go, one each, to the first people in the list. Split $100 between three people and the shares are $33.34, $33.33 and $33.33: together, exactly $100.

By percentage, you give each person a share, such as 50, 30 and 20. The percentages need to add up to 100, and the same rounding rule keeps the total exact.

By income, each person pays in proportion to what they earn. With incomes of 3,000 and 2,000, the split is 60/40, which is the usual way couples share household costs when their pay differs.

When one calculation isn't enough

A calculator answers one bill. A trip, a shared flat or a relationship produces dozens of them, paid by different people on different days. That's when a running balance helps more than a calculator:

• every expense is recorded once, with who paid and who it was for;
• balances add up on their own, per currency;
• you settle once, instead of after every bill.
