Round-Trip Fee Break-Even Calculator
Buy, then sell, and you pay a fee twice. So "as long as the price doesn't drop, I'm fine" is an illusion — the price has to climb past two fees before you actually break even. Put in your buy price and fee rate and it works out the break-even sell price and how far the price has to rise. This is arithmetic, not a profit forecast, but it shows you whether all those small round-trips are worth it.
How it works: a round-trip pays a fee on the buy and again on the sell. The break-even sell price S satisfies S ×(1 − f − slippage) = buy price ×(1 + f + slippage), so S = buy price ×(1 + f + slippage) ÷ (1 − f − slippage); the required rise % =(S ÷ buy price − 1)×100; the total round-trip cost is roughly that same required-rise %. Your fee rate is whatever Binance shows on your account — BNB fee discount, maker vs. taker, and VIP tier all change it. Tip: don't chase a tiny target profit with frequent round-trips; the two fees eat the move before the spread even opens up.

How the tool works
When you buy, you pay the buy price plus a fee; when you sell, a fee comes out of what you receive (and if there's slippage, each side drifts a little too). To "break even" means the net you get after selling is exactly what you spent on the buy. Solve that equation and you get the break-even sell price: the buy price times (1 plus fee plus slippage), divided by (1 minus fee minus slippage). How much higher that break-even price sits above your buy price is how far the price has to rise before you stop losing — and that number is also close to the total cost of one round-trip.
Try the defaults to get a feel for it: buy price 2000, a 0.1% one-side fee, no slippage, and the break-even sell price is about 2004 — roughly a 0.2% rise just to get square. That looks tiny, but if you round-trip a dozen times a day hoping for a fraction of a percent each time, the fees stack up fast.
How to use the number to decide
Compare the "required rise %" against your target profit on the trade: if you're after 0.3% and break-even alone needs a 0.2% rise, only 0.1% is actually left to pocket — a touch of slippage and you've worked for nothing. The higher that line sits, the less you should be doing high-frequency small round-trips — which is exactly why fees are the headline issue in grid trading and short-term scalping. To push that line down, get clear on your fee rate first: see how fees are calculated. To also total the full buy-and-sell cost and net proceeds in one go, use the fee calculator.
