Example Calculation

Let’s imagine you invested $5,000 in the stock market 15 years ago, with an average annual return of 8%.

Step 1: Future Value Formula

Future Value=Initial Investment×(1+r)t\text{Future Value} = \text{Initial Investment} \times (1 + r)^tFuture Value=Initial Investment×(1+r)t

Where:

  • rrr = annual growth rate (as a decimal)
  • ttt = time in years

=5000×(1+0.08)15= 5000 \times (1 + 0.08)^{15}=5000×(1+0.08)15 =5000×(3.1722)=15,861= 5000 \times (3.1722) = 15,861=5000×(3.1722)=15,861

Step 2: Total Gain

Gain=Future Value−Initial Investment\text{Gain} = \text{Future Value} – \text{Initial Investment}Gain=Future Value−Initial Investment =15,861−5000=10,861= 15,861 – 5000 = 10,861=15,861−5000=10,861

Step 3: Percentage Growth

Percentage Growth=(GainInitial Investment)×100\text{Percentage Growth} = \left(\frac{\text{Gain}}{\text{Initial Investment}}\right) \times 100Percentage Growth=(Initial InvestmentGain​)×100 =(10,8615000)×100≈217.22%= \left(\frac{10,861}{5000}\right) \times 100 \approx 217.22\%=(500010,861​)×100≈217.22%

✅ If you had invested $5,000, it would be worth $15,861 today, growing by 217% over 15 years.
