What is AER?
Anya GairWhen you're looking to grow your savings, understanding the interest rates on your accounts is crucial. One term you'll often come across is the Annual Equivalent Rate (AER). But what exactly is AER, and how does it impact your savings? Let's break it down.
What is AER?
The Annual Equivalent Rate (AER) is a standardised way of showing how much interest you'll earn on your savings over a year. It takes into account whether the interest is paid monthly or yearly and how it's compounded. This makes it easier to compare different savings accounts, even if they pay interest at different times.
For example, if an account has an AER of 1%, this means that if you leave your money in the account for a year, you'll earn 1% interest, regardless of how often the interest is paid and compounded. If your interest is paid monthly, you'll receive 1/12th of the annual rate each month. The interest can then compound (earn interest on itself) throughout the year.
How does AER work?
AER works by standardising the interest you earn on your savings over a year. It accounts for the frequency of interest payments (monthly, quarterly, annually) and the compounding effect of those payments. This allows for a more straightforward comparison between different savings accounts.
How to calculate AER?
To calculate AER you need to follow these steps:
- Divide the interest rate on the account by the number of times a year that interest is paid (compounded) and add 1.
- Multiply the result to the number of times a year that interest is paid (compounded).
- Subtract 1 from the subsequent result. AER is then displayed as a percentage (%)

What is AER variable?
AER variable means that the interest rate on your savings account can change over time. Banks may adjust the rate based on market conditions or other factors. When you see "variable" associated with AER, it indicates that the rate isn't fixed and could go up or down.

What is AER fixed?
AER fixed means that the interest rate on your savings account is locked in for a specific period - normally between 1-5 years/ You'll know exactly how much interest you'll earn, regardless of changes in the market. This can be advantageous if you want predictable returns on your savings.
AER vs. Gross Interest
AER and gross interest are related but not the same. Gross interest is the nominal rate of interest you're paid before any tax deductions or compounding effect. AER, on the other hand, takes into account the effect of compounding interest over the year, providing a more accurate representation of annual earnings on your savings.
What is a good AER rate?
Generally, a higher AER signifies better potential earnings on your savings, but it's important to consider other factors such as account fees, minimum balance requirements, and the stability of the interest rate. For typical savings accounts, an AER of around 2-3% might be considered competitive, while promotional offers could offer rates of 4% or higher. It's always good to compare different accounts and read the fine print to ensure there are no hidden conditions that could impact your overall returns, such as the rate changing after the first year.
Conclusion
Understanding AER can significantly impact how you choose to save your money. By knowing how much interest you'll earn and how it's calculated, you can make more informed decisions and ultimately grow your savings more effectively.
