CD Calculator – Estimate Your Certificate of Deposit (CD) Interest Instantly!

Want to know how much interest you’ll earn by investing in a Certificate of Deposit (CD)? Our CD Calculator Interest Tool helps you calculate total earnings and maturity value in seconds — so you can make smarter, more profitable saving decisions.

Whether you’re saving for a vacation, retirement, or just building a secure future, this tool simplifies your financial planning.

💡 What Is a Certificate of Deposit (CD)?

A Certificate of Deposit (CD) is a secure, interest-bearing savings product offered by banks and credit unions. You deposit a fixed amount of money for a set time (term), and in return, you earn a guaranteed interest.

Key features of CDs:

• Fixed term (e.g., 6 months, 1 year, 5 years)
• Fixed interest rate
• Higher returns than regular savings accounts
• Penalties for early withdrawal

🔧 How to Use the CD Calculator Interest Tool

Using our CD calculator is fast and beginner-friendly. Follow these simple steps:

1. Enter Deposit Amount (Principal)
   Example: ₹50,000 / $5,000
2. Enter Annual Interest Rate (%)
   Example: 6.75%
3. Enter Term (in months or years)
   Example: 12 months or 2 years
4. Select Compounding Frequency
   Options: Annually, Semi-Annually, Quarterly, Monthly, Daily
5. Click “Calculate CD Interest”
   The tool instantly shows:
   • Total Interest Earned
   • Maturity Value (Principal + Interest)

🧮 How the Calculation Works

The tool uses compound interest to calculate returns:

Maturity Amount = P × (1 + r/n) ^ (nt)

Where:

• P = Principal (initial deposit)
• r = Annual interest rate (decimal)
• n = Number of compounding periods per year
• t = Time in years

Total Interest = Maturity Amount – Principal

🧠 Example Calculation

Let’s say you invest ₹1,00,000 in a 2-year CD at 7% annual interest compounded monthly:

Maturity Value = ₹1,00,000 × (1 + 0.07/12) ^ (12×2)  
               = ₹1,14,974.28

Total Interest = ₹14,974.28

That’s nearly ₹15,000 earned with zero risk!
