The short answer to this question is [I]yes.[/I]
Nobody who trades for a living is going to discuss his/her personal finances with strangers, publicly here on the internet, or even privately. So, you will have to be content with general answers to your questions about trading capital, earnings and budgeting.
That being said, you have asked two related questions, which I will paraphrase as follows:
How do you budget monthly expenses, given a fluctuating income stream from trading?
How much trading capital is required to support a given lifestyle?
It’s apparent from your post that you are thinking ahead to the time when you can live comfortably on the profits from full-time trading. So, let’s talk in terms of [I]your[/I] income requirements, [I]your[/I] ability to earn profits trading this market, and [I]your[/I] capital requirements.
I see from your post history that you came to the Babypips forum 3 years ago with several years of forex trading experience behind you. Therefore, we should be able to skip over the newby basics, and cut to the chase.
With your years of trading experience, you should have a pretty good feel for your ability to earn a consistent, average, monthly ROI (return on investment) — that is, an average monthly trading profit which is a consistent percentage of the balance in your trading account.
This whole discussion will depend on those two words, [I]consistent[/I] and [I]average.[/I]
Let’s start with the question about required trading capital.
If you are able to earn an ROI of x-percent, and if you are able to maintain (or increase) that ROI as your trading account grows and all the numbers become larger, then you can easily calculate the capital required to generate a given income stream.
Let’s run through a hypothetical analysis. Then you can play with the numbers, adjust them to suit yourself, and determine whether trading for a living would really fit your temperament and fulfill your goals.
Let’s say that you need $4,000 per month in gross income (before taxes) in order to support a reasonable lifestyle and make full-time trading worth the effort and risk. And let’s say that you want this income level to grow over time, which means that you want your account balance to grow over time. Accordingly, you decide to withdraw 2/3 of your profits each month, and leave 1/3 of your profits on deposit in your account in order to grow the account.
Finally, let’s say that you have a proven track record earning x-percent average ROI per month.
We can now write an equation for C, the trading capital you need, as a function of x, your proven ROI.
C = $4,000 / [(x)(2/3)]
which simplifies to
C = $6,000 / x
where x is monthly ROI expressed as a decimal (i.e., if ROI = 1% per month, then x = 0.01)
If ROI = 1%, then x = 0.01, and C = $600,000
If ROI = 2%, then x = 0.02, and C = $300,000
If ROI = 3%, then x = 0.03, and C = $200,000
If ROI = 4%, then x = 0.04, and C = $150,000
If ROI = 5%, then x = 0.05, and C = $120,000
If ROI = 6%, then x = 0.06, and C = $100,000
You may be surprised that it takes so much trading capital to support an average lifestyle. The best star-traders may be able to achieve and maintain ROI’s that are much higher than the numbers we worked with above — and those traders can obviously generate larger income streams trading smaller accounts more aggressively than the examples given above. But, for mere mortals, like ourselves, huge ROI’s simply aren’t sustainable over the long term.
Determining whether trading for a living is feasible for you will depend on how honestly and accurately you determine (1) your true income requirements, and (2) the monthly ROI you can actually achieve and maintain over the long haul.
If you start to underestimate your income requirements, and/or overestimate the ROI you can achieve, in order to make your required capital appear more obtainable, you will be setting yourself up for trouble.
Finally, your question about budgeting should answer itself, given our assumption of a consistent, average monthly ROI in your trading account, and given the fact that the trading capital in your account will be somewhere between 25 times and 150 times the amount of your monthly withdrawals.
