# Fees

> How trading fees work on Arcus — the maker/taker fee-tier model and where to read live fee values

Trading fees on Arcus follow a **maker/taker fee-tier model**: the rate you pay depends on whether your order adds liquidity (maker) or removes it (taker), and on your tier, which is driven by trailing trading volume.

<Note>
  This page is conceptual. Your current tier and the live fee schedule are returned by [`GET /v1/feetiers`](/api-reference/public/get-fee-tier-table); always read fees from the API rather than hard-coding them. You can also check your latest fee tier from the [Arcus portfolio page](https://app.arcus.xyz/portfolio).
</Note>

## The model

* **Maker** orders rest on the book and provide liquidity; **taker** orders execute against resting liquidity and remove it. Makers are charged less than takers, and high-volume tiers can earn **maker rebates**.
* **Tiers** are determined by your trailing trading volume over a rolling window. As your volume grows, you move into lower-fee tiers automatically.
* Funding payments are **not** a fee — they are transfers between traders. See [Funding](/concepts/perpetuals/funding).

## Current state

* **Spot trading is free at launch.**
* **Perp fee tiers** publish closer to launch — set to be competitive with leading perp venues, with maker rebates for market makers and high-volume traders. Specific rates per tier are read from the API once live.

<Note>
  Because the exact schedule is still being finalized and will change over time, this page deliberately avoids quoting rates. [`GET /v1/feetiers`](/api-reference/public/get-fee-tier-table) is the source of truth, and your portfolio page shows your current tier.

## Account costs beyond trading fees

* **Deposits/withdrawals:** Arcus charges no fee of its own; USDG deposits and withdrawals carry zero fees. Third-party processing or conversion costs (for card/fiat or cross-chain routes) are shown upfront. See [Onboarding & deposits](/concepts/onboarding).
