Bankrate Roth Conversion Calculator
Planning for retirement is not just about saving money—it’s about choosing the right account strategy to maximize your future wealth. One of the most important financial decisions investors face is whether to convert a traditional retirement account into a Roth IRA.
The Bankrate Roth Conversion Calculator is designed to help you estimate the future value of your retirement savings, calculate the expected tax impact of conversion, and understand how your money could grow over time. With just a few inputs, you can gain powerful insights into your long-term financial planning.
This tool is especially useful for investors, financial planners, and individuals who want to optimize tax efficiency in retirement.
What Is a Roth Conversion?
A Roth conversion is the process of moving money from a traditional retirement account (like a Traditional IRA) into a Roth IRA.
Here’s the key difference:
- Traditional IRA → Taxed when you withdraw
- Roth IRA → Taxed before conversion, tax-free withdrawals later
This calculator helps you understand:
- How much tax you might owe during conversion
- How your investment grows over time
- What your retirement value looks like after taxes

Understanding the Formula Behind the Calculator
This tool uses three main financial formulas to estimate your retirement outcome.
1. Future Value of Investment
FV=P(1+r)t
PV
$
r
%
n
PV is starting amount; r is rate; n is number of periods.
FV=PV(1+r)n=1(1+0.05)20=2653.3dollars24681012141618205001000150020002500$2,653.30
Where:
- FV = Future Value
- P = Current Balance
- r = Annual Growth Rate
- t = Time in Years
This formula calculates how your retirement savings grow over time with compound interest.
2. Estimated Tax on Conversion
Tax=P×TaxRate
Where:
- P = Current Balance
- TaxRate = Expected tax percentage
This estimates how much tax you would pay when converting to a Roth IRA.
3. After-Tax Roth Value
RothValue=P−Tax
This shows the actual amount that gets transferred into your Roth IRA after taxes.
Example Calculation
Let’s understand this with a real-world example.
Inputs:
- Current Balance = $50,000
- Tax Rate = 20%
- Years = 20
- Growth Rate = 6%
Step 1: Future Value
FV = 50,000 × (1.06)^20
FV ≈ $160,356
Step 2: Tax Calculation
Tax = 50,000 × 0.20
Tax = $10,000
Step 3: Roth Value
Roth Value = 50,000 – 10,000
Roth Value = $40,000
Final Insight:
Your $50,000 could grow to $160,356, but you would pay $10,000 in taxes upfront for Roth conversion benefits.
