Your father is 50 years old and will retire in 10 years. He expects to live for 25 years after he retires, until he is 85. He wants a fixed retirement income that has the same purchasing power at the time he retires as $55,000 has today. (The real value of his retirement income will decline annually after he retires.)

He currently has $140,000 saved, and he expects to earn 8% annually on his savings. The data has been collected in the Microsoft Excel Online file below.
