Millionaire Calculator

It depends on starting balance, monthly contribution, and annual return. With this calculator's effective monthly compounding, starting from zero and contributing $500 a month at 7% annual return reaches $1 million in about 37 years and 2 months. At $1,000 a month, it takes about 28 years and 1 month. These are nominal projections, not market forecasts.

A common long-term assumption for a diversified stock-heavy portfolio is 7 percent annual after inflation, or 9 to 10 percent nominal. Bond-heavy portfolios run lower, around 4 to 5 percent nominal. Lower the assumption if you want to be conservative.

Because returns earn returns. With this calculator's end-of-month contribution timing, investing $500 per month for 30 years grows to about $584,726 at a 7% effective annual return and about $1,031,422 at 10%. The higher assumption produces about 76% more, illustrating compounding sensitivity rather than a forecast.

$1 million in 30 years is not the same as $1 million today. At 2.5 percent inflation, $1M in 30 years has the purchasing power of about $477,000 today. Toggle the inflation-adjusted option to see real (after-inflation) growth.

Most personal finance writers separate liquid investable assets (retirement, brokerage, savings) from home equity when targeting a millionaire net worth. Liquid assets can be spent in retirement; home equity is illiquid unless you sell or borrow against it.
