The 90% Retirement Rule No One Explains (Until It’s Too Late)

Video Overview & Insights

Most people think retirement success comes down to one number: your probability of success.

Why don't the models include the adjustments in the plan and include those in the probability of success? The flat line models sound like something a high school student could write.

— @brianandcindy1

If your financial plan shows an 80% or 90% success rate, it sounds like you’re in great shape. But what does that number actually mean—and more importantly, what does it not tell you?

In this video, we break down one of the biggest misconceptions in retirement planning: why a high probability of success does not guarantee a comfortable or stress-free retirement. Using insights from leading researchers like Michael Kitces, David Blanchett, and William Sharpe, we explore how modern retirement income strategies are shifting away from simple pass/fail metrics and toward something much more important—the actual experience of retirement.

Erin , love your videos, but I especially love your bloopers at the end! Thanks for another gem of a show! 🥰

— @Avianna-z2f

You’ll learn how traditional Monte Carlo simulations work, what “success” really means in a retirement plan, and why many investors may be under-spending in retirement in an effort to avoid running out of money. We also walk through how spending flexibility, withdrawal strategies, and income stability can dramatically impact your quality of life—even when two retirees have the exact same portfolio and success rate.

This video covers key retirement planning concepts including:

Oh, by the way. You're looking good Erin.

• Probability of success in retirement explained

• Monte Carlo simulation retirement planning

I honestly think most of it is phycological. You go to work mostly five days a week, and at the end of that work week (for me it's every two weeks) you get a paycheck or direct deposit. When you don't go to work (retired) you're not expecting a paycheck and feel that you need to hoard or not spend any money because you're not working and receiving regular paychecks. Many people correlate working with a paycheck. No work, No paycheck.

— @frankmmiii

• Safe withdrawal rate strategies (including the 4% rule and beyond)

• Dynamic spending strategies and guardrails

I feel like Erin has my laptop bugged because I've built a spreadsheet that addressed nearly everything in this video. I can visually show how any retirement could potentially look like exactly as Erin noted. The problem? The slightest bit of complication instantly turns people off. I've tried showing my work to older co-workers and they ain't interested....this explains why annuities are so popular. People are mostly math illiterate, they want the simple, easy to understand paycheck that comes in every month.

— @mikevw6767

• Retirement income planning and cash flow design

• Social Security and guaranteed income strategies

Another outstanding video.

— @todd3812

• Sequence of returns risk and its impact on retirement income

• Essential vs discretionary spending in retirement

I worked in our state retirement office where we computed what a retiree was going to get. I saw what happened to retiree"s who did NOT prepare for their later years. Then I did not Make their mistakes. We retired with 6 checks berween the 2 of us, P sure hate to take any RMD's

— @anngordey1404

• How to build a flexible retirement withdrawal strategy

We also explore a powerful real-world example comparing two retirees with the same $1.5 million portfolio and identical success rates—but completely different retirement outcomes based on how their income is structured.

Excellent observations...thanks

00:00 Intro: The Problem with "Probability of Success" (Why 90% Isn't Enough)

01:22 What “Probability of Success” Actually Means? Understanding the Simulations

Hi Erin, great scenario and analysis. I agree spending is a big factor. I retired last year at 59 with 2 pensions and planning to take SS at 62. All of my essentials are covered and as a retired vet health care is covered. My investment will cover my leisures. Life is good!!! 😎👍

02:54 The Hidden Flaw: Why the Pass/Fail Model Fails Retirees

04:08 The Evolution of Planning: From Static Rules to Dynamic Real-Life Spending

5 years ago At 56 my financial planner and I went over my monticarlo stress test based on a very conservative rate of withdrawal and conservative rate of market return rate and it was 92% and he asked me if I was really sure I wanted to retire because of the risk 😂. Needless to say I retired at 57.

The goal in all of life is to thrive, not just survive. Proper retirement planning is not simply about having money left over, but maximizing your experiences and quality of life. Having a flexible spending plan and high guaranteed income sources increase the value of retirement.

Retirement came with an unexpected storm - I lost $500k to a scam. Today, I'm grateful to say the money has been fully recovered. That loss made me question every investment decision for months. The hardest part wasn't the money; it was rebuilding the confidence to invest again. Scams have become so sophisticated that even experienced people get caught.

This is the exact fear I had right before I retired at 55. Enough today is not the same as enough in 25 years. What finally settled it for me was not a bigger number, it was an income source that grows instead of draining down. Thinking of my retirement number as a floor instead of a ceiling changed every decision after that. My net worth absolutely must go up every year…short-term rentals are the answer for me.

I have been retired for some years and I have seen friends without substantial savings do okay. This works well especially with couples both with SS. However, when one passes things can get real tight. Healthcare and long term care can also wreck the best of plans. Thinking of these things in advance can be helpful during a trying time.

My retirement income is 2/3rds SS and 1/3 small pension. I was deeply in debt at 54 when I started saving for retirement. I'm doing ok, but as much as I enjoy watching Erin and all the others, I sure wish some of these good shows would inform the bottom half of retirees - the ones who get under $2000/month SS. I watch these shows with their discussion of "buckets" and the $750k in savings, and it's like NOBODY cares about the bottom half where I live! People with $750k have ZERO to worry about. Who cares about them? They obviously figured it out - probably as a dual income couple while we were divorced single parents struggling to pay bills and feed the kids.

80-90% success is a common target? Russian roulette has a 83% success rate! That seems way too risky. If you build a bridge, we don't want a 90% success rate. Even aiming for barely 100% success in the expected worst case is too low. You need to add a margin of error to that. You design to withstand something like 160% of the worst case.

90% chance of success doesn't actually mean you ran out of money 90% of the time. It's on a bell curve, so anything 50% or higher is actually 100% successful. Distilling it down, it is simply the probability you may have to make an adjustment. Let's not forget that MC sim was permitted after heavy insurance industry lobbying to enable insurance companies to market annuities using gamified metric a la MC. It is misleading and the industry puts too much emphasis on the probability of a probability of unknowable outcomes couched as predictable future outcomes as a way to sell products or services.

Let's look at social security. I started taking my social security at 66, which was my full retirement age. I've been collecting for 8 years. I totaled up what has been paid to date, which is $410,400. If I live to 90, which is what most advisors tell you to plan for, without factoring in cost of living increases, I will have received $1,094,400. COL will probably push that to $1.2 million.

That is not an inconsequential amount. Most people don't realize how much in social security they will receive over the course of their retirement. Most folks will not run out of money. They will die with much more than they had when they retired.

— @HALWG51

endorsements.

Let's be clear - NO normal person living in the US will run out of money, SS won't be stopping; what may run out is someone's equity / investment portfolio

So True Erin. Thank you for yet another fantastic video.

@jimgleason4040

Now that I am 70, I really am not bothered about travelling around the world. I never thought I would be like that. I feel I have travelled enough. Too tiring! So my advice is travel in your 40s 50s and 60s. Travel everywhere that interests you. You may run out of energy and motivation later. You may be different to me, but I know of many people my age who just want to stay at home and live their best life.

@britinportugalcl7256
@

The biggest problem with the 90% stat is it's a point in time. This plan, evaluated at this time would have a 10% chance of failure (far better btw than almost anything else we do in life). As you noted, your plan is not static and rational adults will make adjustments as they age and circumstances demand. You're spot on with this.

@jimhatch5873

Erin, this is a wonderful roll-up and synthesis of contemporary retirement planning! Nicely done.

@bobmcdonald6245

This video is very helpful for my situation. Hopefully will pull the retirement switch and the dynamic spending model is exactly my plan. One unknown for me is how to read the market to know when to cut spending. I am currently thinking of taking a “check” quarterly….do I look back just one quarter for what the market did and if down take less the next quarter? Do I Iook back two quarters before adjusting? Do I go back up after one quarter of recovery etc…would be great to have a video that goes into that aspect of dynamic spending.

@SheSpeaksTruthRC

SSA is a constant that never runs out. Unless you are completely out of the loop. One will adjust spending to income. No one has the same income thru out their lives.

@kennethwers

90% success sounds great until you realize it means 1 in 10 scenarios you run out of money. RetireSure Simulator (Apple App Store) runs Monte Carlo projections on your specific numbers so you can see exactly what that probability means for your spending and timeline.

Hi Erin, Question: I have both a regular brokerage account and a Roth account. I'll be 62yo this year. Do you recommend to put all money into my Roth account since I'll be retiring in a few years and my $ will be in my Roth for 5 years by time I retire? Thanks

@breakingchainsoffoodaddict3098

Ive always wondered (and admittedly never tried to figure out) how my retirement income goal was around 60% meanwhile my success rate was around 80%. It all makes sense now. Thank you.

@dustinmclean7899

I have set up my partner and myself's retirement so that our SS and a small pension more than cover basic living costs my post tax brokerage account and her 401K can sit there and only be used for fun stuff. But of course when she hits 73 she will be in the forced RMD world where my money is all post so none of that. In a down market no need to touch my brokerage account. I think the key is no debt and a mix of both pre tax and post tax savings give a couple way more flexibility with income. My thinking is I want 100% chance of success not even 90 is enough for me.

My 401k site shows my contribution and historical earnings calculate I'll have 125% of my goal. While that sounds like an amazing thing, in my case it's because I've had type 1 diabetes since 1985, so I'm already at the point where I know I will not have a long retirement. If I knew I was going to have a 30-year retirement that would be an entirely different thing. A 5-10 year retirement is extremely more likely for me.

40 years ago when I was a lad, I already knew that in retirement, one should pull money out of the market when it is up and have a 2-3 years worth of money out of the market to help smooth things over for when the market drops. There really isn't anything new. Reap the highs and coast the lows.

@brianburnside5949

EXCELLENT information. In my opinion, you are absolutely correct. Having spent over 40 years in the finance industry, I did not have a formal “model” but did possess many of the fundamental philosophies you mentioned. I was concerned about running out of funds, but now eight years after retirement, I can feel quite confident that we will not encounter any issues. I am currently working on not “protecting” my portfolio, which is quite challenging. We are comfortable, but after years of being responsible stewards of funds, we need to adopt a broader “guardrail.” IRRMA is a significant factor for us at this point.

@herb7877
@

I use Boldin, and it runs Monte Carlo projections (whatever that means) and states I have 92% chance of "funding your plan through longevity." What are the Monte Carlo projections? Is it an industry standard or a marketing term? Thanks for a great show. People close to retirement appreciate all your hard work.

@BillCalkins
@

60s - go, dawg, go! Need the money in greater supply.
70s - slow go, but still going.........less money needed.
80s - going dependent on health status............even less money needed unless the government gets more involved in our lives. Plan for that!
90s - if ya make it, way less money needed for everything. Hope you all planned accordingly and you male to this level.

If someone gave me financial advice with only a 80-90% chance of success, I'd fire them immediately...

It's like if someone told me to invest in Bonds and leave compound interest on the table, I'd be forced to question their intelligence...

Thank the Gods I've realized that superfluously spending money doesn't buy happiness. In a few hours I could drive to a state or national park and have a better lived experience than someone who buys an expensive plane ticket for some expensive trip to a foreign land...

I don't need to work overtime to invest 20% of my income. Or, to live the life I want to live today... I've decided to grill out at least two times a week this summer and fall. Way tastier than eating out and cheaper too... 😉

Knowing what you need to be happy is a financial insight most people never realize...

@Meditations2024

“Sacrificing your current self for your future self” hits home because that has always felt like the responsible way to live. The whole idea of not spending what you COULD spend (lifestyle creep) is anathema especially to people who want to retire early, so flipping a switch to living more for your current self is hard. I just retired 2 weeks ago at 57 and I knew this would be a struggle (but I’ll take that struggle over working longer!).
