Part 1: Walkthrough of the SWR Toolbox
Do you want to avoid the biggest retirement risk? This simple to use tool will let you model your safe withdrawal rate and help ensure you don’t run out of money. In this walkthrough video, we teach you how to use this powerful, flexible, and FREE tool created by Karsten Jeske. Using the SWR Toolbox, you can ensure that you have a personalized plan that works with your own financial situation.
Part 2: Eric + Jason discuss how they’re using the SWR Toolbox and how Jason is struggling to spend as much as he can safely do in early retirement
How much money can you safely spend in retirement? In part two of this series on safe withdrawal rates, we discuss the #1 tool we’ve found to help you answer that question. Topics covered include the SWR Toolbox, our thoughts on Social Security, the challenges of spending in retirement, and how to get comfortable with increasing your withdrawal rate.
Download the Safe Withdrawal Rate (SWR) Toolbox
- The Safe Withdrawal Rate Toolbox is available via Karsten Jeske’s Early Retirement Now blog. The current version can be downloaded via Part 28 of the SWR series. This is also the post where the revisions to the calculator are described. To see the history of this tool, you’ll need to go back to Part 7. We found reading both posts to be essential to really understand how the tool works. Please ensure you follow the directions in the video to make your own copy of the tool. There’s no need to email Karsten to request edit rights!
Essential Blog Posts
Safe Withdrawal Rate series: This is the landing page for the 56-part SWR series (it will surely continue to grow) for which Karsten is best known. Be sure to start with the guidance he provides on how to navigate this great but expansive content. Many essential topics are covered in the series and not all of them involve deep dives into math! While we think all of his posts are interesting, you’ll find guidance below about the specific articles we think are most important to the topic of this video – in addition to Parts 28 and 7 listed above.
In the video, we mentioned the CAPE-Adjusted Safe Withdrawal Rate tab in the Toolbox, and talked a bit about what the Shiller CAPE is. While we didn’t go into details (yet – stay tuned), there’s ample material available on the blog for you to review if you’re interested in this topic. Big ERN recently wrote several posts concerning a new “better” CAPE ratio. This article introduces the concept, while the next, “The 4% Rule Works Again! An Update on Dynamic Withdrawal Rates based on the Shiller CAPE – SWR Series Part 54” dives into details on how his SWR Toolbox can use this factor to model withdrawal rate in retirement. If you’d like to try it out, these posts will definitely help you on your way.
Sequence Risk is more important than your average return rate. Surprised? Be sure to check out Part 15: More Thoughts on Sequence of Return Risk. As mentioned in the video, SWR is overwhelmingly determined by the first 10-15 years of portfolio drawdown.
Are you the kind of person who wants all the gory details about the math underlying the SWR Toolbox? If so, you won’t want to miss Part 8: Technical Appendix. It’s got all the information you need to fully understand how Karsten’s approach works. There are also some good references at the bottom of the post on related material found elsewhere.
Did you know we’ve spoken to Karsten twice before? “What the FIRE Community Gets Wrong” was the first time he came on Two Sides of FI. We covered a lot of ground in this episode about safe withdrawal strategies – so much so that we also released a follow-up video called “Karsten Spoke, We Listened. Here’s What We Learned”. These two episodes are popular with our audience for a good reason and are definitely worth viewing for anyone interested in SWR strategies.
Our second conversation with Karsten also featured Fritz Gilbert (from The Retirement Manifesto), in a continuation of their debate about the merits of bucket strategies. In “What’s Wrong with This Popular Retirement Strategy?” we covered a lot of ground that you won’t want to miss!
Other Show Notes
cFIREsim (or Crowdsourced Financial Independence and Retire Early Simulator) is a very popular and powerful FIRE calculator created by Lauren. We found a lot of value in this tool throughout our FIRE journey, and clearly many others do as well. In the developer’s words, “What can cFIREsim do? At its core, you can enter information in the a few simple inputs and return the basic simulation. At its most complicated, it can determine your portfolio success based on 80 individual portfolio adjustments, multiple types of inflation, multiple types of market returns, and graphically show you the results. There are many options to choose from outside of the ‘Basic Inputs’ ”
Variable Percentage Withdrawal (VPW) is another method besides CAPE-adjusted WR for allowing market conditions to influence the amount you take out of your portfolio in drawdown. As mentioned in part 2, VPW is popular among some adherents the Bogleheads approach to investing. As you’ll read at this link, this method “adapts adjustments to portfolio withdrawal amounts to the retiree’s retirement horizon, asset allocation, and portfolio returns during retirement… to allow the retiree to spend most of the portfolio using return-adjusted withdrawals. By adapting withdrawals to market returns, VPW will never prematurely deplete the portfolio.”
stickK is the app Eric mentioned to help track adherence to a goal – like keeping to spending your planned withdrawal rate. Created from a behavioral economics framework, stickK allows you to create “Commitment Contracts, [which are] a binding agreement you sign with yourself to ensure that you follow through with your intentions—and it does this by utilizing the psychological power of loss aversion and accountability to drive behavior change.” We’ve not tried this yet but this is a pretty appealing (an a little scary) idea!
You can find information on the tools we mention in each episode along with additional information in the Resources section of this site.

Great podcast. I completely understand Jason’s concern with withdrawing the maximum calculated withdrawal rate each year. Being conservative, I think is a normal trait, especially when doing something like retirement very early. I think the real reason for the conservatism is that – There is no guarantee of anything. While the calculator may be very proven, there is no Absolute Guarantee for you.
Thanks, Brad! So glad you liked it. I have moved up my withdrawal rate since the episode, but I’ve still got (for me) comfortable room between my WR and the calculated ceiling. Feels right to me for now, but we’ll see where it goes! -Jason
I’m glad to know that I’m not the only one that geeks out over the ERN SWR Toolkit. It really gives me a lot of confidence in the numbers that I’m looking at in retirement. I retire in 2 months, and am struggling with the concept of withdrawing my funds after being fed a paycheck for 30 years. I have some positive cash flows that will start in a few years from a former pension and have discounted Social Security. The ERN tool shows a really high withdraw rate – and I plan to take between 3.5-4% every year which is still well below the ERN rate. Great podcast and thanks for contributing to the community.
Thanks, Mark! Oh yes it seems you are not the only one 🙂 Congrats on getting into the home stretch! It is definitely a change. Just remember that this is also a paycheck, just one you are making to yourself. Best wishes to you!
