COMPLETE TRADE-COST MODEL

GMX fee calculator

Model the full cost of opening, holding and closing a GMX position. Live market funding and borrowing feed the estimate; you control fee, price-impact and execution assumptions.

Not just referral savings

The calculator keeps position fees separate from time-based and execution costs, so the discount is never overstated.

MODEL LIMIT: rates, price impact and execution costs can change before or during the trade. Positive price impact is not modeled. Confirm the final quote in the official GMX transaction panel.

Position fees

Most crypto markets use 4 bps when a trade improves long/short balance and 6 bps when it worsens it. Opening and closing are separate fee events.

Time-based costs

Funding can be a cost or a credit. Borrowing is separate and may apply only to the larger open-interest side. Both rates can change while a trade is open.

Verify before trading

Read the GMX fee guide and confirm the final values in the official GMX order panel. This tool does not predict future rates or execution.
