The path to a million
Becoming a millionaire is far less about a big income and far more about time, consistency, and compound growth. This calculator simulates your balance month by month until it hits your target. Try it and notice something striking: for most realistic scenarios, a large chunk of the final million is growth you never deposited — the market doing the work while you keep contributing.
Time is the hidden ingredient
The relationship between contribution and timeline isn't linear. Someone investing $1,000/month at 8% reaches $1M in about 25–26 years. Doubling to $2,000/month doesn't halve the time — it cuts it to about 19 years — because in the early scenario, compounding contributes more of the total. The lesson: starting earlier often beats contributing more, because it gives growth more time to dwarf your deposits.
Realistic assumptions
- Return: a diversified stock portfolio has historically returned ~7–10% before inflation. Using 7–8% is reasonable; remember real (after-inflation) growth is a few points lower, so tomorrow's million buys less than today's.
- Consistency beats timing. Automatic monthly investing (dollar-cost averaging) removes the temptation to time the market and keeps the compounding streak unbroken.
- Fees matter. A 1% annual fee can delay your millionaire date by years — see our investment fee impact calculator.
The number isn't magic — a million isn't what it once was — but the exercise reveals the real engine of wealth: modest, automatic, relentless investing over decades.
