Banking, Savings & Yield
Stop leaving four percentage points on the table.
Cash is the one part of a financial plan where a better outcome requires no additional risk and no ongoing effort — only a single transfer to a higher-yielding, equally insured account.
These tools quantify the difference across compounding frequencies, terms and tax treatments so the size of the gap is concrete rather than abstract.

Banking & Savings questions
What is the difference between APY and interest rate?
The interest rate is the simple annual rate. APY includes the effect of compounding within the year, so it is always equal to or higher than the stated rate. Comparing accounts by APY is the only apples-to-apples comparison, which is why US institutions are required to disclose it.
Are high-yield savings accounts safe?
Yes, when the institution is FDIC-insured — or NCUA-insured for credit unions — and your balance stays within the $250,000 per depositor, per institution, per ownership category limit. Online banks offer higher rates because they have no branch network, not because they take more risk with your deposits.
Is a CD better than a high-yield savings account?
A CD locks the rate for a fixed term, which protects you if rates fall, at the cost of liquidity and an early withdrawal penalty. A savings account rate floats with the market. When rates are expected to decline, locking a CD is attractive; when they are rising or you may need the money, savings wins. Never put an emergency fund in a CD.
Do I pay tax on savings account interest?
Yes. Interest is taxed as ordinary income at your marginal federal rate, plus state tax where applicable, and is reported on Form 1099-INT if it exceeds $10. A 4.5% APY at a 24% federal marginal rate is closer to 3.4% after tax — which is why the after-tax, after-inflation return on cash is frequently near zero.
