The first step is to multiply the present value by the interest rate. Since the present value is $1.6 million and the interest rate is 10%, this yields. $160,000. This product is then divided by 1 - (1 + the rate)^-term. So it is divided by 1 - (1.1)^-15. That is, the annual payment = $160,000/[1 - 1.1^-15] = $160,000/.760607951= $210,358.04
