Roth Ira Conversion Calculator

A Roth IRA is one of the most powerful retirement savings tools in the United States. It allows contributions with after-tax dollars and provides tax-free growth and withdrawals during retirement. Many investors consider converting a traditional IRA or 401(k) into a Roth IRA to take advantage of tax-free withdrawals later.

However, Roth conversions involve complex calculations including taxes owed, current account balances, and future growth estimates. The Roth IRA Conversion Calculator simplifies this process, helping you make informed decisions about retirement planning.

How Roth IRA Conversion Works

A Roth conversion involves moving money from a traditional IRA or 401(k) to a Roth IRA. Key considerations include:

  1. Current Account Balance: Amount in your traditional IRA or 401(k).
  2. Current Tax Rate: Conversion is taxed as ordinary income.
  3. Future Growth: Money in a Roth grows tax-free.
  4. Time Horizon: The longer the money grows, the more beneficial the Roth conversion may be.

Conversion Formula (Plain Text):

Roth IRA Conversion Tax = Amount Converted × Current Tax Rate

Example:

  • Traditional IRA Balance: $50,000
  • Current Tax Rate: 22%
  • Tax Owed: $50,000 × 0.22 = $11,000

After conversion, your Roth IRA balance is $50,000, but you pay $11,000 in taxes upfront.

Example Calculations

Example 1: Simple Conversion

  • Traditional IRA Balance: $50,000
  • Tax Rate: 22%
  • Growth Rate: 6%
  • Years to Retirement: 20

Calculation:

  • Tax Owed = $50,000 × 0.22 = $11,000

Example 2: Larger Conversion

  • Traditional IRA Balance: $100,000
  • Tax Rate: 24%
  • Growth Rate: 7%
  • Years to Retirement: 25

Calculation:

  • Tax Owed = $100,000 × 0.24 = $24,000
  • Projected Roth Value (25 years at 7%) ≈ $540,360 (tax-free)

Example 3: Partial Conversion

  • Traditional IRA Balance: $80,000
  • Convert $40,000
  • Tax Rate: 22%
  • Growth Rate: 5%
  • Years to Retirement: 15

Calculation:

  • Tax Owed = $40,000 × 0.22 = $8,800
  • Projected Roth Value (15 years at 5%) ≈ $85,999 (tax-free)

Partial conversions allow spreading tax liabilities over several years.
