Formula Used
The calculator uses the following formula to calculate CD interest:
Where:
- Principal is the initial amount of money you deposit.
- Annual Interest Rate is the percentage rate offered by the bank.
- Term Length is the duration of the CD in months.
Note: This calculator assumes simple interest compounded monthly. For more complex scenarios, consult a financial advisor.
Worked Example
Let's say you deposit $5,000 in a CD with a 2.5% annual interest rate for 12 months. Here's how the calculation works:
Example Calculation
Final Amount = $5,000 × (1 + (2.5 / 100))^(12 / 12) = $5,000 × 1.025 = $5,125
Total Interest = $5,125 - $5,000 = $125
Monthly Interest Rate = 2.5% / 12 ≈ 0.208%
This means you would earn $125 in interest over the 12-month period, resulting in a final amount of $5,125.
CD Rate Comparison
Compare different CD terms and rates to find the best option for your savings goals:
| Term (Months) | 1% Rate | 2% Rate | 3% Rate | 4% Rate |
|---|---|---|---|---|
| 6 | $100.00 | $200.00 | $300.00 | $400.00 |
| 12 | $200.00 | $400.00 | $600.00 | $800.00 |
| 24 | $400.00 | $800.00 | $1,200.00 | $1,600.00 |
| 36 | $600.00 | $1,200.00 | $1,800.00 | $2,400.00 |
