Split a bill evenly, by custom shares, or by exact amounts, with tip and tax handled, and every share adding back up to the total to the last cent.
The rounding problem
Naive split of 100.00 by 3
33.33 + 33.33 + 33.33
= 99.99. A cent has vanished.
Largest-remainder split
33.34 + 33.33 + 33.33
= 100.00 exactly. Nobody is more than one cent from their true share.
The calculator below handles the arithmetic; our guide on how to split bills fairly covers the harder part, choosing which method actually fits your situation.
You paid the whole bill
138.00
Left your account
138.00
You actually spent
34.50
103.50 is lent, not spent. Only the 34.50 belongs in your spending totals.
