📌 Terms of the Referral Program:
- The sign-up bonus is calculated based on net deposits made within the first 365 days after your initial deposit.
- Only new clients opening an individual or joint account are eligible.
- Earned shares cannot be sold or transferred for one year.
- You must maintain an average balance for at least one year for your bonus shares to fully vest (details below). 👇
What Is an Average Balance and How Does It Work?
Your average balance is determined by your total deposits and the value of your portfolio over a given period. This includes both cash deposits and all assets, such as stocks and other securities. Bonus shares are credited to your account, but you cannot trade, transfer, or withdraw them until you meet the requirement of maintaining an average balance for one year (the vesting period). Interactive Brokers monitors your account value daily (cash deposits + investments). At the end of the one-year period, it calculates your average balance over 365 days, most likely using an arithmetic average.
Bonus shares are allocated based on this average balance:
- $1 in IBKR shares is awarded for every $100 of average balance.
- If you deposit a large amount for only a short period (e.g., $100,000 on day 365), your average balance will be much lower, as your account remained low or empty for most of the year. See scenarios below…
Scenario #1:
- First deposit: $10,000.
- Balance maintained throughout the year with no withdrawals.
- Average balance: $10,000.
- Bonus: $100 in shares.
Scenario #2:
- First deposit: $1.
- Second deposit: $100,000 on the 364th day after the first deposit.
- Balance for most of the year: $1.
- Average balance: (1 × 365 days + 100,000 × 1 day) / 365 = $274.97.
- Bonus: $2.75 in shares
I hope I’ve explained the concept of IB’s average balance for the bonus as clearly as possible.
When Will I Receive My IBKR Bonus Shares, and Where Can I Track Them?
Bonus shares are typically credited to your account on the next trading day after your deposit is processed (see details below).
For example, in the screenshot, a deposit was credited to IB’s account via electronic fund transfer on November 1, 2023. The next day (November 2, 2023 – award day), 0.3794 fractional shares were credited. These shares remained locked until November 1, 2024 (vesting day).
