Manually calculating RMDs can be confusing, but our 401(k) Mandatory Withdrawal Calculator simplifies the process, giving you accurate results in seconds.

This article will walk you through how to use the tool, provide a practical example, and explain its features, benefits, and use cases. We’ll also cover common questions to ensure you fully understand how to plan your withdrawals efficiently.

The RMD is the minimum amount the IRS requires you to withdraw from your retirement accounts each year after reaching a specific age (currently 73 as of 2026). Failing to take your RMD can result in significant penalties, making accurate calculations essential.

This calculator takes your account balance, age, and the IRS-provided life expectancy factor to quickly compute the required withdrawal and its impact on your overall portfolio.

Practical Example

Let’s see the calculator in action:

Scenario:

• Account Balance: $200,000
• Age: 75
• Life Expectancy Factor: 24.7

Calculation:

• RMD = Account Balance ÷ Life Expectancy Factor
• RMD = $200,000 ÷ 24.7 ≈ $8,097
• Annual Impact = ($8,097 ÷ $200,000) × 100 ≈ 4.05%

This means you must withdraw approximately $8,097 this year, which is 4.05% of your total account balance.
