# Trading Fees View spot rates, maker rebates, referral benefits, and the assets you can use to pay trading fees. Polyester charges a trading fee whenever a spot order fills. Your fee rate depends on your **VIP tier** and whether the fill is classified as **maker** or **taker**. For eligible buy orders, you can also choose which asset pays the fee. There is no fee to place or cancel an order that does not fill. ## Spot trading fee schedule | VIP tier | Maker fee | Taker fee | | -------- | --------- | --------- | | VIP 0 | 0.1% | 0.15% | | VIP 1 | 0.08% | 0.135% | | VIP 2 | 0.065% | 0.12% | | VIP 3 | 0.05% | 0.105% | | VIP 4 | 0.04% | 0.09% | | VIP 5 | 0.03% | 0.08% | | VIP 6 | 0.02% | 0.07% | | VIP 7 | 0.015% | 0.06% | | VIP 8 | 0.0125% | 0.055% | | VIP 9 | 0.01% | 0.05% | | VIP 10 | 0.005% | 0.045% | Fees are calculated from the value of each completed fill. If an order fills in several parts, the applicable fee is calculated separately for each fill. > **Your VIP tier determines your rate** > > This table shows each tier's base rate. Symbol-specific adjustments, rewards, and referral discounts can lower your effective rate. Authenticated API clients can call `GET /v1/spot/fee-rates` for exact rates by symbol. See [VIP Tiers](https://testnet.polyester.com/docs/user-docs/fees-and-vip/vip-tiers) to learn how your tier is determined and how to progress to the next level. ## Maker and taker fees | Role | When it applies | | ----- | --------------------------------------------------------------------------------- | | Maker | Your order rests on the order book before another order fills against it. | | Taker | Your order fills immediately against liquidity already resting on the order book. | A limit order can be both: any quantity that fills immediately pays the taker rate, while quantity that rests and fills later pays the maker rate. ## Maker rebates Polyester supports maker rebates: a negative maker fee credits your account when an eligible maker order fills. Exact maker rebate rates are coming soon and will be published here. ## Choose how your fee is paid Most exchanges decide the fee asset for you. On Polyester, an eligible buy order lets you choose **Quote** or **Received** from the **Fee Source** selector in the Order Form. Your choice appears again when you review the order. - **Quote** pays the fee with the quote asset you are spending. When buying BTC/USDT, the fee is paid in USDT. - **Received** deducts the fee from the base asset you receive. When buying BTC/USDT, the fee is paid in BTC. The percentage rate does not change. The fee is calculated in the selected asset: | Fee source | Calculation | Effect on a buy order | | ---------- | ---------------------------------------- | ------------------------------------------------------------------------ | | Quote | Fill value in the quote asset × fee rate | You spend slightly more quote asset and receive the full base quantity. | | Received | Base quantity received × fee rate | You spend the entered quote amount and receive slightly less base asset. | Let's say Bitcoin is currently trading at **$100,000** and you buy **$1,000 of BTC** at a **0.08%** fee rate. - With **Quote**, the fee is **0.80 USDT**. You spend 1,000.80 USDT and receive 0.01 BTC. - With **Received**, the fee is **0.000008 BTC**. You spend 1,000 USDT and receive 0.009992 BTC after the fee. Sell-order fees are deducted from the quote asset received from the sale. For example, selling 0.01 BTC for 1,000 USDT at a 0.08% rate returns 999.20 USDT after the 0.80 USDT fee. > **Fee Source is available on eligible buy orders** > > Quote is the default. The Received option appears only when the selected market and order support paying with the base asset you receive. ## Referral discounts and rewards Referral codes affect positive trading fees in two different ways: | Who receives the benefit | Benefit | What it applies to | | ------------------------ | -------------------------------------------- | ------------------------------------------------------ | | Referred trader | 4% lower trading fees | Positive maker or taker fees on eligible fills | | Referrer | 15% of the referred user's paid trading fees | The fee remaining after the referred trader's discount | The referral benefit is calculated from the trading fee, not the order's full value. Let's say a referred trader completes a **$1,000** fill at a **0.08%** fee rate: 1. The standard trading fee is **0.80 USDT**. 2. The 4% referral discount saves the trader **0.032 USDT**. 3. The referred trader pays **0.768 USDT**. 4. The referrer earns 15% of that paid fee, or **0.1152 USDT**. Referral discounts and rewards apply only when a positive trading fee is charged. They do not create a negative fee or maker rebate.

A maker order rests in the order book and adds liquidity, typically achieved through limit orders. A taker order executes against liquidity in the book, typically consumed by market orders.
