What this calculator includes
Eterna’s published futures rates are 0.014% maker and 0.035% taker. Hyperliquid’s regular perpetuals base rates are 0.015% maker and 0.045% taker, with lower rates at higher 14-day volume tiers and optional staking discounts.
What changes the real bill
The model excludes funding, spread, slippage, liquidation costs, network and withdrawal charges, special maker rebates, referral discounts, aligned quote asset reductions, spot-weighted volume, HIP-3 market pricing and reward valuations. Those can change your comparison substantially. The annual figure simply multiplies the monthly difference by 12; it does not predict future activity or fee schedules.
What about EHX staking income?
EHX revenue sharing is separate from the execution fee. This calculator does not subtract a hypothetical payout or assume a 50% personal refund. Understand the EHX model →
Volume is not capital
A $1,000 margin balance does not mean $1,000 of monthly trading volume. Volume counts the notional of each execution, including closing trades. Do not increase leverage or trading frequency to reach a cheaper tier.
Use your account as the final reference
The estimated tier assumes the same daily activity throughout a 30-day month. Compare it with your actual trailing 14-day volume and the fee rate shown in your account. Thresholds follow the strict “greater than” notation of the published Hyperliquid table.
