Both exchanges charge the same 0.02% maker fee on USDT perpetuals at base tier. The whole
execution-fee comparison therefore collapses to one number: Binance's taker fee is
0.04%, OKX's is 0.05%. (Note that many comparison sites list Binance at 0.05% —
that figure is outdated; the API reports takerCommissionRate = 0.0004.)
| Maker share | Binance | OKX | Difference |
|---|---|---|---|
| 0% (all taker) | $400 | $500 | $100 |
| 30% maker | $340 | $410 | $70 |
| 70% maker | $260 | $290 | $30 |
| 100% maker | $200 | $200 | $0 |
The pattern is exact, not approximate: the gap is (1 − maker share) × $100 per $1M.
At base tier Binance is cheaper or equal at every possible order mix, and the difference
disappears entirely for pure makers. There is no crossover point — this comparison, unlike
Gate's rebate math, has no "it depends" on the
fee side. VIP ladders higher up have different thresholds and rates on each venue; this
article is strictly about the tier you start on.
Fees are paid once per trade; funding accrues for as long as you hold. We pulled the full realized funding history for BTC-USDT perps on both venues for the 30 days ending July 18, 2026 (90 settlements each, from the exchanges' own history APIs):
| BTC-USDT perp, Jun 18 – Jul 18 | Binance | OKX |
|---|---|---|
| Cumulative funding (30d) | +0.474% | +0.388% |
| Average rate, annualized | +5.8% | +4.7% |
| Paid by a $100k long over the month | ≈ $474 | ≈ $388 |
Over that window a BTC long paid roughly $86 more per $100k on Binance — while a short received correspondingly more there. That single month's funding difference is comparable to the taker-fee difference on $860k of volume. Which venue's funding runs richer varies by coin and by month; check the live per-coin comparison on the monitor rather than assuming either venue is systematically cheaper to hold on.
In our July 18 snapshot Binance listed 795 USDT perps against OKX's 412, and the two run different funding-interval mixes: 63% of Binance's cross-listed contracts settle more often than every 8h versus 48% on OKX (full census). More frequent settlement changes the annualized cost of an identical per-period rate, and 22% of cross-listed coins fund on different schedules on the two venues.
The venues are not interchangeable everywhere: OKX holds a MiCA license and serves the EEA; Binance's availability differs by jurisdiction. Neither is available in a number of markets at all — where you live can settle this comparison before any fee table does.
