1. What is the Roth Conversion Benefit?

The Roth Conversion Benefit calculation helps determine whether converting a traditional IRA to a Roth IRA makes financial sense by comparing the tax implications of paying taxes now versus paying taxes later.

2. How Does the Calculator Work?

The calculator uses the Roth Conversion formula:

Where:

• \( Future\ Growth \) — Expected growth of the investment (USD)
• \( Tax\ Now \) — Current tax rate as a decimal (unitless)
• \( Tax\ Later \) — Expected future tax rate as a decimal (unitless)

Explanation: A positive benefit indicates that converting to a Roth IRA may be advantageous, while a negative benefit suggests keeping the traditional IRA may be better.

3. Importance of Roth Conversion

Details: Roth conversions can provide tax-free growth and withdrawals in retirement, required minimum distribution (RMD) flexibility, and potential estate planning benefits.

4. Using the Calculator

Tips: Enter future growth in USD, tax rates as decimals between 0 and 1 (e.g., 0.25 for 25%). All values must be valid (future growth > 0, tax rates between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: When does a Roth conversion make sense?
A: When you expect to be in a higher tax bracket in retirement, want to avoid RMDs, or want to leave tax-free assets to heirs.

Q2: What are the tax implications of a Roth conversion?
A: The converted amount is taxable income in the year of conversion, but future qualified withdrawals are tax-free.

Q3: How do I estimate my future tax rate?
A: Consider expected retirement income, tax law changes, and your withdrawal strategy. Consult a tax professional for complex situations.

Q4: Are there limitations to this calculation?
A: This is a simplified model. Real-world decisions should also consider current vs. future tax brackets, time horizon, and other assets.

Q5: Can I undo a Roth conversion?
A: Recharacterizations of Roth conversions are no longer allowed under current tax law (after 2017).
