Compound Interest Formula Explained
The calculator uses the standard compound interest formula:
A = P (1 + r/n)^(n × t)
Where:
- A = Final amount
- P = Principal (initial deposit)
- r = Annual interest rate (decimal)
- n = Compounding periods per year
- t = Time in years
Step-by-Step Breakdown
- Convert interest rate into decimal
r = rate ÷ 100 - Divide interest rate by compounding frequency
r/n - Add 1 to the result
(1 + r/n) - Multiply compounding periods and time
n × t - Apply exponent to calculate growth
(1 + r/n)^(n × t) - Multiply by principal to get final value
Interest Earned Formula
Interest = Final Amount − Principal
Example Calculation
Let’s understand with a real example:
- Principal = $10,000
- Rate = 5%
- Time = 3 years
- Compounding = 12 times per year
Step 1: Apply formula
A = 10000 (1 + 0.05/12)^(12×3)
Step 2: Result
- Final Amount ≈ $11,616.00
- Interest Earned ≈ $1,616.00
This shows how compound interest increases savings over time.
Example Table of CD Growth
| Principal ($) | Rate (%) | Years | Compounding | Final Amount ($) | Interest Earned ($) |
|---|---|---|---|---|---|
| 1,000 | 3 | 2 | 12 | 1,061 | 61 |
| 5,000 | 4 | 3 | 12 | 5,624 | 624 |
| 10,000 | 5 | 3 | 12 | 11,616 | 1,616 |
| 15,000 | 4.5 | 5 | 4 | 18,653 | 3,653 |
| 20,000 | 6 | 4 | 1 | 25,280 | 5,280 |
Understanding Compounding Frequency
Compounding plays a huge role in how much interest you earn.
Common Types:
- Monthly (12 times/year): Faster growth
- Quarterly (4 times/year): Moderate growth
- Yearly (1 time/year): Slowest growth
The more frequently interest is compounded, the higher your return.
