Understanding APY & Compounding

How It Works

Uses the compound interest yield equation APY = (1 + r/n)^n - 1 to calculate total annual interest yield earned.

How to Use

1. Input the nominal annual interest rate. 2. Select the compounding interval (Daily, Monthly, Quarterly, Semi-Annually, Annually). 3. View effective APY.

Understanding the Results

APY indicates true annual return taking compounding into account. Higher compounding frequencies yield higher APY.

APY FAQ

FAQ

Does daily compounding significantly increase yield?

Daily compounding yields slightly more than monthly compounding, maximizing the growth of interest earned on interest.

Should I compare savings offers using nominal rate or APY?

Always use APY when comparing savings accounts or CDs, as APY accounts for compounding frequency differences.
