Binance and OKX Earn Promotions Explained: Flexible vs Locked, Tiered APR and Boosts
On this page
Exchange earn products are where many people park idle funds: flexible products can be redeemed any time, locked products pay more, and on-chain products put assets into staking or protocols. Binance and OKX also run limited-time boosts and new-user rates. This guide explains the products and how much of an advertised APR you actually get.

- Flexible: subscribe and redeem any time; the rate floats.
- Locked/fixed: locked for a term, usually at a higher rate; early redemption is usually unavailable or forfeits interest.
- On-chain: assets go into staking or DeFi protocols; yield comes from the chain, with possible redemption waits and protocol risk.
Common promotion formats
- Tiered APR: for example a high rate on the first 500 USDT and the normal rate above that.
- Limited-time boosts: extra APR on certain products during a campaign, sometimes paid separately as vouchers.
- New-user rates: small, short, high-rate products for newcomers — see the new-user rewards guide.
- New-token earn: high-rate products paid in a newly listed token, with significant price risk.
- Holding rewards: hold or subscribe a given asset to share a pool, for example snapshot-based token distributions.
How much APR you really get
An advertised "20% APR" often applies only to a small tranche.
Example (illustrative numbers): a USDT flexible promotion pays 20% on the first 500 USDT and 3% above that. You subscribe 5,000 USDT:
- 500 × 20% = 100 USDT a year
- 4,500 × 3% = 135 USDT a year
- 235 USDT in total — an effective APR of only 4.7%.
Compare promotions by the boosted amount, the term and the base rate, not the headline APR. Products that accrue daily don't pay for days after you redeem.
The real risks
- Platform risk: assets are held by the exchange.
- Price risk: earning on BNB, ETH or new tokens exposes you to price drops far larger than the interest.
- Liquidity risk: locked and some on-chain products can't be withdrawn on demand.
- Rule risk: flexible rates change and promotions can end early or sell out.
FAQ
Binance Simple Earn: flexible or locked?
Use flexible for money you may need; locked for money you won't touch for the term. Both count toward HODLer Airdrop snapshots (subject to the products each announcement lists).
When is boosted interest paid?
Sometimes within the normal interest, sometimes separately as vouchers or rewards after the campaign — see the rules.
How is interest calculated?
Usually daily: interest = principal × APR ÷ 365 × days, with tiered rates calculated per tranche.
What's the difference between OKX Simple Earn and On-chain Earn?
Simple Earn is an exchange lending product; On-chain Earn puts assets into on-chain staking or protocols, with different sources of yield and risk.
