When Can I Retire Pro

 
This unique app calculates your retirement age by separating out your retirement savings in taxable accounts (cash, investments) and tax-advantaged accounts (Traditional, Roth) as certain tax-advantaged retirement savings cannot be withdrawn without a penalty until you reach the age of 59 1/2.

This app helps you with an effective strategy on the order in which you can withdraw your retirement assets during your retirement years when you have savings in taxable, tax-deferred, and tax-free accounts. The retirement withdrawals are made first from your taxable accounts, then from your tax-deferred accounts, and finally from your tax-free accounts.

The app lays out a clear picture of your finances with a pre-retirement plan and a post-retirement plan.

You can download this app from Apple Store.
