4% of $25,000 is $100. At that rate, it would take 25 years to double the investment. This presumes you withdraw the interest. If you reinvest the interest, it gets more complicated.

$100 first year

$104 year 2 = $208

$108.32 year 3 = 316.32

$112.65 year 4 = $428.97

$117.16 year 5 = $546.13

$121.85 year 6 = $667.98

$126.72 year 7 = $794.70

$131.79 year 8 = $926.49

$137.06 year 9 = $1063.55

$142.54 year 10 = $1206.09

$148.24 year 11 = $1354.33

$154.27 year 12 = $1508.60

$160.34 year 13 = $1668.94

$166.76 year 14 = $1835.70

$173.43 year 15 = $2009.13

$180.37 year 16 = $2189.50

$187.58 year 17 = $2377.08

$195.08 year 18 = $2572.16 That is $72.16 too much. You earn $0.54189777 per day during year 18. You need $122.92 to reach $2500 and realize double your investment. It would take about 227 days to reach that amount, which is around August 15 (not counting this a leap year). That is a little more than 62% of the 18th year.

All that just to pretty much agree with Ed1530!

Way to go ED1530!
