Read up on return of contributions - note that you must take the earnings or losses with the withdrawal.
I suspect in your example, to get $5500 back, you'd actually withdraw ~$5041 of contributions, and your 9% gain would be the other. Then yes, I you could put $5041 into the traditional IRA.
No, this is completely wrong. When you withdraw money from a Roth IRA, it is always accounted for as saying you withdraw your contributions first. So in the OP's example, the OP would only withdraw contributions, not earnings.EDIT: Sorry dandrac, I read too quickly and didn't realize you were talking about return of contributions, which are different from withdrawals.
Additionally, in the example the OP provide, OP cannot put $5041 in the traditional IRA in the same year. In fact the OP cannot put any money into a traditional IRA in that year.
Did you guys completely ignore what I said earlier?
No, because the contribution limit for IRAs is $5500 combined across all of your IRA's, whether they are Roth or traditional, or held at as many custodians as you would like.
Once you've contributed $5500 to any IRA, that's it for the year. You've filled your contribution limit for the year. You cannot contribute $5500 to a Roth IRA and $5500 to a traditional IRA in the same year.
