Hi guys, as per Winner69's suggestion I've come up with some ideas on what I would like to achieve and what I can contribute towards achieving this.

I am 28 years old. I have $150k to invest. I can contribute at least $20k annually towards investing.

Below is a spreadsheet I came up with. The tax rate I am using is 28%.

Year Cash Injection Age Initial 150000
1 20000 $182,240.00 29 Average Interest 7.20% 10.00%
2 20000 $216,801.28 30
3 20000 $253,850.97 31
4 20000 $293,568.24 32
5 20000 $336,145.16 33
6 20000 $381,787.61 34
7 20000 $430,716.31 35
8 20000 $483,167.89 36
9 20000 $539,395.98 37
10 20000 $599,672.49 38
11 20000 $664,288.91 39
12 20000 $733,557.71 40
Year Cash Injection Age Initial 150000
1 20000 $188,360.00 29 Average Interest 10.80% 15.00%
2 20000 $230,862.88 30
3 20000 $277,956.07 31
4 20000 $330,135.33 32
5 20000 $387,949.94 33
6 20000 $452,008.54 34
7 20000 $522,985.46 35
8 20000 $601,627.89 36
9 20000 $688,763.70 37
10 20000 $785,310.18 38
11 20000 $892,283.68 39
12 20000 $1,010,810.31 40

From my research it appears growth mutual funds target an average of 10% per annum before tax. Looking at some of the better performing funds e.g. Milford, have been achieving close to 15% over the last 5 years.

What are your thoughts on this?
