# Fees

> Trading fees and fee structure on Decibel

Trading fees decrease automatically as your 30-day volume grows. Maker fees **drop to zero** at higher tiers, rewarding users who provide liquidity.

## Fee Schedule

| Tier | 30D Volume | Perps Taker | Perps Maker |
| ---- | ---------- | ----------- | ----------- |
| 0    | \< \$10M   | 0.0340%     | 0.0110%     |
| 1    | > \$10M    | 0.0300%     | 0.0090%     |
| 2    | > \$50M    | 0.0250%     | 0.0060%     |
| 3    | > \$200M   | 0.0220%     | 0.0030%     |
| 4    | > \$1B     | 0.0210%     | **0.0000%** |
| 5    | > \$4B     | 0.0190%     | **0.0000%** |

## Maker vs Taker

| Role  | Description                                               |
| ----- | --------------------------------------------------------- |
| Maker | Order adds liquidity to the book (rests before filling)   |
| Taker | Order removes liquidity from the book (fills immediately) |

A limit order that rests on the book before being filled is a maker order. A market order or limit order that fills immediately is a taker order.

### Fee Calculation

Fees are calculated as a percentage of the notional value of your trade:

```
Fee = Notional Value × Fee Rate
Notional Value = Position Size × Fill Price
```

## Builder Codes

Apps and trading tools can include a Builder Code in transactions to earn a portion of trading fees. If you're using a third-party interface or bot, a Builder Code fee may be included.

For details on Builder Codes, see the [Builder Codes guide](/quickstart/builder-codes).

## Funding Fees

Funding isn't technically a fee but a payment between traders. Longs pay shorts (or vice versa) based on the funding rate. For details, see [Funding Rates](/for-traders/funding-rates).

## Vault Fees

If you contribute to a vault, the vault manager may charge **interval-based performance fees** of 0–10%. Fees are crystallized at the end of each interval (30–365 days, set by the manager at vault creation). The manager only earns fees on intervals where the vault profited — if the vault loses money in an interval, no fees are charged for that period. See [Vaults](/for-traders/vaults) for details.

## Deposit and Withdrawal

Depositing and withdrawing USDC from your Trading Account requires gas (APT) for the transaction. There are no additional protocol fees on deposits or withdrawals.
