The short version
- Bonus saver accounts pay a higher rate when you meet conditions each month.
- Common conditions: grow the balance, deposit a set amount, or make no withdrawals.
- Miss them and you earn only the low base rate that month.
How bonus savers work
A bonus saver pays a low base rate plus a bonus in any month you meet the bank's conditions. Miss a condition and you get only the base rate for that month, which can be a big drop.
Use the planner above and choose "I'll meet them" or "Base rate only" to see both outcomes for your balance.
Common conditions
- Deposit a minimum amount each month, often $20 to $1,000 from outside the bank.
- Grow the balance by the end of each month.
- Make no withdrawals during the month.
- Make a few card purchases from a linked everyday account.
Watch the balance caps
Many bonus rates apply only up to a set balance, such as $50,000 or $100,000, with a lower rate above it. If you have more saved, check the rate on your whole balance.
Pros
- Some of the highest savings rates around, when you meet the conditions.
- The conditions build a regular saving habit.
- No fees on most accounts.
Cons
- Miss a condition and you drop to a low base rate for the month.
- Balance caps can limit the bonus on bigger balances.
- Conditions can change, so check them now and then.
Alternatives
- A savings account with no conditions, which pays the same rate whatever you do.
- A term deposit, which locks your rate for a set time. It suits money you won't need, and protects you from rate cuts.
- A home loan offset account, if you have a mortgage. Every dollar cuts the interest you pay, with no tax on the saving.
How to open one
Most banks let you open a bonus saver online in about ten minutes.
- Have your ID ready. A driver's licence or passport, and your tax file number so you're not taxed at the top rate on the interest.
- Link an everyday account. Most savings accounts move money through a linked transaction account, often with the same bank.
- Set up a regular transfer. An automatic transfer on payday makes saving the default, and helps meet any deposit condition.
