Roth IRA Tools About Roth IRA Tools
Roth IRA Tools is an independent site built and maintained by one person. It covers one subject: how much you are allowed to put into a Roth IRA, and how that amount is calculated when your income falls inside the phase-out range.
Who runs this site
My name is Xiong Jin. I am an independent developer. I am not a financial advisor, I do not have a firm behind me, and no one pays me to say a number is correct.
I write the code, I read the IRS publications, and I check the figures myself.
What this site does differently
Most Roth IRA calculators stop at the straight-line phase-out math. The IRS worksheet does not. Publication 590-A, Worksheet 2-2, rounds the reduced amount up to the nearest $10 and applies a $200 minimum in two specific cases — which means that for someone near the top of the income range, the two methods can differ by several hundred dollars.
I built this site around that difference. Every calculator here follows the worksheet, cites the line it implements, and tells you when the result is an estimate rather than a match.
Where the numbers come from
Every contribution limit and income range on this site is taken from the IRS announcement that established it, and each page links to that announcement. When a new tax year's figures are released, generally in November, I update the data, re-run the test cases against the IRS worksheet, and change the "last verified" date on the pages affected.
I do not publish projected figures before the IRS releases them. If you see a number on this site, it came from the IRS, not from an estimate of what the IRS might do.
If a figure here ever disagrees with the IRS worksheet, the worksheet is right. Email me at support@rothiratools.com and I will fix it.
What this site is not
This site does not provide personalized financial, tax, or investment advice, and nothing on it should be read as a recommendation to open, fund, or transfer any account.
It also does not know your full situation. The calculators apply the income phase-out, but they do not cap your contribution at your taxable compensation, and they do not subtract contributions you make to other IRAs for the same year. If either applies to you, your actual limit will be lower than the number shown.
