Will My Balance Be Deducted After Liquidation?

Yes, but only the margin behind the liquidated position — not your whole account. Liquidation is the exchange closing a leveraged trade for you and settling the loss out of the margin you posted. Whatever the loss and the fees do not eat is returned to your balance. Money in a separate wallet, and spot coins you simply hold, are not touched.

What exactly comes out?

Three things, in this order: the loss on the position, the trading fee for closing it, and a liquidation fee that most exchanges charge on top — a small percentage that also feeds the insurance fund. On a position closed near its bankruptcy price, the three together usually consume the whole margin, which is why the figure you see afterwards is often zero rather than "a bit less".

Picture the margin as a deposit left at a hotel desk. At check-out the bill comes out of it and the remainder is handed back. If the bill is the size of the deposit, nothing comes back — but the hotel does not reach into your wallet for more.

Why isolated and cross end differently

In isolated margin, only the amount you assigned to that trade is exposed. An ether position liquidated with $50 of isolated margin costs you $50; the other $900 sitting in the futures wallet stays where it is. In cross margin, every free dollar in that wallet is backing the position, so the exchange keeps drawing on it until the position is safe or the wallet is empty. The same market move, a very different outcome.

What about funding fees?

On perpetual futures there is also a funding payment every few hours between long and short traders. It is small, but on a position held for days it quietly eats margin and moves the liquidation price closer. Plenty of people are liquidated by a move they thought they had room for, because funding had been shaving the buffer all week.

After a liquidation, download the trade history and read the liquidation and funding rows before deciding what went wrong — the real cost is rarely the price move alone. If a stop order was waiting at the time, read why liquidation happens even with a stop loss, or whether a balance can go negative at all.
