In plain English
What Maker fee means
A limit order can be a maker order if it is placed at a price where it does not execute immediately. It becomes available for someone else to trade against, adding displayed liquidity. Whether the fee is maker or taker is determined by how the order executes, not merely by the order label; an aggressively priced limit order can execute immediately as a taker.
Why it matters
The maker fee affects the net execution cost of limit-order strategies and can be important for frequent trading. Lower maker pricing is intended to reward orders that contribute to the order book, but waiting for a fill introduces execution risk: the market can move away, the order may be filled only partly, or it may fill during a fast adverse move.
Example
An exchange’s simplified maker fee is 0.10%. A trader posts a buy limit order that rests and later fills for $5,000. The maker fee is $5.00 ($5,000 × 0.001). If only $2,000 fills, the maker fee applies to that executed portion, subject to the platform’s fee schedule and rounding rules.
Quick answers
Common questions
Can a maker fee be negative?+
Yes. Some venues offer a maker rebate, meaning an eligible maker execution receives a credit rather than paying a positive fee. Rebates are not universal and may depend on the market, account tier, product, order type, or jurisdiction.
Does a maker order guarantee a better price?+
No. A resting order can provide price control, but it may not fill, may fill only in part, or may fill as the market moves adversely. The displayed fee is only one part of execution quality.
