The way I save money, is by paying myself first. I have automatic deductions come out of my bank account on the 15th and 30th of every month, which I put directly into a mutual fund for safe keeping. I take a small portion of my pay check, roughly 10% and put it away. This may not seem like much, but over time it adds up. In addition, with mutual funds you will have the benefit of compound interest on your side. You should EASILY be able to achieve 8% interest on average in a good a mutual fund, often times more. That's $800 a year on $10000!
Professional management: You work with your adviser to build your investment plan and determine your asset allocation. When it's time to put your plan into action, you rely on a professional manager to pick the investments, monitor your portfolio and rebalance as required. This is like taking a chauffeur-driven car. You choose where to get on and off and you can also pick the route, but the actual driving and day-to-day maintenance is done by someone else.
So, you need to charge almost 4 times what you would earn in salary to end up at the same place. Don't be discouraged, there are many people out there that are charging a lot more than this and getting all the business they can handle. Remember, these numbers are hypothetical, your situation may be much different.
