Please note the following important information regarding any Roth conversion
  • Ordinary income tax is applicable on the converted amount.
  • You will not realize the full benefit of the tax-free contribution if you use your existing traditional IRA to pay these taxes.
  • If you are below 59 and 1/2, you are subject to federal and state tax penalty if you withdraw funds from the existing IRA to pay these taxes.
  • People, who are in lower tax bracket, will not be eligible for tax free contribution in Roth IRA.
  • Tax free Roth IRA distributions are available only for 5 tax years. Also, tax free withdrawals are applicable after age 59 and 1/2, for death, disability, or first time home purchase.
Amount to convert
Amount of money you are planning to transfer from the traditional IRA to the Roth IRA. It is assumed that, related conversion taxes will be paid by out-of-pocket cost. If your age is below 59 and 1/2, and if you don’t roll over any amount of money directly to the Roth IRA account, the IRS will consider it as an early withdrawal.
Non-deductible contributions
Amount of after-tax contribution you made so far in you traditional IRAs and any accounts sponsored by the employer. But you can’t selectively choose what type of fund (pre-tax or after-tax) you will convert to Roth IRAs. Rather, you will have to convert a pro-rated amount of money from both the pre-tax and after-tax contribution.
Current age
Your current age. Note that, your age must be less than 70 as the calculator does not calculate for RMD withdrawals which begins at the age of 70 and 1/2.
Age at retirement
What your age will be at the time of retirement.
Rate of return
Your expected percentage rate of return from the IRA. OkCalculator will compound this rate annually.
Current tax rate
Marginal rate of tax applicable to the Roth IRA conversion. This may not be the marginal rate you were charged so far because the conversion may lead you to a higher income tax bracket. For further details and updated information, visit
Tax rate at retirement
Your expected rate of marginal tax on income at the time you will retire.
Investment tax rate
Your expected rate of marginal tax on investments, based on your expected rate of capital gain. This rate will be used by this calculator to find out your annual return from the taxable investments. This can be the same as your current income tax rate if your non-IRA investments are made by dividends or capital gains from long-term investments.
