Binance US stock trading cost calculator
Enter a buy amount and a trade type to get Binance's charge, the market bid-ask spread, and what the two add up to as a share of the order.
Note: for real stocks, Binance's charge is prefilled with the promotional rates currently on Binance's stock fee page (checked in October 2026; the promotion runs until 2026-12-31 23:59 UTC). Binance charges no commission; orders with a trade value of USD 340 and below pay a platform fee of USD 0.17, and orders above USD 340 pay a 0.05% spread. The standard rates after the promotion are USD 0.35 and 0.10%, and the official help page, written at standard rates, puts the threshold at USD 350; this calculator's threshold and platform fee are fixed at the promotional values (340 / 0.17) and do not apply once the promotion ends. With "Real stock" selected, this calculator already applies that split in the "Binance charge" line, so the rate you enter only kicks in on orders above USD 340. The "market bid-ask spread (est.)" is the gap between buy and sell prices in the market: you estimate it yourself, it is counted separately from Binance's charge, and it is not an extra fee Binance collects. bStocks trading takes no commission, but the market spread is still there. Spot token rates also vary by account tier and whether you pay fees in BNB, so a generic reference value is used here; this tool does not factor in any referral discount or BNB offset. The actual charge and market spread are whatever Binance shows live on its page. This tool runs in your browser and uploads no data; its results are for reference only, not investment advice.
