What is CD Calculator?
A Certificate of Deposit (CD) is a savings product that offers a fixed interest rate over a specified period. This CD calculator helps you determine the future value of your CD, including the total interest earned, by considering the principal amount, annual interest rate, number of years, and the frequency of compounding. It's a valuable tool for investors looking to estimate the growth of their investment over time.
Understanding the Calculation
The CD calculator uses the compound interest formula to determine the future value of your investment. Compound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods. The formula used is:
Future Value = Principal × (1 + (Interest Rate / n))(n × Years)
Where:
- Principal is the initial amount of money invested.
- Interest Rate is the annual interest rate (as a decimal).
- n is the number of times that interest is compounded per year.
- Years is the number of years the money is invested for.
CD Calculation Formula
FV = P × (1 + r/n)(nt)
Where:
- FV = Future Value of the CD
- P = Principal Amount (initial investment)
- r = Annual Interest Rate (as a decimal)
- n = Number of times interest is compounded per year
- t = Number of years
Example: For a $1,000 principal, 5% annual interest rate, compounded quarterly, over 2 years:
FV = $1000 × (1 + 0.05/4)(4*2) ≈ $1104.49
Understanding Your Results
The calculator provides two main results: the Future Value and the Total Interest.
- Future Value: This is the total amount you will have at the end of the CD's term. It includes both the original principal and the accumulated interest. This shows the overall growth of your investment.
- Total Interest: This is the total amount of interest earned over the term of the CD. It represents the difference between the future value and the initial principal. This indicates how much your money has grown due to the effect of compounding.
These results help you understand the profitability of your CD investment and compare different CD options or other investment opportunities.
