The Paper-Perfect Retirement Trap
You can follow all the classic retirement advice—delaying Social Security, systematically converting to a Roth IRA, and sticking to the 4% rule—and still end up with a financial plan that harms your household cash flow.
In this interview, Robert Powell, CFP®, sits down with Jae Oh, CFP®, author of “Maximize Your Medicare” and “Maximize Your Retirement” and fellow at LIMRA’s Retirement Income Institute, to discuss his research examining more than 300 combinations of retirement planning approaches. They explore why decisions that seem mathematically optimal in isolation frequently backfire when combined, and how retirees can stress-test their plans against real-world friction.

Key Takeaways
- No Universal Winner: Across 300+ modeled planning variations, no single withdrawal rate or claiming method consistently minimized the burden on savings; optimal strategy is strictly dictated by household-level friction.
- The Interaction Effect: Accelerating income for a Roth conversion might look brilliant on a federal tax schedule, but the resulting surge in MAGI can trigger Medicare IRMAA surcharges or eliminate pre-65 ACA health subsidies.
- Test the Ripple: Never evaluate a Social Security or investment decision in isolation. Always ask: “If we execute this move, which specific account does next month’s spending cash come from, and what tax bracket does it hit?”
