What a 10,000 USDT futures trade actually costs on Bitbase

The image is from Bitbase's help-center guide: the web order panel on the BTCUSDT perpetual with the Limit and Market tabs, price and size fields, TP/SL and the Open Long / Open Short buttons.

The base rates (VIP0)

• Maker: 0.02% (your order rests in the book and someone else fills it)
• Taker: 0.06% (your order fills against resting orders, like a market order)

Bitbase's Sept 4, 2026 fee change raised several taker tiers and left every maker rate untouched. VIP0 stayed at 0.02% / 0.06%. Rates can also differ by region, and Bitbase's futures terms say they vary by pair, maker or taker status, account tier and promotional arrangements, so check the fee page inside your own account before you plan around them.

Worked example: 10,000 USDT notional

Fees are charged on both the opening fill and the closing fill.

• Taker in, taker out: 6 + 6 = 12 USDT
• Maker in, maker out: 2 + 2 = 4 USDT
• Maker in, taker out (common when a stop or market close gets you out): 2 + 6 = 8 USDT

Another way to read the same numbers: a taker round trip needs price to move 0.12% in your favor just to break even, while a maker round trip needs 0.04%. On a scalp that targets a few tenths of a percent, that difference is most of the edge.

Why leverage makes it feel bigger

Leverage doesn't change the fee. It is calculated on the position's value (quantity x price), not on the margin you put up. Bitbase's own margin guide uses the formula Initial Margin = Position Value / Leverage, so for the same 10,000 USDT position:

• At 5x you post about 2,000 USDT, and the 12 USDT taker round trip is 0.6% of it
• At 10x you post about 1,000 USDT, and it is 1.2%
• At 20x you post about 500 USDT, and it is 2.4%

Same trade, same fee in USDT, very different bite out of your collateral.

The VIP ladder (maker / taker after the Sept 4 change)

• VIP0: 0.0200% / 0.0600%
• VIP1: 0.0180% / 0.0550%
• VIP2: 0.0160% / 0.0500%
• VIP3: 0.0140% / 0.0450%
• VIP4: 0.0120% / 0.0400%
• VIP5: 0.0100% / 0.0350%
• VIP6: 0.0080% / 0.0300%
• VIP7: 0.0050% / 0.0250%

At the top tier, the same 10,000 USDT trade costs 5 USDT taker/taker and 1 USDT maker/maker. Trades executed before the 14:35 UTC change on Sept 4 settled at the old rates; fee changes don't apply backward to completed trades.

Three cost lines, not one

Bitbase's formula is Realized PNL = Closing PNL + Funding Fees - Trading Fees. So:

• Trading fees: the maker/taker math above
• Funding: paid or received while you hold through a settlement, based on the position's notional at that moment, and it can go either way. The interval and timing are set per contract, so read them on the contract page. A close order that hasn't filled yet does not take you out of a settlement.
• Slippage: market orders don't promise the displayed price

Since July 16, 2026, Bitbase shows opening and closing fees as separate lines in position details on the web. One quirk: positions opened before that date show a closing fee of 0, because the closing fee was merged into the opening line. That is a display limit, not a free close.

Practical habits

• Use limit orders where you can. Post Only is one of the listed order types, and it makes sure an order only ever pays the maker rate, never the taker rate.
• Decide in advance how you'll exit. A stop that fires as a market order pays taker even if you entered as maker.
• Check your VIP level and fee page before a busy week, not after.
• Size by the margin you can afford to lose, then subtract the round-trip fee from your target.

Futures carry real risk of losing more than you planned, so treat fees as part of the risk budget, not an afterthought.
