How it works
Compounding means returns earn their own returns. This calculator compounds monthly: balance = start x (1 + r)^n + deposit x ((1 + r)^n - 1) / r, where r is the monthly rate and n the number of months.
Steady deposits matter as much as the rate in the early years. A constant return is an assumption and real returns vary, so use conservative numbers and treat the result as a rough guide.
