AER stands for 'Annual Equivalent Rate'. It's the official rate for savings accounts and allows you to easily compare savings accounts. It is designed to show you what you would get over a year if you put money in the account and left it there. 

I first found out about them over 10 years ago and immediately knew I wanted to be part of it. By becoming a member I know my savings are only going to directly help people and local enterprises in my own community.
