A 4% savings account sounds pretty attractive, but the percentage becomes much more useful when it gets translated into actual dollars. Put $5,000 in an account paying a 4% APY and leave it there for a full year, and the account would earn about $200 in interest, assuming the rate stays unchanged and the balance remains untouched.
