Agree the split, bill by bill

Families rarely split everything equally. Use percentages for an agreed ratio, exact amounts for fixed contributions or weighted shares for households of different sizes.

  1. Create a family group and invite relatives with a link.
  2. Set up regular costs as a weekly, monthly or yearly recurring expense, with an optional end date.
  3. Add one-off costs with their own payer, participants and split.

Relatives in different countries

Each expense keeps its original amount and currency. Use a daily reference rate with no AA split markup or the rate your bank charged, so relatives paying from abroad see the same balance in the group’s settlement currency.

Separated parents and shared child costs

Co-parents can record school fees, activities and medical costs with an agreed percentage, keep receipt details beside each cost and export CSV, Excel or PDF records for free. Choose how long receipt photos are kept; saved expense details remain after a photo expires. AA split is a shared ledger, not a legal record, mediation service or joint account.

Common questions

Can siblings share a parent’s care costs in AA split?

Yes. Create a family group, choose the split you agreed, such as 50/30/20, and record regular costs as a recurring expense. One-off bills can follow a different split. Pay each other your usual way and record the repayment.

Can separated parents split child expenses?

Yes. Record each cost with the agreed percentage or exact amount, keep receipt details beside it and export records for free. AA split does not move money, verify payments or replace legal advice.

Can we split a family holiday in different currencies?

Yes. Record each expense in its original currency, then use a daily reference rate with no AA split markup or the rate your bank charged. Review the converted balance before anyone settles up.
