The short answer is that you should invest whatever you can afford to lose.
Here is a more detailed answer. Way too often, people jump in with both feet and end up digging a financial hole for themselves because they think that the more money they pour in, the more money will come out. While the size of your investment directly affects your ability to make money, be careful not to allow your investment to cause you to miss a meal.
Set aside a certain amount of money each month that you know you can do without and build from there. If you can afford a standing order, purchasing 125 TCredits ($36.35) is the best way to maintain your EA rank, but if you are not able to invest that much right now, save your money and work on selling products instead.
Either way, you should be saving more money than you invest so a portion of your money will build up every month. For example, if you have a standing order for $36.25, set aside $40 so you can save $3.75 every month. After 12 months passed, you will end up with $45 on top of the money for the standing order that month!
In addition to saving money every month, you will also be earning commissions along the way. Don't spend your commissions outside of SFI and you will be able to use that money for your standing order too. That will help you build a nice cushion for future purchases should you find yourself needing to reduce your personal investment for a while.
