Let’s think of it another way so that we can see the impact of compounding on this investment. For simplicity’s sake, we’ll assume that Adrian’s rate of return is effectively 5.7% annually (7% - 1.3% fee) and Clemens’s rate is effectively 6.8% annually (7% - 0.2% fee). Each man contributes an additional $100/month into their investment account. Use the compound interest calculator to answer these questions. You can round to the nearest whole dollar and assume the investment compounds annually.
