Your client Tom, age 45, is getting nervous about the market. He’s a moderate investor and estimates he will earn around 6% per year on his investments. His IRA currently has $100,000. Tom is considering lowering his risk tolerance to a more conservative model, which he estimates will earn him only 4% annually. If Tom decides to lower his risk tolerance from now until he retires at age 65, how much less money is he expected to have than if he kept a moderate risk tolerance?
