What does this perp trading cost calculator include?

It estimates round-trip trading fees, spread, slippage, funding over your holding period, and any other cost you enter. It does not provide a live quote or include unentered liquidation, borrow, withdrawal, or tax costs.

Does a 0% trading fee mean a perp trade is free?

No. Funding, spread, slippage, liquidation, and withdrawal costs can still make a 0% fee venue expensive. Use the calculator as a scenario estimate, then verify the venue's live terms and quote before trading.

Is the liquidation estimate exact?

No. The exposure warning is a rough leverage-based estimate before maintenance margin, mark-price rules, fees, and venue-specific liquidation mechanics. Use the platform's own margin calculator for an actual order.

Before you trade

What will this perp trade actually cost?

A 0% trading fee does not make a perp trade free. Estimate the round-trip cost from position size, leverage, fees, spread, slippage, funding, holding time, and other entered costs. The result is a planning scenario, not a live quote or liquidation guarantee.

Collateral ($) Your margin, not the full position. Leverage (×) Used to estimate notional exposure. Execution fee (%) Use maker or taker fee for the order you expect to execute. Round-trip spread (%) Your estimated entry and exit spread combined. Funding per 8h (%) Positive means you pay; negative means you receive. Holding period (hours) Funding periods are calculated as hours ÷ 8. Round-trip slippage (%) Your estimated execution impact on entry and exit combined.

Other costs: $0.00

Leverage warning

At 5× leverage, a 20.00% adverse move would consume the initial collateral before maintenance margin and liquidation rules.

How to read the estimate

The number is a decision filter, not a promise. A zero-fee venue can still be expensive if its spread is wide, funding is unfavorable, slippage is high, or the position is liquidated before the trade thesis works.

Component	What it estimates	What it leaves out
Fees	Entry and exit maker fee on notional exposure	Rebates, tiered schedules, withdrawal fees
Spread	Your entered round-trip quote difference	Market impact and price movement while filling
Slippage	Your entered execution impact on notional	Actual fill distribution and market movement
Funding	Funding rate multiplied by 8-hour periods	Rate changes between funding timestamps
Other costs	Optional withdrawal, bridge, borrow, or settlement estimate	Costs you did not enter
Leverage warning	Simple collateral ÷ notional exposure	Maintenance margin, mark price, liquidation fee, insurance fund

What to check before using a perp DEX

Confirm the venue's live fee schedule, funding convention, mark-price oracle, liquidation threshold, withdrawal rules, and market-specific spread. The calculator uses your entered assumptions; it does not fetch live venue data. Then compare the expected cost with the size and holding period of the trade—not just the headline maker fee.
