Some help you decide something before you send money; the rest work out what it costs. All of them show their working, run in your browser, and send nothing anywhere.
Before you send anything
- 01 Which network should I send USDT on? Asks what the receiving side accepts before it asks about cost, because the cheapest network is the wrong answer if the other end will not credit it. Then the fee as a share, and the checks that apply to that kind of destination.
- 02 What format is this address, and which network family? Paste an address and see which family of networks its format belongs to. Bitcoin bech32 addresses are checksum-verified here; the rest get a prefix, length and character-set check, and the page says which you are getting. It will not separate Ethereum from BNB Smart Chain, because one address format covers both.
What it costs
- 03 Trading fee calculator Round-trip cost at a given tier, with and without the BNB discount, plus what that discount saves in actual money. Tier presets were read off the exchange’s own schedule on 2026-08-30.
- 04 Funding rate calculator What a funding rate costs to carry a position for a set number of hours, expressed against your margin rather than the notional. Change the leverage and watch the share move.
- 05 Liquidation price calculator Entry, leverage, side and maintenance margin rate in; the modelled price an isolated position gets closed out at, and the percentage move that gets you there. Solved rather than approximated, and still an estimate. Read the move, not the price.
What these actually are
Plain client-side logic and arithmetic. No API call, no price feed, no account, no storage, and nothing you type ever leaves the page — including any address you paste.
You can check that claim rather than take it: open your browser’s network tab and reload any of them. The only outbound requests are the stylesheet and the two font files, which is also what the privacy page says.
Where a calculator has built-in numbers — the fee tiers in the trading fee tool — those are typed-in constants read from the exchange’s published page on a stated date, not a live feed, and the page says so. Every tool takes the changeable figures as inputs rather than guessing them, because a calculator that silently assumes a stale rate is worse than no calculator.
What they deliberately do not do
Each one states its own simplifications on its page, and none of them should be used as a risk display for a position you already have open.
- The liquidation tool covers isolated margin only. Cross margin depends on your whole wallet balance and every other open position, which four inputs cannot describe.
- The funding projector assumes a constant rate and a constant position size. Real funding does neither.
- The address checker verifies a real checksum only for Bitcoin bech32 addresses. Everything else is a prefix, length and character-set check, which will not catch a typo that leaves the shape intact. The page says which you are getting.
- The network picker knows nothing about which networks your exchange actually offers, and it takes no view on whether a destination is trustworthy.
- None of them models your profit and loss, and none is a prediction of anything.
The figures on your trading screen are the ones that govern. These are for reasoning about a decision before you commit to it. The risk disclaimer is worth reading if you are here because you are about to use leverage.
Where the working is explained
Each calculator carries its own derivation underneath it, and the longer write-ups go further.
If you want the formula rather than the answer, the liquidation math derives both the long and short cases from first principles, the funding piece explains why the charge lands on notional, and the fee breakdown has the tier table with a dated screenshot of where it came from. The full list is in the write-ups.
