Four ways to split

Each expense keeps its own split, so a 60/40 rent payment and a 50/50 grocery run can sit side by side in the same balance.

  • Equally between everyone, or between the people you pick.
  • By percentage, for example rent split 60/40 by room size.
  • By shares, for example 2 parts to 1 when one person uses twice as much.
  • By exact amounts, when each person owes a specific sum.

Balances and settling up

Flatsby shows what each person owes or is owed. It simplifies the debts, so the household needs fewer payments to get back to zero.

When someone pays a flatmate back, record it as a settlement and both balances update.

Currencies and categories

Expenses can be in EUR, USD or GBP. Flatsby does not convert between currencies. It keeps a separate balance per currency instead.

Every expense has a category, such as groceries, internet or home goods, so you can see where the money goes.

Rent and other recurring costs

There are no recurring expenses yet. Add rent as a new expense each month.

Questions

Can I move my expenses over from Splitwise?

Yes. Export your group from Splitwise as CSV, then upload it under Group settings, Import expenses. You pick the currency and match Splitwise names to your flatmates. Each expense keeps the exact amount every person owed, so percentage splits arrive as amounts. Rows in other currencies or with several payers are skipped, and the preview lists them first.
