How to Automate Your Investing: Recurring Buys on Every Major Brokerage

Three of the four brokerages here support a genuinely automatic $1 recurring buy directly into a stock or ETF; Schwab’s regular-account automation is built around mutual funds instead, and Robinhood is the only one offering a daily schedule. Sources: each broker’s own help-center pages, 2026 — confirm current features before you set anything up.

The Autopilot Plan is built on one idea: a fixed amount, invested on a fixed schedule, with no decision required once it’s set up. That article covers the what and the why. This one covers the how — the actual settings screen, broker by broker, that turns “I should really automate my investing” into a recurring order that runs whether or not you remember it exists next Tuesday.

The mechanics are genuinely simple once you’ve done them once. But they are not identical across brokerages, and one of the differences below is the kind of thing that trips people up: a large, well-known broker that most people assume automates everything actually doesn’t — not for individual stocks and ETFs, anyway. More on that shortly. Nothing in this article ranks or recommends a specific brokerage; it explains what each one’s automation feature actually does, mechanically, as of 2026, so you can set it up correctly on whichever one you use.

What “Automatic Recurring Investing” Actually Means

At its simplest, a recurring investment is a standing instruction you give a broker once: on this schedule, for this dollar amount, buy this stock or fund — automatically, without you placing a new order each time.

The feature that makes this clean is dollar-based (rather than share-based) ordering combined with fractional shares. Instead of specifying “buy 2 shares,” you specify “invest $25,” and the broker converts that dollar amount into however many whole-or-fractional shares it buys at the market price that day. That’s what lets a $10-a-day or $50-a-week plan run on autopilot regardless of what a single share happens to cost — the mechanics of why that matters are covered in more depth in What Are Fractional Shares?; this article assumes that piece as background and focuses on the recurring-schedule feature itself.

Two things happen behind the scenes on the date you’ve scheduled: money moves (from a linked bank account or from cash already sitting in your brokerage account), and an order gets placed and filled, typically sometime during that day’s regular market hours. If the scheduled date lands on a weekend or market holiday, brokers generally roll the purchase to the next trading day rather than skipping it.

The Universal Setup, in Five Steps

Regardless of which broker you use, setting up a recurring investment follows roughly the same sequence:

1. Open the detail page for the specific stock or ETF you want to buy (not a general “deposit” or “transfer” screen — the recurring order is usually tied to a specific security).
2. Select the recurring or automatic investment order type, as opposed to a one-time buy.
3. Enter a dollar amount rather than a share count, so the fractional-share math is handled for you.
4. Choose a frequency and start date — the options that are actually available vary by broker, covered below.
5. Choose a funding source — a linked bank account (via ACH transfer) or cash already sitting in the brokerage account’s core/settlement position, again depending on the broker.

That’s the whole shape of it. The differences that matter are which securities each broker will let you put on autopilot this way, what the minimum dollar amount is, and how fast a schedule you can set — which is where the four major brokerages below genuinely diverge.

Fidelity

Fidelity supports recurring investments directly into individual stocks, ETFs, mutual funds, and its own “Basket Portfolios” product, across brokerage, retirement, HSA, and 529 account types [source: Fidelity, “What are recurring investments and how do you set them up?,” fidelity.com, 2026].

• Minimum: as little as $1 per recurring purchase for stocks, ETFs, and baskets ($10 minimum for mutual funds) [source: Fidelity, 2026].
• Frequency: weekly, every two weeks, or monthly [source: Fidelity, 2026].
• Funding: from your Fidelity core cash position or a linked bank account [source: Fidelity, 2026].
• Setup path: open the stock or ETF’s detail page, choose “Recurring Investment” from the Trade menu, select the security type (Stocks/ETFs, Mutual Funds, or Basket Portfolios), and enter amount, frequency, and funding source [source: Fidelity, 2026].

Vanguard

Vanguard added true dollar-based, fractional-share recurring purchases for its own ETFs directly in its brokerage account — a meaningfully newer feature than its long-standing mutual-fund automatic investment plans [source: Vanguard, “How recurring investing could help you save more,” investor.vanguard.com, 2026].

• Minimum: $1 for a recurring ETF purchase; amounts can run up to $25,000 per instruction [source: Vanguard, 2026].
• Frequency: weekly, biweekly, or twice-monthly options, set to repeat indefinitely or through a fixed end date [source: Vanguard, 2026].
• Funding: for ETF recurring purchases specifically, the money must already be sitting in the account’s settlement fund by the scheduled date — unlike some competitors, Vanguard’s ETF auto-buy does not itself pull directly from an external bank account on the purchase date, so you need a separate transfer or standing deposit set up to keep the settlement fund stocked [source: Vanguard, 2026; Bogleheads community documentation of the feature, 2026 — confirm current funding mechanics directly with Vanguard before relying on this]. Mutual fund automatic investments, by contrast, can draw from an external linked bank account [source: Vanguard, 2026].
• Dividend reinvestment: Vanguard ETF holders can separately opt to have dividends automatically buy more fractional shares of the same fund [source: Vanguard, 2026].

Robinhood

Robinhood’s recurring-investment feature is broad in scope: one interface handles stocks, ETFs, and crypto, and it offers the fastest schedule of the four brokerages covered here [source: Robinhood, “About recurring investments and orders,” robinhood.com, 2026].

• Minimum: dollar-based orders with no fixed floor beyond what a fraction of a share will accept; Robinhood’s own materials describe $10 as the most common recurring amount, though smaller amounts are supported [source: Robinhood, 2026].
• Frequency: daily, weekly, biweekly, or monthly — the only one of the four with a daily option [source: Robinhood, 2026].
• Funding: a linked bank account as the primary payment method, with an optional backup payment method so a recurring order isn’t skipped if the primary funding source runs short [source: Robinhood, 2026].
• A genuinely useful gotcha: not every security qualifies. Robinhood generally requires a share price above $1 and a market capitalization of at least $25 million, and it excludes inverse, leveraged, and volatility exchange-traded products, along with pre-IPO instruments and anything that doesn’t support fractional trading [source: Robinhood, 2026]. If you can’t find the recurring-investment option on a specific ticker, this eligibility list is the first thing to check.
• Dividend reinvestment (DRIP): available as a separate, distinct setting from recurring investments — worth turning on alongside your recurring buy if you want dividends working continuously too [source: Robinhood, “Dividend reinvestment (DRIP),” robinhood.com, 2026].

Schwab — the Exception Worth Knowing

Here’s the detail most people assume isn’t true until they check for themselves: Charles Schwab, one of the largest brokerages in the country, does not currently offer a fully automatic, schedule-it-and-forget-it recurring purchase into individual stocks or ETFs in a standard brokerage account.

Schwab’s fractional-share feature — “Stock Slices,” now folded into its general “fractional shares” branding — lets you buy a slice of most U.S.-listed stocks and ETFs for as little as $1, commission-free [source: Charles Schwab, “Fractional Shares—Invest in Stock Slices,” schwab.com, 2026]. That part works exactly like fractional investing at any other broker. The part that doesn’t carry over is automation: each fractional-share purchase at Schwab is placed manually. There is no recurring-schedule setting attached to Stock Slices the way there is for Fidelity’s, Vanguard’s, or Robinhood’s stock/ETF recurring investments. Schwab’s true “set it and walk away” automatic investing plan exists, but it’s built around eligible mutual funds, not individual stocks or ETFs [source: brokerage feature comparisons and Schwab’s own automatic-investing program documentation, 2026 — this is a narrower, more specific claim than most broker comparisons make, so confirm directly on Schwab’s site before assuming either way, since broker features change without much notice].

This isn’t a criticism of Schwab — its mutual fund lineup and overall cost structure remain competitive, and a Schwab account can still absolutely support the Autopilot Plan’s base rule if you’re comfortable investing in a low-cost index mutual fund instead of an ETF, or you’re willing to manually place the same-sized Stock Slices purchase yourself on a set day each week or month. But if the entire point of automating is to remove the recurring manual decision, a Schwab account currently asks you to make that decision by hand for individual securities — worth knowing before you assume otherwise.

Other Brokers Worth Knowing About

The four above aren’t the only options. SoFi Invest supports recurring investments with fractional shares starting around a $5 minimum, on a schedule you choose [source: SoFi, “How can I set up a Recurring Investment?,” support.sofi.com, 2026]. M1 Finance is built almost entirely around automation from the start — its “pie” structure lets you set target allocations across stocks and ETFs and automates ongoing contributions into that mix, with a $1 minimum [source: M1 Finance product pages, 2026]. Neither changes the underlying lesson here: check the specific mechanics — minimum, frequency, funding source, and which securities qualify — before assuming a broker automates the exact way you expect.

Beyond the Recurring Buy: Dividend Reinvestment

A recurring investment schedules new money coming in. A separate, older mechanism handles money the investment itself generates: a dividend reinvestment plan (DRIP). The SEC’s Investor.gov describes it plainly — a DRIP lets the cash dividends you receive get automatically reinvested into more shares instead of being paid out to you in cash, and many brokerage accounts and mutual funds offer this as a standing election you turn on once [source: SEC Investor.gov, “Dividend Reinvestment Plans (DRIPs),” Glossary]. It’s worth checking that this setting is turned on for whatever you’re accumulating, since it’s the second half of a fully automated position — new contributions on a schedule, and the dividends that position throws off automatically buying more of the same thing, rather than sitting as idle cash in the account.

What to Double-Check Before You Walk Away

A few practical details are easy to miss on the setup screen and worth confirming before you consider the job done:

• Which funding source you selected — a bank-linked ACH pull versus cash already in the account behave differently, and (per Vanguard’s ETF program above) aren’t always interchangeable on the same broker.
• What happens on a scheduled date the market is closed — most brokers simply move the purchase to the next trading day, but confirm this rather than assume it.
• Whether the specific security you want is actually eligible — as the Robinhood section above shows, not every ticker qualifies for a recurring schedule, and eligibility criteria differ by broker.
• How to pause versus cancel — every broker reviewed here allows you to pause a recurring investment (useful if cash is tight for a month) as distinct from ending it entirely; know where that toggle lives before you need it.

None of this is complicated, but a recurring investment that silently fails to execute because a funding source lapsed defeats the entire point of automating in the first place. A five-minute check every few months — not a daily obsession, just an occasional glance to confirm the last few scheduled buys actually went through — is a reasonable middle ground between “never think about it again” and “watch it constantly.”

There’s a specific moment worth being honest about: the first time a recurring investment gets skipped — a card expired, a bank link broke, a security briefly lost fractional-trading eligibility — and you don’t notice for a month or two. It’s rarely a disaster (you’ve simply under-invested for a stretch, not lost anything), but it’s exactly the kind of quiet failure that automation is supposed to prevent, which is why an occasional glance at the transaction history is worth the two minutes it takes.

The Bottom Line

Automating your investing is mechanically simple on every major brokerage, but the details genuinely differ: Fidelity, Vanguard, and Robinhood all support a true $1 automatic recurring buy directly into stocks and ETFs, with Robinhood uniquely offering a daily schedule and Vanguard requiring its ETF version to be pre-funded from the settlement account rather than pulled straight from a bank. Schwab is the outlier — its genuine automation, for now, is built around mutual funds rather than individual securities, even though its Stock Slices feature makes manual fractional purchases just as easy as anywhere else. Whichever broker you use, the setup itself takes a few minutes; the value comes from the months and years it then runs without you having to think about it.

Once it’s running, the two questions that matter most are what you’re buying and how you’re weighting the fear and greed rules — both covered in The Autopilot Plan.
