Did You Know?
How Does Savings Interest Work?
APY Formula
APY = (1 + APR/n)^n - 1
Where n = compounding frequency per year. A 5% APR compounded monthly = (1 + 0.05/12)^12 - 1 = 5.12% APY.
Interest Earned
Interest = Principal × (1 + rate/n)^(n×t) - Principal
Example: $10,000 at 5% for 5 years, monthly compounding: $10,000 × (1.004167)^60 - $10,000 = $2,833.59.
Effective Rate Comparison
More frequent compounding yields higher effective returns. Daily compounding beats monthly, which beats annual.

What is APY vs APR?
APY (Annual Percentage Yield) includes compound interest. APR does not. A 5% APR compounded monthly = 5.12% APY. APY is always higher than APR for the same nominal rate.
How does compounding frequency matter?
$10,000 at 5%: Annual = $500, Monthly = $511.62, Daily = $512.67. The difference grows significantly over longer periods and higher rates. More frequent compounding = more interest.

Interest income is taxed as ordinary income (federal + state). At 22% federal + 5% state, you keep only 73 cents of every dollar earned in interest. Tax-advantaged accounts (IRA, 529) avoid this.

$250,000 per depositor, per bank, per ownership category. Joint accounts get $500K coverage. Spread deposits across banks if you exceed limits. Credit unions have NCUA insurance (same limit).
