Leverage calculator
Put in a stake and a multiplier. You get exposure, what it costs to open, the move that just covers that cost, and the move that costs you the entire wager. Then it checks that second distance against how far this market genuinely travels in one session, which is usually the part that ends the conversation.
How the numbers are derived
Exposure is stake multiplied by leverage. Profit and loss is exposure multiplied by the proportional move, which is why the stake sets the size of the bet and the multiplier sets how little the market has to move to end it. Losses stop at the wager, so the downside leg of every figure here is clamped there.
The model prices a long from the ask and marks it on the bid, and a short the reverse, so a spread would be charged in the direction a real round trip pays it. Moon publishes no spread, so that adjustment is currently zero rather than guessed at. If Moon's settlement price carries one, and third-party testers say it does, every figure here is better than the real fill.
The position ends when losses reach the wager, and Moon holds no maintenance buffer ahead of that, so the adverse move that costs you everything is simply 1 ÷ leverage. The distance collapses fast: 10.000% at 10x, 1.000% at 100x, 0.100% at 1000x.
The cost line is the part most calculators get backwards. Moon charges its opening fee on the wager and explicitly not on leveraged exposure, so it does not scale with the multiplier. A $100 wager costs $1 to open at 10x and $1 at 1000x. Both the fee and the max loss distance scale with the wager, so their ratio has no leverage in it at all: the fee always costs 1% of the distance between entry and the price that ends you.
Which means cost is not the argument against a high multiplier. Runway is. Check the distance this tool returns against how far the market opposite actually travels in a session, because that comparison is the whole decision.
Every number this tool returns is a model, not a fill. Indicative example based on third-party market data. Moon's reference price, spread, fees, settlement and liquidation rules may produce a different result.
where these numbers came from
The opening fee this tool defaults to, and the rule that the loss stops at the wager, are both taken from Moon's own documentation rather than assumed. The fee page works the arithmetic through every rung on the ladder and shows why the cost column stays flat while the runway column collapses.
