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, 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.
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.
