CD & Savings Calculator

Our CD and savings calculator uses the compound interest formula to project exactly how your money grows over time. Whether you are comparing CD rates or building an emergency fund, this tool gives you the real numbers — not inflated bank marketing promises.

What This Calculator Shows

• Final Balance: Total value at maturity, including all deposits and interest
• Total Interest Earned: How much your money made while sitting in the account
• Effective Annual Yield (APY): The real annualized return accounting for compounding frequency — often slightly higher than the stated rate
• Rate Comparison Table: See side-by-side what happens at 3%, 4%, 5%, 6%, and 7% APY for the same term and deposits

CD vs High-Yield Savings: What's the Difference?

• CDs (Certificates of Deposit): Fixed rate, fixed term. You lock money away for 3-60 months. Typically higher rates than savings, but early withdrawal penalties apply.
• High-Yield Savings: Variable rate, no term commitment. Access money anytime. Rates fluctuate with the Fed — great for emergency funds.
• CD Laddering: Split your deposit across multiple CDs with staggered maturities. You get higher CD rates plus regular access to portions of your money.

Why Compounding Frequency Matters

A 5% APY with daily compounding yields an effective annual yield of about 5.13% — meaning $10,000 grows to $10,513 in one year instead of exactly $10,500 with simple interest. The difference seems small in one year, but over 5+ years with ongoing contributions, daily compounding can add hundreds of extra dollars.
