Leverage sets how close the call sits
A margin call is the market tapping you for more collateral before it takes the trade. High leverage pushes that tap right up against your entry. See the final line on the liquidation calculator.
The price where the exchange calls
A margin call is the warning before liquidation — the point where your equity falls below the required maintenance level and the exchange demands more collateral or starts reducing your position. On crypto exchanges the "call" is usually just an email and a countdown; the auto-liquidation follows without waiting for your answer.
The price level: for a long, margin call price ≈ entry × (1 − (initial margin − maintenance margin)). At 5x with 0.5% maintenance, that's roughly 19.5% below entry. Cross margin muddies this — your whole account balance backs the position, so the call price depends on everything else you're holding, and one bleeding position drags the rest toward the line with it.
Respond to a margin call by reducing, not topping up. Adding collateral to a losing leveraged position is doubling down with extra steps — you're paying to keep being wrong. The calculator's job is making sure you knew the call price before entry, when walking away was still free.
