If you’ve recently inherited a Roth IRA, understanding your Required Minimum Distributions (RMDs) is crucial to comply with IRS rules and maximize your retirement benefits. Our Inherited Roth IRA RMD Calculator is designed to simplify this often confusing process by providing you with clear, accurate calculations based on your unique situation.
Inherited Roth IRA RMD Calculator
What is an Inherited Roth IRA RMD Calculator?
When you inherit a Roth IRA, the IRS requires you to withdraw a certain amount each year—known as Required Minimum Distributions. However, the rules for these distributions depend on several factors, including your age and whether you choose the 10-year withdrawal rule or the life expectancy method.
Our Inherited Roth IRA RMD Calculator helps you determine the minimum amount you must withdraw annually from an inherited Roth IRA based on:
- The account balance at the time of inheritance
- The distribution method you select (10-Year Rule or Life Expectancy Method)
- Your age (if using the Life Expectancy Method)
Using this calculator ensures you stay compliant and helps you plan your withdrawals to optimize tax benefits.
How to Use the Inherited Roth IRA RMD Calculator — Step by Step
Step 1: Enter the Account Balance
Start by inputting the total balance of the inherited Roth IRA. This should reflect the account value as of the end of the previous year or the date you inherited the account.
Step 2: Choose the Distribution Method
There are two IRS-approved methods for taking RMDs from an inherited Roth IRA:
- 10-Year Rule: You must fully withdraw the entire account within 10 years following the original owner’s death. This method divides the balance into equal annual withdrawals over 10 years.
- Life Expectancy Method: This method spreads the distributions over the beneficiary’s remaining life expectancy, calculated using IRS Single Life Expectancy Tables.
Select the method that applies to your situation.
Step 3: Enter Beneficiary Age (If Applicable)
If you selected the Life Expectancy Method, enter your age in the year following the original owner’s death. This helps calculate the appropriate divisor for your RMD.
If you chose the 10-Year Rule, this field is hidden because age is irrelevant in that method.
Step 4: Click “Calculate”
Hit the calculate button to view:
- The distribution method selected
- The total distribution period in years
- The first-year RMD amount
- The suggested equal annual withdrawal (for 10-year rule)
Step 5: Review Your Results
The results panel will display your RMD figures clearly. If you chose the life expectancy method, a note explains that the divisor decreases by one each subsequent year.
Practical Examples
Example 1: Using the 10-Year Rule
Scenario: You inherited a Roth IRA with a balance of $100,000 and opted for the 10-year rule.
- The calculator divides $100,000 by 10 years.
- Your annual RMD is $10,000 each year for 10 years.
Example 2: Using the Life Expectancy Method
Scenario: You inherited a Roth IRA worth $100,000. You are 50 years old in the year following the owner’s death.
- The IRS Single Life Table factor for age 50 is approximately 34.2.
- First-year RMD = $100,000 ÷ 34.2 ≈ $2,923.
- Each subsequent year, the divisor decreases by 1, increasing the RMD accordingly.
Why Use This Calculator?
- Avoid IRS penalties: Failing to take the proper RMD results in a hefty 50% penalty on the missed amount.
- Tax planning: While Roth IRA withdrawals are generally tax-free, understanding your distribution schedule helps manage estate planning and cash flow.
- Ease of use: No need for manual IRS table lookups or complicated formulas.
- Stay informed: Keep track of the exact withdrawal amount every year based on updated balances and age.
Additional Tips and Use Cases
- Plan early: Calculate your RMDs as soon as you inherit the Roth IRA to avoid last-minute tax surprises.
- Reinvest excess distributions: While you must withdraw the minimum, you can withdraw more and reinvest elsewhere if needed.
- Consult a tax advisor: RMD rules can vary with recent legislation (e.g., SECURE Act changes). Professional advice is recommended for complex estates.
- Use the Life Expectancy Method if you want to stretch distributions and reduce annual taxable income elsewhere.
