Planning for retirement involves making important decisions about how and when to access your savings. One strategy many retirement savers consider is converting a traditional IRA into a Roth IRA. A Roth conversion can provide potential tax advantages because qualified Roth IRA withdrawals in retirement are generally tax-free. However, converting retirement funds from a traditional IRA to a Roth IRA may create an immediate tax obligation.
Bankrate Roth Conversion Calculator
The Bankrate Roth Conversion Calculator helps estimate the possible financial impact of converting a traditional IRA into a Roth IRA. By entering information such as your current IRA balance, current tax rate, expected future tax rate, annual investment growth rate, and years until withdrawal, you can estimate conversion taxes, future Roth IRA value, after-tax traditional IRA value, and potential tax savings.
Understanding the difference between traditional and Roth retirement accounts is essential before making a conversion decision. A traditional IRA typically allows tax-deferred growth, meaning taxes are paid when money is withdrawn. A Roth IRA works differently because taxes are generally paid before contributions or conversions, allowing qualified future withdrawals to potentially be tax-free.
A Roth conversion may be beneficial for some individuals, especially those who expect their future tax rate to be higher or who want more tax flexibility during retirement. However, the decision depends on several personal factors, including income, retirement timeline, tax situation, and long-term financial goals.
This calculator provides an estimate to help you compare potential outcomes and understand how taxes and investment growth can affect your retirement savings.
What Is a Roth Conversion?
A Roth conversion is the process of moving money from a traditional IRA into a Roth IRA. Since traditional IRA contributions are often made with pre-tax money, the amount converted is generally treated as taxable income in the year of conversion.
For example, if you convert $50,000 from a traditional IRA and your applicable tax rate is 22%, the estimated conversion tax would be:
$50,000 × 22% = $11,000
After paying the required taxes, the converted amount can grow inside the Roth IRA. If withdrawal rules are satisfied, qualified withdrawals may not be subject to federal income taxes.
A Roth conversion does not eliminate taxes completely. Instead, it changes when taxes are paid. You pay taxes now instead of potentially paying taxes later when withdrawing funds from a traditional IRA.
How to Use the Bankrate Roth Conversion Calculator
Using the calculator is simple. Enter your retirement information into each field to estimate your potential conversion results.
Step 1: Enter Your Traditional IRA Balance
Start by entering the current value of your traditional IRA.
Example:
- Traditional IRA Balance: $100,000
This represents the amount you are considering converting into a Roth IRA.
Step 2: Enter Your Current Tax Rate
Enter your current income tax rate as a percentage.
Example:
- Current Tax Rate: 22%
This rate is used to estimate the taxes due when completing the Roth conversion.
Step 3: Enter Your Expected Future Tax Rate
Enter the tax rate you expect to pay when withdrawing retirement funds in the future.
Example:
- Future Tax Rate: 25%
Your future tax rate can affect whether paying taxes now through a Roth conversion may provide benefits.
Step 4: Add Your Expected Annual Growth Rate
Enter your estimated yearly investment growth rate.
Example:
- Annual Growth Rate: 7%
Investment returns are not guaranteed, but this estimate helps calculate how your retirement account may grow over time.
Step 5: Enter Years Until Withdrawal
Enter the number of years before you expect to use the retirement money.
Example:
- Years Until Withdrawal: 20 years
A longer investment period allows compound growth to have a greater impact.
Step 6: Enter Conversion Tax Payment Method
The calculator includes an option for the percentage of conversion taxes paid directly from the IRA.
If taxes are paid from outside funds, more money remains invested in the Roth IRA.
Example:
- Conversion Tax Paid From IRA: 0%
If you use retirement funds to pay taxes, the amount invested after conversion may be reduced.
Roth Conversion Calculator Formula Explained
The calculator uses several financial formulas to estimate the results.
1. Conversion Tax Calculation
The estimated tax due on the conversion is calculated as:
Conversion Tax = Traditional IRA Balance × Current Tax Rate
Example:
Traditional IRA Balance = $100,000
Current Tax Rate = 22%
Conversion Tax:
$100,000 × 0.22 = $22,000
The estimated tax due would be $22,000.
2. Tax Paid From IRA Calculation
If some conversion taxes are paid directly from retirement funds, the calculator adjusts the amount invested.
Formula:
IRA Tax Payment = Conversion Tax × Percentage Paid From IRA
Example:
Conversion Tax = $22,000
Tax Paid From IRA = 50%
$22,000 × 0.50 = $11,000
3. Roth IRA Starting Amount
The amount invested into the Roth IRA after paying conversion taxes from the account is:
Roth Starting Amount = IRA Balance − Taxes Paid From IRA
Example:
IRA Balance = $100,000
Taxes Paid From IRA = $11,000
Roth Starting Amount:
$100,000 − $11,000 = $89,000
4. Future Roth IRA Value Formula
The future value calculation uses compound growth:
Future Value = Starting Amount × (1 + Growth Rate)ᵀⁱᵐᵉ
Where:
- Starting Amount = Initial Roth IRA investment
- Growth Rate = Expected annual return
- Time = Number of years
Example:
$100,000 × (1.07)²⁰
The result estimates future account growth.
5. Future Traditional IRA After-Tax Value
The calculator estimates the traditional IRA value after future taxes:
Future After-Tax Value = Future IRA Value × (1 − Future Tax Rate)
Example:
Future IRA Value = $386,968
Future Tax Rate = 25%
After-tax value:
$386,968 × 0.75 = $290,226
6. Potential Tax Savings
The calculator compares the Roth IRA value with the after-tax traditional IRA value.
Formula:
Potential Tax Savings = Roth IRA Value − Traditional IRA After-Tax Value
A positive result indicates that the Roth conversion may provide a higher estimated after-tax value based on the assumptions entered.
Roth Conversion Example
Consider an investor with the following information:
| Category | Amount |
|---|---|
| Traditional IRA Balance | $100,000 |
| Current Tax Rate | 22% |
| Future Tax Rate | 25% |
| Annual Growth Rate | 7% |
| Investment Period | 20 Years |
| Taxes Paid From IRA | 0% |
Step 1: Calculate Conversion Tax
$100,000 × 22%
= $22,000
The estimated conversion tax is $22,000.
Step 2: Calculate Roth Growth
Because taxes are paid separately, the full $100,000 is invested in the Roth IRA.
After 20 years at 7% annual growth:
Approximately:
$386,968
Step 3: Compare Traditional IRA
Traditional IRA future value:
Approximately:
$386,968
After 25% future taxes:
$386,968 × 75%
= $290,226
Step 4: Compare Results
| Account Type | Estimated Value |
|---|---|
| Roth IRA | $386,968 |
| Traditional IRA After Taxes | $290,226 |
| Difference | $96,742 |
This example shows how paying taxes earlier may create a different long-term outcome depending on future tax rates and investment growth.

Factors That Can Affect Roth Conversion Results
A Roth conversion decision depends on more than just account balance. Several factors can influence whether a conversion fits your retirement strategy.
Current Income Level
A large conversion may increase taxable income for the year. Some individuals choose smaller conversions spread across multiple years to manage tax impact.
Future Tax Rates
If tax rates increase in the future, paying taxes earlier through a Roth conversion may become more attractive. However, future tax laws and personal income levels can change.
Time Until Retirement
A longer time horizon allows more opportunity for tax-free growth inside a Roth IRA.
Ability to Pay Conversion Taxes Separately
Using outside funds to pay conversion taxes generally allows more money to remain invested.
Retirement Withdrawal Plans
Your expected retirement income, spending needs, and withdrawal strategy can influence whether Roth assets provide value.

Tips for Planning a Roth Conversion
Consider Partial Conversions
Instead of converting your entire IRA at once, converting smaller amounts over several years may help manage taxable income.
Review Your Tax Situation
Tax brackets, deductions, credits, and income sources can affect conversion costs.
Consider Retirement Timing
People with lower taxable income before retirement may have opportunities to complete conversions at lower tax rates.
Keep Emergency Funds Available
Conversion taxes should be planned carefully to avoid creating financial stress.
Consult a Professional
A financial advisor or tax professional can help evaluate how a Roth conversion fits your overall retirement plan.
Common Roth Conversion Mistakes to Avoid
Converting Too Much at Once
A large conversion may push income into a higher tax bracket.
Ignoring State Taxes
State income taxes may also apply depending on where you live.
Paying Taxes With Retirement Funds
Using IRA funds to pay taxes reduces the amount available for future growth.
Forgetting Long-Term Goals
A Roth conversion should fit your complete retirement strategy rather than being based only on potential tax savings.
