THE PERSONAL FINANCE PODCAST
Host: Andrew Giancola
Episode: The Biggest Retirement Mistakes People Make (Avoid These!) - Jesse Cramer
Date: February 23, 2026

Episode Overview

This episode dives deep into the most common—and damaging—retirement planning mistakes. Host Andrew Giancola teams up with retirement planner and “Best Interest Blog” creator Jesse Cramer to break down why the biggest pitfalls aren’t about math, but fear, over-conservatism, and emotional decision-making. Together, they cover Social Security timing, Roth conversions, rate of return assumptions, spending in retirement, and how even planning “optimizers” can get tripped up by faulty thinking. The episode delivers grounded advice, practical examples, and a blend of technical rigor with real-life perspective.

Key Discussion Points & Insights

1. The Real Risks in Retirement Planning

• Emotional vs. Mathematical Mistakes:
  Both Andrew and Jesse stress that most retirement errors are driven by fear and emotion, rather than a failure to understand the numbers.

  • “The biggest retirement mistakes don't come from bad math. They come from fear. They come from assumptions, and they come from decisions that look right on paper but feel wrong in real life.” — Andrew (00:00)
  • Jesse notes the danger of over-conservatism: “Being overly conservative, it might make you feel safe, but it's creating risks that you might not even be aware of.” (00:09)

• The Danger of Delay:
  Some people delay retiring despite being financially ready.

  • “Year after year they have been saying they want to retire. Five years ago, they could have retired…A lot of it came down to one word, which is fear.” — Andrew (00:26)

2. Social Security: Math or Mindset? [08:23]

• The Value and Purpose of Social Security:

  • Jesse explains: “Social Security has as much value to them as their decades of retirement saving did. It needs to be treated really importantly for that reason.” (09:00)

• Break-Even Age & Longevity Insurance:

  • “If we think of Social Security as longevity insurance…you really want to delay claiming your Social Security as long as possible till age 67, 68, even 70, if you can afford to.” — Jesse (11:12)
  • The critical break-even age for delaying is often late 70s: “If, you know, you're gonna die before age 78, 79, 80, you wanna claim Social Security as early as you can. If you know you're gonna live beyond age 80, you delay.” — Jesse (12:50)

• Spousal & Survivor Considerations:

  • The higher-earning spouse should typically delay, lower-earning spouse can claim earlier. This ensures the survivor benefits get maximized.
  • “Now that's where you say, oh, when you have two people, odds are one of them is going to live to that 85, 90, 95 range and you want to have that much bigger benefit to support them.” — Jesse (16:30)

• The "Invest Early, Claim Early" Argument:
  Jesse debunks the idea of claiming early and investing the difference:

  • “By delaying your Social Security, the government is guaranteeing you a 7 or 8% higher payment for every year you delay... I like the idea of having that guaranteed 7 or 8%.” (18:09)

• Resources Mentioned:

  • Jesse recommends Mike Piper's writing (Oblivious Investor blog) and SSA.gov for personalized planning tools. (22:02)

3. Roth Conversions: When and When Not to Convert [23:30]

• Tax Rate Arbitrage:

  • “The idea is that a retiree is intentionally trying to move money from a higher tax year to a lower tax year, thereby lowering, minimizing, optimizing their lifetime tax bill.” — Jesse (23:30)
  • Roth conversions typically work best in early retirement years, when income is low pre-Social Security and pre-pension.

• Bad Roth Conversions—Real Life Stories:

  • Example 1: High-earning professional wants to convert during peak income years; it’s a mistake:
    • “She’s making [big money]; marginal taxes are the 32, 35% tax bracket…if she waits until retirement…she’s going to pay 10, 12, 22%…It was so clear, black and white.” (28:41)
  • Example 2: Retiree wants to convert $2 million at once:
    • “When you do a $2 million Roth conversion, you are effectively realizing $2 million in income all in one tax year. Any way you cut it, 1.5 of that is going to get taxed at 37%...Just spread this out over 10 years and you’ll be better off.” (28:41)

• Lesson:
  Run the math; optimal Roth conversion timing is usually early retirement or artificially low-income years (e.g. sabbatical), not during high earning phases.

4. Return Assumptions: Don't Fool Yourself [36:50]

• Nominal vs. Real Returns:

  • “When I’m thinking 20, 30, 40 years out…it’s 10% nominal, 7-ish percent real return.” — Jesse (36:50)
  • Many people confuse or double-count inflation in planning, leading to miscalculations. (40:37)

• Dangers of Over/Under-Conservatism:

  • Compound interest magnifies errors in return assumptions.
  • Jesse cautions: “If you make conservative assumptions everywhere you look, especially in this world of financial planning, not only do they add, they actually probably multiply. Your conservatism will multiply together and next thing you know…you might be postponing your actual retirement date by at least a decade.” (44:28)

• Fear-Driven Planning:

  • “Don’t you want to avoid working five extra years that you never would have had to? Don't you want to avoid this fact where you basically scrimped and saved and you didn't live the life you wanted to live?” — Jesse (48:34)

• Rate-of-Return Hype & Arithmetic vs. Geometric Mean:

  • Jesse criticizes using 12% or higher return estimates popularized by some personalities:
  • “Some personalities look at market history and just average the performance over time…arithmetic mean always gives you a larger return than the geometric mean…For our audience…teach yourself the math, understand the math, believe the math…” (52:18, 56:19)

5. Retirement Spending: What Most Get Wrong [57:15]

• Know (Really Know) Your Numbers:

  • “I'll say…very simple and 101…you need to understand going into retirement what your spending looks like. And not every retiree does that.” — Jesse (57:15)
  • Many even affluent pre-retirees are unclear on monthly spending.

• How Spending Changes in Retirement:

  • Spending usually decreases, except healthcare, which rises.
  • Younger planners should use a “range” of spending, not a single estimate, to build flexibility:
  • “Rather than picking a single specific number, instead pick a range of numbers, build that flexibility into your range of numbers, and say, here's what I'm spending now, here's what my picture-perfect retirement might look like.” — Jesse (61:40)

• Annual Check-Ins & “Turning the Dial”:

  • Andrew advises running retirement numbers annually and adjusting as life changes:
    • “Every single year you make these minor tweaks…so you don't have to like rip a band aid off 10 years down the line.” (63:11)

Notable Quotes & Memorable Moments

• On Over-Conservatism:

  • “My recommendation is to at first use only the realistic numbers. And then once you've done all your multiplication and you get to your final, final answer, only then do you add a little bit of conservatism on at the very end.” — Jesse (44:28)
  • “Being overly conservative, it might make you feel safe, but it's creating risks that you might not even be aware of.” — Jesse (50:00)
  • “It's almost like that grandpa in the left lane who's doing 50 when everyone else is doing 70…he thinks he's being conservative. He's actually creating more risk than he's aware of.” — Jesse (50:00)

• On Rate-of-Return Assumptions:

  • “For our audience…teach yourself the math, understand the math, believe the math that you're putting together, and make sure that your math reflects reality.” — Jesse (56:19)

• On Flexibility in Planning:

  • “I don't know exactly if money buys happiness, but I do know that money buys flexibility, and that usually flexibility leads to some happiness.” — Jesse (61:40)
