A B C D E F G H I L M N O P R S T U

A

AER Money: Annual Equivalent Rate. The interest rate on a savings account expressed as a single annual figure, including the effect of compounding. Used to compare savings products on a like-for-like basis. A 4.5% AER product genuinely returns 4.5% over a year if rates don't change.
