What if you'd bought SBUX every Starbucks run?
If you'd bought $1 of SBUX every time you walked into a Starbucks since May 2016 — roughly ten runs a month — you'd have put in about $1,210 and be holding around $1,706 worth of Starbucks today.[1]Based on historical returns. Past performance doesn't predict future results. That's about 6.7% a year. Above your contributions. Below the market.
The short version
- $10 a month into SBUX for ~10 years became about $1,706 from $1,210 contributed. Money-weighted return: ~6.7% annualized, as of April 2026.
- SBUX is the ubiquitous-cash-machine story, not the growth-darling story. The returns reflect that.
- The journey included a 33% peak-to-trough drawdown in 2022, when the reopening bump faded and the China business wobbled.
- What this article describes hypothetically, Slyce does automatically: purchases at Starbucks trigger a fractional-share buy of SBUX, receipt by receipt.
The number, set up honestly
The math: ten $1 contributions a month, starting May 2016, each buying SBUX at that month's adjusted close (dividends reinvested — SBUX has paid one since 2010 and it matters over this window). Run 121 months. End in April 2026.
Contributed: $1,210. Current value: about $1,706.[1]Based on historical returns. Past performance doesn't predict future results. That's roughly $496 of gain on a decade of $10-a-month purchases — a 1.4x on money spread across the whole window, not dropped in at the start.
The internal rate of return on that cash-flow stream is about 6.7% per year.Based on historical returns. Past performance doesn't predict future results. For scale: the S&P 500 has historically returned roughly 10% per year nominal since 1957.[2]Based on historical returns. Past performance doesn't predict future results. SBUX underperformed the index over this specific window. It still finished above the pile of cash a reader would have had by sitting on $10 a month for ten years — but by less than a broad index fund would have done.
Why we're showing you the loser by half
Worth saying: SBUX is here because we wanted one of these spokes to look ordinary. In 2016 you didn't know SBUX was going to compound at 6.7%. You didn't know if it would match the index, beat it, or trail it. It trailed it.
That's the spoke's whole point. A spend-to-own account doesn't sort for winners. It sorts for where you spend. If your latte habit is real, the holding is real, and the return is whatever Starbucks as a public company actually did — not what you hoped it would do. See the spend-to-own guide for the full thesis and the counterfactual spokes that cover companies that compounded faster and slower than this one.
What Slyce actually does
You don't open the Slyce calculator to simulate this. You order the same oat milk latte you order every morning, and Slyce buys a fractional share of SBUX for you on the way through.
The mechanic: you connect the card or account you pay with. Purchases at Starbucks pass through a rule that routes a small percentage — the default is 3% — into a real brokerage account in your name. The shares are SBUX, not a derivative or a token. They pay the SBUX dividend, vote with SBUX, and sell on any normal brokerage execution. Your Slyces tracks the holding; The Feed tracks the receipts.
The point of doing this automatically is the same point as the McDonald's version of this math or the Chipotle version of this math: the capture happens at the moment of purchase, not in a separate ritual that most people never get around to.
The shape of the return
The ending balance is the story the article opens with. The drawdown is the part that would have made you quit.
SBUX's worst peak-to-trough decline over the window was a 33% drop in 2022, when the reopening trade unwound and the China reopening failed to arrive on the schedule everyone priced in.[1]Based on historical returns. Past performance doesn't predict future results. On the DCA trajectory, that meant watching a position worth around $1,350 earlier in the year fall into the high $900s by the autumn. At that point you'd contributed roughly $760 — so the position was still above water on paper, but not by much, and the line going down felt permanent.
It recovered. Not dramatically, not to a new high the next quarter, but grindingly — dividends kept landing, the 2023 earnings stabilized, the number drifted back up. By 2026 the DCA account was up about 40% on contributions. The story is the grind, not the spike.
This is the part of a 10-year return chart that doesn't photograph well. A chart smooths the grind into a line that only goes up. The lived experience is years where nothing happens and months where the line falls.
Pitfalls
Three specific things to name, not just as disclaimers but as real risks to the idea of buying SBUX because the calculator said it worked.
Survivorship bias. SBUX is one of the 20 tickers in the Slyce calculator's pre-built set. That set is drawn from companies that are still publicly traded and still relevant to retail spending. Coffee chains that were large retail spenders and are now defunct or private — Caribou Coffee, Gloria Jean's — would have been on an equivalent list in different years. They're not here now. The calculator's universe is survivor-biased by construction, even when the survivor is a middling performer.
Concentration risk. The math above is one ticker. A spend-to-own account that only ever buys Starbucks ends up concentrated in Starbucks. The intended shape of a Slyce portfolio is the mixture of tickers your spending actually touches — SBUX plus groceries, gas, restaurants, rideshare, travel. One-ticker concentration is the tail risk; diversification comes from the breadth of the wallet, not from an asset-allocation model.
Past returns ≠ future returns. SBUX compounding at 6.7% over the 2016–2026 window does not mean SBUX compounds at 6.7% over the 2026–2036 window. Mature consumer-staples stocks have periods where the math is a grind and periods where a dividend-plus-modest-growth story reprices. The S&P 500's long-run ~10% tells you what diversified equity has done across many of both.[2]Based on historical returns. Past performance doesn't predict future results.

FAQ
How was the $1,706 number calculated? We pulled SBUX's monthly adjusted closes from Yahoo Finance for the window May 2016 – April 2026, simulated $10-per-month dollar-cost averaging (ten $1 purchases, matching a roughly every-other-weekday Starbucks run), and computed the ending portfolio value using the April 2026 close with dividends reinvested. Contributions total $1,210; the portfolio finished around $1,706. Re-runs will differ as the window rolls and prices move.
What was the worst moment in that decade? Autumn 2022. SBUX drew down about 33% from its 2021 peak. A DCA account started in 2016 would have been holding roughly $980 of SBUX at that trough — on about $760 contributed at that point. The account was above water on paper but trailing the plain act of leaving the money in cash. Recovery was gradual through 2023 and 2024.
Does this include dividends? Yes. Starbucks has paid a quarterly dividend since 2010 and has raised it most years. The adjusted-close series we used reinvests those dividends at the month's close. For a stock like SBUX with a ~2% yield, the reinvested dividend is a meaningful share of the total return, not a rounding error.
Can I actually buy fractional SBUX through a normal broker? Yes. Every major U.S. broker supports fractional SBUX orders — you place the order in dollars and the broker computes the share fraction at execution. The mechanical capability is why spend-to-own works at all. The slyce you'd own through this product is the same fractional SBUX you could open at Fidelity; the difference is the trigger mechanism.
Why $1 per transaction and 10 transactions per month? Those are the defaults in the Slyce calculator for Starbucks, drawn from typical coffee-run patterns. If your actual Starbucks spend is different, run the calculator with your own numbers — it recomputes the trajectory for any contribution rate.
What if SBUX underperforms again? If you're still contributing, you buy more shares at lower prices — the DCA mechanic dampens the pain. If you've stopped, you collect the dividend and wait. The long-horizon math for a name like SBUX is less about the spike and more about the dividend compounding; a flat decade with a 2% yield still ends above where it started.
Next steps
If you want to run this same math against your actual spending — the chains you actually shop at, the amounts you actually spend — the Slyce calculator does it for 20 tickers at once. The ending balances matter less than the shape: how much you'd have contributed, where the drawdowns were, and how much of the total came from the dividend versus the price.
