💡 What Is a CD (Certificate of Deposit)?

A CD is a time-based savings product offered by banks and credit unions. You deposit a fixed amount of money for a specific term (like 6 months, 1 year, or 5 years) and earn a guaranteed interest rate.

Why people love CDs:

• Safe and low-risk
• Fixed interest rate
• Predictable returns
• Ideal for both short-term and long-term savings

   • 🏦 Maturity Amount (Principal + Interest)

🧮 Behind the Scenes – Formula Used

We calculate returns using the compound interest formula:

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

Where:

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

Interest Earned = Maturity Amount – Principal

🧠 Example Calculation

You invest ₹1,00,000 in a 3-year CD at 7.5% interest compounded monthly.

The calculator shows:

• Interest Earned: ₹24,336.62
• Maturity Value: ₹1,24,336.62

That’s a risk-free return, with zero market volatility.
