On the Flexible products page, you often see both "Real-Time APR" and "Bonus APR" displayed side by side. Many people assume that adding the two gives the total return. In reality, these two earnings differ completely in terms of interest calculation, payout frequency, and the wallet where they are credited — Real-Time APR is calculated per minute and accumulates directly into the Earn Wallet, while Bonus APR is calculated based on daily snapshots and distributed to your Spot Wallet the next day.
Below is a detailed breakdown of the rules and calculation methods for these two earnings.
Step 1: Understand the Definitions and Sources of the Two APRs
Real-Time APR and Bonus APR correspond to two independent reward mechanisms.
What to do: Understand what each APR represents and where it comes from.
How to do it:
Real-Time APR:
Reflects the instant indicator of your current earning potential; it can change every minute.
The yield comes from the interest generated when your assets are lent to other users through Margin and Loan products.
A higher APR usually indicates a higher utilization rate of the asset being lent out, meaning strong borrowing demand.
This APR applies to the total amount you have deposited in that particular Flexible product.
Bonus Tiered APR:
This is an extra reward offered by Binance for specific Flexible products.
It typically uses a tiered rate structure, offering different APR levels based on the amount deposited.
This APR can also change daily.
Some products offer Bonus APR for a limited promotional period; after the promotion ends, only the Real-Time APR will remain.
When you're done: You understand that Real-Time APR is the base lending interest, and Bonus APR is an additional platform subsidy, and the two are independent of each other.
Common mistake: Directly adding the two percentages together and thinking they equal the "total APR," ignoring the differences in interest calculation cycles and crediting methods.
Step 2: Break Down the Calculation and Distribution of Each Type of Earnings
This is the part most people get confused about — the two types of earnings have different calculation timing, distribution schedules, and receiving wallets.
What to do: Track the calculation and arrival details of each type of earnings separately.
How to do it:
| Comparison | Real-Time APR Earnings | Bonus Tiered APR Earnings |
|---|---|---|
| Calculation frequency | Calculated per minute and accumulated directly | Based on a daily snapshot taken randomly between 00:00–23:59 UTC |
| Start of interest accrual | Begins immediately after subscription; earnings start from the next minute | Accumulation starts from 00:00 UTC the next day after subscription |
| Crediting time | No separate distribution record; directly increases the Earn Wallet balance | Credited the day after accumulation starts (i.e., the 3rd day after subscription) between 00:00–08:00 UTC |
| Crediting wallet | Earn Wallet (increases the Flexible product balance of that token directly) | Spot Wallet |
| Earnings precision | Unconditionally truncated to 8 decimal places | Calculated normally |
Formula reference:
Real-Time APR earnings = Deposit Amount × Real-Time APR ÷ 365 ÷ 24 ÷ 60 (credited per minute)
Bonus Tiered APR earnings = Previous day's snapshot amount × applicable tiered bonus rate ÷ 365 (calculated daily)
When you're done: You know that to see Real-Time earnings you check the balance change in your Earn Wallet, and for Bonus earnings you check your Spot Wallet or the Earn History for distribution records.
Prerequisite: Bonus APR calculation is based on a random snapshot of the previous day between 00:00–23:59 UTC. If you redeem assets before that day's snapshot, the redeemed portion may not be counted for that day's Bonus APR earnings.
Risk note: After redeeming from a Flexible product, Bonus APR earnings on the redeemed amount will stop accruing for that day. If you plan to redeem, it is recommended to do so after the snapshot time (within the UTC window).
Step 3: Verify Your Earnings Using Actual Holdings
Once you understand the rules, use your actual holdings data to verify whether the earnings you receive match your expectations.
What to do: Take the Real-Time APR and Bonus APR of one of your Flexible holdings, calculate the expected daily earnings, and compare them with the actual amounts credited.
How to do it:
In [Earn] - [Flexible Products], find the product you hold and note the current "Real-Time APR" and "Bonus APR" values.
Based on the amount held in that product:
Estimated daily Real-Time earnings ≈ Holding Amount × Real-Time APR ÷ 365
Estimated daily Bonus earnings ≈ Holding Amount × Bonus APR ÷ 365
Check two places the next day:
Whether the balance of that product in your Earn Wallet has increased compared to the previous day (for Real-Time earnings).
Whether there is a corresponding reward distribution record in your Spot Wallet or [Earn History] (for Bonus earnings).
When you're done: You can distinguish the arrival time and wallet for each type of earnings and roughly verify whether the amounts are consistent with your holdings data.
How to Confirm You've Done It Correctly?
After verifying your earnings, check two things:
Check the [Earn History]; you will see a separate distribution record for "Tiered APR Rewards," while "Real-Time APR earnings" will not have a separate distribution record because they are directly added to your Earn Wallet balance.
If you have just subscribed to a product, the Bonus Tiered APR earnings will only be credited for the first time on the third day. It is normal not to see this earnings on the first and second days.
If the credited amount deviates significantly from your expectations, check whether a redemption caused the Bonus APR earnings to stop accruing, or whether there is a promotional time limit on the product's Bonus APR.
