Found this article:

It says:
How do you calculate your taxable percentage with the pro-rata rule?
- (non-deductible amount) / (total of all non-Roth IRA balances) = non-taxable percentage.
- (amount to be converted to Roth IRA) x (non-taxable percentage) = amount of after-tax funds converted to Roth IRA
In other words, "you don't get to cherry pick and only choose to convert your nondeductible contributions...because the IRS uses the IRA aggresgation rule when calculating taxes owed on a conversion, which means it views all your traditional IRAs as a single tax entity."
So let's say I make a $7,000 nondeductible IRA contribution this year and I immediately convert it to a Roth. My pre-tax traditional IRA is worth $600k, so with the nondeductible contribution it's worth $607k. The $7k is 1.1% of the total balance, meaning that 98.9% of my conversion is going to be taxable. Or $6,923. So I'm not causing myself to have to pay income tax on an extra $6,923 just so I can do a back door Roth. Makes no sense.
I knew it had to be too good to be true. So all these posters crowing about back door Roths and always making it seem like you're dumb if you don't do it either a) have no other traditional IRAs, b) don't know the rules or c) paying a whole lot of unnecessary taxes.
