Stablecoin to shares calculator

Say you have 1,000 USDT and the order screen shows 150 for the stock you want. You get six whole shares and two thirds of another, before fees. That division is all this tool does, in either direction, with the rounding shown. Binance Academy's guide says a stock order under [Trade] > [Stock] can be paid with supported crypto such as USDC, USD1, USDT, U or BNB. The calculator covers the three stablecoins in that list. The dropdown only changes the unit label, so type the price in the same unit you are paying with.

How the rounding works

Binance's guide says bStocks go to 8 decimal places and stock positions to 9. So the quantity shown here is rounded down to 8 decimal places, which is the most a bStock balance can hold. When the guide describes converting a stock position into bStocks, anything past the eighth decimal can't be tokenized and stays with the issuer as a rounding difference; the guide says that "does not represent a fee or charge". On a normal order size it is a tiny amount, but it is why the last digits of a converted balance can look short.

A worked example (made-up price)

1,000 USDT at a price of 150 is 1,000 ÷ 150 = 6.66666666 shares after rounding down, shown as 6 whole shares plus 0.66666666 of one. The 150 is invented for the example. The other way round, 5 shares at 150 need 750.00 USDT before any fee.

What this leaves out

• Fees. Work out any trading fee your order screen shows with the trading fee estimator, and keep that much aside.
• Price movement and the spread. The fill can differ from the price you typed, and a market order can fill across several prices.
• The minimum order. The Academy guide and the launch announcement both put the starting point at as little as $5; the calculator flags amounts below that. The minimum for a given bStock on the spot market is on Binance's own trading pages.
• The stablecoin's own price. USDT, USDC and USD1 are separate tokens, and the tool doesn't convert one into another or into dollars.
