IRA Calculator
Compare Traditional vs Roth IRA after-tax values with tax savings reinvestment analysis and feature comparison.

What IRA Calculator does
An IRA calculator that lets users compare Traditional and Roth individual retirement accounts side by side. By entering current age, retirement age, current balance, annual contribution amount, expected return rate, current tax rate, and retirement tax rate, the tool projects the after-tax value of each account type at retirement. The output demonstrates how pre-tax versus post-tax savings strategies affect final wealth, helping users visualize the long-term tax impact of their contribution choices. The site also includes a feature comparison of IRA types and an analysis of after-tax values with tax savings reinvestment. The page highlights a common oversight: two accounts can show identical gross balances while offering very different after-tax outcomes depending on when taxes are paid.

IRA Calculator FAQ
- Can I compare more than two IRA types at once?
- The tool is designed to compare Traditional and Roth IRAs side by side. For other account types like SIMPLE or SEP IRAs, you would need to use separate calculations or consult the site's feature comparison section for those specific arrangements.
- What if I don't know my future tax rate in retirement?
- You can experiment with different retirement tax rate scenarios. The calculator shows how changing this single variable affects the after-tax outcome, helping you understand the sensitivity of your results to tax assumptions.
- Does the calculator include employer matching or catch-up contributions?
- No, the tool focuses on individual contribution limits and does not include employer matching, catch-up contributions for those over 50, or income-based phase-out ranges.
- Are the results adjusted for inflation?
- No, the calculator provides nominal dollar amounts without inflation adjustment. To see real purchasing power, you would need to apply an inflation discount to the final projected balance.
