Calculating the Effective Annual Rate (EAR) | Calcblog

Details: If you deposit $1,000 in a bank account paying 10% interest compounded semiannually, this means you earn 5% every six months (two times per year) on your bank account.After one year, you would have a bank account balance of $1000 x (1 + .05) 2 = $1,102.50. Notice that this is $2.50 higher than the bank account with 10% compounded once a year.
