# Fees

### Fees

Probable charges trading fees to keep markets liquid, fair, and reliable — especially when prices are uncertain. Fees are not just a cost; they help balance the market, reduce noise, and reward traders who act with conviction.

***

#### Key Notes

* **Only takers pay fees. Makers trade free.** Providing liquidity on Probable is completely fee-free.
* Taker fees range from **0.01% up to 1.75%**, depending on market price
* Fees are highest when market trades at 50% probability
* Fees decrease as the price moves toward 0% probability and 100% probability

### How to check my fees?

* Your estimated fee is shown directly in the order preview before you confirm a trade.
* Fees update in real time based on price and order type.

### Price Curve

* Trades at extreme probabilities (near 0% or 100%): Lower fees due to reduced uncertainty
* Trades at equilibrium (50% probability): Higher fees reflecting maximum uncertainty and peak activity
