Calculation Estimations vs. Bank Statements

While our algorithms adhere to standard compound interest calculations (A = P(1 + r/n)^(n×t) and APY yield formulas), actual earnings credited by financial institutions may differ marginally due to:

Specific bank calendar conventions (Actual/365, Actual/360, or 30/360).
Leap year adjustments and fractional interest crediting days.
Tax withholding, federal or state income tax obligations on interest earned.
Tiered interest rates or minimum balance thresholds.

Early Withdrawal Penalties

Most Certificate of Deposit agreements mandate an early withdrawal penalty if principal is redeemed prior to the agreed maturity date. These penalties can forfeit several months of interest earnings and, in certain circumstances, diminish initial principal. Always consult your bank or credit union's deposit agreement before opening an account.

Deposit Insurance (FDIC & NCUA)

FDIC deposit insurance up to $250,000 applies strictly to qualifying accounts held at FDIC-insured banks. Credit union share certificates are insured under the NCUA. We encourage savers to verify insurance status directly with their prospective banking institution.
