US stock token trading cost calculator
On a single buy, how much do the fee + spread actually eat? Work it out before you order. You can also compare the difference once an estimated referral discount is applied (whether it applies is explained in the note below).
Note (rates checked 2026-09): real stocks carry a 0.05% platform fee with a minimum of USD 0.17 per order (Binance's promotional rates, valid until 2026-09-30; the standard rates are USD 0.35 per order under USD 340 and a 0.10% spread above it) — this calculator only works on the percentage and does not include that floor, so on small tickets your real fee may be higher than what you see here; bStocks trading takes no commission, but there is a spread on both sides of any trade. Spot token rates also vary by account tier and whether you pay fees in BNB, so a generic reference value is used here. Whether the referral discount and the BNB offset count towards the stock platform fee is per Binance's fee page at the time, and the actual rate and spread are whatever Binance shows live on its page. This tool is pure front-end, collects no data, and its results are for reference only, not investment advice.
