Frequently Asked Questions
Why does my bank pay so little interest?
Big traditional banks (Chase, Bank of America, Wells Fargo) pay low rates (0.01-0.10% APY) because they don’t need to compete for deposits—they have massive customer bases. Online banks have lower overhead and must compete on rates to attract customers.
How often is interest paid to my account?
Most banks calculate interest daily but pay it monthly. You’ll see a deposit at month’s end. Some banks pay quarterly. Check your statement for the exact schedule. Interest compounds even if paid monthly.
Is my savings account FDIC insured?
Most bank savings accounts are FDIC insured up to $250,000 per depositor, per bank. Credit unions use NCUA insurance (same limit). Online banks like Marcus, Ally, and Discover are all FDIC insured—this is not a downside of high-yield accounts.
Will savings rates go down?
Savings rates follow the Federal Reserve’s interest rate decisions. When the Fed raises rates, savings APYs typically rise. When the Fed cuts rates, savings APYs fall. High-yield accounts usually maintain a competitive advantage over traditional banks regardless.

Bottom line: If you have $10,000+ in savings at a big bank earning 0.10% APY, you’re losing hundreds of dollars per year. Moving to a high-yield savings account at 4.50% APY takes 10 minutes and is completely safe (FDIC insured). Don’t leave money on the table.
