Climb to your goal

Balance Saved

How the millionaire calculator works

The tool runs your money forward one month at a time. Each month it applies a slice of your annual return to the current balance and then adds your contribution, so growth and saving reinforce each other. It keeps going until the balance crosses your goal, then reports the exact point you got there in years and, if you entered your age, the age you are likely to reach it.

The chart plots your balance as a rising area against the flat dashed line of money you actually saved, with a green marker at the goal. Early on the two lines hug each other; over time compounding pulls the balance well above what you put in, which is the engine that gets most savers across the finish line.

A quick example

Imagine a 30-year-old with 25,000 dollars saved who puts away 800 dollars a month and earns 7 percent a year. They cross one million dollars in their late fifties, having personally contributed roughly 270,000 dollars. The remaining bulk of the balance is pure investment growth, not money out of their own pocket.

Things to keep in mind

Returns are never smooth, so treat the result as a planning estimate rather than a date on the calendar. Inflation also erodes what a million will buy decades from now. For neutral guidance on investing for long-term goals, see Investor.gov. To project a single lump sum without monthly saving, try our compound interest calculator.

Frequently asked questions

How long does it take to save a million dollars?

It depends on your starting balance, how much you add each month, and your return. Saving 800 dollars a month from 25,000 dollars at a 7 percent annual return reaches one million in roughly 28 years. Raising the monthly amount or the return shortens that timeline noticeably.

Does the calculator account for compound growth?

Yes. It grows your balance month by month, so each month earns a return on the prior balance plus that month's contribution. This compounding is why the gap between the money you put in and your total balance widens sharply in the later years.

What return should I assume?

There is no guaranteed figure, but a diversified stock and bond portfolio has historically averaged somewhere around 6 to 8 percent a year before inflation over long periods. Using a more conservative number gives a safer, longer estimate you are less likely to fall short of.

Is one million dollars enough to retire?

It can be, but it depends on your spending, location, and other income such as a pension or social security. A common rule of thumb is that one million supports roughly 40,000 dollars of annual withdrawals, so the right target varies from person to person.
