The spreadsheet only one person opens
It always ends up being the same person who writes it down, who remembers and who chases. And that person gets fed up before anyone else.
One person has the electricity on direct debit, another paid for the big shop and a third fronted the sofa. By the end of the month nobody remembers anything, and the conversation is awkward precisely because nobody has the numbers.
What happens without it
It always ends up being the same person who writes it down, who remembers and who chases. And that person gets fed up before anyone else.
Splitting 84.37 three ways gives 28.123333. Rounding by eye leaves a cent short or spare, and the total stops adding up exactly when somebody checks it.
A owes B, B owes C and C owes A. Without sorting it out, everyone pays their own and three times the necessary transfers get made.
How it gets sorted
Put in the amount, who paid, and who it's between. The split is done in whole cents with the largest-remainder method, so the parts always add up to exactly the total. Not one cent lost to rounding.
Every time it's looked at, it's recalculated from the expenses. That means correcting last week's amount fixes the balances immediately, instead of leaving a discrepancy nobody can trace.
When you settle up we tell you exactly who pays whom and how much, in the smallest number of moves possible: never more than one transfer per person minus one.
If you use the shopping list, marking the receipt as paid brings the expense in already split. The one case people most often forget to record stops depending on anyone remembering.
