$200K vs $1.2M: A SATA + STRC Thought Experiment on Reaching F.I.R.E.

For years, the standard framework for retirement income has been the 4% rule.

The idea is simple: if you want $48,500 per year of spending, you would typically need roughly:

$48,500 × 25 = $1,212,500

In other words, about $1.2 million invested in a diversified portfolio to sustainably withdraw that income.

But recently I came across an interesting thought experiment involving two relatively new preferred securities.

Before diving into the math, it’s important to note that these securities ultimately sit within financial structures connected to Bitcoin, so they carry some exposure to the long-term success of Bitcoin itself. More on that later.


Two High-Yield Preferred Securities

Two securities caught my attention:

  • Strategy Series C Preferred (STRC) – currently yielding about 11.5%
  • Strive Asset Management Preferred (SATA) – currently yielding about 12.75%

Both are preferred securities issued by companies building financial products around Bitcoin treasury strategies.

An interesting feature is their dividend timing.

  • STRC has an ex-dividend date around the 15th of the month
  • SATA has an ex-dividend date around the 28th of the month

The actual cash payment arrives roughly 15 days later, but what matters for dividend eligibility is simply holding the shares on the ex-dividend date.

After that date passes, an investor can sell the shares and still receive the dividend.


The Rotation Idea

Because the ex-dividend dates occur at different times of the month, a strategy some investors discuss is rotating between the two securities:

  1. Hold STRC through its ex-dividend date (~15th)
  2. After the ex-date passes, sell and move into SATA
  3. Hold SATA through its ex-dividend date (~28th)
  4. Then rotate back to STRC and repeat

In theory, this rotation attempts to capture both dividend streams each month.


The Yield Math

Using approximate yields:

SATA: 12.75%
STRC: 11.5%

Combined:

12.75% + 11.5% = 24.25%

If an investor pays roughly 24% tax on the income:

24.25% × 0.76 ≈ 18.4% after tax

That’d give this investor $18,400 per a year income on $100k or $36,400 per a year on $200k.


The Early Retirement Thought Experiment

Suppose an early retired investor allocated $200,000 to this strategy.

At a 24.25% gross yield, the income would be:

$200,000 × 0.2425 = $48,500 per year

Under the traditional 4% rule, producing that same income would require:

$48,500 × 25 = $1,212,500

So the comparison looks like this:

StrategyCapital Required
Traditional 4% rule~$1.2 million
Preferred rotation idea~$200,000

That’s roughly a 6× difference in required capital.


Even More Interesting for Early Retirees

For some early retirees who structure their income carefully, qualified dividend income can fall within the 0% federal tax bracket.

In that scenario, the full 24.25% yield could theoretically flow through without federal income tax.

Using the same $200,000 example:

InvestmentYieldAnnual Income
$200,00024.25%$48,500

That level of income could cover a meaningful portion of living expenses for many households.


The Bitcoin Connection

It’s important to understand what ultimately sits underneath these securities.

Both STRC and SATA are part of financial structures built around companies holding significant amounts of Bitcoin on their balance sheets.

At the base of these preferred securities is therefore some degree of Bitcoin risk.

If Bitcoin were to fail as an asset class entirely, the underlying business models supporting these preferreds would likely fail as well.

However, if Bitcoin continues to grow and remain valuable over time, these structures should continue to function as designed.

It is also possible that as demand for these types of securities increases, the dividend yields could gradually decline. Markets tend to compress yields when large numbers of investors compete for the same income-producing assets.

So the yields discussed above should be viewed as the current state of the market, not necessarily a permanent condition.

Finally there is company risk. Strive (ASST) issues SATA and Strategy (MSTR) issues STRC. Either company could fail for some generic business reason and that woudl also be a risk, just like any business.


Final Thoughts

For decades, the 4% rule has been a useful guideline for thinking about retirement income.

But financial markets are constantly evolving, and new structures occasionally appear that change the math in interesting ways.

This rotation idea may or may not prove durable over the long run. But it highlights how emerging financial instruments—especially those tied to Bitcoin treasury strategies—are beginning to create entirely new types of income assets.

And sometimes, when you run the numbers, it’s worth pausing and asking:

Could the future of income investing look different than the past?

As of 3-16-2026 I started an account to do this specifically. I will share the results in a few months or at the end of the year to see how it’s gone and if anything has changed since I started this experiment.

All prices in the below table are per share. multiple the # shares x any price to get the total amount. I started with 10x $97.22 = $972.20 and a purchase of 10 shares of SATA.

You Probably Aren’t Saving Enough to Retire

This is an update and expansion of “You Might Need $3 Million to Retire at Age 65”.

See disclaimer at end. There are assumptions in these calculation that inflation is 3% constantly every year.

Your investments will return 7%/year.

These tables change if either of those numbers change. But these are useful historic numbers to help people start thinking if they are in the ballpark of saving enough or not. 

In the previous post I considered how much someone my current age at the time (28), might need to retire when they are 65. I have thought about this and it’s actually quite easy to make a table so that anyone whatever age and income level they think they might need could identify how much they need to save without doing any math!

How you read the below table is:

Identify from the top row “how much yearly income you need to retire (in 2023 dollars). So if you are spending say $50,000 this year and you think you’ll continue to spend that much in retirement go to that column.

Then identify your age and the age you want to retire. 

For this example say you are 40 and you want to retire at 60.

60-40 = 20 years to retirement. So you look in the left column and go to the row “20 years to retirement”

Where the column and row intersect is how much you might need to have at that age to retire. 

So in the example, if you are 40 years old, and you want to retire in 20 years and withdraw $60,000 a year (in 2023 dollars) from your portfolio you would probably need to have saved $2.7 million dollars in 2043 dollars)

The dollars in the resulting boxes are all in the calendar year of the year you’d retire. 

So in 2043 you’d need to have $2.7 million to retire. 

The table assumes you can safely withdraw 4% of your portfolio a year. 

4% of $2.7 million is $108,000, but that $108,000 is in 2043 dollars. 

Adjusted for inflation $108,000 is worth $60,000 in 2023 dollars, which is what the top column tells you. 

I tried to make this easy since everyone knows what their current spending is. That is why the top column is in present day dollars.

The next step would be to identify how much money you have now and determine if you’ll have enough at the time you retire to reach the goal in the table above!

The table below helps with that. 

How to read this table is to sum up your investments in all your accounts today.

Ex: 401k, IRA, Brokerage account etc. 

That is the top row.

Again, look at the column to identify “how many years until you want to retire”

The resulting orange box will tell you “how much you will have in that year if you don’t invest another dollar today.”

So in the below table our 40 year old person who wants to retire in 20 years and has $600k in their 401k & IRA & any other investments  will have $2.3 million in 2043, assuming they don’t invest another dollar between today and 20 years from now. 

Now this might at first seem unhelpful because you might be thinking “but they will likely be investing more between now and then”. 

And that is true!

But what this table tells you is that you NEED to invest more to reach you $2.7 million goal from table 1 if you want to retire with your expected withdrawal of $60k a year. 

Here’s a clean table for you to identify yourself on. 

Let’s look at a different scenario:

Say you are 40 years old and think you can live on $50,000/year in 20 years when you retire.

You’d look up that you’d need $2,257,639 in the year 2043 when you retire.

If you look at table 2 you can see that if you have $600,000 invested today, and plan to retire in 20 years you’d have $2,321,811 when you retire. 

Since you need $2.2 million but your investments will grow to $2.3 million this might mean that you don’t need to invest anything else for the next 20 years! 

This idea, that you might not need to invest any more money to retire in the future is known as “CoastFI”.

You can learn more about CoastFI here

Now as I mentioned right at the start there are 2 assumptions in all these tables.

  1. Inflation is 3% every year. It might be more or less in the real world.
  2. Your investments will grow at a steady 7%/year. This will certainly be more or less every year. It’s easy to do math with averages though and over time the ups and downs of the market average out. 

You have to make assumptions like this when doing these types of calculations. These are based on historic averages. Every person needs to do their own calculations or work with a financial advisor to get these numbers exactly right for themselves. 

But these are good starting points to just give you a high level view if you are even close to having enough money or if you’ll need to continue investing!

For most people you are likely going to not have enough invested now that you can stop investing. But how close are you?

Are you millions of dollars away? Or hundreds of thousands? Or only thousands?

I will create another post in the future to try to help understand how much you will need to invest to reach your goal, but I thought this was a sufficiently long post for now.
