Built a Binance fee calculator — enter position size, returns exact fee in dollars with BNB discount option

Binance fees are simple but the actual dollar quantity per commerce is straightforward to underestimate, especially on futures where charges are charged on notional value not margin.

Futures maker is zero.02%, taker is zero.04%. With BNB discount it drops to 0.018% maker and zero.036% taker. On a $50okay futures place that's $10 vs $9 — small per trade however adds up over volume.

Constructed a calculator where you enter your position measurement, choose maker or taker, toggle the BNB discount, and it returns the exact greenback charge.
