(The 7% figure is an assumption for illustration, not a prediction; real market returns vary and can be negative.) The same $500 a month, three destinations Start with $0, add $500 every month, and let each path run for 30 years. The math below uses monthly compounding; the inflation column assumes 3% a year so the balances can be compared...
