What is a Required Minimum Distribution (RMD)?
A Required Minimum Distribution (RMD) is the minimum amount you must withdraw annually from your retirement accounts such as a 401(k) or traditional IRA once you reach a certain age.

RMD Formula Explained
The Required Minimum Distribution is calculated using a simple formula:
RMD Formula:
RMD=Distribution FactorRetirement Account Balance
What Each Term Means:
- Retirement Account Balance: Total value of your 401(k) or IRA
- Distribution Factor: IRS life expectancy factor based on age
- RMD: Minimum amount you must withdraw annually
Example Calculation
Let’s understand with a real-life example:
- Retirement Balance: $500,000
- Age: 75
- Distribution Factor: 22.9
Calculation:
RMD = 500,000 ÷ 22.9 = $21,834.06
So, you must withdraw at least $21,834.06 for that year.
