Since you're asking this question in the first place, you should be extremely happy if you break even after commissions, but I don't think even that's realistic. Good luck.
Forget goals of return. Just make ANY return in the first place. Consistently. Later you will improve from that level.
+1 The only thing budgets are good for is to provide guidance for the amount of risk you should be running. Too many external factors can impact your ability to hit your budget.
Generally, when one speaks of a small account, it is small cause of lack of experience. And being lack of experience means learning curve can be many years of trying to have any profit at all. HUGE difference between established traders trading/investing $20k and one just starting out. So whereas first three years you are groping along at breakeven, an experienced trader can be hitting 100%-1,000% plus till he/she starts thinking of cutting overall risk exposure back. Everyone has a number in mind at this time, either withdrawing to diversify into other wealth building entities or buying a home. Case in point, I mentor a "kid" who is very good at finding low priced stocks that going to make a run up, he buys before me but in percentage form, I always make so much more. I can't teach him to sit on his hands, some elements of trading you have to learn by pain, and it is always PAIN, pain of taking a small loss or PAIN of not making enough on winners. You want to make long term profits? I started in my early twenties, buy one rental house each year, by the time you hit early sixties, you will have over 40 rental houses and you become one heck of a repair man, you now have money coming in and you have learned a skill/hobby.
