Shared costs, on terms you agree.

Set the agreement per expense

Percentages suit a shared ratio; exact amounts suit a fixed contribution.

  1. Create a shared group and invite your partner.
  2. Choose the payer and the split method for the bill.
  3. Check each person’s amount together before saving.

See your own cost

Personal can include your share of group bills alongside solo purchases. Use inclusion controls and source links to avoid counting a payment twice. Paying 100 upfront does not make all 100 your personal spending.

Review shared and personal spending

Use running balances for the shared ledger and private category insights for your own recorded costs. This is not a joint bank account or bank-feed connection. Repayments happen through your chosen payment method and are then recorded here.

Common questions

How should couples split bills fairly?

There is no single right answer. Many couples split shared costs equally, by income percentage or with fixed amounts. AA split lets you choose per bill, so rent can be 60/40 while groceries are equal.

Is AA split a joint bank account?

No. It records shared costs and repayments between partners. Money moves through your own bank or payment app, and each partner keeps their own Personal spending view.
