Annual Percentage Yield (APY) is how much compound interest you will earn in a year. Our Simply Savings pays interest with each statement cycle. With rates higher than the FDIC national average savings rate, you can enjoy CD level interest rates without being locked into a lengthy term.
Some high-yield savings accounts require an opening deposit of $10,000 or more. You can open a Simply Savings with us for just $100 and start earning more in just 15 minutes! Open your account here.
Other high-yield savings accounts require a certain minimum balance to earn the higher APY and avoid service fees. With Simply Savings, you can avoid a low balance fee by maintaining a $100 Average Available (collected) Balance (AAB) in your account. Also earn a great interest rate on all balances based on the Available (collected) Balance (AB).
Don’t be restricted from using your money when you need it! You can withdrawal from your Simply Savings up to 6 times per statement cycle without a fee.**
| Tier Level | Account Funds | Simply Savings Interest Rate(2) | APY (Annual Percentage Yield) Ranges |
|---|---|---|---|
| Tier 1 | up to $500.00 | 2.00% | 2.02% |
| Tier 2 | $500.01 – $25,000.00 | 2.00% | 2.02 to 2.02% |
| Tier 3 | $25,000.01 – $50,000.00 | 0.75% | 2.02 to 1.39% |
| Tier 4 | $50,000.01 – $100,000.00 | 0.80% | 1.39 to 1.09% |
| Tier 5 | $100,000.01 – $200,000.00 | 0.85% | 1.09 to 0.97% |
| Tier 6 | $200,000.01 – $1,000,000.00 | 0.90% | 0.97 to 0.92% |
Example 1, you deposit $1,000 into a Simply Savings, you earn 2.00% interest on all of your funds, so your APY interest rate on your statement will show as 2.02%.
Example 2, you deposit $30,000 into a Simply Savings account you will earn 2.00% interest on the first $25,000. You will then earn 0.75% on the other $5,000 that you deposited. Therefore, when you see the APY interest rate on your statement, it will show as 1.80%.
Example 3, you deposit $90,000 into a Simply Savings. You will earn 2.00% interest on the first $25,000; 0.75% on the next $25,000; 0.80% on the final $40,000. Therefore when you see the APY interest rate on your statement, it will show as 1.13%
(1) on your first $25,000.00
(2) Rates are subject to change after opening the account. Fees assessed may reduce earnings on the account.
(3) The interest for this account is based on variable rates for each “Split Balance” tier. Interest will be paid on a Split Balance rate calculation method: When split balance rates are used, the portion of an account’s Available (Collected) Balance (AB) which is less than or equal to the first split balance amount earns interest on the first rate tier. The portion of an account’s (AB) which is less than or equal to the second split balance amount earns interest at the second rate tier. The portion of an account’s (AB) which is less than or equal to the third split balance amount earns interest at the third rate tier, and so on up to a maximum of six split balance amounts and six split interest rate tiers (shown above “Simply Savings Split Balance Tiers). The interest rate and overall Annual Percentage Yield (APY) will depend on the (AB) in the account according to the rate tier applied to each portion of the account balance. Interest is calculated daily based on the (AB) in the account for each individual day. Daily interest totals are then combined and applied to the account as a single interest total at the end of the statement period.
(4) A $2.00 Low Balance Service Fee is charged when the Average Available (Collected) Balance (AAB) is below $100.00 for the statement cycle. (P5)(P7)
(5) The (AAB) is calculated by adding the available principal balance in the account for each day of the period and dividing that figure by the number of days in the period.
(7) The available balance is the account balance, less unpaid deposited items drawn on other financial institutions in the process of collection.
