Aster fees explained: maker, taker and total trading cost

The contract category comes first

Aster’s published perpetual fee page currently lists 0% maker and 0.04% taker fees for USDT perpetuals, 0% maker and 0.005% taker for USD1 general perpetuals, and 0% maker and 0.009% taker for RWA perpetuals. These are documented category rates reviewed on 5 September 2026, not a promise about every account, market, promotion or trading mode.

Check the live fee schedule and your account rate before using a preset. Spot, Shield and other modes are outside this table.

Calculate each fill, then add the costs

A fee is charged on traded notional, not just the margin you put up. For a linear position, quantity multiplied by execution price gives the notional for that fill. Multiply it by the applicable fee rate. Opening and closing are separate executions.

For an illustrative USDT taker round trip, a 10,000 entry notional costs 4 at 0.04%. If the exit notional is 10,500, the exit fee is 4.20. Total trading fees are 8.20 before any eligible rebate. The fee calculator lets you enter the two notionals independently.

A limit order is not automatically a maker fill

Maker and taker describe whether a fill adds or removes resting liquidity. An aggressively priced limit order can execute immediately against the book. A market order prioritizes execution and can fill at multiple prices. A lower nominal fee does not compensate automatically for missed fills or adverse price movement while waiting.

Compare executable outcomes: entry price, exit price, fee role and slippage. Our order guide explains the distinction without treating any order type as a guarantee.

Keep discounts, rebates and funding separate

Aster documents a 5% perpetual-fee discount for paying fees with ASTER. The referral program is a separate arrangement. Do not simply subtract two percentages from the fee rate or assume every benefit stacks. Confirm the account’s applicable rules.

AsterAtlas’s referral offer is 5% back on eligible perpetual fees, subject to Aster’s confirmation and terms. It is not 5% of traded volume. Funding transfers, liquidation fees and slippage are different cost categories. Use a zero rebate assumption unless you have confirmed eligibility.
