Reinvesting Dividends: How Compounding Works with STRC and SATA

The case for reinvesting comes down to a single pair of numbers I keep coming back to. Put $10,000 into SATA at 13% and spend every dividend, and twenty years later you are still collecting the same $108 a month you started with. Reinvest those same dividends instead, and by year twenty the position is throwing off around $1,438 a month — more than thirteen times the income, from the identical opening stake. Same instrument, same rate, same money in; the only thing that changes is what you do with the monthly payment. That gap is the whole case for compounding, and it is worth seeing exactly where it comes from.

Every month STRC and SATA pay you cash, and every month you make the same quiet decision: spend it, sit on it, or buy more shares with it. Take the cash and your share count never moves — next month's dividend is the same size as this month's, your income steady but flat. Reinvest it and your holding ticks up, so the following month you earn on a slightly bigger base, and the month after that on a bigger one still. Each payment buys a little more income-generating capital, and given enough years those small increments stop being small. That is all compounding is: earning a return on your returns, not just on the money you started with.

What it looks like on $10,000

Start with $10,000 of STRC at today's 11.50%. The first month pays $95.83. Spend every payment and your capital sits at $10,000 forever, handing you $1,150 a year — $23,000 of income over two decades, for an end position of $33,000. Reinvest every payment instead and the base compounds: about $11,213 after one year, $17,723 after five, $31,409 after ten, and roughly $98,600 after twenty. That is almost three times the cash-out result, from the same opening $10,000.

SATA tells the same story with more force, because the rate is higher. At 13% the first monthly dividend on $10,000 is $108.33. Cashed out, that is $1,300 a year and $26,000 over twenty years, ending at $36,000. Reinvested, the position reaches about $11,380 after a year, $19,089 after five, $36,437 after ten, and roughly $132,800 after twenty — more than three and a half times the cash-out total. The higher the yield, the harder compounding pulls.

The part that matters: income

Pot size is the headline, but the figure I find more telling is the monthly income at the end. The $10,000 STRC cash-out investor earns $95.83 a month on day one and $95.83 a month in twenty years' time — it never budges. The reinvestor's grown ~$98,600 position would, at the same 11.50%, pay roughly $945 a month — nearly ten times the income of someone who put in the same money and spent it along the way. For SATA the spread is wider still: $108 a month forever against about $1,438 a month on the reinvested ~$132,800. Same starting sum, an order of magnitude apart in income by the end.

That is why I treat reinvestment as a long-game decision rather than an income one. For the first few years the extra is barely noticeable — a few more dollars a month, easy to dismiss. It is the back half of the timeline that does the heavy lifting, and it only pays off if you leave it alone long enough to get there.

Why monthly payments help

Both instruments pay monthly rather than quarterly, and that cadence is quietly doing work. Every payment is a chance to put money back twelve times a year instead of four, and each reinvestment becomes part of the base the next one earns on. More frequent payments simply mean more compounding cycles, and more cycles mean a steeper curve over a long horizon. Monthly sits at a sensible spot for anyone who wants their dividends back at work without waiting a quarter for the privilege.

Run your own numbers

The figures above are just one example — yours will differ. The STRC and SATA Growth Projectors are built for exactly this: put in your own amount and time horizon and they lay the cash-out income stream and the reinvested growth side by side, out to twenty years, anchored to the current rate. It is far quicker than doing the arithmetic by hand, and it lets you test your real position rather than a round $10,000.

One honest caveat

Every number here assumes a flat rate for the whole run — 11.50% for STRC, 13% for SATA, held steady for twenty years. Reality will not be that tidy: STRC's rate resets, SATA's has moved since launch, the price you pay won't always be par, and tax takes a bite out of every dividend you reinvest. The projector makes the same simplifying assumption and says so plainly, so treat all of this as an illustration of the mechanism, not a forecast. What does hold, whatever the exact rate, is the shape of it — reinvestment compounds your income base, monthly payments compound it faster, and time is the ingredient that turns a modest yield into a serious one.

I track STRC and SATA daily and hold positions in their parent issuers (MSTR and ASST) rather than the preferreds themselves. If I were buying these for income, reinvesting is the approach I'd take — but that is my own view, not financial advice.
