Should You Keep Your Traditional IRA Or Convert To A Roth IRA?

IRAs are popular retirement savings plans – but should you choose a Roth or Traditional?

This Roth vs Traditional IRA calculator will help you compare the tax and investment consequences of each option so that you can determine the best account for you.

Similarly, this Roth IRA calculator will highlight the consequences of converting from a Traditional IRA to a Roth IRA so that you can see the financial consequences and make an appropriate decision.

It simplifies all the variables and complicated math into easy-to-understand results.

IRA Overview

An IRA is an individual retirement plan – also called an individual retirement arrangement – that provides tax advantages for U.S. taxpayers saving for retirement.

IRAs are provided by many financial institutions, including some employers. Contributions are sometimes based on and limited by employment compensation, which includes wages, salaries, fees, tips, bonuses, commissions, taxable alimony, and separate maintenance payments.

Types of IRA’s include both Traditional and Roth IRAs. Each has eligibility restrictions based on your income or employment status. IRAs have contribution limits and penalties if you take out money before the pre-determined retirement age. Find the best IRA account type for you by using the Roth IRA conversion calculator above.

Differences Between Roth And Traditional IRAs

Money in Traditional and Roth IRAs grow tax-free – while the money is in the account. The type of individual retirement account you choose has a significant impact on you and your family’s long-term savings so it is important to understand the differences between Traditional and Roth IRAs:

  • Income Taxes – With a Traditional IRA, you usually get an up-front tax deduction but then have to pay the taxes when you withdraw money from your account. With a Roth IRA, it’s the exact opposite – you pay the taxes on your earned income up-front, but there are no taxes when you withdraw your savings.
  • Age Eligibility – With a Roth IRA, anybody at any age with employment compensation can sign up for an account. But for the Traditional IRA, anybody with employment compensation can sign up for an account as long as they are not older than 70 ½.
  • Income Eligibility – One factor that determines whether you should fund a Roth or Traditional IRA is your income. There is no income limit for a Traditional IRA. For the Roth IRA, your contributions may be limited for higher income earners. Check the latest IRS rules for current limits because they change regularly.
  • Distribution Rules – At the age of 70 ½, Traditional IRAs require you to start taking required minimum distributions. Roth IRAs don’t dictate withdrawals during the owner’s lifetime. Roth IRA withdrawals are tax-free and penalty-free. So, if you don’t need the money, you can leave your contributions in a Roth IRA for as long as you want. For both Traditional and Roth IRAs, owners can begin withdrawing their contributions at age 59 ½ without any penalty. However, for Traditional IRAs, distributions will be treated as ordinary income and may be subjected to an early-distribution penalty if the owner withdraws before reaching age 59 ½.
