Understanding the Formula Used

Compound Interest Formula:
Where:
- A = Final Amount
- P = Principal (Initial Investment)
- r = Annual Interest Rate (in decimal form)
- n = Number of times interest is compounded per year
- t = Time in years
How Compound Interest Works
Compound interest means your investment grows on itself over time.
For example:
- You invest money
- You earn interest
- Next cycle, you earn interest on both money and previous interest
This creates a snowball effect, making long-term investing very powerful.
Example Calculation
Let’s understand with a simple example:
Scenario:
- Initial Investment (P): $5,000
- Annual Interest Rate (r): 6%
- Time Period (t): 10 years
- Compounding Frequency (n): Monthly (12 times per year)
Step 1: Apply Formula
Step 2: Result
- Final Amount ≈ $9,067.96
- Total Interest ≈ $4,067.96
Interpretation:
Your money almost doubles in 10 years due to compounding.
