Social Security Timing – SWR Series Part 59

September 5, 2023 – Welcome back to a new blog post in the Safe Withdrawal Rate Series! It’s been a while! So long that some folks were wondering already if I’m all right. Nothing to worry about; we just had a busy travel schedule, spending most of our summer in Europe. First Italy, Switzerland, Austria, and Germany. Then, a cruise through the Baltic Sea from Sweden to Finland, Estonia, Latvia, Poland, Germany again, and Denmark. But I’m back in business now with a fascinating retirement topic dealing with Social Security timing: What are the pros and cons of deferring Social Security? If we set aside the ignorant drivel like “you get an 8% return by delaying benefits for a year” and look for more serious research, we can find a lot of exciting work studying this tradeoff. Earlier this year, in Part 56, I proposed my actuarial tool for measuring the pros and cons of different Social Security strategies, factoring in the NPV/time-value of money consideration and survival probabilities. A fellow blogger, Engineering Your FI, has done exciting work studying this tradeoff using net present value (NPV) calculations. And Open Social Security is a neat toolkit for optimizing joint benefits-claiming strategies.

But those calculations are all outside of a comprehensive Safe Withdrawal Rate analysis. How does Social Security timing interact with Sequence Risk? For example, can it be optimal to claim as early as possible to prevent withdrawing too much from your equity portfolio during a downturn early in retirement? In other words, if you’re interested in maximizing your failsafe withdrawal rate, you may feel tempted to pick a potentially suboptimal strategy from an NPV point of view. Sure, you underperform in an NPV sense on average if you claim early. But hedging against the worst-case scenarios may be worth that sacrifice.

Let’s take a look…

The 4% Rule Works Again! An Update on Dynamic Withdrawal Rates based on the Shiller CAPE – SWR Series Part 54

October 12, 2022 – As promised in the “Building a Better CAPE Ratio” post last week, here’s an update on how I like to use the CAPE ratio calculations in the context of my Safe Withdrawal Rate Research. I have studied CAPE-based withdrawal rates in the past (see Part 11, Part 18, Part 24, Part 25) and what I like about this approach is that we get guidance in setting the initial and then also subsequent withdrawal rates based on economic fundamentals. That’s a lot more scientific than the unconditional, naive 4% Rule. In today’s post, I want to specifically address a few recurring questions I’ve been getting about the CAPE and safe withdrawal rates:

  1. Can a retiree factor in supplemental cash flows like Social Security, pensions, etc. when calculating a dynamic CAPE-based withdrawal rate, just like you’d do in the SWR simulation tool Google Sheet (see Part 28 for more details)? Likewise, is it possible to raise the CAPE-based withdrawal rate if the retiree is happy with (partially) depleting the portfolio? You bet! I will show you how to implement those adjustments in the CAPE calculations. Most importantly, I updated my SWR Simulation Google Sheet to do all the messy calculations for you!
  2. With the recent market downturn, how much can we raise our CAPE-based dynamic withdrawal rate when we take into account the slightly better-looking equity valuations? Absolutely! It looks like, the 4% Rule might work again! Depending on your personal circumstances you might even be able to push the withdrawal rate to way above 4%, closer to 5%!
  3. What are the pros and cons of using a 100% equity portfolio and setting the withdrawal rate equal to the CAPE yield?

Let’s take a look…
