*APY = Annual Percentage Yield
| Balance | APY* |
|---|---|
| $100 – $2,499 | 0.05% |
| $2,500 – $9,999 | 3.01% |
| $10,000+ | 4.01% Best Rate |
| Protect your rate for 180 days!** | |
*Annual Percentage Yield (APY) may change at any time. This is a variable-rate, tiered savings account. The APY you earn depends on your account balance and applies to the entire balance within the applicable tier: 0.05% APY for balances of $100–$2,499.99, 3.01% APY for balances of $2,500–$9,999.99, and 4.01% APY for balances of $10,000 or more.
**180-Day Rate Protection: Newly opened Digital HYSA accounts receive a 180-Day Rate Protection Period beginning on the account opening date. During this period, your account will continue to receive the APYs and balance tiers in effect when the account was opened. As your balance changes, you may move between balance tiers and earn the APY associated with the applicable tier. If APYs increase during the 180-Day Rate Protection Period, your account will receive the benefit of the higher rates. After the 180-Day Rate Protection Period ends, your account will earn the APYs applicable to the then-current balance tiers in effect at that time.
Additional Information: Interest is calculated using the daily balance method, compounded monthly, and credited monthly. A minimum balance of $100 is required to earn dividends. Fees and transaction limits may apply and could reduce earnings. See the Account Agreement for complete terms and conditions.
