The Required minimum distribution method is a simple way of calculating substantially equal periodic payments and is one that resets every year. It is basically calculated by dividing your retirement account balance by your life expectancy factor as provided by the IRS grid.
You will have three choices for a life expectancy factor. You can either go with single life expectancy(no beneficiary), joint life expectancy, or the Uniform Lifetime table. The latter two assume a beneficiary. Remember, the longer you expect to have to pay benefits, the smaller your payments will be.
First you need to determine what your account balance is. The IRS does not provide guidelines on this except by saying that the balance must be determined in a reasonable manner. The most prudent thing to do here would be to use the balance of your account from the end of the prior tax year.
Now that you have your balance, you will divide this by the life expectancy factor that you derived from one of the three life expectancy tables we mentioned above. This is the amount you will receive in the first year.
This process must be repeated every year and be sure to only distribute the exact amount that you calculated.
Being that you will be receiving an adjusted amount every year, this method allows you to actually withdraw an amount which takes into account your gains/losses from the prior year.
The drawback to using this method is probably obvious to you now. Your distributions could swing drastically up and down as your investments fluctuate. If you are looking for stable payments every year, this may not be the best option. The nature of the life expectancy table renders smaller payments upfront and larger payments as you approach retirement. This could be troubling for some of you as well.
It is a big step to decide which form of computation you will be using to determing periodic payments; it is advisable to seek the help of a professional before you make the final move.
Just a few other rules to know about when it comes to required minimum distributions.
