Perp fee and liquidation calculator
Leverage decides where you get liquidated, and fees plus funding decide how far the price has to move before you are level. This works out both from numbers you type in. Nothing is sent anywhere, and every change updates the link so you can share a scenario.

How to use the calculator
- Enter the collateral you plan to post, in USDG, and the leverage you intend to use.
- Enter the price you expect to open at, and the maintenance margin you want to assume.
- Enter the taker fee for your tier, the funding rate you expect per 8 hour period, and how many days you plan to hold.
- Read the liquidation price and the distance to it first, then the total cost and the breakeven price.
How the estimate works
Liquidation uses the standard isolated-margin formula: your position can lose roughly one divided by your leverage, minus the maintenance margin, before the collateral no longer covers the requirement. At 10x that is about a 9.5% move against you with a 0.5% maintenance margin, and at 50x it is under 2%.
Arcus does not publish a maintenance margin per market, so that field is an estimate you control rather than a number read from the exchange. Cross margin behaves differently again, because the rest of your balance stands behind the position. Treat the output as a planning figure, not the exact price the exchange will use.
Fees assume you take liquidity on the way in and the way out, at the tier rate you enter. The base tier is 0.045% standard, halved to 0.0225% during beta, and the beta schedule is temporary. Funding is applied three times a day at the rate you enter, positive meaning longs pay shorts.
What the numbers mean
Distance to liquidation is the honest headline. A number under about 5% means an ordinary session can close your position before your view has a chance to play out. Total cost is fees plus funding over the period you entered, and the breakeven price is where the trade stops losing money once those are paid.
This is a model, not a quote. Slippage, a moving funding rate, and partial fills all change the real outcome. Perpetual futures are leveraged and most people who trade them lose money. Nothing here is financial advice.
Questions about this calculator
Is this the exact liquidation price Arcus will use?
No. It is the standard isolated-margin estimate. Arcus does not publish a maintenance margin for each market, and cross margin uses the rest of your balance as backing, so the real trigger can differ. Use this to plan a position, then check the figure the app shows before you commit.
Which fee should I enter?
Your perps taker tier. Tier 0 is 0.045% standard and 0.0225% during beta, and tiers improve as 30-day volume grows. Maker orders are a different schedule, currently zero for the first five tiers in beta. Both beta schedules are temporary.
What does the funding rate do here?
Funding settles three times a day on a perp. A positive rate means longs pay shorts, so a long held for days bleeds a little each period even if the price never moves. The calculator multiplies your position size by the rate and the number of periods.
Why is my breakeven price above my entry?
Because you pay a taker fee on the way in and again on the way out, plus funding while the position is open. The price has to move far enough in your favour to cover all of that before the trade is level.
