How Investment Growth Works
Investment growth uses compound returns with regular contributions to project your portfolio value.
Formula
FV = PV(1+r)^n + PMT * [(1+r)^n - 1] / r
Where:
Example Calculation
You invest $25,000 and add $500/month at 8% return for 25 years.
- 01Monthly rate: 8% / 12 = 0.6667% (0.006667)
- 02Total months: 25 * 12 = 300
- 03Initial investment grows: $25,000 * (1.006667)^300 = $171,212.89
- 04Monthly contributions grow: $500 * [(1.006667)^300 - 1] / 0.006667 = $475,513.14
- 05Future Value = $171,212.89 + $475,513.14 = $646,726.03
- 06Total invested: $25,000 + ($500 * 300) = $175,000
- 07Investment gains: $646,726.03 - $175,000 = $471,726.03
