Popular questions, answered with numbers
Frequently asked questions
How long does it take to save $1 million investing $500 a month?
About 36 years 5 months at a 7.0% average yearly return, starting from $0. You would put in $218,500 yourself; compound growth adds the other $784,530.
Is $1 million in 37 years really worth $1 million?
No. With 3.0% yearly inflation it would buy roughly what $340,809 buys today. That is why the calculator shows both numbers.
What return should I assume?
This calculator uses 7.0% by default — below the US stock market’s long-run average of about 10% a year before inflation, to leave room for fees and bad decades. Returns are never guaranteed and some years are negative.
What moves the date the most?
The amount you invest every month and how early you start. Raising contributions with each pay rise and keeping fees low come next. Chasing higher returns usually adds risk, not certainty.
