Why an exact date matters
“Someday” is not a plan. The Millionaire Clock converts your numbers — current savings, monthly contribution, expected return — into a specific calendar day you cross $1,000,000, the age you'll be, and a live countdown in seconds. Concrete dates change behavior in a way vague goals never do.
Play with the sliders and two things become obvious. First, the violence of small changes: an extra $100 a month routinely moves the date years earlier. Second, the tyranny of the start: going from $0 to $100K takes longer than going from $500K to $1M, because compounding does the heavy lifting at the end. And for perspective, the clock also shows how many minutes it takes Elon Musk to earn whatever you still need.
FAQ
How is my millionaire date calculated?
Standard compound interest with monthly compounding: your current savings grow at your chosen annual return while your monthly contribution is added each month. We count the months until the balance crosses $1,000,000 and convert that to a calendar date — and a live countdown in seconds.
What return rate should I use?
7% is the classic assumption — roughly the S&P 500's long-run average after inflation. Use 0% to see the brutal mattress scenario, or 10-12% if you're feeling optimistic about the next few decades.
How long does it take to save $1 million from nothing?
At $500/month and 7% returns: about 36 years. Raise it to $1,000/month and it drops to roughly 26 years. The first $100K is the slowest part — compounding does most of the work in the final decade.
