Frequently Asked Questions
Clear explanations of compounding frequency, FDIC safety, and interest taxation.
Why do traditional big banks pay only 0.01% on savings?
Traditional brick-and-mortar banks have high physical overhead costs (branch rents, tellers, ATMs) and enjoy massive captive depositor bases. Because they do not need to compete aggressively for deposits, they keep savings rates near zero to maximize their own profit margins.
How much more does an HYSA pay than a traditional bank on $20,000?
On a $20,000 deposit with $300/mo additions over 5 years, a 4.5% HYSA earns approximately $7,021 in interest, while a 0.01% traditional bank earns only $14. The HYSA delivers over $7,000 in additional wealth.
Is it difficult to transfer money between an online HYSA and a traditional checking account?
Not at all. You can easily link your traditional checking account to your online HYSA via electronic ACH. Transfers typically complete in 1 to 2 business days, and many institutions now offer same-day ACH transfers.
