Big numbers made physical
Small numbers take a second to say, but big ones like "seven hundred eighty-three thousand, four hundred sixty-two" take several. Averaged over a full count to a million, about three seconds per number is a fair estimate. That makes a million about 833 hours of counting, or roughly 104 days at eight hours a day.
Time makes the same point. A million seconds is about 11.6 days, while a billion seconds is nearly 32 years. Keep that in mind next time a news story mentions millions and billions in the same sentence.
What a million looks like in money terms
Counting is one way to feel the size of a million; money is another. A million dollars saved at $1,000 a month takes more than 83 years in cash, but about 27 and a half years if invested at an average 7% return, because growth does more of the work every year. The difference between those two numbers is the whole case for investing rather than saving in cash for long goals.
A billion is a thousand times bigger again. At three seconds a number and eight hours a day, counting to a billion would take about 285 years, and saving a billion from a salary is out of reach in any lifetime. The spend a billion calculator and the years to a million calculator put both numbers in perspective.
