Fee calculator: what one trade actually costs

DongBiBa EditorsFront-end tool~2 min
Up front: this calculator just estimates fees — you enter the numbers, and the result is for reference only. This site mentions Binance and contains a referral link. If you register through it we may earn a referral fee, at no extra cost to you. We're an independent education site, not Binance's official page, and this tool is not investment advice.

A lot of beginners only notice it after their first trade: wait, where did that little bit go? That little bit is the fee. One fee looks tiny, but buying and selling back and forth, year after year, it can quietly eat a chunk of your money. This tool helps you do the math: type in a few numbers and instantly see what one trade, a round trip, and a whole year cost — plus how much you'd save by registering with a referral code. Like a friend sitting next to you, punching the calculator so you can see it at a glance.

Register with code BN5262 for a 20% fee discount. Formula: yearly fees × 20%.

🔒This calculator runs entirely in your browser and collects and uploads nothing. Results are for reference; the actual rate is whatever the platform shows at the time. This tool is not investment advice.

Once the math is clear, the part you save is just money you keep. Use a referral code when you register as a beginner to get a 20% fee discount — it costs nothing and adds nothing to your cost; you simply pay a bit less toll.

What each number means

Fee per trade: what one buy (or sell) costs you, equal to "amount × rate". Tick BNB and it's ×0.75 on top. Round trip: buying in and selling out is two trades, so it's double a single fee — which is exactly why frequent trading is expensive. Per year: your monthly count times 12 months, a rough yearly cost so you get a feel for what "churning back and forth" actually adds up to.

The last line, how much you save, estimates the 20% fee discount you get by registering with code BN5262. Note: this is a discount relative to the fees themselves — not free money out of thin air, but 20% less on the toll you'd have paid anyway. The more you trade and the longer you hold, the more obvious the saving.

Three things to remember as a beginner
Don't judge the rate by one number — read the real fee the platform shows at the time; don't trade back and forth often, since fees are charged per trade; use a discount if you can, the gap adds up over time. But none of that beats the single most important rule: only invest what you can afford to lose entirely.

Want to fully understand fees? Read these two: one is dedicated to exactly how the referral code saves you money and how much; the other walks you through the whole first-buy flow, from registration to placing the order. Do the math first, then act — you'll feel steadier.
