CD Compound Interest Calculator – Accurately Estimate Your Certificate of Deposit Returns

Are you investing in a Certificate of Deposit (CD) and want to know how compound interest will grow your money? Use our CD Compound Interest Calculator to calculate your earnings, maturity value, and total interest in just seconds.

Whether you’re saving for retirement, education, or a big purchase — this tool gives you a clear picture of your future wealth based on interest compounding.

💡 What Is Compound Interest in a CD?

Unlike simple interest, compound interest adds earned interest back to the principal at regular intervals — allowing you to earn interest on interest.

In a Compound Interest CD, your deposit grows faster because:

• Interest is compounded (monthly, quarterly, yearly, etc.)
• You don’t withdraw your earnings during the CD term
• You hold the CD until maturity

More compounding periods = more total return.

🔧 How to Use the CD Compound Interest Calculator

This tool is easy to use — even if you’re new to investing:

1. Enter the Deposit Amount (Principal)
   Example: ₹1,00,000 or $5,000
2. Enter Annual Interest Rate (%)
   Example: 7.5%
3. Select CD Term (Years or Months)
   Example: 2 years or 24 months
4. Choose Compounding Frequency
   Options: Annually, Semi-Annually, Quarterly, Monthly, or Daily
5. Click “Calculate”
   Instantly see:
   • Total Interest Earned
   • Final Maturity Amount (Principal + Interest)

🧮 Formula Used

Our calculator is based on the standard compound interest formula:

Maturity Amount = P × (1 + r/n)^(nt)

Where:

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

Total Interest = Maturity Amount – Principal

🧠 Example

Invest ₹1,00,000 in a 2-year CD at 7% compounded quarterly:

Maturity Amount = ₹1,00,000 × (1 + 0.07/4)^(4×2)  
                ≈ ₹1,14,973.70

Total Interest = ₹14,973.70

Your money grows by nearly ₹15,000 in 2 years — risk-free!
