    For simple interest, and compounded yearly, at the end of one year, the interest is the same, as there is only one period.
    interest rate = 1.03
    Balance = PRN = 1000*1.03*1 = $1030
    Interest = balance - principal = 1030-1000=$30

    Principal = P = $1000

    Compound interest
    Compounded annually:
    balance = PRn = 1000*1.03^1 = $1030
    Interest = 1030-1000=$30

    Compounded quarterly:
    n = 12months/3months = 4
    R = 1+0.03/4 = 1.0075
    balance after 1 year
    = PR^n
    interest = PR^n-P

    Compounded daily:
    n=365
    R=1+0.03/365
    balance after 1 year
    = PR^n
    interest = PR^n-P
