Maker-Taker Fee Model
The Formal Definition
An exchange fee pricing model that provides financial rebates to traders who add liquidity to the order book (makers) while charging fees to traders who remove liquidity (takers).
Net Venue Cost = Execution Commission ± (Maker Rebate / Taker Exchange Fee)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"On public lit exchanges, liquidity is money. If you place a limit order inside the book, the exchange pays your broker a rebate for creating liquidity. If you smash a market order, you are a liquidity taker, and the exchange charges a surcharge. In Tiered broker models, you keep that rebate; in Fixed models, your broker pockets it."

Examining the real numbers for: 10,000-share limit order resting on the exchange book
| Execution Metric | IBKR Pro (Tiered Pricing) | Retail Fixed Commission Broker |
|---|---|---|
| Fee / Rate | $35.00 base commission | $49.00 flat ticket fee |
| Spread / Buffer | Earned $0.0020/share maker rebate on ARCA | Exchange paid broker the $20 maker rebate |
| Execution / Status | -$20.00 rebate credited directly | Rebate retained by the brokerage firm |
| Total Cost / Result | Exchange rebates lowered total trade cost | Lost $34.00 to platform markup |
How Brokers Weaponize This Term
Brokers steer retail orders to market-maker wholesalers instead of lit maker-rebate exchanges because wholesalers pay higher PFOF kickbacks than public exchange maker incentives.

How do you qualify as a 'Maker' on a trade?
You qualify as a Maker by placing a non-marketable limit order that rests in the order book, providing liquidity for future participants.

An inverted exchange flips the standard structure by paying rebates to liquidity takers and charging fees to liquidity makers.
