Most people have no idea how much money should stay in their IRA by age 72.
And that one number can dramatically impact:
• your taxes in retirement
• your Social Security taxation
• your Medicare premiums
• and how much income you actually keep
David McKnight calls it your “Magic Number” — the ideal IRA balance designed to potentially maximize retirement withdrawals while minimizing taxes.*
Knowing this number can help you better understand:
✔ Roth conversion opportunities
✔ Tax-efficient retirement planning
✔ How to potentially move closer to the 0% tax bracket in retirement
