High-Yield Savings (HYSA)
Earn $400/year on $10K instead of $1.
Quick math
$10,000 sitting in Bank of America savings = $1/year (0.01% APY). Same $10,000 in Ally Bank = $420/year. Most people leave $300-500/year on the table because they've never moved their savings.

How to open one
- Pick a bank (Ally is most senior-friendly).
- Go to bank's website. Click "Open an Account".
- Fill in name, address, SSN, email, phone.
- Link to existing checking account at any bank.
- Bank verifies via 2 small "test" deposits ($0.04 + $0.07).
- Confirm amounts back. Done.
- Transfer money in. Earns interest immediately.
Keep checking at your old bank
Don't move your CHECKING — keep that at your local bank. HYSA is just for savings. Transfers between them take 1-3 days. Set up auto-transfer monthly to "save without thinking".
Watch the rate
High-yield rates change with Fed rates. 4.5% today, could be 3% next year, 5% the year after. Check rates every 6 months. Switching banks is annoying but possible. Or just open a CD if rates start dropping (locks rate for 6-24 months).
