Future Value: Not Calculated Yet

The Future Value Calculator helps you estimate how much your investment will grow over a specified period. By considering initial investments, monthly contributions, interest rates, and time, this tool provides insights into the power of compounding and helps you plan your financial future effectively.

Future Value Formula

The calculator uses the following formula to compute future value:

$Future Value = P \times {(1 + r)}^{n} + \frac{PMT \times {(1 + r)}^{n} - 1}{r}$

Where:

P: Initial investment
PMT: Monthly contribution
r: Monthly interest rate (Annual Rate ÷ 12 ÷ 100)
n: Total months (Years × 12)

Why Use This Calculator?

This calculator is ideal for:

Financial Planning: Understand the potential growth of your investments over time.
Goal Setting: Determine how much to save monthly to reach your financial goals.
Compounding Insights: Visualize how interest earnings accelerate over time.

Real-Life Example

Consider the following scenario:

Initial Investment: $5,000
Monthly Contribution: $200
Annual Interest Rate: 5%
Investment Period: 10 years

Step 1: Convert the annual interest rate to a monthly rate:

$r = \frac{5}{12} \div 100 = 0.004167$

Step 2: Calculate total months:

$n = 10 \times 12 = 120$

Step 3: Apply the formula:

$Future Value = 5000 \times {(1.004167)}^{120} + \frac{200 \times {(1.004167)}^{120} - 1}{0.004167}$

Result: After 10 years, your investment will grow to approximately $40,748.91.
