Fixed term deposits remain one of the safest investment options for Australians looking to grow their savings with guaranteed returns.

Understanding Fixed Term Deposits at Commonwealth Bank
A fixed term deposit is a savings product where you agree to lock away your money for a predetermined period (the “term”) at a fixed interest rate. In return, you receive guaranteed interest payments and the return of your principal at maturity.
Key Features of CBA Term Deposits:
- Guaranteed returns – Your interest rate is fixed for the entire term
- Flexible terms – From 1 month to 5 years
- Interest payment options – Paid at maturity, monthly, quarterly, or annually
- Government guarantee – Up to $250,000 per account holder under the Financial Claims Scheme
- No account fees – CBA doesn’t charge fees for term deposits
- Minimum deposit – Typically $5,000 for personal accounts

The following table shows indicative rates for CBA term deposits. Note that rates can change daily and may vary based on your customer status (e.g., existing customers may receive bonus rates).

| 3 months | 3.75% | 4.00% | $5,000 |

How to Calculate Your Term Deposit Returns
The calculator above uses the following formula to determine your returns:
For simple interest (paid at maturity):
Total Interest = Principal × Rate × (Days/365)
Maturity Amount = Principal + Total Interest
For compound interest (paid periodically):
A = P × (1 + r/n)nt
Where:
- A = Maturity amount
- P = Principal amount
- r = Annual interest rate (decimal)
- n = Number of times interest is compounded per year
- t = Time the money is invested for (in years)
For example, if you deposit $50,000 at 4.50% for 12 months with quarterly interest payments:
A = 50000 × (1 + 0.045/4)4×1 = $52,308.34
Strategic Considerations for Term Deposits
-
Laddering Strategy:
Instead of putting all your funds into one term deposit, consider spreading your investment across multiple deposits with different maturity dates. This provides:
- Regular access to maturing funds
- Protection against interest rate fluctuations
- Flexibility to reinvest at potentially higher rates
Example: Divide $100,000 into five $20,000 deposits with terms of 1, 2, 3, 4, and 5 years.
-
Tax Implications:
Interest earned on term deposits is considered taxable income. Consider:
- Your marginal tax rate when calculating net returns
- Whether to have interest paid at maturity (deferred tax) or periodically
- Potential franking credits if comparing to dividend investments
-
Early Withdrawal Penalties:
CBA typically charges significant penalties for early withdrawal, which may include:
- Loss of all or part of the interest earned
- Administrative fees (typically $20-$30)
- Reduced interest rate for the period held
Always confirm the exact penalties before committing to a term deposit.
-
Inflation Protection:
With inflation running at approximately 3.6% (RBA June 2024), consider whether your term deposit rate provides a real return (rate above inflation).
Term Length Nominal Rate Inflation (3.6%) Real Return 3 months 4.00% 3.6% 0.40% 12 months 4.75% 3.6% 1.15% 24 months 4.50% 3.6% 0.90%
Comparing CBA Term Deposits to Other Investment Options
While term deposits offer security, other investment options may provide higher returns (with corresponding higher risk):
| Investment Type | Expected Return (p.a.) | Risk Level | Liquidity | Government Guarantee |
|---|---|---|---|---|
| CBA Term Deposit | 3.25% – 4.75% | Very Low | Low (locked term) | Yes (up to $250k) |
| High-Interest Savings Account | 4.00% – 5.50% | Very Low | High | Yes (up to $250k) |
| Australian Government Bonds | 3.50% – 4.25% | Low | Moderate | Yes |
| ASX 200 Index Fund | 7% – 10% (long-term avg) | Medium-High | High | No |
| Residential Property (Rent) | 3% – 5% (gross yield) | Medium | Very Low | No |

Expert Tips for Maximizing Your Term Deposit Returns
-
Monitor Rate Changes:
CBA and other banks frequently adjust term deposit rates in response to RBA cash rate changes. The calculator above lets you compare different scenarios.
-
Consider the Roll-over Option:
At maturity, you can choose to:
- Reinvest the principal + interest for another term
- Withdraw the interest and reinvest the principal
- Close the deposit and withdraw all funds
Automatic roll-over may not always be at the best available rate, so review your options carefully.
-
Use Bonus Rate Offers:
CBA occasionally offers bonus rates for:
- New customers
- Large deposits (typically over $50,000)
- Customers who hold other CBA products
- Special promotional periods
-
Combine with Offset Accounts:
If you have a home loan with CBA, consider whether keeping funds in an offset account might provide better tax-effective returns than a term deposit.
-
Diversify Across Institutions:
The $250,000 government guarantee applies per institution. For larger amounts, consider spreading deposits across multiple ADIs (Authorised Deposit-taking Institutions).
Regulatory Protection for Term Deposits
Commonwealth Bank term deposits are protected under the Australian Government’s Financial Claims Scheme (FCS). This scheme guarantees deposits up to $250,000 per account holder per institution in the unlikely event that the bank fails.
Key points about the FCS:
- Covers all deposit accounts (savings, transaction, term deposits)
- Limit of $250,000 per person per ADI
- Joint accounts are covered up to $250,000 per account holder
- Foreign currency deposits are not covered

Economic Factors Affecting Term Deposit Rates
Several macroeconomic factors influence the interest rates banks offer on term deposits:
-
Reserve Bank of Australia (RBA) Cash Rate:
The RBA’s official cash rate is the primary driver of term deposit rates. When the RBA raises rates to combat inflation, banks typically pass these increases on to depositors (though not always in full).
Current RBA cash rate: 4.35% (as of June 2024)
-
Inflation Expectations:
Banks consider expected inflation when setting term deposit rates. Higher inflation expectations generally lead to higher term deposit rates to maintain real returns for depositors.
-
Competition Between Banks:
Banks compete for deposit funds to meet their lending requirements. This competition can lead to temporary rate premiums, especially for new customers.
-
Global Economic Conditions:
International factors like US Federal Reserve rate decisions, global recession risks, and commodity prices can influence Australian term deposit rates.
-
Bank Funding Requirements:
When banks need to increase their deposit base (for example, to meet regulatory capital requirements), they may offer more attractive term deposit rates.
For current economic indicators, visit the Reserve Bank of Australia website.
Alternatives to Traditional Term Deposits
If you’re considering a term deposit but want to explore other low-risk options, consider these alternatives:
-
High-Interest Savings Accounts:

- CBA GoalSaver (up to 4.50% with conditions)
- UBank USaver (4.80% with conditions)
- ING Savings Maximiser (5.00% with conditions)
-
Cash Management Accounts:
Offer higher interest rates than standard savings accounts while maintaining some transactional functionality.
-
Government Bonds:
Australian Government Bonds (AGBs) offer fixed interest payments with terms from 1 to 30 years. They’re considered extremely low risk.
-
Capital-Guaranteed Investment Products:
Some financial institutions offer structured products that guarantee your capital while providing potential for higher returns linked to market performance.
-
Peer-to-Peer Lending:
Platforms like Ratesetter or SocietyOne offer higher returns (typically 5-8%) by lending to creditworthy borrowers, though with slightly higher risk than term deposits.
