Maker fees generally apply when an order adds resting liquidity to an order book, while taker fees generally apply when an order executes against liquidity already available. Fee tiers change the applicable rates according to a venue’s published eligibility rules, so understanding trading costs requires checking both execution behavior and the account’s actual tier.
What makes an order a maker or a taker?
An order book contains bids to buy and offers to sell. A trader supplies liquidity by leaving an executable order available for another participant to trade against. A trader consumes liquidity by accepting an available price. The maker and taker labels describe the role of an execution, rather than whether the trader is buying, selling, opening a position, or closing one.
A market order ordinarily takes liquidity because its purpose is immediate execution. A limit order can do either. If its limit price crosses an available opposing quote, it can execute immediately and incur taker charges. If it rests on the book before another order matches it, the resulting execution can qualify for maker charges under the venue’s rules.
A single order can also have mixed results. One portion might immediately match available liquidity while the remainder rests. The trade history may therefore contain separate executions with different fee treatments. Reading only the order type or the average execution price can conceal that distinction.
Calculate the charge from the execution
For a simple percentage schedule, the basic calculation is trading fee = executed notional × applicable fee rate. The relevant notional definition depends on the instrument. Spot notional commonly reflects quantity multiplied by execution price, while derivatives require attention to contract size, settlement conventions, and whether the contract is linear or inverse.
Hypothetical example: an execution has a notional value of 2,000 currency units and an illustrative fee rate of 0.04%. Its charge is 2,000 × 0.0004 = 0.80 units. These numbers are invented solely to demonstrate arithmetic and are not an exchange’s quoted fees.
Calculate each execution separately when prices, rates, or settlement currencies differ. A displayed percentage might exclude other costs, and the fee may be deducted from the purchased asset, collateral, or a designated balance. Currency conversion can change the reporting value even when the contractual charge is unchanged.
Understand what a tier actually measures
A fee tier is a set of conditions associated with a particular schedule. A venue might use eligible trading volume over a rolling window, asset holdings, account classification, or multiple conditions. None of these criteria should be assumed. The published schedule should identify eligible markets, calculation boundaries, evaluation frequency, and the treatment of subaccounts.
Rolling volume is different from lifetime volume. Activity can leave the measurement window, potentially changing eligibility without a new trade. Some schedules update after a periodic assessment; others may apply changes through a different process. The account interface and execution records should establish which rate actually applied at the time.
Check whether the schedule is marginal or applies a new rate to subsequent eligible executions. Do not assume a higher tier retroactively reprices completed trades. Also distinguish volume discounts from temporary campaigns, negotiated arrangements, and optional payment discounts. Their conditions and interaction may differ.
Lower posted fees do not guarantee a cheaper trade
The economic cost of execution includes more than the posted charge. A useful framework is total execution cost = explicit fees + spread cost + market impact + other relevant carrying or transfer costs. This is an analytical decomposition, not a promise that every component can be measured precisely.
A resting order may receive a favorable fee treatment but remain unfilled. The market can move away while the order waits. Alternatively, it may fill when incoming information makes the resting price unfavorable. That adverse-selection risk is part of providing liquidity, even if the execution earns a rebate.
An immediate execution pays for certainty of execution timing, subject to available liquidity and order controls. Its spread and slippage costs can exceed a small difference between maker and taker rates. Comparing fees alone therefore misses the trade-off between execution price, fill probability, urgency, and inventory exposure.
Read rebates and post-only controls carefully
Some schedules express a maker rebate as a negative fee. A rebate reduces the explicit execution charge or creates a credit according to the venue’s terms. It does not guarantee a profitable trade, and its settlement currency, eligibility, or treatment during special conditions may matter.
A post-only instruction is designed to prevent an order from immediately taking liquidity. Depending on the venue, a crossing order may be rejected, canceled, or adjusted. The exact behavior must be checked in the order documentation. Post-only does not guarantee that an order will fill, remain at its original price, or avoid all execution risk.
Other instructions can change outcomes too. Immediate-or-cancel and fill-or-kill describe execution constraints, while reduce-only limits how a derivatives order affects exposure. These controls serve different purposes; none should be treated as a universal maker-fee setting.
Audit the cost of a complete trading cycle
A round trip includes entry and exit executions. Hypothetical example: entering and exiting an unchanged illustrative notional of 2,000 units at the hypothetical 0.04% rate creates 0.80 units of fees on each side, totaling 1.60 units before spread, slippage, or carrying costs. Real exit notional can differ because price or position size changes.
For perpetual futures, funding is separate from maker and taker trading charges. Borrowing costs, liquidation-related charges, withdrawals, and settlement fees may also sit outside the headline schedule. Each item belongs in a cost review only when it actually applies to the product and account.
A practical audit compares the published terms, the account’s displayed eligibility, and the execution ledger. Record notional, execution role, rate, charged amount, and currency for a small sample. Investigate discrepancies before extrapolating projected costs. Increasing trading activity purely to obtain a discount can create additional costs and exposure that outweigh the discount itself.
Key takeaways
- Maker and taker describe each execution’s liquidity role, not merely the order label.
- Verify tier eligibility, update timing, and the actual rate charged.
- Compare total execution costs, including spread and slippage, rather than fees alone.
- A rebate or lower tier rate does not establish profitability.
