Compound Interest Curve Chart
This chart compares the growth of your investment under two scenarios. Scenario A represents the growth based on your inputted interest rate. Scenario B shows the potential growth with a 1% higher interest rate, demonstrating the potential difference due to a slight change in rates.
Note: Scenario B provides an illustrative comparison to show potential growth with a slightly higher interest rate.
Example Scenario For Compound Interest Calculation & Breakdown
Investment Details:
Initial Deposit (P): $10,000
Monthly Contribution: $200
Annual Interest Rate (r): 5%
Compounding Frequency (n): 12 (monthly)
Investment Period (t): 20 years
Calculation:
Using the compound interest formula:
A = P (1 + r/n)^(nt) + [Monthly Contribution × ((1 + r/n)^(nt) - 1) / (r/n)]
Plugging in the values:
A = 10000 (1 + 0.05/12)^(12*20) + 200 × [(1 + 0.05/12)^(12*20) - 1] / (0.05/12)
Result:
The future value of your investment after 20 years is approximately $109,333.14.
Summary
By starting with an initial deposit of $10,000, adding $200 monthly, at an annual interest rate of 5% compounded monthly, you can grow your investment to approximately $109,333.14 over 20 years.
