CD Calculator Online: Calculate Certificate of Deposit Earnings Easily
Introduction
A CD (Certificate of Deposit) Calculator is an essential online tool that helps savers estimate the interest earned on a CD over its term. CDs are fixed-term deposits offered by banks and credit unions, where you earn a guaranteed interest rate for a specified period.
This tool is perfect for individuals, retirees, and anyone looking to grow their savings safely. Using a CD calculator online allows you to plan your investments, compare rates, and calculate potential earnings without complex math.
Formula / Working
The CD Calculator typically uses the compound interest formula: A=P×(1+rn)n⋅tA = P \times \left(1 + \frac{r}{n}\right)^{n \cdot t}A=P×(1+nr)n⋅t
Where:
- AAA = Maturity amount (Principal + Interest)
- PPP = Principal amount (initial deposit)
- rrr = Annual interest rate (decimal)
- nnn = Number of compounding periods per year
- ttt = Number of years
Interest Earned: Interest=A−P\text{Interest} = A – PInterest=A−P
The calculator automatically computes your total earnings based on the deposit, rate, term, and compounding frequency.
