How the investment calculator works
The calculator combines two growth drivers: your starting balance and recurring monthly contributions. It compounds returns over your chosen time horizon and estimates how much of your final balance comes from contributions versus market growth.
Understanding long-term investment growth
Investment outcomes are sensitive to time, return assumptions, and contribution consistency. Small changes in annual return can produce large differences over decades. Use this tool to stress-test conservative and optimistic scenarios before setting savings targets.
