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.

Roughly works out to
Fee per trade—
Round trip (buy + sell)—
Estimated fees per year—
—
Register with code BN5262 for up to 20% off fees. Formula at the 20% ceiling: 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.

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, models the maximum 20% fee-discount scenario for code BN5262. The actual rate depends on current Binance rules. This is a reduction in fees, not free money; with the same assumed rate, more trading produces a larger estimated 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.
