This free online tool helps you determine the final balance, interest earned, and maturity date based on your deposit, interest rate, compounding frequency, and term length.

CD Maturity Calculator
🚀 What is a CD Maturity Calculator?
A CD Maturity Calculator is a financial tool designed to help users compute the total value of a Certificate of Deposit upon its maturity. It takes into account several variables such as:
- Initial deposit amount
- Annual interest rate
- Term length in months
- Compounding frequency (daily, monthly, quarterly, etc.)
Using these inputs, the calculator provides key results like:
- Final balance
- Total interest earned
- Maturity date
🧮 How Does It Work?
The calculator uses the compound interest formula:
A = P × (1 + r/n)^(nt)
Where:
- A = Final amount (maturity value)
- P = Principal (initial deposit)
- r = Annual interest rate (decimal)
- n = Number of compounding periods per year
- t = Time (in years)
It also computes the maturity date by adding the number of months entered as the term to the current date.
🛠️ How to Use the CD Maturity Calculator
Follow these easy steps:
- Enter Initial Deposit – Input the amount you plan to deposit.
- Input Annual Interest Rate – Enter your CD’s interest rate (e.g., 4.5).

📘 Example Calculation
Let’s say you invest $10,000 at an interest rate of 5% per annum, for 24 months, compounded monthly.
- Principal (P): $10,000
- Interest Rate (r): 5% or 0.05
- Term (t): 2 years
- Compounding Frequency (n): 12 times a year (monthly)
Final Balance (A):
A = 10,000 × (1 + 0.05/12)^(12×2)
A ≈ $11,048.99
Interest Earned: $1,048.99
Maturity Date: 2 years from today
