Example Calculation

Let’s say you invested $2,000 in a savings account or mutual fund with an annual growth rate of 7%, and you leave it for 10 years.

Step 1: Future Value Formula

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

Where:

  • rrr = annual growth rate (decimal form)
  • ttt = number of years

=2000×(1+0.07)10= 2000 \times (1 + 0.07)^{10}=2000×(1+0.07)10 =2000×(1.967)=3,934= 2000 \times (1.967) = 3,934=2000×(1.967)=3,934

Step 2: Total Gain

Gain=Future Value−Initial Value\text{Gain} = \text{Future Value} – \text{Initial Value}Gain=Future Value−Initial Value =3,934−2000=1,934= 3,934 – 2000 = 1,934=3,934−2000=1,934

Step 3: Percentage Growth

Percentage Growth=(GainInitial Value)×100\text{Percentage Growth} = \left(\frac{\text{Gain}}{\text{Initial Value}}\right) \times 100Percentage Growth=(Initial ValueGain​)×100 =(19342000)×100=96.7%= \left(\frac{1934}{2000}\right) \times 100 = 96.7\%=(20001934​)×100=96.7%

✅ After 10 years, your $2,000 would grow to $3,934, almost doubling in value.
