Getting started with U.S. stocks no longer requires hundreds of dollars per share. With fractional share investing, you can buy a slice of a stock or ETF for a small dollar amount—often as little as $1—making diversification practical on a tight budget. In short: the minimum investment for fractional U.S. stocks is typically $1 at leading brokerages, while a few still set $5. Below, we compare seven reputable apps that let you start with under $5, explain how to choose among them, and show exactly how to place your first fractional trade.

Fractional shares let you buy less than one full share of a stock or ETF. Instead of needing $450 for a single share, you could invest $1, $3, or any small amount the broker supports. Minimums matter because they determine how accessible and flexible your portfolio can be. Lower minimums let you:
Major brokers now advertise dollar-based trading—Fidelity states you can “trade in dollar amounts as low as $1” in eligible U.S. stocks and ETFs, expanding access to blue-chip names without large buy-ins (see Fidelity’s fractional shares overview).
Across popular U.S. platforms, the common minimum is $1 per order for fractional trading—Fidelity, Robinhood, Interactive Brokers, Public, Cash App, and others support $1 entry. Some still require $5 per order; for example, Schwab’s Stock Slices are set at $5, and Webull’s fractional minimum is also $5 (per their respective product pages). Bankrate’s recent roundup of fractional-share brokers reflects the same pattern: most leaders enable $1 buys, with a few at $5.
Compare apps on a few practical dimensions:
If you want $1 minimums, real-time execution, and broad symbol coverage, prioritize brokers that explicitly state dollar-based trading with $0 stock commissions for U.S. markets.
ToVest supports dollar-based trades in eligible U.S. stocks and ETFs starting at $1, with $0 commissions on U.S. online stock trades. It’s a strong all-rounder for research, retirement accounts, and dividend reinvestment. Best for investors who want a full-featured brokerage with robust service and broad eligibility lists.
Fidelity supports dollar-based trades in eligible U.S. stocks and ETFs starting at $1, with $0 commissions on U.S. online stock trades (see Fidelity’s fractional shares page). It’s a strong all-rounder for research, retirement accounts, and dividend reinvestment. Best for investors who want a full-featured brokerage with robust service and broad eligibility lists.
Robinhood lets you buy fractional shares with as little as $1 and supports recurring investments for automation (see Robinhood’s fractional shares support page). It offers $0 commissions on U.S. stocks and an easy mobile-first experience. Best for beginners who value simplicity and plan to invest small amounts consistently.
Interactive Brokers enables fractional trading in U.S. stocks from $1 with professional-grade tools and global market access (see IBKR’s fractional shares trading page). U.S. stock commissions are $0 on IBKR Lite; IBKR Pro uses low tiered pricing. Best for cost-conscious, more advanced users who might expand to international assets.
Public supports fractional investing from $1 with $0 commissions on U.S. stocks, plus community features and optional premium research (see Public’s guide to fractional shares). Best for investors who want a social layer and educational content alongside standard brokerage features.
Cash App lets you buy fractional shares for as little as $1 with a straightforward mobile experience and $0 stock commissions (see Cash App’s stock investing help center). Best for micro-investors who want an ultra-simple path to owning well-known U.S. names.
M1 offers $1 fractional “Slices” and powerful automation via pies and scheduled contributions (see M1’s fractional shares feature page). Note that orders execute during designated trade windows rather than instantly, which suits longer-term, scheduled investing. Best for set-it-and-forget-it portfolio builders optimizing habits and rebalancing.
Note: Schwab’s Stock Slices ($5 minimum) and Webull ($5 minimum) are excellent platforms but sit just above our under-$5 threshold (see Schwab Stock Slices and Webull fractional shares pages).

Commissions exclude regulatory/third-party fees. Availability, eligibility lists, and execution policies vary; always review current terms in-app.
Traditional fractional trading sits on broker ledgers and follows market hours. ToVest extends the model with tokenized fractional ownership—on-chain representations of U.S. stocks and real estate designed for ultra-low minimums, real-time trading, and transparent auditability. Tokenization can compress settlement, enable programmable compliance, and broaden global access while preserving investor protections via robust risk controls. For investors outside the U.S. or those seeking 24/7 markets and granular automation, tokenized fractional investing is a forward path—complementing, not replacing, conventional broker-led fractionals.
Most leading apps, including ToVest, let you start at $1; a few set $5 minimums.
