Binance US Stocks vs Broker Cost Compare

How to use this cost comparator

The first field is how much you plan to invest, USDT or USD-equivalent counted as one number. The next three are the fees on the traditional broker path, which vary hugely by platform, so fill them from your own broker: the deposit wire fee is the fixed charge the bank takes when you wire renminbi or dollars from a bank into your brokerage account, commonly around twenty or thirty dollars per transfer (many brokers waive deposit fees — if so, enter 0); the FX spread is the slice the broker or correspondent bank quietly adds to the exchange rate when you deposit a non-dollar currency, usually a fraction of a percent; the per-side commission is the commission charged on each stock buy or sell, and plenty of brokers are commission-free now, so if waived, enter 0.

Once filled, the dark card on the right gives the result directly. The big number is how much the Binance path saves versus the broker — it equals "broker total cost" minus "Binance total cost." The two comparison bars below draw the two paths' total costs with whichever is higher filling the bar: the longer one is the pricier. The line beneath lists the two total costs as specific numbers. If you set all the broker rates to 0 (no wire fee, no spread, no commission), you'll see the two bars nearly level — and at that point cost is no longer the dividing line; what matters is something else, which the section below covers.

Where the two paths' cost structures really differ

On the Binance side, Binance itself doesn't charge commission for buying US stocks; the real charge is the platform fee of the custodian broker behind it, Alpaca: a flat 0.35 USDC for a single trade under $350, and 0.1% for $350 and above (go by Binance's page; verified 2026-06). You already hold USDT, so there's no wiring dollars in and no FX spread, and the barrier is as low as about $5 to get started. Count one round-trip (buy once, sell once) and the cost is two platform fees added together. On the traditional broker path, the money has to get in first — the wire fee and FX spread are tolls deducted before you've even bought, and the buy and sell each take a commission again. For small amounts, a wire fee of a few tens of dollars spread over a few hundred of principal is a striking share; the larger the amount, the more the fixed fees thin out and percentage fees dominate, and the gap between the two paths narrows. That's why this tool shows the biggest difference for people making "a small first attempt."

Note that everything computed here is cost — it excludes taxes, spread fluctuation, and the movement of the exchange rate itself. Broker rates differ by firm, and this tool only lays out the numbers you entered for a rough picture; it's no firm's quote.
