Searching for an OKX referral code? Here is what it actually changes.
OKX's own automatic invitee discount, its own published cap
60% total, paid partly by OKX's own discount and the rest by ReturnFee
Most OKX referral codes floating around only ever get you OKX's own standard invitee discount, the cap OKX itself sets in its affiliate program rules, no code can move it higher on its own. A code paired with a real rebate program adds further cashback on top, funded separately by that program, not by OKX. That is the only way the total goes higher, and it is worth checking before you trust a page that claims otherwise.
What ReturnFee's code actually does
Signing up through okx.com/join/RETURNFEE attributes your account to ReturnFee's own affiliate program on OKX. From there:
- OKX's own discount applies automatically the moment your account is attributed, with or without any further step.
- ReturnFee's own share is paid on top, after you register your OKX UID.
- Total: up to 60% of the trading fee your account pays, back to you.

OKX's real fee, read from its own page
| Symbol | Maker | Taker | Source | Read |
|---|---|---|---|---|
| BTC/USDT perpetual, standard tier (VIP 0) | 0.020% | 0.050% | OKX fee schedule | 2026-10-18 |
Rate read from OKX's own published fee-schedule page, verified 2026-10-18. The taker rate applies to most retail order flow; the maker rate is lower and applies to resting limit orders.
What 60% is worth in dollars
At $50,000 in monthly OKX futures volume, entirely at the taker rate of 0.050%:
- Fee paid to OKX: $50,000 × 0.050% = $25.00 that month.
- Total back: $15.00, 60% of the $25.00 in fees that month, paid partly automatically by OKX and the rest by ReturnFee.
The percentage is fixed by ReturnFee's own published rebate offer; the dollar amount moves with your own trading volume, not with any promise about returns.
