KCEX fee math: futures 0% maker / 0.01% taker, round trip = notional x (entry + exit)
Key takeaway
KCEX's standard USDT-M futures rates are maker 0% and taker 0.01%. Spot is 0% / 0%. Those are the published standard rates, not a VIP ladder you apply for. Some pairs can show different numbers during promos, so the trading page for the pair still wins when it disagrees with the overview.
Fee math here uses only those published percents. No sample notional is invented. Round-trip cost is still notional times entry rate plus notional times exit rate.
Rates
- Spot maker / taker: 0% / 0%
- Futures maker / taker: 0% / 0.01%
- Some pairs may vary with promos; read the pair's fee display
Formula from the fee article
Trading fee = executed_quantity x execution_price x trading_fee_rate
That is notional x rate on each fill.
Round trip at the standard futures rates
Same notional both sides:
- Maker / maker: notional x (0% + 0%) = 0
- Taker / taker: notional x (0.01% + 0.01%) = notional x 0.02%
- Mixed: notional x 0.01%
A resting maker open and maker close pays no trading fee under the standard schedule. A market-in, market-out path pays 0.02% of notional total.
Break-even
Taker / taker needs a 0.02% favorable move to cover trading fees when notionals match. Maker / maker needs 0% on the fee line. Spread and slippage are still real; they are just not the fee schedule.
Funding
Funding fee = position_quantity x mark_price x funding_rate
KCEX does not take a cut of funding; it passes between longs and shorts. Positive rate: longs pay shorts. Flat at the snapshot: no funding that interval.
Leverage note
Do not quote a single max leverage number for KCEX in this post. Published sources disagree (fee-calculator FAQ text versus contract detail responses). Check the trading page for the pair you use.
Pairs
Standard futures rates apply as the default for USDT-M work, including $BTC.USDT, $ETH.USDT, $SOL.USDT, $XRP.USDT and $DOGE.USDT, unless the pair panel shows a promo override.
Mistakes
- Calling 0% maker a limited promo when the page presents it as the standard rate today.
- Ignoring a pair-specific promo rate that differs from 0% / 0.01%.
- Forgetting taker still pays 0.01% per side.
- Mixing funding into the trading-fee total without labeling it.
- Stating a single platform max leverage while sources conflict.
FAQ
Is the 0% futures maker automatic? Yes under the standard rate description: available on registration with no tier application.
Do deposits have a trading-platform fee? The fee-calculator page states 0 trading-platform fee on deposits and withdrawals, with minimum withdrawal amounts still applying.
Quick sanity check? Maker side: 0. Taker side: notional x 0.0001. Round-trip taker / taker: notional x 0.0002.
What should the screenshot show? The futures fee explanation table with maker 0% and taker 0.01% visible, or the fee-calculator summary of the same rates.
Decimal form
Futures taker 0.01% is 0.0001 per side. Same-notional taker / taker is notional x 0.0002. Maker sides at the standard rate are 0. Spot sides at the standard rate are 0.
Worksheet
- Confirm the pair still shows the standard 0% / 0.01% futures rates (or note the promo override).
- Decide maker or taker for the open.
- fee_open = notional_open x rate.
- Decide maker or taker for the close.
- fee_close = notional_close x rate.
- Add funding only for intervals you will hold.
If both sides rest as maker under the standard schedule, the trading-fee total is 0. Spread and slippage can still move your fill away from mid; those are market costs, not the fee schedule.
Promo overrides
The fee article states that some pairs may have different fees. A new listing can show a temporary rate on the trading page. When that happens, replace 0% / 0.01% in the worksheet with the pair's displayed rates. When the promo ends, revert to the standard row.
Leverage and risk parameters
This post does not state a single max leverage for KCEX. Fee-calculator FAQ text and contract-detail responses have disagreed in published materials. Use the trading page risk parameters for the pair you trade. Fee math does not need a platform-wide max.
Funding detail
Funding fee = position_quantity x mark_price x funding_rate. KCEX does not take a cut; the transfer is between longs and shorts. Positive rate: longs pay shorts. Negative rate: shorts pay longs. Being flat at the snapshot means you are neither side for that interval.
Pair habit
Default to the standard futures rates for $BTC.USDT, $ETH.USDT, $SOL.USDT, $XRP.USDT and $DOGE.USDT, then glance at the pair fee display before size. That two-step habit catches promo overrides without inventing numbers.
Deposit and withdrawal aside
The fee-calculator page describes a 0 trading-platform fee on deposits and withdrawals, with minimum withdrawal amounts still applying. That line is not a futures trading fee. Keep it out of the round-trip futures worksheet so the trading-fee math stays clean.
