Bybit Referral Code BTC9149 | How Fees Work | 58% Off | Nov 2026

Bybit fees come down to one formula: executed notional value × applicable rate. What trips people up is the two variables hiding inside it. For futures, notional means position value, not the margin you put up. And the rate depends on whether you were a maker or a taker, plus your fee tier. This guide separates spot, perpetuals, and funding into three different calculations, gives a worked number for each, and then shows how referral code BTC9149 pushes your rate down.

1. Memorize One Formula First

Spot or futures, Bybit charges the same way:

Fee = executed notional value × applicable rate

On spot, notional is quantity times fill price. On futures, it is position size times fill price — nothing to do with how much margin you posted. That single difference explains most of the "why was I charged more than I calculated" complaints, and section 4 works through it with numbers.

The rate is set by two things: maker or taker, and your fee tier. A brand-new account sits at the base tier, where published rates are 0.10% for spot maker and taker, 0.02% maker and 0.055% taker on USDT perpetuals. Those numbers fall as VIP tier and 30-day volume rise; the fee page inside your account is always the real source.

One more detail people miss: fees are charged per fill. A large order matched in five slices produces five fee entries that add up. Unfilled and cancelled quantities cost nothing.

2. Maker vs Taker: Nearly 3x Apart

A maker order rests in the book and waits, adding liquidity for others to trade against. A taker order lifts an existing order, removing liquidity. Exchanges reward the first behaviour, so its rate is materially lower.

Product	Maker	Taker	Other cost
Spot	0.10%	0.10%	Conversion spread, withdrawal fee
USDT perpetual	0.02%	0.055%	Funding rate

On futures, maker and taker are 2.75x apart. Same view, same direction, same size — the difference is purely how you submitted. So futures traders should build one habit: if the entry is not urgent, rest a limit order; only take liquidity when timing matters.

Beware one trap: a limit order is not automatically a maker. If you price it through the opposite side and it fills on arrival, the system books it as a taker. The only guarantee is the post-only flag: it either rests as a maker or gets cancelled for trying to take.

3. Where Spot Fees Are Deducted

Spot works the opposite way to intuition: the fee is taken out of the asset you receive. Buy BTC with USDT and the fee comes off your BTC; sell BTC for USDT and it comes off your USDT. That is why the position you see after a buy is slightly smaller than the notional you traded.

Take BTC at 100,000 USDT, a 0.01 BTC buy, notional 1,000 USDT, rate 0.10%:

• Fee = 1,000 × 0.10% = 1 USDT, roughly 0.00001 BTC
• You receive 0.01 − 0.00001 = 0.00999 BTC
• Sell 0.01 BTC for 1,000 USDT and the fee is 1 USDT, leaving 999 USDT

With MNT fee payment switched on, the flow changes: BTC arrives in full and an equivalent charge is taken from your MNT balance at the applicable discount. Do not subtract the fee from the BTC a second time when you reconcile — check which asset the trade record lists as the fee currency.

This is also why leaving a little MNT in the account matters. Deduction only happens if the balance covers it; when MNT runs short the system falls back to charging the coin, and the discount quietly stops applying.

4. Futures Fees Use Position Value

The classic futures mistake is multiplying margin by the rate. Notional is position value, not margin. With 1,000 USDT of margin at 10x, the position is 10,000 USDT, and that 10,000 is the fee base.

On a 10,000 USDT position:

Order style	One side	Open + close
Taker both ways	10,000 × 0.055% = 5.5 USDT	11 USDT
Maker both ways	10,000 × 0.02% = 2 USDT	4 USDT
Maker in, taker out	2 + 5.5	7.5 USDT

In other words, a round trip costs 4 to 11 USDT, or 0.4% to 1.1% of the 1,000 USDT margin. A strategy targeting 0.5% per trade lives or dies on whether that rate was cut before the first order.

Two practical notes. The fee is debited from the available balance of the futures account at entry, so your effective margin shrinks slightly and the liquidation price shifts with it. And leverage does not change the rate — it changes notional, so the fee grows with it. Going from 10x to 50x leaves the percentage untouched while multiplying the fee five times on the same margin.

5. Funding Is Not a Trading Fee

Plenty of people fold funding into "fees" when budgeting, but the money goes somewhere completely different. Trading fees go to the platform; funding is paid between longs and shorts, and the platform keeps none of it.

The calculation is position value × funding rate, settled every eight hours on most contracts (a few differ). A positive rate means longs pay shorts; a negative rate reverses it. On a 10,000 USDT position at 0.01%, one settlement is 1 USDT.

Two consequences worth internalising: funding ignores leverage and looks only at position value, and it accumulates with holding time. Day traders usually never touch a settlement window; anyone holding for days should treat eight-hourly funding as part of the cost of carrying the position, not just the two trading fees at entry and exit.

6. Three Costs People Forget

Trading fees are only part of what leaves the account. Three more items usually show up:

• Withdrawal fees: fixed per coin and network, unrelated to size — which is why they hurt on small transfers.
• Conversion spread: instant swaps, fiat ramps, and card spending can carry a spread. It is not labelled a fee, but it is still a cost.
• Borrowing or margin interest: charged hourly and keeps accruing for as long as the position stays open.

P2P trades usually carry no fee for either side, yet the quote itself embeds a spread, so the cost sits in the price rather than a fee line. Judge any transaction by what actually lands in your account, not by the fee field alone.

7. Two Steps to Cut the Rate

Whether that 11 USDT taker round trip gets cheaper depends on two things being done:

Step one: enter referral code BTC9149 at signup. Binding it gives you a 33% trading fee discount that applies to every spot and futures fill. Sign up here: https://partner.bybit.com/b/BTC9149 — the field pre-fills through the link, or type BTC9149 manually if you register inside the app. This only works at registration; the window to add it later is limited.

Step two: switch on MNT fee deduction. It lives in the fee settings, and the account needs a small MNT balance that is not locked by open orders. The 33% discount and the MNT deduction stack to a maximum of 58% off trading fees. On the 11 USDT round trip above, that lands near 4.6 USDT.

Then verify it in three moves: check that the fee page already shows your discounted rate, place one small order, and compare the actual charge and fee currency in trade history. Only the number in trade history is real; a percentage on a campaign banner is not.

8. What Frequency Costs per Year

A few basis points look invisible on one trade and very concrete over a year. Assume 100,000 USDT of monthly notional, all taker, all USDT perpetuals:

Item	Base rate	At up to 58% off
Monthly fee	55 USDT	about 23.1 USDT
Annual total	660 USDT	about 277 USDT
Annual gap	about 383 USDT

That gap has nothing to do with whether the market went up or down; it is a certain expense. The more you trade and the larger the notional, the wider it gets. Someone doing one small spot buy a month may not notice — but binding the discount costs nothing either.

9. Four Common Misreadings

1. "Higher leverage means a higher rate." The rate depends on product and maker/taker only. Leverage enlarges notional, so the fee grows while the percentage stays put.
2. "A limit order is always cheaper." Price it through the book and it fills as a taker. Post-only is what actually locks the maker rate.
3. "Fees are the whole cost." Funding, withdrawal charges, conversion spreads and borrow interest all sit outside the fee line.
4. "The discount applies once I enter a code." You still need MNT deduction switched on, and you still need to confirm the real charge in trade history.

Summary: Know the Formula, Bind the Discount

Bybit fees are one sentence: notional value times the applicable rate. On spot the notional is coin value and the fee comes out of the coin; on futures the notional is position value rather than margin and comes out of the futures balance; funding is a transfer between longs and shorts and belongs to a different ledger. Get those three straight and the "why does the charge not match my math" question disappears.

To actually lower the rate: enter BTC9149 at signup (https://partner.bybit.com/b/BTC9149) for 33% off trading fees, then switch on MNT fee deduction so the two stack to a maximum of 58%, and confirm the real charge in trade history. It is a proportional discount, so the more you trade the more it saves — and it is the one cost item entirely within your control.
