<prompt> Human: I am looking for some help here and possibly someone to contribute a working spread sheet that could show the comparison based on an input expense ratio and load fee. I have read a lot about performance being equal over the most recent 3-5 year period, but we are looking at a little more time than that.I am looking at investing in an American Funds Roth IRA. Class A shares have a 5.75 load assessed each time money is deposited to purchase new shares, and the fund has a yearly expense ratio of 0.79. Class C shares are a no-load option, but have a yearly expense ratio of 1.39. I am in my mid 20s, and starting an account for both myself and my wife. If we hypothetically deposit our maximum contribution each year for the next 25 years, which fund would be better off?Thanks for any input. Math appreciatedEdit: Well, you have swayed me away from them fairly quickly. I was really looking at them to keep my accounts housed in one place as my 403b from work is through american funds.Assistant: I have read the side bar, I understand that most people agree to do index funds, but looking for something a little more aggressive that hopefully can outperform the market  <response>: American Funds dont outperform the market. Youre wasting your time.
