The two most fundamental product types in Binance Earn are "Flexible" and "Locked" Savings. Many beginners aren't sure how they differ or which to choose. It's actually quite simple — the core difference boils down to one thing: flexibility.
Flexible Savings: Withdraw Anytime, Lower Yield
Key features of Flexible Savings:
- Subscribe and redeem anytime — funds typically return to your account within minutes
- Annual Percentage Yield (APY) is relatively low, with USDT generally in the 1%–3% range
- Interest is calculated and distributed daily
- No lock-up period — your funds are completely liquid
Best for: You have some crypto sitting idle that you're not actively trading. Instead of leaving it doing nothing, drop it into Flexible Savings to earn some interest. When you need it, pull it right back out — no restrictions at all.
Locked Savings: Lock It Up, Earn More
Key features of Locked Savings:
- Funds are locked for a fixed number of days, with common terms of 30, 60, 90, and 120 days
- APY is noticeably higher than Flexible — the same USDT might earn 3%–6%
- Cannot be redeemed during the lock-up period (some products allow early redemption, but earned interest will be forfeited)
- Principal and interest are automatically returned to your spot account at maturity
Best for: You know you won't need certain funds for a while and are willing to trade time for higher returns. For example, if you plan to hold BNB long-term, locking it up for 90 days to earn interest beats just letting it sit.
Side-by-Side Comparison
| Feature | Flexible Savings | Locked Savings |
|---|---|---|
| Redemption | Anytime | After maturity |
| Yield | Lower | Higher |
| Flexibility | High | Low |
| Risk | Very low | Very low |
| Best for | Users needing liquid funds | Long-term holders |
Auto-Subscribe Feature
Binance has an "Auto-Subscribe" feature. When enabled, idle crypto in your spot account is automatically moved into Flexible Savings to earn interest, and it's automatically redeemed when you need to trade. Think of it like a "sweep account" at a bank — very convenient.
In the Binance App, go to "Earn" → "Flexible," find the coin you want, and when subscribing, you can check the "Auto-Subscribe" option.
Practical Advice
If you're unsure, start with Flexible. Put your idle USDT or BNB into Flexible and experience the daily interest hitting your account. Once you're confident that certain funds won't be needed for a few months, move them into Locked Savings for the higher rate.
You can use both products at the same time — keep some in Flexible for liquidity and put the rest in Locked for better yields. This combination strategy is by far the most common approach in practice. Sign up for Binance and tap "Earn" on the app homepage to get started.
