The Mathematical Mechanics of Compounding
Unlike simple bank interest, recurring investments leverage the Future Value of an Annuity-Due formula, where monthly contributions enter compounding cascades immediately at the start of each computational cycle.
Where P = Periodic deposit, r = monthly periodic rate (i / 12), n = total compounding months.
Where s = Annual salary hike step-up percentage (e.g. 10%), Y = total years horizon, t = index year.
The Devastating Cost of a 10-Year Delay

Total invested: C$6,300,000
+1,446% gain
Total invested: C$4,500,000
+531% gain
