# Fees

There are only trading fees. There are no fees to claim a payout if a contract wins.

### Taker Fees

The fee we charge to takers follows a similar structure to other prediction markets.

We use the following formula \
\
$$fees = round Up (C \* feeConstant \* P \* (1 - P))$$

where \
\
*C = the number of contracts being traded*\
*P = the price of contracts in $*\
*feeConsant = the fee multiplier for the market*

roundUp = rounds up to the nearest centicent

Currently, the *feeConstan*t for all markets is 0.07.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.gammaswap.com/markets-and-trading/fees.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
