NerdWallet Roth Conversion Calculator

NerdWallet's Roth conversion calculator runs the numbers on a specific decision: convert a pre-tax account to a Roth, pay taxes this year, and let the money grow tax-free forever. The tool estimates how much you'll owe in federal taxes on the conversion, projects your Roth balance at retirement, and compares the net long-term benefit against staying in the pre-tax account. This matters for people in a low-income year or those with substantial pre-tax balances they want to reposition.
It's built for people who've heard that Roth conversions can be valuable but want the numbers before deciding. The calculator lets you model different conversion amounts, so you can find the sweet spot where you're in a good tax bracket without going overboard. If you're in early retirement, taking a sabbatical, or had a low-income year, this tool justifies the conversation with a tax pro.
