What is AER?
AER, or Annual Equivalent Rate, is a single yearly figure showing what a savings account pays, with compounding already included. It assumes you leave the money and interest alone for a year and the rate stays put. That makes accounts comparable however often they pay interest. AER is for savings, APR is for borrowing, and APY is the same idea with a US label. But AER only measures interest: fees, withdrawal limits, tax, variable rates, temporary bonuses and conditions all sit outside of it.
