Could your cash buffer cover the next surprise bill?

A cash buffer cannot stop a car repair, urgent dental bill or broken appliance. It can change what happens next.

Moneysmart describes an emergency fund as money set aside for urgent or unexpected costs. Its long-term guide is three months of expenses, while also recognising that even a small start is useful.

Run the three-level check

First, add the money you could use today from transaction, savings or offset accounts. Do not include your credit limit, super, money already reserved for rent or bills, or an investment that may take time to sell.

There is no pass or fail. The first level you cannot cover shows the size of the gap you may want to plan around.

Protect money that already has a job

A bank balance can look available when part of it is already committed. Subtract rent or mortgage payments, scheduled debt repayments, groceries, transport and essential bills due before the next pay.

The remainder is a more honest picture of your accessible buffer. Do not count a credit card or BNPL limit as savings because using it creates another repayment and may add interest or fees.

If the result is lower than you expected

Pick a first target that is realistic. If $2,000 feels remote, start with the expense most likely to occur in your household.

1. Keep the buffer in a separate savings or offset account.
2. Automate a small transfer after payday.
3. Send one-off money, such as a refund, into the same account when you can.
4. After using the buffer, keep the transfer running so it rebuilds.

If there is no room after essentials, the next step may be hardship support or free financial counselling rather than another savings target.
