Understanding the Formula Behind the Calculator

This tool uses a combination of compound interest and future value of annuity formulas.

1. Future Value of Initial Investment

FV=P(1+r)tFV = P(1 + r)^tFV=P(1+r)t

PV is starting amount; r is rate; n is number of periods.

FV=PV(1+r)n=1(1+0.05)20=2653.3 dollarsFV = PV(1+r)^n = 1(1+0.05)^{20} = 2653.3\,\text{dollars}FV=PV(1+r)n=1(1+0.05)20=2653.3dollars

Where:

  • P = Initial investment
  • r = Annual return rate (decimal)
  • t = Time in years

This calculates how your lump sum grows over time with compounding.

2. Future Value of Monthly Contributions

FV=M((1+r)n−1r)FV = M \left( \frac{(1 + r)^n – 1}{r} \right)FV=M(r(1+r)n−1​)

Where:

  • M = Monthly contribution
  • r = Monthly interest rate
  • n = Total number of months

This calculates how your regular investments grow over time.

3. Total Future Value

Total future value is the sum of both components:

  • Initial investment growth
  • Monthly contribution growth

4. Profit Calculation

Profit=Future Value−Total Invested\text{Profit} = \text{Future Value} – \text{Total Invested}Profit=Future Value−Total Invested

This shows your actual earnings after subtracting what you invested.

Example Calculation

Let’s understand how the calculator works with a real-world example.

Scenario:

  • Initial Investment = $10,000
  • Annual Return = 8%
  • Time Period = 10 years
  • Monthly Contribution = $200

Step 1: Initial Investment Growth

Using compound interest:

$10,000 grows significantly over 10 years at 8%.

Step 2: Monthly Contributions

You contribute $200 every month:

  • Total contribution = $200 × 120 months = $24,000

These contributions also earn interest over time.

Step 3: Final Outcome (Approximation)

  • Future Value ≈ $58,000+
  • Total Invested = $34,000
  • Profit ≈ $24,000+

This clearly shows how consistent investing builds wealth over time.
