Understanding the Formula Behind CD Growth
The calculator uses standard financial formulas to determine accurate returns.
1. Compound Interest Formula
The core formula used is:A=P×(1+nr)nt
Where:
- A = Final amount
- P = Principal (initial deposit)
- r = Annual interest rate (decimal form)
- n = Compounding frequency per year
- t = Time in years (14 months = 14/12 years)
Interest Earned:
Interest=A−P
2. APY (Annual Percentage Yield) Formula
APY shows the real annual return including compounding.APY=(1+nr)n−1
This helps compare different CD products fairly.
Example Calculation (Real-Life Scenario)
Let’s understand how the calculator works with a real example.
Scenario:
- Initial Deposit: $5,000
- Interest Rate: 4.5%
- Compounding: Monthly
- Term: 14 months
Step-by-Step Result:
| Metric | Value |
|---|---|
| Initial Deposit | $5,000.00 |
| Interest Earned | $265.92 |
| Total Value | $5,265.92 |
| Effective APY | 4.59% |
Explanation:
- Your money grows gradually due to compound interest
- Monthly compounding increases returns slightly
- Even a small rate difference impacts total earnings over time
