How the Historic Investment Calculator Works

The calculator uses historical data and compounding formulas to estimate total investment value at the end date. It accounts for growth, dividends, and reinvestments.

Basic Formula for Compound Growth:$$\text{Future Value} = P \times (1 + r)^n + \text{Additional Contributions}$$Future Value=P×(1+r)n+Additional Contributions

Where:

• $P$P = Initial investment
• $r$r = Annualized return rate
• $n$n = Number of years invested

Example Calculation:

• Initial investment: $10,000
• Annualized return: 8%
• Investment duration: 10 years

$$\text{Future Value} = 10,000 \times (1 + 0.08)^{10} \approx 21,589$$Future Value=10,000×(1+0.08)10≈21,589

Result: $21,589 after 10 years of growth.

If dividends are reinvested, the growth is compounded more quickly, reflecting total returns rather than just price appreciation.
