What is the minimum withdrawal from an IRA?

The minimum withdrawal from an IRA is based on the balance at the end of the previous calendar year divided by a figure outlined in the IRS "Uniform Lifetime Table" distribution period. This table is available online on the IRS website, according to the IRS.

Account holders with traditional IRA accounts must start withdrawing from their accounts in the year they turn 70 1/2, as reported by CNN Money. However, Roth IRA account holders may leave the money in the account indefinitely. The amount that traditional IRA account holders must withdraw is called the required minimum distribution (RMD). The RMD can vary depending on the amount saved and the life expectancy of the account holder.
